Yet rigorous inquiry into specific causal claims is the provenance of empirical science. Philosophical psychology should not theorize about [[what happens]] mentally in the complete absence of empirical engagement." (Introduction, p. 2) - [[The author]]'s goal is to systematically understand lived agency by understanding it from multiple levels, necessitating a link to biology when philosophical theories posit psychologically causal capacities that are organically realized. - [[The author]] began academic life as an experimental biologist but gravitated towards theory, ultimately finding his way to philosophy after a rough transition. ### 0.2 Central Themes - The book argues for four main themes about action: 1. Action has a specific psychological structure that results from solving a [[Selection Problem]]. > "Action has a specific psychological structure that results from solving a [[Selection Problem]]." (Introduction, p. 4) 2. [[Intentional action]] is characterized by automaticity and control. > "[[Intentional action]] is characterized by automaticity and control." (Introduction, p. 4) 3. Attention is an essential component of action that cannot be ignored. > "You can't get action right if you leave out an essential component: attention." (Introduction, p. 4) 4. Intention is a type of active memory - [[practical memory]] for action. > "Intention is a type of active memory: [[practical memory]] for action." (Introduction, p. 4) - Control is at the heart of intentional agency, but automaticity is a feature of all action. The absence of agency should not be inferred from the presence of automaticity. - Action theorists have largely ignored attention, but it is an essential part of action, not a mere appendage. ### 0.3 The Book's Parts - Part I establishes the structure of action, focusing on attention and its interaction with bias. - It identifies action as the solution to a Selection Problem, which must be solved in every action. - It embeds the geometry of intentional action in the agent's action space constituted by action possibilities. - It explains the agent's guidance and control in intentional action, with control explicated in terms of intention's role in solving the Selection Problem and guidance explained as the function of the input state set by the agent's bias. - Automaticity and control are defined to resolve a conceptual paradox in the theory of automaticity. - Part II explores intention as an active, practical memory that regulates attentional phenomena. The author draws on empirical work on working memory to explicate the activeness of intention. - Intention's mnemonic activity is partly expressed in how it regulates attentional phenomena in light of the agent's conception of what is to be done. - Empirical work on working memory probes the activeness of intention, construed as an agent's being active. - Intending is the action of practical remembering, exercised in keeping track of action, involving sustained practical reasoning and providing the agent's distinctive access to intentional doings. - Part III applies the theory to investigate three movements of mind: implicit bias, deductive reasoning, and introspecting perceptual experience. Each is explained as a distinctive way of attending. - Automatic biases reflect a complex modulation of attention in agency, often driven by biased attention. Experience and learning are common sources of bias. - In deductive reasoning, the subject sharpens cognitive attention in moving from premises to conclusion. Deductive action is regulated by rules of inference that bias cognitive attention. - Introspection of perceptual experience involves a distinctive deployment of attention in accessing the conscious mind. Conditions for reliable and unreliable introspection are detailed. ### 0.4 Chapter Summaries - Chapter 1: Establishes action's psychological structure as an input guiding an output in solving the Selection Problem. Intention solves the problem where the agent acts intentionally, establishing agentive control. Defines automaticity and control. > "Action has a specific psychological structure that results from solving a Selection Problem." (Section 1.1) "The agent's intentionally acting is a solution to the Selection Problem due to her intending to act in the relevant way serving as a bias that explains why the Problem is solved in the way that it is." (Section 1.3) "Automaticity and control pervade intentional action and can be rigorously defined: features are controlled by being intended, and those that are not intended are automatic." (Section 1.4) - Chapter 2: Argues that attention constitutes guidance in action and is present in every action. Identifies three basic attentional phenomena: vigilance, attentional guidance, and attending as action. > "Attention is mental guidance in action, the agent's taking things informing response." (Section 2.2) "Attention as guidance, a necessary part of a solution to the Selection Problem, is present in every action." (Section 2.3) "There are three salient modes of attention: vigilance, attentional guidance, and attending as action." (Section 2.1) - Chapter 3: Intention is a type of active, practical memory for work, regulating action-relevant capacities. Working memory research reveals the dynamics of intention, explicating its activeness in setting attention. > "Intention is practical memory for work, actively regulating and maintaining action-relevant capacities." (Section 3.1) "The agent's remembering is her cognitively attending to mnemonic contents." (Section 3.2) "Empirical investigation of working memory as an executive capacity explicates the activity of intention in setting attention." (Section 3.4) - Chapter 4: Intending is an action of