Cross’s Nigrescence Model
In Cross’s Nigrescence Model, African-Americans are described as progressing through several stages of cultural awareness.
- Pre-encounter, African-Americans tend to view the majority Caucasian culture as being more desirable and would view a doctor of this race as being more skilled.
- Immersion-Emmersion: Someone in this stage would view the majority Caucasian culture with resentment and distrust and prefer to be treated by someone of his or her own race.
- Internalization Stage: integrated aspects of his own culture with that of the majority culture and is working to rectify past racial injustices.
Reconstructive Bias
a type of bias related to memory: we may not remember as accurately when under high amounts of stress
Social Desirability
a type of bias related to how people respond to research questions.
Selection Bias

Drive-Reduction Theory is correlated with what?
Arousal
Limbic System
regulates emotion and memory
Frontal Lobe
involved in humans’ ability to project future consequences of current actions
Schachter-Singer Theory

James-Lange Theory
behavioral and physiological aspects of emotion (like increased heart rate and shouting) lead to cognitive aspects of emotion (like understanding a situation is scary and feeling afraid).
Cannon-Bard Theory
physiological and cognitive aspects of emotion occur simultaneously and independently. Annabel’s brain released hormones at the same time that she interpreted the situation as happy and calm. The theory also states that behavioral expression is the last aspect - like when Annabel smiled.
Yerkes-Dodson Theory
people tend to perform their best when they’re moderately emotionally stimulated.
