Lecture 3C Flashcards
Process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events
Perception
All mental activities associated with thinking, knowing, remember and communicating
Cognition
What are the 3 fundamental processes of cognition?
Storing information, categorizing stored information, creating mental images of objects
Cognition develops through a series of qualitatively distinct stages
Piagetian Theory
Mental abilities (adding, subtracting, categorizing, mental rotation, separating, organize things mentally, combining, reversing)
Mental operations
Giving meaning to objects, allows infants to categorize objects
Scheme
Basic sucking, grasping, rooting, looking are reflexive in nature, infants driven to employ schemes, purely perceptive
Reflex stage
When is the reflex stage?
0-1 months
1st acquired adaptation initial responses are chance then repeated by the infant; focused on self indent external world, scheme not purely reflexive
Primary circular reactions
When is the primary circular reactions phase?
1-4 months
Involves baby with an object or another person, acting to reproduce effect, making interesting sights last, greater interest in environmental consequence of action
Secondary circular reactions
When is the secondary circular reactions phase?
4-8 months
Start applying multiple schemes to same object, start applying one scheme in service to another, actions are goal directed
Coordination of secondary schemes
When is the coordination of secondary schemes?
8-12 months
Take independent and varied actions to people actively discover the properties of people and objects, new means through active experimentation establish cognitive structures
Tertiary circular reactions
When is the tertiary circular reactions phase?
12-18 months
Establish representational abilities, form image of the world when not available to senses, mental trial and error
Final stage
When is final stage?
18-24 months
Knowing that objects exist as separate entities, independent of our actions and perception, recognition that self is an object among objects
Object concept/Permanence
More tuned into self, fail to demonstrate visual tracking
Stage 1 and 2
Beginnings of object concept, more tuned into objects, extending search for object along a trajectory, but if object is hidden, it doesn’t know it exists
Stage 3
Improved object concept, actively search for hidden objects, A not B error
Stage 4
Hide object in location A and B, but looks under A and won’t look under B even though they saw the person hide it under B
A not B error
More complete object concept, searching where object was last seen, but when journey to hiding place is not visible infant will fail to find object
Stage 5
True object concept, objects exist for infants as independent entities, exhaustively search, mentally represent objects and their displacement
Stage 6
How does an infant show true object concept?
Exhaustively searching
