unit 11: motivation and emotion Flashcards
motivation
a need or desire that energizes behavior and directs it to a goal
instinct theory
motivation is something that all organisms are born with
drive reduction theory
the goal of drive reduction theory is homeostasis: where all of your needs are met, but not over met
need vs. incentive
drives are your body’s way of motivating you (eating food because you are hungry)
while incentives are psychological ways your mind motivates you (eating because the food looks good)
homeostasis
balance/equilibrium/stability in the body
optimal/maximum arousal theory
organisms are motivated to have the most excitement possible
maslow’s hierarchy of needs
abraham maslow (1970) suggested that certain needs have priority over others
4 things that make you physiologically hungry
physiologically hunger means your body craves food naturally. these are 4 things that make your body crave food naturally.
- hunger pangs (stomach rumblings)
- low blood sugar (glucose)
- hypothalamus centers - lateral hypothalamus (LH) & ventomedial hypothalamus (VMH) - set-point theory
- hormones can also cause hunger
lateral hypothalamus (LH)
makes you hungry
ventromedial hypothalamus (VMH)
stops you from eating
set-point theory
theory that says that the lateral hypothalamus and the ventromedical hypothalamus work together to keep your hunger at homeostasis
psychological hunger
- means that your body isn’t naturally hungry, or full but your brain is regulating your eating behavior
- memory plays an important role in hunger
- where you live, and what culture you are from help determine how hungry you are, and what kinds of foods you crave and eat
anorexia nervosa
an eating disorder in which a normal-weight person continuously loses weight but still feels overweight
bulimia nervosa
an eating disorder characterization by episodes of overeating, usually high-calorie foods, followed by vomiting, using laxatives, fasting, or excessive exercise
obesity
a disorder characterized by being excessively overweight
it increases the risk of:
- cardiovascular diseases (breathing, heart issues)
- diabetes (body stop producing insulin)
- hypertension (high blood pressure)
- arthritis (joint pain)
- back problems
reasons for eating disorders
- childhood sexual abuse does not cause eating disorders
- younger generations develop eating disorders when raised in families in which weight is an excessive concern (nurture cause)
- twin studies show that eating disorders are more likely to occur in identical twins rather than fraternal twins (nature cause)
sexual motivation
nature’s clever way of making people procreate, enabling our species to survive
masters and johnson’s 4 stages of the sexual response cycle
refractory period
times after a male orgasm when another can not be achieved (sexual motivation decreases)
hormones and sexual motivation
both males and females have both sex hormones, but males have higher levels of testosterone and females have higher levels of estrogen
sexual orientation
refers to a person’s preference for emotional and sexual relationships with individual of the same sex (homosexuality), the other sex (heterosexuality), and/or either sex (bisexuality)
- homosexuality in men is 3-4% and in women is 1-2%
- research has been done on both potential nature and nurture influences, but current research point to nature being the more influential factor
- animal homosexuality: nature link: homosexuality exists in the animal world
- the brain: brain structure tends to look different in gay and straight men
- genes and sexual orientation: a number of reasons suggest that homosexuality may be due to genetic factors
- hormones and sexual orientation: prenatal hormones affect sexual orientation during critical periods of fetal development exposed to large amounts of testosterone more likely to be attracted to females. exposed to large amounts of estrogen more likely to be attraction to males
belongingness
- our need to be loved and accepted by others
- evolutionary psychologists believe that our need to be around others aided in our survival
- protecting aganist predoders, especially for the young
- finding food
- reproducing offspring
people who tend to have close friends are happier and healthier