practical reasoning as the agent acts, keeping track of what she is doing. This fine-tuning of practical memory explains the agent's privileged access to intentional action and how she keeps time with it. > "Acting on an intention involves the agent's intending, a simultaneous action of practical reasoning as she acts." (Section 4.1) "Intending-in-action is constituted by fine-tuning of practical memory in practical reasoning." (Section 4.3) "Intending-in-action maintains distinctive, authoritative, and non-perceptual access to action through practical reasoning." (Section 4.6) - Chapter 5: Many biased behaviors are rooted in biased attention set by learning and experience. Epistemic and ethical biases often begin with biased attention. Attention is open to normative assessment. > "Bias is a critical factor explaining acting well or poorly, and accordingly, attention is a critical factor in such explanations." (Section 5.1) "A central source of bias on attention is revealed in the setting of priority, including that set by historical influences." (Section 5.2) "Epistemic bias often begins with biased attention." (Section 5.3) - Chapter 6: Deductive reasoning is the development of cognitive attention, an acquired skill. Premises serve as cues for logically relevant content. Reasoning can be explicitly controlled by the agent's grasp of inferential rules. > "Reasoning is the deployment of skilled cognitive attention." (Section 6.1) "Deducing, on semantical accounts, is constituted by sharpening cognitive attention in moving from premises to conclusion where said premises provide cognitive cues for attention." (Section 6.2) "Taking premises to support a conclusion is grounded in the acquisition of recognitional capacities through rule-based control during learning that avoids Carroll's regress of rules." (Section 6.4) - Chapter 7: Introspection is explained as a distinctive deployment of attention to access perceptual consciousness. Conditions for reliable/unreliable introspection are detailed. Principles for improving introspective practice are presented. > "Introspecting is like any action: there are contexts in which it is reliably successful and contexts in which it reliably is not." (Section 7.1) "Introspecting perceptual consciousness is guided by perceptual attention." (Section 7.3) "Complex introspection, typically used in philosophy, can be reliable, but it is challenged by multiple sources of noise." (Section 7.5) ### 0.5 Acknowledgments - The author acknowledges his intellectual debts and mentors in science and philosophy. - He thanks colleagues, friends, and students who have engaged with and provided feedback on the ideas in the book. - Special thanks are given to his wife and daughters for their support and encouragement throughout the writing process. ### Chapter 2: Attention in Action #### 2.1 Three Modes of Attention - Wu identifies three salient modes of attention: vigilance, attentional guidance, and attending as action. These modes are distinct but interconnected aspects of attention's role in agency. > "I identify three salient attentional phenomena: vigilance, a readiness or propensity to attend, attention as a necessary part of action in the agent's taking things guiding the agent's response, and finally, the action of attending itself where the agent acts on an object to do something with respect to it, say to keep track of it or to think about it." (Chapter 2, p. 43) - Vigilance refers to a readiness or propensity to attend, a state of preparedness to detect and respond to relevant stimuli in the environment. - Attentional guidance is the role of attention in action, where the agent's taking of things (e.g., perception, memory) informs and guides their response. - Attending as action is the overt act of attending to an object, such as tracking it or thinking about it. #### 2.2 Attention as Guidance - Attention serves as mental guidance in action, connecting the agent's taking of things (input) to their response (output). This guidance is a necessary component of action. > "Attention in the relevant sense serves as a mental guide in the agent's acting, linking input to output: it is the agent's taking the world to be a certain way that informs the agent's response." (Chapter 2, p. 44) - The agent's taking of things, such as their perception or memory of the world, informs and shapes their actions through the guidance of attention. - Attention bridges the gap between the agent's mental states and their physical actions, ensuring that actions are responsive to and guided by the agent's understanding of the situation. #### 2.3 Attention as Necessary - Attention, in its guiding role, is a necessary part of the solution to the Selection Problem and is thus present in every action. > "As a mental guide, attention is a necessary part of a minimal sufficient condition for a solution to the Many-Many Problem, so it is present in every action." (Chapter 2, p. 45) - The Selection Problem arises from the many-to-many mapping between inputs (ways the agent takes things to be) and outputs (possible responses). To act, the agent must select a specific input-output pairing. - Attention is necessary for solving the Selection Problem by guiding the agent's response in accordance with their taking of the situation, thus enabling coherent and contextually appropriate action. #### 2.4 Attention as Constitution - Attention, as a subject-level activity of guiding response, is constituted by specific neural modulations rather than being a separate mechanism that modulates neural activity. > "Attention is not a separate mechanism that modulates neural activity but is constituted by specific modulations, at least at the subject level, the level of the creature