Basic Theoretical Issues Issue 1: Which is More Important—Heredity or Environment?TRANSCRIPT
Guideposts for Study 1. What purposes do theories
serve? 2. What are three basic theoretical
issues on which developmental scientists differ?
______________: Coherent set of logically related concepts that seeks to organize, explain, and predict data.
________________________: Possible explanations for phenomena, used to predict the outcome of research.
Basic Theoretical Issues Issue 1: Which is More
Important—Heredity or Environment?
_________________/Nature: Inborn traits and characteristics inherited from the biological parents.
Environment/______: influences, both before and after birth, including influences of family, peers, schools, neighborhoods, society and culture.
Research points to a blend of inheritance and experience
Basic Theoretical Issues Issue 2: Are Children Active or
Passive in their Development? 1. _____________ Model: people are
like machines that react to environmental input
2. _____________ Model : people are active, growing organisms that set their own development in motion
1. Mechanistic Model _______: children are a clean slate,
tabula rasa, upon which society writes
People are like machines that react to environmental input
Prediction of human behavior based upon __________ and _________forces at work
2. Organismic Model _______________: Children are “noble
savages” who would develop according to positive natural tendencies unless corrupted by a repressive society
Children are _________, growing, changing organisms
People initiate events, not simply react to them
Human behavior is a complex _______ unit; it cannot be broken down into small parts
Basic Theoretical Issues
Issue 3: Is Development Continuous, or Does It Occur in Stages?
Continuous: Mechanistic Approach Change is quantitative, increasing in
__________ rather than changes in quality or type
Change in the frequency with which a response is made, rather than changes in the __________of response
Learning Theorists, e.g., Watson and Skinner
Stages: Organismic Approach Change is qualitative, occurring in a
series of _____________ stages At each stage people cope with
different kinds of problems and develop different kinds of ______________
Each stage builds on the previous one and prepares the way for the next
Is development continuous, or does it
occur in stages?
Basic Theoretical Issues An Emerging Consensus
Developmentalists are coming to a more balanced view of active versus passive development
Influence is ___________________: children change their world even as it changes them
Example: a baby girl born with a cheerful disposition is likely to get positive responses from adults, which strengthens her trust that her smiles will be rewarded and motivates her to smile more
