General adaptation syndrome
According to the general adaptation syndrome, the body's response to stress involves an alarm stage (initial flight-or-flight response), resistance stage (increased resistance to stress), and exhaustion stage (eventual decreased resistance to stress) that may lead to the development of mental and physical health issues.

Elaboration likelihood model
Elaboration likelihood model of persuasion proposes that when an individual is uninterested in a message, superficial factors (e.g. an attractive celebrity spokesperson) might be most persuasive. Therefore, the elaboration likelihood model is concerned with how nonverbal cues can influence the behavior of individuals; defines two routes of persuasion: the central route (focusing on the logical content of the message) is most effective when the audience is motivated by the message, whereas the peripheral route (focusing on superficial characteristics of the message) is more effective when people are not motivated by the same message

Kohlberg Moral development theory
Lawrence Kohlberg; proposes that humans progress through stages of moral and ethical reasoning throughout their lifetime, starting with basic moral reasoning during childhood and progressing to more abstract reasoning in adulthood. At the pre-conventional level, morality is externally controlled by punishment (stage 1) and reciprocity with others (stage 2). At the conventional level, morality is based on conforming to norms (stage 3) and obeying the law (stage 4). At the post-conventional level, which few people achieve, morality is based on a social contract (stage 5) and a personal code of ethics (stage 6)

Social loafing
Social loafing occurs when an individual expends less effort when working as part of a group than when working alone (e.g. people tend to clap less loudly as part of a group than when no one else is clapping)
Social networks
Social networks are informal, nonhierarchical webs of nodes (e.g. individuals) connected by ties, which can be weak (e.g. acquaintances) or strong (e.g. family). Social networks confer social capital through connections that can be converted into economic gain (e.g. new job), which can improve one's social statues, resulting in social mobility

Appraisal theory
States that one's evaluation of a stimulus determines one's emotional response. In a primary appraisal, an individual determines whether a stimulus is a threat, positive, or irrelevant. If it is deemed a threat, the individual evaluates whether their resources are sufficient to cope with the stressor in the secondary appraisal.

Differential association theory
Suggests that deviance is learned through interaction (i.e. someone goes to prison for drug possession and learns from incarcerated sellers how to efficiently sell drugs)

James-Lange Theory
The James-Lange theory suggests that specific emotions result from stimuli eliciting specific physiological reactions, which are transmitted to the brain via the spinal cord white matter (afferent axonal tracts, which carry sensory information from the body to the brain)
Malthusian theory of population growth

Spontaneous recovery
occurs when an extinct response reappears after a period of time
Avoidance learning
occurs when an individual figures out how to prevent experiencing the unpleasant stimulus in the future
Escape learning
occurs when an individual learns how to terminate a current unpleasant stimulus; escape learning becomes avoidance learning when an organism prevents coming into contact with an unpleasant stimulus
Stimulus discrimination
occurs when an organism distinguishes between two similar stimuli
Negative reinforcement
occurs when an undesirable stimulus is withdrawn, which encourages a behavior to happen again
Bystander effect

Foot-in-the-door phenomenon
predicts that people who are more likely to comply with a big request after they have already complied with a small request; this can be explained by a change in attitude: people tend to have more favorable attitudes toward those they have just helped, increasing the likelihood they will agree to the larger request

Mead theory of identity development
proposed that identity formation is the result of social interactions, particularly with significant others, early in life; -during the preparatory stage, babies/toddlers imitate others without comprehension of "self" -during the play stage, children begin understanding the perspectives of specific others (role-taking); when children understand themselves as individuals separate from others, the "I" component of the self has developed. Children then begin to imagine how others perceive them, which is the beginning of the development of the "me" -during the game stage, children understanding the perspective of others in society (generalized other) and social interaction rules
Maslow hierarchy of needs
proposes that basic needs (physiological and safety) must be met before psychological needs (love and belonging, esteem) can be attained.

Incentive theory
suggests behavior is primarily motivated by extrinsic (external) rewards, rather than internal rewards or biological drives
Incentive theory of motivation
suggests that individuals are motivated according to external rewards. Therefore, people engage in behavior that results in the most desirable outcomes. For example, people are motivated to go to work to make money
Trait theory
suggests that personality is the result of a combination of traits that are relatively stable over time; does not account for external influences on personality or for the reasons underlying personality traits
Spreading activation
suggests that when a node in the semantic network is activated, the nodes directly connected to the node are then activated as well (i.e. priming)
Strain theory
suggests that when individuals are unable to attain socially acceptable goals (e.g. having a nice car) through legitimate means (e.g. a job), the resulting strain may lead to deviant behavior (e.g. stealing)
Humanistic theory of motivation
suggests that, assuming more basic needs (like hunger) have been met, individuals are ultimately motivated to seek self-actualization, the ultimate fulfillment of their own potential. The motivation to pursue a medical degree is an example of wanting to fulfill one's potential.

Universalism
the belief that cognition controls language, posits that certain cognitive processes are universal, so all human languages also possess certain universals (e.g. noun)

glass ceiling
the mostly invisible barrier that keeps women from advancing to the top levels at work
Optic disc
the region of the retina where both the optic nerve (ganglion cell axons) exits the artery that vascularizes (supplies blood to) the retina enters. The optic disc is known a the "blind spot" because there are no photoreceptors in this area
opponent-process theory
the theory that opposing retinal processes (red-green, yellow-blue, white-black) enable color vision. For example, some cells are stimulated by green and inhibited by red; others are stimulated by red and inhibited by green
General fertility rate (GFR)
the total number of live births per year for every 1000 women of childbearing age in a population , which is a better measure of fertility than the CBR b/c it accounts for the age distribution and sex ratio of the population