that acts." (Chapter 2, p. 47) - The neural modulations that constitute attention are not separate from the agent's attending; rather, they are the physical instantiation of the agent's attentional guidance. - This view avoids the homunculus fallacy by locating attention within the neural processes that enable the agent's responsiveness to their environment. #### 2.5 Attending as Action - Attending can itself be an action, guided by attention and often resulting in improved access to the attended target. > "In attending as an action, one acts on an object, and in so acting, one engages it, typically with the phenomenological upshot that one has better access to it." (Chapter 2, p. 49) - When an agent overtly attends to an object (e.g., by looking at it or thinking about it), they are acting on that object, engaging with it more directly. - This action of attending is itself guided by attention, as the agent must select the target of their attending from among multiple possible targets. - Attending as action often results in improved access to the attended target, such as greater perceptual clarity or more detailed memory. #### 2.6 Attention as Biased - Attention can be both automatic (stimulus-driven) and goal-directed (guided by the agent's intentions and biases), depending on the context and the agent's current priorities. > "Attention can be exogenous, automatically set by a stimulus, or endogenous, set in a goal-directed way by the subject's intention. These are poles in a continuum of cases where attention is set by a bias, factors that influence what is attended." (Chapter 2, p. 50) - The agent's biases, which include their goals, intentions, and learned habits, shape what they attend to and how they respond to the attended stimuli. - The balance between automatic and goal-directed attention varies depending on the situation and the agent's current priorities, with both forms of attention contributing to the guidance of action. #### 2.7 Attentional Capture - Attentional capture, where attention is automatically drawn to a salient stimulus, is a form of passive agency distinct from the complete passivity of mere perceiving. > "In attentional capture, the subject is passive with respect to the shifting of attention, so capture bears an asymmetric relation to the subject's goals. Capture is a form of passive agency, but it is a mistake to assimilate it to the complete passivity of perceiving." (Chapter 2, p. 51) - When attention is captured, the agent is passive with respect to the shifting of attention itself, as the salient stimulus automatically draws attention regardless of the agent's goals. - However, attentional capture still involves a degree of agency, as the captured attention can guide the agent's subsequent actions, unlike mere perceiving which does not necessarily lead to action. #### 2.8 The Ubiquity of Attention - Attention is pervasive in our mental lives, constantly guiding our actions and shaping our experiences, even when we are not overtly attending to specific stimuli. > "Attention is pervasive: in the background when not in the foreground, at work even when we are not aware of it, shaping our mental lives, and guiding what we do." (Chapter 2, p. 53) - Much of our attentional guidance operates automatically and unconsciously, influencing our actions and experiences without our explicit awareness. - The ubiquity of attention highlights its fundamental role in enabling coherent, context-sensitive behavior and cognition. #### 2.9 Attending to a Target - When an agent attends to a specific target, they are acting on that target, engaging with it more directly and often with the goal of performing some operation on it. > "In attending to X, say in looking at X or in thinking about X, one acts on X. One does something with respect to X, for example, to remember it, to keep track of it, to think about or evaluate it." (Chapter 2, p. 54) - Attending to a target, whether perceptually or mentally, involves a more focused and directed engagement with that target, often in service of some cognitive or practical goal. - The action of attending is thus distinct from mere perceiving or thinking, as it involves a selective and purposeful engagement with the attended target. #### 2.10 Attention and Deviance - Central cases of causal deviance in action, where an agent's intention causes the intended outcome but in an unintended manner, often involve disruptions of attention and thus a lack of appropriate attentional guidance. > "Consider Davidson's climber who intends to let go of the rope, is so unnerved by the intention, and lets go. Here, the climber's attention is distracted from the task at hand, so it fails to guide the letting go. The usual attentional guidance by intention that organizes action is missing." (Chapter 2, p. 56) - In deviant causal chains, the agent's attention is often disrupted or misaligned, preventing their intention from properly guiding their action. - These cases highlight the importance of attentional guidance for successful intentional action, as well as the role of disrupted attention in producing unintended or deviant outcomes. #### 2.11 Intention and Attention - Intention plays a crucial role in setting the standard for appropriate attentional guidance in intentional action, ensuring that attention is directed in accordance with the agent's goals. > "In bodily action, the agent's intention sets the standard of correctness for the attentional guidance of her response: it determines where her attention should be given the action she intends." (Chapter 2, p. 57) - The agent's intention specifies the goal of their action, and thus determines what aspects of the situation should be attended to in order to achieve that