achievement

The realization of personal or professional goals; it embodies the desire to excel, surpassing others in various domains such as education, career, or sports. Achievement drives individuals to pursue excellence and recognition.

The connection and association with groups or individuals, which can enhance one’s social identity and provide emotional and psychological support. Affiliation often affects mental health and well-being.

anorexia nervosa

A severe eating disorder characterized by an obsessive fear of gaining weight, leading to self-imposed starvation and extreme weight loss. Individuals with anorexia often possess a distorted body image, viewing themselves as overweight even when dangerously underweight.

body mass index (BMI)

A metric that assesses body weight relative to height, calculated by dividing a person's weight in kilograms by the square of their height in meters. BMI categorizes individuals into classifications such as underweight, normal weight, overweight, and obese, serving as a general indicator of health.

bulimia nervosa

An eating disorder defined by recurrent episodes of binge eating followed by compensatory behaviors such as self-induced vomiting, misuse of laxatives, or excessive exercise. Individuals often experience feelings of shame, disgust, and loss of control surrounding their eating behaviors.

Cannon-Bard theory

A psychological theory suggesting that emotions and physiological reactions occur simultaneously but independently in response to an emotional stimulus, highlighting that awareness of emotions does not stem solely from physical sensations.

catharsis

The process of releasing and thereby providing relief from strong or repressed emotions. Catharsis was originally proposed as a theory of emotion suggesting that emotional expression can reduce psychological tension.

display rule

Cultural norms that dictate the appropriate expression of emotions in various social settings. Display rules can vary significantly between cultures, influencing how emotions are shown or concealed in public.

drive

A psychological and physiological state of arousal that prompts individuals to take action toward achieving a necessary goal or satisfying a basic need, such as hunger or thirst.

drive reduction

The relief experienced when a drive has been satisfied and the associated tension has been alleviated, often leading to feelings of reward and satisfaction after fulfilling a need.

emotion

A complex interplay of physiological arousal, physical sensations, and subjective feelings triggered by external stimuli, resulting in behavioral responses. Emotions can be positive or negative and vary in intensity.

extrinsic reward

A benefit or incentive that is provided by an external source, such as money, recognition, or awards, motivating behavior through outside reinforcement rather than intrinsic satisfaction.

glucose

A simple sugar that serves as a primary energy source for the body's cells and plays a crucial role in regulating hunger and energy levels. Fluctuations in glucose levels can trigger feelings of hunger.

homeostasis

The process by which biological systems maintain stability and equilibrium despite external changes, ensuring that critical physiological parameters such as temperature, pH, and energy levels remain within a certain range.

incentive

An external stimulus or reward that drives behavior by encouraging individuals to take specific actions, often perceived as desirable or beneficial outcomes.

insula

A region of the brain located at the junction of the frontal and temporal lobes, involved in sensory processing, emotional awareness, and the regulation of bodily states that contribute to subjective feelings.

intrinsic reward

A form of motivation that originates internally, where personal satisfaction or fulfillment drives behavior, rather than external rewards or recognition.

James-Lange theory

A psychological theory asserting that emotions occur as a result of physiological reactions to external events; that is, an individual feels an emotion after experiencing physical arousal.

leptin

A hormone produced by adipose (fat) cells that helps regulate energy balance by inhibiting hunger, thus contributing to the maintenance of body fat levels.

motivation

The internal processes that arouse, sustain, and guide behavior toward achieving specific goals or fulfilling needs, encompassing both intrinsic and extrinsic factors.

satiety

The feeling of fullness or satisfaction that occurs after eating, signaling the body to stop consuming food and helping regulate energy intake.

Schachter-Singer two-factor theory

A psychological theory stating that emotion is formed by two factors: physiological arousal and a cognitive label that interprets this arousal, leading to the subjective experience of emotion.

self-actualization

The realization or fulfillment of one’s talents, potential, and capabilities; it represents the pinnacle of psychological development as described in Maslow's hierarchy of needs.

set point

A theory suggesting that the body maintains its weight around a predetermined range or set point, regulating metabolism and hunger to achieve homeostasis.

sexual orientation

An enduring pattern of emotional, romantic, or sexual attraction to individuals of the same sex, opposite sex, or both; it includes aspects of identity and personal experience.

Somatovisceral Afference Model of Emotion (SAME)

A model that posits that a variety of physical sensations must be processed cognitively to bring about subjective feelings. It considers the range and specificity of physiological signals in forming emotional experiences.

testosterone

A steroid hormone predominantly produced in the testes in males, although also present in females; it influences a range of physical and behavioral traits, contributing to sexual development and motivation.

Yerkes-Dodson law

A principle that describes the relationship between arousal levels and performance, indicating that performance improves with arousal up to an optimal point but declines with excessive arousal.
