The average human only uses 10% of their brain - FALSE
Our brains can never grow new cells/neurons – F ALSE
People are either left-brained (logical) or right-brained (creative) FALSE, some skills are
lateralized, but most of the times, both of the hemisphere are engaged in the function
Scientists aren’t sure why many antidepressants work – TRUE, there are unknown steps along
the way
Amnesia involves forgetting who you are RARELY, not everyone forgets everything,
especially your self knowledge, more often includes loss of memory
What is Biological Psychology?
Biological psychology, or behavioral neuroscience, is the study of biological bases of
psychological processes and behavior
Neuroscience is the study of the nervous system and related systems, and how those systems

How Do We Relate Brain and Behavior?
An independent variable is the factor that is being manipulated you interact with, ex:
looking at the effects of caffeine on people, two groups: one with coffee and other with
nothing, then your independent variable is coffee
A dependent variable is what is measured in response to changes in the independent
variable.
1) Somatic intervention—alteration of a structure or function to see how behavior is altered
– somatic means body, act on the the body to see a change behavior
2) Behavioral intervention—intervention in a behavior to see how structure or function is
altered change something in the environment to produce an affect in the body, ex: does
brain activity change when you see the face of an attractive person?
3) Correlation - measures how much a body measure varies with a behavioral measure (but
correlation does not imply causation) two variables vary together. Sometimes it’s the
only way to study something, ex: you cant assign people to have schizophrenia
Three Main Approaches to Studying Neuroscience of Behavior
Somatic Intervention - Rarely in humans because we use rats a lot hahah. A CAUSES B
