Chapter 3 pt 2 Flashcards
object permanence
the understanding that people and objects exist even when they cannot be seen
Piagets sensorimotor substages
0-1 month simple reflexes
1-4 months primary circular reactions
4-8 months secondary circular reactions
8-12 months coordination of secondary circular reactions
12-18 months tertiary circular reactions
18-24 months beginning of thought
Substage 1, simple reflex
infants interactions with the enviorment are determined by reflexes
0-1 months
-schemas for acting on an object derived from primary reflexes
-babies can accommodate changes into the reflexive behaviour
substage 2, primary circular reactions
1-4 months
infants coordinate simple repetitive actions around their own body
-seperate actions can be combined into one
-actions that are enjoyed are repeated
Substage 3, Secondary circular reactions
4-8 months
-infants repeat enjoyable activities through trial and error
-exert their actions on things outside of their body
-they don’t understand causality
-can imitate as long as they can see what they are doing
substage 4, ordination of secondary circular reactions
8-12 months
infants show goal directed behaviour and intentional reactions
-infants can combine two schemas to achieve a single goal
-they indicate some understanding of causality and anticipatory behaviour
-imitation is complete
Substage 5, tertiary circular reactions
12-18 months
-infants try variations of actions to explore consequences
-infants learn how to manipulate objects around them
-problem solving occurs through active exploration
substage 6, beginning of thought
18-24 months
-use mental symbols to represent objects or events
-can think about consequences of actions only by thinking
-mental representations can form
Infantile Amnesia
missing memory of what occurred before the age of 3
Explicit memory
-concious , recalled volentarially, Hioopcampus and cerebral cortex
Implicit Memory
-unconcious, recalled invollentariallm Cerebellum
Developmental quotient
overall development score that is based on performance in multiple domains
language characteristics
phonology: basic sounds that are combined to form sentences
morphemes: smallest meaningful piece of language
-semantics: rules governing language usage to form meaningful sentances
Precommunication
communication through non linguistic means
-babbling is making meaningless speech sounds emerging at around 2-3 months
Holophrases
one word utterances that represents entire phrases, have context specific meaning