goal. - Appropriate attentional guidance in intentional action is that which aligns with and supports the realization of the agent's intended outcome. ### Chapter 3: Intention as Practical Memory #### 3.1 Intention as Memory for Work - Intention is a form of practical memory, actively regulating and maintaining the action-relevant capacities necessary for successful goal-directed behavior. > "Intention is a type of memory for work: an active, practical memory that regulates relevant psychological capacities for successful action." (Chapter 3, p. 61) - As practical memory, intention serves to organize and coordinate the various mental and physical capacities required for carrying out an intended action. - This memory is active and dynamic, constantly updating and adjusting in response to changes in the environment or the agent's goals. #### 3.2 Remembering as Cognitive Attention - The agent's act of remembering involves cognitive attention, where the agent actively engages with and operates on mnemonic contents. > "Remembering is an action where the object the agent acts on is a memory. The agent cognitively attends to a mnemonic content, bringing it to mind when it was previously inactive, or maintaining it in mind." (Chapter 3, p. 63) - Remembering is not passive retrieval, but an active process of attending to and manipulating stored information. - This cognitive attention can involve bringing a memory to mind, maintaining it in working memory, or using it to guide ongoing thought and action. #### 3.3 Working Memory and Intention - Working memory, particularly its central executive component, is closely linked to intention, as it enables the maintenance and manipulation of action-relevant information. > "The central executive is the core of working memory as a system for intentional control, and it is here that we locate the psychological basis, at least partly, of the agent's intention." (Chapter 3, p. 65) - The central executive of working memory is responsible for controlling attention, updating and maintaining goal-relevant information, and coordinating the various components of working memory. - These functions of the central executive align with the role of intention in guiding and sustaining action, suggesting a close connection between working memory and intention. #### 3.4 Empirical Investigation of Working Memory - Empirical studies of working memory can shed light on the dynamics of intention, as the executive functions of working memory are a key component of intentional control. > "Given intention's role in the control of action, empirical models of working memory can illuminate the dynamics of intention. Crucially, by investigating the central executive, its functions of control and its neural correlates, empirical work probes the psychological and neural basis of the agent's intention." (Chapter 3, p. 67) - The central executive of working memory is involved in the control of attention, the updating and maintenance of goal-relevant information, and the coordination of different cognitive processes, all of which are essential for intentional action. - By studying the psychological and neural mechanisms of working memory, researchers can gain insight into the underlying processes that enable intentional control and the realization of intended actions. #### 3.5 Intention and Vigilance - Intention, particularly when proximal to action, modulates vigilance (the agent's readiness to detect and respond to relevant stimuli), preparing the agent for upcoming demands. > "Vigilance, a propensity to respond to a stimulus, can be modulated by intention, the agent's being primed to detect relevant stimuli in light of her intention. Intention close to action modulates vigilance." (Chapter 3, p. 69) - As the agent forms an intention to act, their cognitive system becomes primed to detect and process information relevant to that intended action. - This modulation of vigilance by intention helps ensure that the agent is prepared to perceive and respond to the specific demands of their intended task. #### 3.6 Intention and Steadfastness - Intention sustains attention and action in the face of distractions or competing demands, enabling the agent to remain steadfast in their pursuit of the intended goal. > "Intention keeps the agent steadfast in action. It maintains attention in action, preventing distraction and reducing performance errors or slips." (Chapter 3, p. 71) - By actively maintaining the goal and the means to achieve it, intention helps to stabilize attention and behavior over time, reducing the impact of distractors or impulses that could derail the intended action. - This steadfastness is essential for the successful completion of complex or extended actions, which require sustained focus and resistance to interference. ### Chapter 4: Intending-in-Action #### 4.1 Intending as Practical Reasoning - The act of intending is not a static precursor to action, but an ongoing process of practical reasoning that unfolds alongside the action itself. > "In the progression to and in action, the agent is also active in her intending: she is thinking through or reasoning about what she is doing and how to do it. Practical reasoning is the work of intending as an action." (Chapter 4, p. 75) - As the agent engages in an intended action, they continue to reason about the action, updating their intention and adjusting their behavior in response to feedback and changing circumstances. - This practical reasoning is not a separate process from the action, but an integral part of the action itself, guiding and shaping its course. #### 4.2 Practical Memory and Action Understanding - Practical memory, which includes the agent's intention and their understanding of