Study Notes

Visual Memory & Attention

Visual Habituation: Infants decrease looking time at repeated stimuli, showing recognition.
Infant Control Procedure (ICP): Infants control stimulus exposure duration, allowing accurate habituation assessment.
Comparator Model: The brain compares incoming stimuli to existing representations, leading to habituation or orienting responses.
Speed of Processing Hypothesis: Faster looking times suggest quicker information processing in infants.
Disengagement Hypothesis: Faster disengagement from stimuli correlates with shorter looking times in infants.
Sustained Attention: Focused attention on a stimulus, often accompanied by heart rate deceleration.
Attention Termination: Infants disengage from a stimulus, often accompanied by heart rate recovery.
RFN Model (Random-Familiar-Novel): Infants' visual preferences sequence from random, to familiar, to novel stimuli during habituation.
Goldilocks Effect: Infants prefer moderately complex and predictable stimuli, avoiding overly simple or complex ones.
Familiarity Preference: Increased attention to partially familiar stimuli may aid learning and memory consolidation.
Object Permanence: Continued understanding that objects exist when out of sight. This directly relates to Piaget's cognitive development theory.

Symbolic Representation & Error

Symbolic Representation: The ability to mentally represent objects and events not physically present, developing around 18 months of age (according to Piaget).
A-not-B Error: Infants search for a hidden object in a previously successful location (location A) even if they've observed the object moved to another location (location B). This suggests incomplete object permanence
Violation-of-Expectation (VoE) Paradigm: Infants display longer looking times at impossible events, indicating an understanding of physical principles. Used to study infant cognition.
Solidity: The principle that two solid objects cannot occupy the same space.
Continuity: The principle of an object tracing a single path over space and time.
Event Categories: Infants organize physical events (occlusion, containment, collisions, and support) into categories.
Support Events: Infants understand an object being supported by another object, gradually developing this concept from simple contact.
Physical Reasoning System (PRS): Infants use innate causal frameworks to understand physical events.
Contrastive Learning: Infants evaluate the effects of different variable values to understand things like height (e.g. object visibility).
Priming: Exposing infants to a particular event to highlight a specific variable helps them integrate it into their representations of similar events.

Encoding, Retrieval & VoE

Encoding: The process of creating a mental representation of an event.
Retrieval: The process of accessing encoded information in memory.
Violation of Expectation (VoE): This paradigm assesses infant cognition by measuring looking times at events that either confirm or violate expectations.
Habituation/Familiarization: Repeating a stimulus until looking time decreases (less interest).
Test Events: Events used (after habituation) to see if infants understand a physical principle (possible vs impossible).
Looking Time: Amount of time an infant spends looking at a stimulus (a measure of attention and interest).
Perceptual Factors: Visual characteristics like novelty, complexity, movement, influencing looking time independently of understanding.
Rich Interpretation: The inclination to ascribe complex cognitive abilities (like reasoning) to infants based purely on looking time data.
Control Conditions: Ensuring similar perceptual features in possible and impossible events in VoE studies.
Manual Search Task: Infants physically searching for a hidden object, showing an understanding of object permanence.
Pupil Dilation: Widening pupils as a physiological response to stimuli (often surprise or interest).
Social Looking: Infants looking towards caregivers in response to unexpected/ambiguous events (seeking reassurance).

Number Concepts & Arithmetic

Analog-Magnitude Mechanism: Infants discriminate large quantities (over 4) based on differences in proportion (e.g., 8 vs. 16 easier to discriminate than 16 vs 24).
Object Tracking System: A system for visually tracking small numbers of objects (1-4), influenced by object complexity.
Habituation: Repeated stimulus presentation until response decreases, allowing identification of new stimuli.
Object Files: Theoretical concept portraying internal representations of single objects (color, size, location).
SNARC Effect: Faster responses to smaller numbers with left hand and large numbers with right (similar in infants).
Violation-of-Expectation (VoE) Paradigm: Used to study infant understanding of number.

Late Search & Graded Representations

Means-End Problem Solving: Infants execute multiple steps to achieve a goal.
Late Search: Infants, despite understanding object permanence, delay (until 8 months) in actively searching for hidden objects.
Intentional Search: Search characterized by purposefulness, removing obstacles to retrieve objects. (Before 8 months, actions with objects might indicate hidden-object understanding but not necessarily intentional retrieval).
Deficit/Interference Explanations: Possible reasons hindering infant search (e.g., inadequate motor skills, interference from visually guided reaching).
Interference from visually guided reaching: Reaching to the correct spot interferes with the ability to retrieve something hidden under it.
Inadequate Manual Skill: Infants lack adequate motor skills to find hidden objects.
Graded Representations: Infant object permanence, or understanding, develops gradually in strength (not instantly all-or-none).
Action Production vs. Action Perception: The ability to execute actions can be stronger than their understanding for infants.
