Unit 7- Emotion, Motivation, Stress and Personality Flashcards
Motive
A need or a want that causes us to act.
Motivation
Motivation directs and maintains goal-directed behavior.
Motivation Theories
Explain the relationship between physiological changes and emotional experiences.
Instinct theory
Physical and mental instincts- Such as curiosity and fearfulness
cause us to act.
Instincts
inherited automatic species-specific behaviors.
Drive reduction theory
Drive - state of tension or arousal caused by biological/physiological needs. Unpleasant state that drives us.
Drive-reducing behaviors- we are motivated to engage in behaviors that reduce drives to maintain homeostasis.
Drive
State of tension or arousal caused by biological/physiological needs.
Drive Reducing Behaviors
We are motivated to engage in behaviors that reduce drives to maintain homeostasis.
Incentive theory
Motivation comes from incentives that give awarded outcomes or avoidance from punishment
Incentives can be positive or negative external stimuli that motivate and pull us toward a behavior
Arousal theory
People are motivated to take actions to increase or decrease arousal levels to achieve & maintain a personal optimum level of arousal. Each of us has an optimal level of arousal necessary to perform tasks which varies with the person and the activity. Arousal is the level of alert- ness, wakefulness, and activation caused by activity in the central nervous system. According to the Yerkes-Dodson law, for easy tasks, moderately high arousal is optimal; for difficult tasks, moderately low is optimal; and for most average tasks, a moderate level of arousal is optimal.
Maslow’s hierarchy of needs
Everyone wants to improve and reach self-actualization. Physiological motives are primary motives such as hunger, thirst, pain, and sex influenced by biological factors, environmental factors, and learned preferences and habits. Arranges biological and social needs in priority from the lowest level of (1) basic biological needs to (2) safety and security needs to (3) belongingness and love needs to (4) self-esteem needs to (5) self-actualization needs. The need for self-actualization, the need to fulfill one’s potential, and tran- scendence, spiritual fulfillment, are the highest needs and can only be realized after each succeeding need below has been fulfilled; lacks evidence to support theory.
Physiological motives
Primary motives such as hunger, thirst, pain, and sex are influenced by biological factors, environmental factors, and learned preferences and habits.
Hunger
Increases with stomach contractions, low blood sugar, high insulin levels that stimulate the lateral hypothalamus (LH); high levels of the neurotransmitters norepinephrine, GABA, and neuropeptide Y that stimulate the paraventricular hypothalamus (PVN); environmental factors such as the sight and smell of desired foods; and stress. Stimulation of the ventromedial hypothalamus (VMH) stops eating behavior.
Set Point
A preset natural body weight, is determined by the number of fat cells in our body.
Anorexia Nervosa
Eating disorders most common in adolescent females are characterized by a weight less than 85 percent of normal, abnormally restrictive food consumption, and an unrealistic body image.
Bulimia Nervosa
An eating disorder characterized by a pattern of eating binges involving intake of thousands of calories, followed by purging, either by vomiting or using laxatives.
Sex
Necessary for the survival of the species, but not the individual. Testosterone levels in humans seem related to sexual motivation in both sexes.
Thirst
Increases with mouth dryness; shrinking of cells from loss of water and low blood volume which stimulate the lateral hypothalamus; and sight and smell of desired fluids.
Pain
Promotes avoidance or escape behavior to eliminate causes of discomfort.
Sexuality Orientation
Refers to the direction of an individual’s sexual interest:
Homosexuality
A tendency to direct sexual desire toward another person of the
same sex.
Bisexuality
A tendency to direct sexual desire toward people of both sexes.
Heterosexuality
Tendency to direct sexual desire toward people of the opposite sex.
Social Motives
Learned needs, such as the need for achievement and the need for affiliation, energize behavior acquired as part of growing up in a particular society or culture.
Sexual Response
Sexual arousal, plateau, orgasm, and resolution.
Need for achievement
A desire to meet some internalized standard of excellence, related to productivity and success. People with a high need for achievement choose moderately challenging tasks to satisfy their needs.
Affiliation motive
The need to be with others; is aroused when people feel threatened, anxious, or celebratory.
Intrinsic motivation
A desire to perform an activity for its own sake.
