Study Notes

Metacognition Lecture Series

  • The series covers topics including: introduction to metacognition, measuring metacognition, metacognition and psychopathology, metacognition and belief structures, neural correlates of metacognition, evolution and metacognition in other species, presentations/discussions, metacognition and consciousness, improving metacognition, and the limits of self-knowledge.

Metacognition - Assessment

  • Level 4 Coursework: One 2500-word assignment due November 13th. Describe and critically evaluate two studies linking metacognition to psychological traits (belief structures, psychopathology).
  • Level 4 Exam: 2-hour on-campus exam at the end of the semester. Worth 60% of the module grade.
  • Level 5 Coursework: Two 2500-word assignments, each worth 50% of the module grade.
  • First assignment due Friday November 15th (12 noon).
  • Second assignment due Friday November 29th (12 noon).
  • First assignment: Describe and critically evaluate two studies linking metacognition to other psychological traits (belief structures, psychopathology).
  • Second assignment: Does metacognition depend on different mechanisms than cognitive performance? Consider evidence from behavioral, neuroimaging, and/or lesion studies.

What to Study

  • Lecture notes provided by the lecturer will be crucial.
  • Relevant papers for each lecture will be uploaded to MyDundee.

Consciousness

  • Refers to the state of being aware of one's surroundings and internal experiences, commonly associated with heightened arousal and wakefulness.
  • An experience or mental entity is considered 'phenomenally conscious' when there is something "it's like" to have that experience.

The Hard Problem

  • A fundamental problem in neuroscience and psychology concerning subjective, first-person conscious experience (qualia).
  • No intelligible causal relationship between physiological states and the experience of subjective qualities (qualia) has been proposed.
  • Even if you knew all the physical actions behind pain or seeing red, the actual experience of pain or the color red would remain a mystery to you.

Functionalism

  • A philosophical perspective positing that mental states are determined by causal relations to sensory input, other thoughts/feelings, and behavior.
  • A functionalist might explain pain as resulting from injury leading to beliefs of physical wrongness and desires to alleviate the pain.

Critiques of Functionalism

  • Critiques from thinkers like Ned Block argue that a system with the same behavioral response to pain as a human doesn't necessarily need to experience or be aware of that pain.

The Hard Problem: Additional Insights

  • David Chalmers labeled the discrepancy between subjective experience and its underlying physical basis as the "hard problem" of consciousness.
  • Thomas Nagel highlighted that science cannot describe what it's like to be another subject and experience the world from that perspective.

Metacognition As A Step Toward Explaining Phenomenology

  • Metacognition may provide insights into the hard problem of consciousness. Proposed by Megan Peters as a small step to understanding subjective experience.

Metacognitive Properties (M-STEP)

  • Peters proposed that certain metacognitive attributes are helpful. These included:
  • Conceptual: Confidence has a subjective experience.
  • Practical: Confidence is about internal representations.
  • Conceptual and Practical: Confidence is recursive, builds on past processing.
  • Practical: Metacognition is measurable by mathematical models and linked to behavior.
  • Practical: Confidence computations are hierarchical and falsifiable.

David Marr's Levels Of Analysis

  • Marr's levels of analysis provide a useful framework for understanding any information processing system, broken down into:
  • The computational problem
  • The algorithm
  • The implementation (usually in the brain).

The Case of Blindsight

  • Blindsight is a condition demonstrating residual visual abilities despite damage to the primary visual cortex, leading to a lack of conscious visual awareness.
  • Despite the lack of conscious awareness, blindsight patients can sometimes show behaviors based on the presence or absence of stimuli they aren’t consciously aware of.

Unconscious Stimuli and Metacognition

  • Vlassova et al. showed how unconscious stimuli can influence perceptual accuracy in healthy participants. These unconscious stimuli do impact perception, but not necessarily metacognition.

Criticisms of Michel's Position on Measuring Consciousness

  • Factors other than conscious awareness affect metacognitive efficiency.
  • Experiments about consciousness using metacognition might need to be more tightly controlled.
  • Metacognitive inefficiency might not necessarily indicate unconsciousness but only lack of accessible information for metacognition;

Additional Metacognition-Consciousness Discussion Points

  • Can confidence-based tasks correctly assess whether stimuli are perceived consciously or unconsciously if other factors can affect metacognitive efficiency?
  • Examples of situations where metacognition may not correlate with conscious awareness.
