| Question | Answer |
|---|---|
| Motivation | The biological, emotional, cognitive, or social forces that activate and direct behavior. |
| Instinct Theories | The view that certain human behaviors are innate and due to evolutionary programming. |
| Drive Theories | The view that behavior is motivated by the desire to reduce internal tension caused by unmet biological needs. |
| Homeostasis | The idea that the body monitors and maintains internal states, such as body temperature and energy supplies, at relatively consistent levels; in general, the tendency to reach or maintain equilibrium. |
| Drive | A need or internal motivational state that activates behavior to reduce the need and restore homeostasis. |
| Incentive Theories | The view that behavior is motivated by the pull of external goals, such as rewards. |
| Arousal Theory | The view that people are motivated to maintain a level of arousal that is optimal – neither too high nor too low. |
| Sensation Seeking | The degree to which an individual is motivated to experience high levels of sensory and physical arousal associated with varied and novel activites. |
| Humanistic Theories of Motivation | The view that emphasizes the importance of psychological and cognitive factors in motivation, especially the notion that people are motivated to realize their personal potential. |
| Glucose | Simple sugar that provides energy and is primarily produced by the conversion of carbohydrates and fats; commonly called blood sugar. |
| Insulin | Hormone produced by the pancreas that regulates blood levels of glucose and signals the hypothalamus, regulating hunger and eating behavior. |
| Basal Metabolic Rate | When Body is at rest, the rate at which it uses energy for vital functions, such as heartbeat and respiration. |
| Adipose Tissue | Body fat that is the main source of stored, or reserve, energy. |
| Energy Homeostasis | The long-term matching of food intake to energy expenditure. |
| Ghrelin | Hormone manufacture primarily by the stomach that stimulates appetite and the secretion of growth hormone by the pituitary gland. |
| Positive Incentive Value | In eating behavior, the anticipated pleasure of consuming a particular food; in general, the expectation of pleasure or satisfaction in performing a particular behavior. |
| Satiation | In eating behavior, the feeling of fullness and diminished desire to eat that accompanies eating a meal; in general, the sensation of having an appetite or desire fully or excessively satisfied. |
| Cholecystokinin | Hormone secreted primarily in the small intestine that promotes satiation; also found in the brain. |
| Sensory-Specific Satiety | The reduced desire to consume a particular food. |
| Leptin | Hormone produced by fat cells that signals the hypothalamus, regulating hunger and eating behavior. |
| Neuropeptide Y | Neurotransmitter found in several brain areas, most notably the hypothalamus that stimulates eating behavior and reduces metabolism, promoting positive energy balance and weight gain. |
| Set-Point Theory | Theory that proposes that humans and other animals have a natural or optimal body weight, called the Set-Point Weight, that the body defends from becoming higher or lower by regulating feeling of hunger and body metabolism. |
| Setting-Point models of Weight Regulation | General model of weigh regulation suggesting that body weight settles, or stabilizes, around the point at which there is balance between the factors influencing energy intake and expenditure. |
| Body Mass Index | A numerical scale indicating adult height in regulation to weight, calculated as (703 x weight in pounds)(height in inches). |
| Obese | Condition characterized by excessive body fat and a body mass index equal to or greater than 30.0. |
| Cafeteria Diet Effect | The tendency to eat more when a wide variety of palatable food is available. |
| Leptin Resistance | A condition in which higher-than-normal blood levels of the hormone leptin do not produce the physiological response. |
| Weight Cycling | Repeated cycles of dieting, weight loss, and weight regain; also called yo-yo dieting. |
| Eating Disorder | A category of mental disorders characterized by severe disturbances in eating behavior. |
| Anorexia Nervosa | An eating disorder characterized by excessive weight loss, an irrational fear of gaining weight, and distorted body self-perception. |
| Bulimia Nervosa | An eating disorder characterized by binges of extreme overeating followed by self induced vomiting, misuse of laxatives, or other inappropriate methods to purge the excessive food and prevent weight gain. |
| Hierarchy of Needs | Maslow’s hierarchical division of motivation into levels that progress from basic physical needs to psychological needs to self-fulfillment needs. |
| Self-Actualization | Defined by Maslow as a person’s “full use and exploitation of talents, capacities, and potentialities”. |
| Self-Determination Theory | Edward Deci and Richard Ryan’s theory that optimal human functioning can occur only if the physical needs for autonomy, competence, and relatedness are satisfied. |
| Intrinsic Motivation | The desire to engage in tasks that the person finds inherently satisfying and enjoyable, novel, or optimally challenging; the desire to do something just for its own sake. |
| Extrinsic Motivation | External factors or influences on behavior, such as rewards, consequences or social expectations. |
| Competence Motivation | The desire to direct one’s behavior toward demonstrating competence and exercising control in a situation. |
| Achievement Motivation | The desire to direct one’s behavior toward excelling, succeeding, or outperforming others at some task. |
| Thematic Apperception Test | A projective test developed by Henry Murray and his colleagues that involves creating stories about ambiguous scenes that can be interpreted in a variety of ways. |
| Emotion | A complex psychological state that involves subjective experience, a physiological response, and a behavioral or expressive response. |
| Emotional Intelligence | The capacity to understand and manage your own emotional experiences and to perceive, comprehend, and respond appropriately to the emotional responses of others. |
| Basic Emotions | The most fundamental set of emotion categories, which are biologically innate, evolutionarily determined, and culturally universal. |
| Interpersonal Engagement | Emotion dimension reflecting the degree to which emotions involve a relationship with another person or other people. |
| Amygdala | Almond-shape cluster of neurons in the brain’s temporal lobe, involved in memory and emotional responses, especially fear. |
| Brain Fingerprinting | Technique use to detect lies or deception, which uses an electroencephalograph to analyze brain waves; determines whether a stimulus is familiar ( i.e. recognized because it is stored in the suspect’s memory) or unfamiliar. |
| Display Rules | Social and cultural regulations governing emotional expression, especially facial expressions. |
| Anthropomorphism | The attribution of human traits, motives, emotions, or behaviors to nonhuman animals or inanimate objects. |
| James-Lange Theory of Emotion | The theory that emotions arise from the perception of body changes. |
| Facial Feedback Hypothesis | The view that expressing a specific emotion, especially facially, causes the subjective experience of that emotion. |
| Two-Factor Theory of Emotion | Schachter and Singer’s theory that emotion is the interaction of physiological arousal and the cognitive label that we apply to explain the arousal. |
| Cognitive-Meditational Theory of Emotion | Lazarus’s theory that emotions result from the cognitive appraisal of a situation’s effect on personal well-being. |
| Self-Efficacy | The degree to which a person is convinced of his or her ability to effectively meet the demand of a particular situation. |