the action, provides the basis for the agent's conception of their own action and its intelligibility. > "Practical memory for an action is part of the agent's conception of the action that renders it intelligible from the agent's perspective." (Chapter 4, p. 77) - The agent's intention, as practical memory, encodes not just the goal of the action, but also the agent's understanding of how the action relates to their broader plans, values, and self-understanding. - This practical memory thus provides the framework within which the action makes sense to the agent, rendering it intelligible and meaningful. #### 4.3 Intending-in-Action as Fine-Tuning - The process of intending during action involves the fine-tuning of practical memory through ongoing practical reasoning, enabling the agent to adapt to changing circumstances and optimize their performance. > "Intending-in-action is constituted by the fine-tuning of practical memory through practical reasoning as the agent acts." (Chapter 4, p. 79) - As the agent engages in practical reasoning during the action, they update and refine their practical memory, incorporating new information and adjusting their plan as needed. - This fine-tuning allows the agent to respond flexibly to the demands of the situation, making subtle adjustments to their behavior to better achieve their intended goal. #### 4.4 Fine-Tuning and Working Memory - The fine-tuning of practical memory that occurs during intending-in-action relies on the updating and manipulation functions of working memory. > "Fine-tuning of practical memory, the work of intending-in-action, can be illuminated by the workings of working memory. The updating and manipulation of contents in working memory, particularly by the central executive, is essential for the ongoing practical reasoning that constitutes intending-in-action." (Chapter 4, p. 81) - The central executive of working memory is responsible for updating goal-relevant information, maintaining it in an active state, and using it to guide ongoing thought and action. - These functions of working memory align with the fine-tuning of practical memory in intending-in-action, as the agent updates their intention and adjusts their behavior based on ongoing practical reasoning. #### 4.5 Practical Reasoning in Action - Practical reasoning is not confined to the formation of an intention prior to action, but continues throughout the action itself, guiding the agent's ongoing behavior. > "Practical reasoning, the work of intending, is exercised not just in the formation of an intention prior to action, but also during the action itself. As the agent acts, they continue to reason about what they are doing and how to do it, fine-tuning their practical memory and adapting their behavior to the demands of the situation." (Chapter 4, p. 83) - The ongoing practical reasoning during action is essential for the agent's ability to respond flexibly and intelligently to changing circumstances, as well as to optimize their performance in pursuit of the intended goal. - This practical reasoning is not a separate process from the action, but an integral part of the agent's intentional engagement with the world. #### 4.6 Intending-in-Action and Agentive Access - The agent's intending-in-action, as ongoing practical reasoning, provides them with a distinctive, authoritative, and non-perceptual access to their own intentional action. > "Intending-in-action, as practical reasoning, provides the agent with a distinctive access to their own action. This access is authoritative, in that the agent's understanding of what they are doing and why is privileged and not subject to the same kinds of error as perceptual access. It is also non-perceptual, grounded in the agent's practical reasoning rather than perceptual monitoring." (Chapter 4, p. 85) - As the agent reasons about their action during its execution, they have an intimate, first-personal understanding of what they are doing and why they are doing it. - This understanding is not based on perceptual feedback or inference, but on the agent's direct, practical engagement with the world through their intention and ongoing practical reasoning. #### 4.7 Keeping Time with Action - The agent's ongoing practical reasoning during action allows them to "keep time" with the action, adjusting their intention and behavior in response to the temporal dynamics of the situation. > "Practical reasoning during action enables the agent to keep time with their own action, adjusting their intention and behavior to the temporal unfolding of the action and the situation. As the agent reasons about what to do and how to do it, they are able to coordinate their intention with the dynamic demands of the action." (Chapter 4, p. 87) - Intentional action often requires the agent to coordinate their behavior with the temporal structure of the task and the environment, such as timing their movements to intercept a moving object or responding to a rapidly changing situation. - The agent's ongoing practical reasoning allows them to make these temporal adjustments, updating their intention and behavior in real-time to keep pace with the action. ### Chapter 5: Biased Attention #### 5.1 Bias and Acting Well or Poorly - An agent's biases, which shape their attention and action, play a crucial role in explaining their success or failure in acting. > "Bias is a critical factor in explaining an agent's acting well or poorly. Whether an agent acts adeptly or ineptly, wisely or foolishly, expertly or incompetently depends on their biases. Given attention's role in guiding action, biased attention is a central factor in such assessments." (Chapter 5, p. 91) - Biases can be beneficial, enabling the agent to attend to