motivation
a need or desire that energizes and directs behavior
instinct
a complex, unlearned behavior that is rigidly patterned throughout a species
drive-reduction theory

two-factor theory
the Schachter-Singer theory that to experience emotion one must (1) be physically aroused and (2) cognitively label the arousal

the division of the autonomic nervous system that arouses the body, mobilizing its energy in stressful situations
parasympathetic nervous system
the division of the autonomic nervous system that calms the body, conserving its energy
appraisal theory
a theory of emotion that proposes that emotions are based on an individual's assessment of a situation or an outcome and its relevance to his or her goals (Lazarus)
mood
a temporary state of mind or feeling
facial feedback hypothesis
the tendency of facial muscle states to trigger corresponding feelings such as fear, anger, or happiness
display rules
culturally determined rules about which nonverbal behaviors are appropriate to display
microexpressions
small, brief facial movements that signal emotional experiences, even in people who have been trained to hide their emotions
universal emotions
happiness, sadness, surprise, fear, disgust, anger (HSSFDA)
most people can readily ID these emotions simply by observing facial expressions
primary emotions
emotions that are expressed by people in all cultures (ex. joy, anger, sadness, fear, and disgust)
