Study Notes
Perception: Visual Perception and Imagery
- The brain has two pathways of visual processing: the dorsal stream (perception of spatial location) and ventral stream (perception of form)
- David Marr's tri-level hypothesis emphasizes the importance of understanding how cognitive processes are implemented in the brain
- The two pathways of visual processing involve the interconnected regions of the visual cortex, including the striate cortex, posterior parietal cortex, and inferior temporal cortex
- Perception of spatial location and form are processed separately and simultaneously in the brain
Mental Representations and Storage
- Analog code vs. propositional code: debate on whether mental representations are stored as images or as abstract propositions
- Research supports the analog viewpoint, but some people on some tasks use a propositional code
- Neural correlates of visual and verbal cognitive styles have been found in brain regions such as the fusiform gyrus and supramarginal gyrus
Blindness and Blindsight
- Blindsight: ability to respond to visual stimuli without conscious awareness
- Primary visual cortex and simple cells are involved in the processing of visual information
- Extrastriate cortex is involved in depth perception and color coding
The Tri-Level Hypothesis
- Computational level: highest, most abstract level of information processing
- The tri-level hypothesis emphasizes the importance of understanding how cognitive processes are implemented in the brain
Auditory Perception: Effects of Music on Cognition

- Types of long-term memory: explicit memory (conscious recall) and implicit memory (unconscious recall)
- Neurobiology of memory processing: long-term potentiation, hippocampus, and frontal lobes
- Memory disorders: evidence for separate memory systems, including Alzheimer's disease
Forgetting and Memory as Reconstruction

- Reconsolidation: rewriting of memories through retrieval and re-storage
Savant Syndrome and Hyperthymesia
- Savant syndrome: exceptional abilities in one intellectual domain, such as music, art, or mathematics
- Hyperthymesia: exceptional memory abilities
Scientific Explanations of Déjà Vu
- Various theories, including neurological and psychological explanations### Three-Stage Model of Memory
- The three-stage model of memory, also known as the Atkinson-Shiffrin model, consists of:
- Sensory memory: Holds sensory information briefly (1/2 to 4 seconds) with a large capacity store.
- Working memory or short-term memory: Processes information from sensory memory.
- Long-term memory: Stores information for an extended period.
Sensory Memory
- Sensory memory is a brief storage of sensory information that allows for selection and processing of information.
- It is often considered a part of perception.
- There are two types of sensory memory:
- Iconic memory (photographic memory): Visual sensory memory.
- Echoic memory: Auditory sensory memory.
Eidetic Imagery
- Eidetic imagery, also known as photographic memory, is a rare ability to recall visual scenes in great detail.
- Research has shown that some individuals, including children, can exhibit this ability.
Neuroscience and the Law
- The use of neuroscientific evidence in legal defense is becoming increasingly important.
- Lesions of the amygdala may cause loss of ability to learn fear conditioning and may also play a role in aggressive behavior.
- Neurosurgeries can remove tumors that affect behavior, raising questions about the legal ramifications of such procedures.
Neurolaw
- Neurolaw is an interdisciplinary field that explores the effects of new research findings in cognitive science on forensic psychiatry and legal practice.
- It includes:
- Eyewitness testimony.
- Lie detection methods.
- Use of neuroscientific evidence for legal defense or to predict criminal behavior.
- Use of neuroscience-based interventions to diminish the risk of an offender reoffending.
- Use of nootropics or mind-enhancing drugs to boost performance.

- ACT-R is a hybrid cognitive architecture that incorporates both symbolic and subsymbolic information processing.
- It consists of:
- Perceptual-motor layer.
- Pattern-matching module.
- Buffer.
- Production rules.
- ACT-R is used to model human cognition and decision-making.
Cheater Detection Module
- The cheater detection module is a theory that explains why people are better at reasoning with deontic conditionals (related to permissions, entitlements, and prohibitions) than with non-deontic conditionals.
- This module is thought to be a specialized module for monitoring social exchanges and detecting cheaters.
Object Permanence and Reasoning in Infancy
- Object permanence is the understanding that objects continue to exist even when they are hidden from view.
- Research has shown that infants as young as 3.5 months of age understand object permanence.
- Infants' folk physics (innate understanding of basic principles governing the behavior of physical objects) differs from adult folk physics in certain ways.
Modeling Object Permanence
- Object permanence can be modeled using recurrent neural networks (RNNs).
- RNNs are designed to deal with time series and sequence data.
- They can be used to model object permanence by predicting the reappearance of occluded objects.
Development of Self-Recognition
- The rouge test is a method used to assess self-recognition in children.
- Children typically pass the rouge test around 18-24 months of age.
- Only a few other animals, including apes, dolphins, and elephants, are capable of passing the rouge test.
Mindreading
- Mindreading is the ability to understand other people's mental states.
- It is critical for human social interaction.
- Pretend play, which emerges around 14 months of age, is a major milestone in the development of mindreading.
- Children with autism spectrum disorder show impairments in mindreading.
False Belief Task
- The false belief task is a test used to assess children's theory of mind mechanism (TOMM).
- Children typically pass the false belief task around 4 years of age.
- Research has shown that children may develop an implicit understanding of false belief earlier, around 15 months of age.### Cognitive Development
- Infants who have had experience crawling develop wariness of heights by 6-7 months old, as shown in the visual cliff experiment
- Piagettian stages of cognitive development:
- Sensorimotor stage (birth - 2 years): Children act on objects, coordinate sensory experiences, and form schemas about objects
- Pre-operational stage (ages 2-7): Children develop ability to symbolize objects and events, engage in pretend play, and have egocentric thinking
- Concrete operations stage (7-11): Children develop higher-order schemas, understand reversible consequences of actions, and conserve liquid quantity, mass, and number
- Formal operations stage (over age 11): Children develop ability to engage in hypothetical and deductive reasoning and think about abstract concepts
Object Permanence and Reasoning in Infancy
- Understanding that an object continues to exist even though it is out of sight is a major accomplishment of the sensorimotor stage
- Infants do not understand object permanence, which is why they respond to the game of peek-a-boo
- Infants also won't reach under a cloth for a hidden toy, demonstrating their lack of understanding of object permanence
Mindreading
- Pretend play is a way for children to develop their ability to understand other people's mental states
- False belief task: children are told a story about a character who has a false belief, and are then asked to predict what the character will do
- Theory of mind mechanism and shared attention mechanism are important for understanding other people's mental states
Strengths and Weaknesses of Piagettian Theory
- Strengths: provides a good overview of children's thinking at different points, and is based on fascinating observations
- Weaknesses: stage model depicts children's thinking as being more consistent than it actually is