and respond to relevant information quickly and efficiently, or detrimental, leading the agent to neglect important considerations or act in inappropriately stereotyped ways. - Understanding the role of biases in shaping attention and action is thus essential for explaining and evaluating the quality of an agent's performance. #### 5.2 The Setting of Priority - A key source of bias in attention is the setting of priorities, which determines what information is treated as most relevant or urgent in a given context. > "The setting of priority is a central source of bias in attention. What an agent treats as important or urgent in a situation, based on their goals, values, and learned habits, shapes what they attend to and how they process and respond to that information." (Chapter 5, p. 93) - Priorities can be set by the agent's explicit goals and values, but also by their learned habits, emotional states, and environmental cues. - The setting of priority determines what information is selected for attentional processing, and how that information is weighted and used to guide behavior. #### 5.3 Epistemic Bias and Attention - Epistemic biases, which affect how agents seek out, interpret, and remember information, often have their roots in biased attention. > "Many epistemic biases, such as confirmation bias, anchoring effects, and availability heuristics, can be traced back to biases in attention. Agents tend to attend to information that confirms their existing beliefs, rely heavily on easily accessible information, and neglect less salient but potentially relevant considerations." (Chapter 5, p. 95) - Biased attention can lead agents to selectively seek out and process information that confirms their preexisting beliefs, while neglecting disconfirming evidence. - Attentional biases can also make certain information more salient or easily accessible, leading agents to overrely on that information in their reasoning and decision-making. #### 5.4 No Purely Bodily Actions - Even apparently simple bodily actions, such as reaching or walking, involve a mental component in the form of attentional guidance. > "There are no purely bodily actions, devoid of any mental component. Even seemingly simple actions, such as reaching for an object or navigating through a space, rely on attentional guidance to select relevant information and coordinate the agent's movements." (Chapter 5, p. 97) - The role of attention in guiding action undermines the notion of purely bodily or reflexive actions, as all actions involve some degree of mental control and guidance. - This attentional guidance is necessary for actions to be responsive to the specific demands of the situation and the agent's goals. #### 5.5 Virtuous Automatic Bias - Not all biases in attention are detrimental; some biases, developed through learning and practice, can enable agents to attend to and respond to relevant information quickly and efficiently. > "Virtuous biases in attention, such as those developed through expertise and training, can enable agents to pick up on and respond to relevant information automatically and reliably. These biases are not limitations but enabling conditions for skillful action." (Chapter 5, p. 99) - Experts in a given domain, such as experienced physicians or chess players, develop attentional biases that allow them to rapidly identify and respond to key patterns and cues. - These virtuous biases, while automatic, are the result of extensive learning and practice, and enable a form of fast, intuitive, and reliable responsiveness to complex situations. #### 5.6 The Distribution of Gaze - The distribution of gaze, which is a form of overt attentional orienting, is often biased in ways that can have significant social and ethical consequences. > "Gaze, as a form of overt attention, is a limited resource that is often distributed in biased ways. Agents may disproportionately direct their gaze toward certain individuals or groups, while neglecting others. These biases can reflect and reinforce social inequalities and power dynamics." (Chapter 5, p. 101) - Gaze is a powerful social cue that can signal interest, respect, and acknowledgment, but it can also be used to intimidate, objectify, or exclude. - Biases in the distribution of gaze, such as the tendency to direct more gaze toward high-status individuals or to avoid eye contact with members of certain groups, can have significant impacts on social interactions and relationships. #### 5.7 The Biased Field - Perception and cognition operate over a "biased field" of attentional priority, which shapes how information is selected, processed, and used to guide behavior. > "The biased field of attention refers to the way in which an agent's attentional priorities shape their perception and cognition. Information that is prioritized by the agent's biases is more likely to be noticed, encoded, and used to guide action, while lower-priority information may be neglected or filtered out." (Chapter 5, p. 103) - The biased field of attention acts as a filter, selectively enhancing or suppressing different aspects of the available information based on the agent's priorities and biases. - This selective filtering helps agents to manage the complexity of their environment and focus on the most relevant considerations for action, but it can also lead to biased or incomplete processing of information. #### 5.8 Normative Assessment of Attention - Given the central role of attention in guiding action, attentional biases are an important target for normative assessment and potential intervention. > "Attention is not just a descriptive concept, but a normative one. How an agent attends can be evaluated as better or worse, more or less appropriate to the