6 Psychology’s Current Perspectives
Focus Basic Idea Neuroscience How the body and brain enables emotions? If a behavior is not normal, there must be brain damage. Evolutionary How the natural selection of traits the promotes the perpetuation of one’s genes? Our behaviors are driven by the need to survive and/or reproduce. Behavior genetics How much our genes and our environments influence our individual differences? Our behaviors are largely controlled by our genetic inheritance.

Focus Basic Idea Psychodynamic How behavior springs from unconscious drives and conflicts? Behaviors are driven by suppressed traumatic experiences and emotions from our childhood. Behavioral How we learn observable responses? We behave in certain ways either to get a reward or to avoid a punishment.

8 Psychology’s Current Perspectives

We are either fall on the spectrum of optimism and pessimism. This perception is taught to us while young. Social-cultural How behavior and thinking vary across situations and cultures? Our behaviors are driven by the culture in which we live. Some behaviors are normal in one culture though inappropriate in another. (personal space, clothing, touching, gun ownership, etc.)
