Chapter 4- Developmental Psych Flashcards
developmental psychology
changes in biological, physical, psychological, and behavioural processes
critical period
age where experiences must occur to develop normally
sensitive periods
optimal age range to learn something
cross sectional research
compares different ages at the same time
longitudinal research design
test same cohort at different times
sequential research design
combination of cross sectional and longitudinal design
germinal stage
-first 2 weeks after conception
-zygote attatches to uterine wall
embryonic stage
-2nd-8th week
-placenta and umbiical cord develops
-organs and system begins to develop
fetal stage
-begins at 9th week
-28 weeks=age of viability
Y chromosomes contains ______ and the critical period is 6-8 weeks
TDF
teratogens
environmental agents that may cause abnormal fetal development
fetal alcohol spectrum disorders
cognitive, behvaioural, and physical deficits and developmental abnormalities caused by prenature exposure to alcohol
William James (1890) suggested that the newborn’s world and mind are
passive, disorganized and have an empty mind
-view is no longer valid
how do we know what newborns can see
preferential looking prcedure
-measures how long an infant looks at a stimulus
preferential looking procedure
measure how long infant looks at a stimulus and determine when detail becomes interesting
newborns can see a range of colours by ____ months and prefer _____ stimuli
three;patterned
newborns orient to ______
significant stimuli
sound localization
ability to localize sounds
-disapears at 4 months and reappears at 6 months
phoneme discrimination
ability to detect changes in speech sounds
-disappears by 1 year of age
music perception
-shows similar responses of consonant and dissonant patterns as adults
-can remember short melodies
habituation procedure
based on the assumption that infants’ looking is influenced by novelty, and that infants look longer during test at novel items
imitation
newborns imitate adult facial expressions
cephalocaudal principle
development is from head to foot
proximodistal principle
development is from innermost to outer
stage like development
age of aquiring skill differs, but the sequence is the same
-some have U-shaped function
Piaget’s Stage theory
when an infant experiences an event or transitions from one stage to another
-brain build schemas
schema
a concept or framework that the child is using to understand a particular experience
