Development Across the Life Span
developmental theorists of the 20th century
Infants do not suddenly shift between stages of cognitive development. Instead Piaget argues that there is a transition period in which some behaviors reflect one stage, some the next stage (GRADUAL change!)
All children pass through a series of universal stages in a fixed order.
(we will elaborate on these more later…)
2) ACCOMMODATION is change in existing ways of thinking that occur in response to encounters with new stimuli or events.
Before object permanence develops, the infant will not search for an object.
1) Some developmentalists question the stage concept, thinking development is more continuous.
2) Piaget's notion that development is grounded in activity ignores the importance of infant's sensory and perceptual abilities.
3) Imitation and object permanence may occur earlier than Piaget suggested
4) Some development is universal, and some appears to be subject to cultural variations.
1) Encoding is the process by which information is initially recorded in a form usable to memory.
seek to identify the way that individuals take in, use, and store information
2) Storage refers to the maintenance of material saved in memory.
3) Retrieval is the process by which material in memory storage is located, brought into awareness, and used.
Information Processing Approaches to Cognitive Development
(affects encoding, storage, and retrieval of info!)
1) the DEVELOPMENTAL QUOTIENT
2) BAYLEY SCALES OF INFANT DEVELOPMENT
3) VISUAL-RECOGNITION MEMORY measurement
in intelligence during infancy, continued) BAYLEY SCALES OF INFANT DEVELOPMENTare a measure that evaluates an infant's development from 2 to 30 months.
mental and motor abilities…
(see table of sample items)
Information processing measures correlate moderately well with later measures of intelligence.
speech comprehension precedes speech production
Research shows that parents use different language for boys than for girls!
The use of diminutives declines with age, but women still hear them more consistently. What is the cultural significance of this?
(“kitty, dolly, birdie, dolly”)
Intriguing possibility that altering the language we direct at young women could change this!
~ Deaf mothers use a form of infant-directed speech too! Use slower tempo and repeat signs more often.
