1.01 Interaction of Heredity and Environment (Nature vs. Nuture)

Terms

Sensitive period/Critical period: the organism is most affected by outside factors in the environment (i.e. babies, toddlers)

• seen in Lorenz’s study of baby ducks who imprint on the first moving object they see

Temperament: our patterns and characteristic ways of responding to the environment; is genetically influenced

reciprocal determinism: the term that describes when a child’s temperament influences the parent’s behavior and in turn influences the development of the child’s personality (dual influence)

Identical: monozygotic (two zygotes separate when 14 wks)

fraternal: dizygotic (two zygotes)

Heritability: the genetic disposition of developing a behavior or trait, but it is not a predetermined outcome.

• having 2 tall parents but being malnourished as a child makes it more likely that you will not be tall, despite genetics
