Maturation
Genes influence the environments people choose or experiences to which they’re exposed
Gene-environment correlations
The absence of normal input
Deprivation
Periods central to specific types of learning that modify future developmenta
Critical periods
Periods that are particularly important but not definitive for subsequent development
Sensitive periods
The ability to associate sensations of an object from different senses
Inter-modal understanding
Infants matching own actions to behaviours they have observed
Inter-modal processing
A phenomenon where people lack explicit memory for events before age 3 or 4
Infantile amnesia
The ability to retrieve memories despite changes in the cues that were present at encoding
Representational flexibility
Memories that can be consciously recalled
Explicit memories
Memory expressed in behaviour that may not be represented consciously
Implicit memory
____ memory involves information held briefly in consciousness
Working memory
What memory is the slowest developing memory system in development
Working memory
Cognitive adoption by interpreting actions or events in terms of one person’s schema
Assimilation
An organised, exercised pattern of thought or behaviour
Schema
Cognitive adaptive process of modification of schemas to fit reality
Accommodation
The driving forced behind cognitive developmet- balancing to adapt to the world
Equilibration
Stage where infants think with their hands, mouths and senses (0-2)
Sensorimotor stage
Infants learn about the world by mouthing, grasping, watching and manipulating objects
Sensorimotor stage
A major achievement of the sensorimotor stage
Object permanence
Recognition that objects exist in time and space independent of the child’s action
Object permanence
Cognitive stage which is characterised by the emergency of symbolic thought
Preoperational stage
Stage where children can play with the world in their minds and no longer have to think exclusively with their hands or mouths
Preoperational stage
The tendency to focus, centre on one perceptually striking feature of an object without considering other relevant information
Centration
