Developmental Psychology:Branch of psychology which studies physical, cognitive
and social changes through the life span.
Issue Details
Nature/NurtureHow do genetic inheritance (our nature) and experience
(the nurture we receive) influence our behavior?
Continuity/StagesIs development a gradual, continuous process or a
sequence of separate stages?
Stability/ChangeDo our early personality traits persist through life, or do we become different persons as
we age.

Prenatal Development and the Newborn
How, over time, did we come to be who we are? From zygote to birth,
development progresses in an orderly, though fragile, sequence.

Infancy and ChildhoodInfancy and childhood span from birth to the teenage years. During
these years, the individual grows physically,
cognitively, and socially.
Stage Span
Infancy Newborn to toddler
Childhood Toddler to teenager

Infants & Habituation
• Infants look longer at novel stimulus
• Look less at familiar stimuli

Infancy & Childhood Physical Development
• You are born with the most brain cells you would ever have!
• Neural networks multiply as we grow & gain abilities
• Association areas for thinking, memory, and language are last areas to develop
• Maturation - gradual unfolding of genetically-programmed physical changes

Infancy & Childhood Motor Development
• Experience has little effect on motor development; it is mostly due to our genes & maturation

Maturation & Infant Memory
• Infantile amnesia– Conscious memory at age
3 ½ (Bauer, 2002)• As we develop language,
the way in which we organize memories change.
• A 5-year-old has a sense of self and an increased long-term memory, thus organization of memory is different from 3-4 years.
Infants do show evidence of some memory.
