Four Major Themes
Thinking about biopsychologyConnecting the text to real life
Clinical implications The evolutionary perspective
The comparative approach – what can we learn from other species?
Cognitive neuroscienceConnecting brain activity and cognition

What is Biopsychology?
“the scientific study of the biology of behavior”
psychobiology, behavioral biology, behavioral neuroscience
psychology: the scientific study of behavior
Hebb (1949) proposed that psychological phenomena might be produced by brain activity
Copyright © 2006 by Allyn and Bacon
Biopsychology is an integrative discipline Knowledge from other disciplines of
neuroscience is applied to the study of behavior
Each discipline studies a different aspect of the nervous system that informs our understanding of what produces and controls behavior

Biopsychological Research
Human and nonhuman subjects
Experiments and nonexperiments
Pure and applied research
Copyright © 2006 by Allyn and Bacon
Human and nonhuman subjects
Differences are more quantitative than qualitative
Same basic structures (qualitative), but how much of each structure varies (quantitative)
Copyright © 2006 by Allyn and Bacon
Experiments and nonexperiments
Quasiexperimental studies – studies of groups of subjects exposed to conditions in the real world
Not real experiments as potential confounded variables have not been controlled
Copyright © 2006 by Allyn and Bacon
Pure and Applied Research
Pure research – conducted for the purpose of acquiring knowledge
Applied research – intended to bring about some direct benefit to humankind
Some research projects may have elements of both

Scientific Inference
The empirical method that biopsychologists use to study the unobservable
Scientists measure what they can observe and use these measures as a basis for inferring what they can’t observe
