Developmental Psychology Flashcards
father of developmental psychology
G. Stanley Hall
Arnold Gesell
nativist developmental psychologist; development is mostly biologically based and developmental blueprint exists from birth
What did Piaget think about developmental psychology?
children are actively involved in their own development
R. C. Tyron
tested rats on maze-running skills, divided into three groups based on skill level, bred them to create hyper maze bright rats and hyper maze dull rats
Lewis Terman
studied children with high IQs; large scale longitudinal study
phenylketonuria
genetic disorder resulting when enzyme needed to digest phenylalanine is lacking
Klinefelter’s syndrome
possession of an extra C chromosome in males; causes sterility and intellectual disability
Turner’s syndrome
only one X chromosome in females; failure to develop secondary sex characteristics
stages of prenatal development
zygote, germinal period (implantation), embyonic period (eight weeks after germinal), fetal (3rd month)
rooting reflex
infants turn when cheek is stroked
Moro reflex
infants react to abrupt movements of their head by flinging out their arms
Babinski reflex
infants’ toes automatically spread apart when the soles of their feet are stimulated
grasping reflex
infants automatically close their fingers around objects placed in their hands
What are some key ideas that Piaget came up with?
schemata, adaptation (assimilation and accommodation), four stages of cognitive development
schemata
organized patterns of behaviour and or thought. Infants develop behavioural schemata (action tendencies: and older children develop operational schemata (abstract representation of cognition)
assimilation
process of interpreting new information in terms of existing schemata
accommodation
occurs when new information doesn’t fit into existing schemata so existing schemata need to be modified to adapt to new information
stages of cognitive development in order
sensorimotor, preoperational, concrete operational, formal operational
sensorimotor
birth to 2 years old; primary and secondary circular reactions; no object permanence
preoperational
2 to 7 years; object permanence achieved; centration (focus on only one part of a phenomenon); egocentrism (no theory of mind); no conservation
