Human Development Across the Life Span I
Developmental Psychology
o Interaction between physical and psychological processes

Are infants aware, individual, and active beings in their worlds or are they just a mass of
“blooming, buzzing confusion”?
o Clip #1: Are infants socially aware?
▪ Zoe interacting with her mother
▪ Stephan and “still-face” experiment
▪ Matthew hearing Mozart
o Clip #2: Are infants cognitively aware?
▪ Renee Baillaregeon’s work investigating infant’s sense of object

(a) Totally helpless and confused.
(b) Capable of making only a few simple responses.

Human Development Across the Life Span I
Cognitive Development
o Development of process of knowing: imagining, perceiving, reasoning, problem

What can babies remember?
o Long-term memory linked to brain frontal cortex development, which occurs at
about 12 months
o Taught babies to make toy at 9, 17, and 24 months, tested them again 4 months
later
Piaget’s Stages in Cognitive Development
o Sensorimotor stage
▪ 0-2 years old
▪ Object permanence, the beginning of symbolic thought
o Preoperational stage