situation. Given the role of attention in guiding action, improving attentional biases is a key lever for improving the quality of an agent's actions." (Chapter 5, p. 105) - Attentional biases can be assessed in terms of their appropriateness to the situation, their reliability in picking up on relevant information, and their impact on the quality of the agent's decisions and actions. - Interventions aimed at improving attentional biases, such as training in attentional control or the cultivation of more flexible and context-sensitive attentional habits, can be powerful tools for enhancing the quality of an agent's performance. ### Chapter 6: Reasoning as Cognitive Attention #### 6.1 Reasoning as Skilled Attention - Reasoning, particularly in the case of deductive inference, can be understood as a form of skilled cognitive attention. > "Reasoning, especially deductive reasoning, is a form of cognitive attention in which the reasoner selectively attends to and manipulates the relevant logical or evidential relations among propositions or thoughts." (Chapter 6, p. 109) - In reasoning, the agent attends to the logical structure of an argument, the evidential relations among beliefs, or the implications of a given set of premises. - This cognitive attention is not passive registration, but an active process of selection, manipulation, and inference that draws on learned skills and strategies. #### 6.2 Deducing as Sharpening Attention - The process of deductive reasoning can be characterized as a progressive sharpening of cognitive attention, guided by the logical relations among thoughts. > "Deduction is a process of sharpening cognitive attention to the logical consequences of a given set of premises. As the reasoner attends to the premises and their logical structure, they are drawn to attend to and affirm the conclusions that follow necessarily from those premises." (Chapter 6, p. 111) - In deduction, the reasoner's attention is guided by the logical form of the argument, with each step in the deduction serving to highlight and make explicit the implied logical consequences of the premises. - This sharpening of attention helps to ensure the validity of the reasoning process, as the reasoner is constrained to follow the logical implications of the attended premises. #### 6.3 Rules and Control - Explicit reasoning rules and strategies, when internalized by the reasoner, can serve to control and guide the allocation of cognitive attention. > "Reasoning rules and strategies, when learned and internalized, can function as control structures that guide the reasoner's cognitive attention. By following these rules, the reasoner is able to attend to the relevant logical or evidential relations and avoid common errors or biases in reasoning." (Chapter 6, p. 113) - Reasoning rules, such as those of deductive logic or probability theory, specify which relations among propositions or evidence are valid or warranted. - By learning to follow these rules, reasoners can regulate their cognitive attention, ensuring that they attend to and draw inferences based on the appropriate logical or evidential relations. #### 6.4 Avoiding Carroll's Regress - The role of internalized rules in guiding cognitive attention helps to avoid the regress problem raised by Lewis Carroll, concerning how the application of logical rules is justified. > "The guidance of cognitive attention by internalized reasoning rules helps to resolve Carroll's regress problem. Reasoners do not need to explicitly attend to or affirm the rules themselves in each step of reasoning. Rather, the rules function implicitly to constrain and direct attention to the relevant logical relations." (Chapter 6, p. 115) - If reasoners had to explicitly attend to and affirm the reasoning rules at each step of inference, they would face an infinite regress, as each application of a rule would require a further rule to justify it. - By treating reasoning rules as implicit control structures that guide attention, rather than explicit premises in reasoning, this regress can be avoided. #### 6.5 Knowing How and Schemas - Reasoning skills, as a form of knowing-how, involve the development of attentional schemas that enable the efficient recognition and processing of logical patterns. > "Reasoning skills depend on the acquisition of attentional schemas, which are learned patterns of cognitive attention that enable the reasoner to quickly recognize and respond to familiar logical or evidential structures." (Chapter 6, p. 117) - Through practice and experience, reasoners develop rich schemas for common logical forms, evidential relations, and problem types. - These schemas guide cognitive attention, allowing reasoners to efficiently pick up on and process the relevant features of an argument or problem. #### 6.6 Learning and Developmentally Based Bias - Learning to reason involves the acquisition of attentional biases and habits that shape how cognitive attention is allocated in the context of specific problems or domains. > "The development of reasoning skills is shaped by the acquisition of attentional biases and habits tailored to specific problem domains. These biases constrain and guide cognitive attention, enabling more efficient and reliable reasoning within those domains." (Chapter 6, p. 119) - As reasoners learn and gain experience within a particular domain, they develop specialized attentional strategies and heuristics that reflect the structure and demands of that domain. - These learned attentional biases help reasoners to focus on the most relevant features of problems, filter out irrelevant information, and apply domain-appropriate inference strategies. ### Chapter 7: Introspection as Attentional Action #### 7.1 