Study Notes
Eye-Tracking and Response Time
- Complexity of an object correlates with the number of its sub-parts; more complex objects require longer response times based on eye-tracking data.
- Involves encoding a rotated image, storing it in working memory, and incrementally rotating it toward the target image based on fixation.
- The model predicts increase in response time as rotation difference between objects grows.
Ebbinghaus and Memory
- Herman Ebbinghaus studied memory retention using nonsense syllables (e.g., DAX).
- Found a 'percent savings' measure to evaluate information retention over time; shorter intervals led to higher retention percentages.
- Memory decay is rapid within the first two days, then plateaus.
Behaviorism
- Focuses on observable behavior rather than internal mental processes.
- Skinner's operant conditioning showed that variable reinforcement leads to stronger learning responses.
- Edward Tolman's work demonstrated rats form cognitive maps in mazes, challenging strict behaviorist perspectives.
Rule-Learning Studies
- Bruner, Goodnow, and Austin explored hypothesis testing in conceptual representation.
- Variability in target category attributes affects how hypotheses are tested and learned about categories.
Learning Logical Concepts
- Increased category complexity reduces accurate identification of category allocations within a given time frame.
Hypothesis Testing Strategies
- Simultaneous Scanning: Evaluates all attributes at once, ensuring no irrelevant attributes are included.
- Successive Scanning: Involves checking one attribute at a time; less efficient due to longer durations.
- Conservative Focusing: Tests one attribute per trial; feedback informs potential exclusion.
- Focus Gambling: Changes all but one attribute for efficient testing, but low probability of receiving affirmative feedback.
Typicality and Generalization
- Generalization is more robust for typical category members; depends on conclusion category size and premise variability.
R-W Model and Blocking
- First stimulus association strength increases until a limit, while later stimuli show minimal growth due to prior associations.
- Surprise is crucial for learning—unexpected cues lead to faster acquisition of associations.
Selective Attention in Learning
- Blocking Effect: Attention is directed away from novel cues due to a pre-existing perfect predictor.
- Highlighting Effect: Attention shifts to a surprising, previously known cue, strengthening its association with new information.
- Demanding attentional requirements make category learning more challenging; higher complexity leads to slower learning and more errors.
Evidence of Early Selection
- Early studies involve dual tasks demonstrating that unattended stimuli are not fully blocked, but rather attenuated.
- Participants show some awareness of information from the unattended channel, supporting a filter model of attention.
Critiques of Early Selection
- Filters require significant knowledge to differentiate stimuli effectively, leading to arguments for late selection theories.
Late Selection Theory
- Posits that filtering occurs after semantic analysis and before conscious awareness.
- Recognition necessitates both stimulus-driven and conceptually driven selection mechanisms for conscious processing.
Evidence for Late Selection
- Studies indicate semantic processing occurs at an unconscious level for unattended stimuli, revealing dual-channel phenomena.
Balint's Syndrome
- Characterized by an inability to focus on individual objects due to bilateral lesions in parietal and/or occipital cortex; leads to simultanagnosia and illusionary conjunctions.
Space-Based vs. Object-Based Attention
- Attention primarily aligns with the 'where' pathway; neglect is often left-side focused in space-based attention.
- Inhibition of return indicates slower reaction times at previously cued locations, attributed to the associated objects.
Object-Based Inhibition of Return
- Research shows that inhibition of return follows object cues rather than spatial markers, emphasizing the role of perceptual objects.
Object-Based Neglect
- Investigates whether neglect arises from space or object perception; findings indicate neglect is object-based, tracking neglected aspects across spatial transformations.
