MRI
Gives more detailed image of the brain
Axis V
Global assessment of functioning; global assessment of functioning scale (GAF) - yields score from 1 to 100, higher numbers are indicative of higher levels of functioning
Statistical Significance
How likely it is that an obtained result occurred by chance; The smaller the p-value, the more significant the results. P-value of 0.5 means a 5% chance exists that results occurred by chance
Validity

Psychoanalytic Perspective
Believe that the unconscious mind controls much of our thought and action. Says that we must examine our unconscious mind through dream analysis, word association, and other psychoanalytic therapy techniques. (Ex: says introverted person may limit social contact because of childhood trauma involving a social situation)
Humanist Perspective
Believe that we choose most of our behaviors and these choices are guided by physiological, emotional, or spiritual needs; the least deterministic model because behavior is not predetermined and rather comes out of free will. (Ex: says introverted person may limit social contact because they feel their social needs are better satisfied by contact with a few close friends rather than large groups)
Trait Perspective
Believe we can describe people's personalities by specifying their main characteristics, or traits; thought to be stable and to motivate behavior in keeping with the trait

Availability Heruistic
Estimating likelihood of events based on their availability in memory (if instances come readily to mind, we think such events are more common)
Cognitive Perspective
Examine human thought and behavior in terms of how we interpret, process, and remember environmental events. In this perspective, the rules that we use to view the world are important to understanding why we think and behave the way we do. (Ex: explains a person's tendency to be extroverted in terms of how he or she interprets social situations)
Longitudinal Study
Examines 1 group of participants over time (Ex: see how group of mentally challenged children progress in their learning skills)

Behavioral Perspective
Explain human thought and behavior in terms of conditioning. (Ex: says that person might be extroverted in terms of reward and punishment)
Biological Perspective

We might perform well at an easy task with a very high level of arousal, but the same high level of arousal would prevent us from performing well on a different task
Confirmation Bias
We tend to look for evidence that confirms our beliefs and ignore evidence that contradicts what we think is true; consequence is that we may miss evidence important to finding the correct solution
Approach-Approach Conflict
You must choose between 2 desirable outcomes (Ex: 1 friend invites you to go to the Galapagos and 1 friend invites you to go to Australia and both appeal to you but you must choose 1)
Avoidance-Avoidance Conflict
You must choose between 2 undesirable outcomes (Ex: You have a choice between staying home and cleaning the garage or going to your annoying cousin's house)
