What did Watson propose as the basic goals of scientific theory?
1. the mind cannot be observed
2. behavior can be observed
3. science should study the observable

What is reinforcement?
any consequence of a given behavior (think B.F. Skinner)
What is Humanistic psychology?
emerged in 1950s based on belief that people have positive values, free will, and deep inner creativity. inspired by the positive psychology movement (human behavior is completely out of human control)
Who created the idea of Humanistic psychology?
Carl Rogers and Abraham Maslow
What is cognitive psychology?
the approach in psychology that attempts to characterize the mental events that allow information to be stored and operated on internally
What is cognitive neuroscience?
the approach in pyschology thatt blends cognitive psychology and neuroscience (the study of the brain) when attempting to specify how the brain gives rise to mental processes that store and process information
What is evolutionary psychology?
evolutionarily successful cognitive strategies and goals survived, these strategies remain today because they serve an adapt function
What is cultural universality?
insistences of the same practice mental processes occurring in all cultures around the world
language, belief, values, norms, and behaviors shared among members of a group and passed from one generation to the next
