Influences on development

-drugs eg thalidomide
-smoking=low birth weight, behavioural issues
-alcohol=fetus alcohol syndrome


Birth complications

Pre-term and small for date:
-inc risk of infection, cognitive impairments
-problems for caregiving: can't hold, irritable, unresponsive
Interventions: incubator, stimulation, parent training


Motor development

enables: exploration of objects, surrounding, soc interactions
supports development of: social skills, cognition, language
Reflexes innate reveal health of nervous system, some have survival value eg moro reflex


Motor Skills

Fine: 3-4 months
Gross: 12 months
Maturational Theory (Gessell 1940)=mental and physical development in infants, children, and adolescents are comparable and parallel orderly processes.
Cephalocaudal trend= infants learning to use their upper limbs before their lower limbs.


Motor skills
Cultural variation

-Japan:walk before they crawl
-Jamaican babies walk earlier than N.American
-Zinacanteco Indians motor progress discouraged so development slightly delayed

*under or over stimulation= slower motor development


Perceptual Development of Newborn
Depth perception

=ability to judge distance between objects and from self which is necessary for reaching
Visual Cliff (Gibson & Walk 1960)


Perceptual Development of Newborn
Face recognition

newborns prefer face-like stimulation
track face like patterns more and look longer at attractive faces
prefer mother faces by 2 months
differentiate between strangers 3 months, emotions 7-10 months


Perceptual Development of Newborn
Gaze preference

Habituation=a decrease in response to a stimulus after repeated presentations.
Gaze preference
Habituation get them used to a picture, take it away give same picture of baby and another one of bold man
-idea that they've gotten bored of baby picture if they recognise the novel one


Perceptual Development of Newborn
Memory Development

Operate condition
reinforces certain behaviours
Baby mobile attached to foot, kicking makes mobile move
3 months-remembers for a week
6 months-remembers for two weeks
Memory highly context specific eg changing bumper interfered with baby's memory