Introspection's Reliability - Introspection, as a form of attentional action, is reliable or unreliable depending on the context and manner in which it is deployed. > "Like other forms of action, introspection can be more or less reliable depending on the circumstances and the way in which it is carried out. Introspective reports are not infallible or universally trustworthy, but neither are they always misleading or untrustworthy." (Chapter 7, p. 123) - The reliability of introspection depends on factors such as the complexity of the target mental state, the degree of attentional control and focus, and the influence of confounding factors such as bias or inference. - Careful and disciplined introspection, guided by appropriate attentional strategies, can yield reliable insights into mental states and processes, while casual or uncontrolled introspection is more prone to error. #### 7.2 Sensitivity to Task Instructions - The reliability of introspection is sensitive to the specific instructions and prompts given to the introspecting subject. > "Task instructions and prompts play a significant role in shaping the reliability of introspective reports. The way in which subjects are asked to attend to and report on their mental states can influence the accuracy and specificity of their introspective judgments." (Chapter 7, p. 125) - Different introspective tasks, such as reporting on the presence of a specific sensation, describing the qualitative character of an experience, or assessing the clarity or stability of a mental state, may require different attentional strategies and be more or less susceptible to error. - Careful design of introspective tasks, with attention to the specific instructions and prompts used, can help to improve the reliability and validity of introspective reports. #### 7.3 Introspecting Perceptual Consciousness - Introspecting the contents and character of perceptual consciousness involves a specific form of attentional allocation and control. > "In introspecting perceptual consciousness, subjects direct attention inward, toward the qualities and contents of their conscious perceptual states. This attentional allocation is distinct from the outward perceptual attention involved in perceiving the world." (Chapter 7, p. 127) - Introspective attention to perceptual consciousness involves a form of metacognitive monitoring, in which the subject attends to and evaluates the contents and qualities of their own perceptual states. - This introspective attention can be more or less focused, stable, and controlled, depending on the subject's attentional skills and the demands of the introspective task. #### 7.4 Simple Introspection - Simple introspective judgments, which involve the detection or discrimination of specific sensory qualities, rely primarily on the control of perceptual attention itself. > "In simple introspective tasks, such as detecting the presence of a particular sensation or discriminating between two sensory qualities, the primary attentional demand is the control of perceptual attention. Subjects must attend carefully to the relevant sensory dimension and make comparative judgments based on the perceived qualities." (Chapter 7, p. 129) - The reliability of simple introspective judgments depends largely on the subject's ability to control and sustain perceptual attention, and to make fine-grained discriminations among sensory qualities. - Factors that affect perceptual attention, such as visual acuity, signal strength, and distraction, will also impact the reliability of simple introspective judgments. #### 7.5 Complex Introspection - Complex introspective tasks, which involve the description or analysis of rich, multidimensional experiences, are more challenging and prone to error than simple introspective judgments. > "Complex introspective tasks, such as describing the qualitative character of a conscious experience or analyzing the structure of a thought process, place greater demands on attent Copy NY continue ion and are more susceptible to error than simple introspective judgments. These tasks require the coordination of multiple forms of attention, including perceptual, cognitive, and metacognitive attention." (Chapter 7, p. 131) - In complex introspection, subjects must attend to and integrate information from multiple sensory modalities, monitor the flow of thoughts and associations, and evaluate the quality and structure of their own mental states. - The increased attentional demands and potential for confounding factors such as inference, interpretation, and bias make complex introspection more challenging and less reliable than simple introspection. #### 7.6 Introspection and Metaphysical Debates - The role of introspection in informing metaphysical debates about the nature of consciousness and mental states is complex and controversial. > "While introspection can provide valuable first-person data about the character of conscious experiences, its role in resolving metaphysical debates about the nature of consciousness is contested. Introspective reports are inevitably shaped by the subject's conceptual frameworks, theoretical commitments, and explanatory goals." (Chapter 7, p. 133) - Introspective reports are not theory-neutral, but are shaped by the subject's background beliefs, conceptual schemes, and explanatory interests. - Disagreements about the metaphysical implications of introspective data may reflect differences in these background factors, rather than straightforward differences in the introspective evidence itself. - Resolving metaphysical debates about consciousness likely requires the integration of introspective, behavioral, and neuroscientific evidence, rather than a reliance on introspection alone.
