critical and sensitive periods
a maturational period where our brain is particularly sensitive to a certain type of information
continuity
gradual development from infant temperament into later personality
discontinuity
changes in infant mobility, like rolling over or walking
heredity
the genetic transmission of characteristics from parents to offspring
heritability
an estimate of the genetic proportion of the variation in some specific trait
schemas
mental framework that helps process how the world works
accommodation
The incorporation of new learning into an existing schema that requires revision of the schema
assimilation
The incorporation of new learning into an existing schema without the need to revise the schema
equilibration
The process by which a child engages in assimilation and accommodation in order to make sense of the world
sensorimotor stage
Jean Piaget’s stage of development beginning at birth and ending at the age of 2 years and characterized by active exploration of the environment
object permanence
ability to form mental representations of objects that are no longer present
circular reactions
repetitive actions observed in children during the sensorimotor stage of cognitive development
primary circular reaction
action on their own body
secondary circular reaction
interest in other objects (4-8 months)
tertiary circular reaction
goal-oriented (12 months)
preoperational stage
Jean Piaget’s stage of development beginning at the age of 2 years and ending at the age of 6 years and characterized by use of symbols, egocentrism, and limits on the ability to reason logically
longitudinal study
data from the same group of participants is collected at intervals across a long period of time (decades)
cross-sectional study
data is obtained simultaneously from participants of different ages in order to make age-related comparisons
egocentrism
Limitations on the ability to understand the point of view of other people
conservation
The ability to understand that changing the form or appearance of an object does not change its quantity
concrete operational stage
Jean Piaget’s stage of development beginning at the age of 6 years and ending at the age of 12 years and characterized by logical but not abstract reasoning
formal operational stage
Jean Piaget’s stage of development beginning at age 12 and extending through adulthood and characterized by mature reasoning capabilities
TOM (theory of mind)
the understanding that others have thoughts that are different from one’s own
false belief test
type of task used in theory of mind studies in which a child must infer that others don’t possess the same knowledge that they do
attachment
Emotional bond linking an infant to a parent or caregiver
secure attachment
A pattern of infant–caregiver bonding in which children explore confidently and return to the parent or caregiver for reassurance
Insecure-Resistant (anxious-ambivalent)
clings to caregiver, gets upset, both wants and resists comfort
Insecure-Avoidant (anxious-avoidant)
little distress when caregiver leaves, avoids the caregiver upon their return
authoritative
High parental support and high behavioural regulation
authoritarian
High behavioural regulation and low parental support
indulgent
Low behavioural regulation and high parental support
uninvolved
Low behavioural regulation and low parental support
Erikson’s psychosocial theory of development
every stage of identity features a developmental challenge that must be confronted in order to successfully progress. First lifespan theory of development
Erikson model: Birth
trust vs mistrust
Erikson model: Adolescence
identity vs role
Erikson model: Early adulthood
intimacy vs isolation
zone of proximal development
In Vygotsky’s theory, tasks that the child can accomplish with the assistance of more experienced or knowledgeable individuals
scaffolding
the process that enables a child to solve a problem, which would be beyond his unassisted efforts
preferential looking technique
spontaneous looking and listening behaviours towards visual and auditory stimuli
orienting reflex
occurs when someone is confronted with a personally significant stimulus
synaptic pruning
natural process of the brain eliminating extra synapses between early childhood and adulthood
Genie
victim of severe abuse, neglect and social isolation so she wasn’t able to acquire a language because she had not completed a first language before her critical period ended
research subject of language acquisition
Harry Harlow
attachement in Rhesus Monkeys
contradicts behaviourist perspective
Strange Situation test
semi-structured laboratory procedure that allows us to identify, without lengthy home observation, infants who effectively use a primary caregiver as a secure base
