    Study Notes

    Grouping by Similarity

    • Objects perceived similarly are interpreted as having the same 3D orientation.

    Chomsky's Proposal

    • Linguistic capacities are linked to biological endowment, developed quickly in human evolution.
    • Hypothesis suggests a sudden emergence rather than gradual evolution of communication systems.

    Perception and Cognition

    • Visual Illusions: Awareness of illusions does not alter actual perception, highlighting conflict between perceived reality and knowledge.
    • Perception: Fundamental information processing initiated by sensory inputs, organizing information in the brain rapidly.
    • Cognition: Encompasses all non-perceptual processes, including thought and retrieval based on past experiences and beliefs.

    Knowledge Disputes

    • Tension exists between:
      • Beliefs or knowledge about the world.
      • Information from perceptual systems.

    Information Processing Stages

    • Perception: Fast, automatic processing independent of beliefs.
    • Cognition: Involves complex mental representations and processes related to knowledge usage.

    Knowledge Types

    • Explicit Knowledge: Declarative memory (semantic and episodic).
    • Implicit Knowledge: Non-declarative memory (conditioned responses, skills, and habits).

    Representation

    • Represents encoding of information in the brain, involved in activities like recognition and decision-making.
    • Conscious Processes: Retrieval of information and behavior driven by intentions.
    • Unconscious Processes: Implicit knowledge influencing behavior without awareness.

    Propositions and Mechanisms

    • Propositions represent thoughts about events and states in the world.
    • Cognitive mechanisms resemble computer algorithms in function, interpreting data and decisions.

    Cognitive Mechanisms

    • Correlate to neuronal events; understanding requires studying neuronal structure and functionality.
    • Examining cognitive events' neuronal underpinnings provides insight into cognitive phenomena.

    Limitations in Understanding

    • While physiological processes underlie cognition, cognitive processes must be regarded as autonomous for explanatory purposes.
    • Understanding neuronal properties does not equate to understanding what they represent.

    Representations and Cognitive Processes

    • Cognitive processes operate on conceptual representations, essential for explaining cognition.
    • Concepts serve as units of meaning, integral to higher cognitive functions.

    Levels of Analysis: Computation, Algorithms, and the Brain

    • Computational Theory (Marr): Outlines goals and structures for cognitive processes, converting tasks into computational problems.
    • Representation and Algorithm Levels: Focus on how input/output representations are encoded and manipulated within the brain.
    • Implementation Level: Addresses the physical hardware where cognitive processes materialize, requiring algorithms to fit neurological capabilities.

    Interrelation of Analysis Levels

    • The three levels (computation, algorithms, implementation) are interdependent; each constrains the others.
    • Validity of cognitive processes emerges primarily at the implementation level, where empirical proposals meet neurophysiological realities.

    Cognition and Knowledge

    • Cognition involves mental processes used for tasks such as attention and perception, and includes mechanisms that cannot be directly observed.
    • Knowledge enables human behaviors like encoding memories and language production, divided into explicit (declarative) and implicit (non-declarative) memory.
    • Explicit memory includes semantic (facts) and episodic (personal experiences), while implicit memory includes skills, conditioning, and sensory memory.

    Representation and Propositions

    • Representation refers to how information is encoded in the brain, utilized in activities such as recognizing objects and making decisions.
    • Propositions are thoughts that represent states and events, structured similarly to computer code.

    Mechanisms in Cognition

    • Cognitive mechanisms resemble computer operations, following predefined rules (algorithms) to interpret information.
    • Examples include transforming 2D lines into 3D models based on spatial relationships.

    Chomsky's Linguistic Theory

    • Chomsky argues that linguistic capacity is biologically inherent and developed recently, fundamentally influencing our cognitive systems.

    Perception and Information Processing

    • Visual illusions highlight a disconnect between perception and knowledge, as understanding an illusion does not alter its appearance.
    • Two main stages of information processing: Perception (quick, automatic) and higher-order Thinking (slow, deliberate).

    Explicit vs. Implicit Knowledge

    • Explicit knowledge is conscious, intentional, and declarative, ranging from factual to autobiographical memories.
    • Implicit knowledge includes automatic, unconscious processes essential for basic functions, not directly accessible to introspection.

    Behavior and Knowledge

    • Behavior reflects underlying cognitive processes, with explicit knowledge guiding decisions and actions intentionally.
    • Implicit knowledge operates autonomously, influencing behavior without conscious awareness.

    Studying Knowledge in the Brain

    • Investigations into cognition utilize approaches from physics and chemistry, focusing on neurons and neurotransmitters.
    • Understanding cognitive processes requires considering both physiological and representational aspects of cognition.

    Representation and Cognitive Processes

    • Cognitive processes utilize conceptual representations, essential for understanding higher cognition and how meaning is encoded.
    • Concepts act as units of meaning and inform various cognitive functions.

    Levels of Analysis: Computation, Algorithms, and Brain

    • Marr's Computational Theory defines the object of study and the functional architecture needed for cognitive processes.
    • Representation and algorithm levels analyze input/output transformations, detailing how the brain encodes and manipulates information.
    • Implementation level focuses on the physical hardware and neurophysiology that enable cognitive processes, ensuring algorithms can operate within the brain's structure.
    • These levels of analysis inform and constrain one another, merging theoretical constructs with empirical cognitive phenomena.
