What are reflexes in a baby?
Grasping, rooting, sucking
Faces are special meaning?
Both behaviour and neural imaging studies provide evidence that face recognition early early in infancy (eg newborns prefer their mothers face over unfamiliar faces)
What are big questions in developmental psychology?

Universal or ecological, considering social or cultural influences on development
Continuous or discontinuous

Longitudinal designs and cross sectional designs
What are longitudinal designs?
Data from the same groups of individuals collects over intervals across a long period of time
What are cross sectional designs?
Data is obtained simultaneously from participates of different ages in order to make age related comparisons

Baby can recognize different types of lemurs but her older sister can’t
When does synapse formation occur? When is it highest?
Between 36 weeks and 2 years
Highest at 6 months
When does synapse pruning occur
Between 4 and 6 years
Where does the second period of overproduction occur
In the prefrontal cortex
When stage does overproduction occur before
Adolescentes
What happens after the second phase of overproductions
Ten years of pruning
How did bowlby describe the attachment theory
Strong emotional connection that persist overtime and across circumstances
What are benefits of the adaptive theory?
Adaptive-encourages proximity between mother and caregiver
Oxytocin
What did the results explain in Harry Harlows attachment in Rhesus monkeys?
Results contradicted behaviourist perspective and widespread societal implications
Research raised a lot of ethical questions
Mary Ainsworth’s “Strange Situaition” test outcome on secure attachment
Sixty five percent of children
Upset when caregiver leaves , easily comforted by their return
Mary Ainsworth’s “Strange Situaition” test outcome on insecure resistant
Clings to caregiver, get upset, both wants and resist comfort
