Motivation & Emotion Flashcards
Motivation Theories/Concepts: Motives
Motives= needs, wants, desires, leading to goal-directed behavior
Motivation Theories/Concepts: Drive Theories
Drive Theories= seeking homeostasis; temperature changes or hunger/low energy
Motivation Theories/Concepts: Incentive Theories
Incentive Theories= regulation by external stimuli (trophies, money, etc)
Motivation Theories/Concepts: Evolutionary Theories
Evolutionary Theories= maximizing reproductive success (anything that allows us to survive and continue
Biological Factors of Motivation: general
originally thought was the size of the stomach, but even those with stomach removed due to conditions still got hungry
Biological Factors of Motivation: Brain Regulation
- lateral and ventromedial hypothalamus
- paraventricular nucleus
- arcuate nucleus
Biological Factors of Motivation: Glucose and Digestive Regulation
- glucose theory
- glucose monitored in the brain by glucostats (neurons sensitive to glucose)
Biological Factors of Motivation: Hormonal Regulation
- insulin (high levels increase hunger) and leptin (high levels and hunger diminishes)
Environmental Factors in Hunger: Learned preferences and Habits
- exposure
- when, as well as what
- who you eat with changes how much you eat
Environmental Factors in Hunger: Food-related cues
- appearance
- odor
- effort required
Environmental Factors in Hunger: Stress
link between heightened arousal/negative emotion and overreating
Eating and Weight- The roots of Obesity
- evolutionary explanations
- genetic predisposition (BMI and adoption study, twins studies suggest 61% variability)
- the concept of set point/settling point
- dietary restraint eaters (refrain often, think about it often. reduces inhibition like alcohol, then they eat and often binge)
- eating disorders
- sometimes when dieting, slip up, throw whole day out window since its “too late”, indulging with diet timing a factor
Evolutionary Motivation for Food
- evolved to avoid starvation (attracted to calorie rich foods, ability to store foods as fats)
- food high in saturated fats widely available (paradoxical effect of making the brain less sensitive to chemical messenger to stop eating
Motivation for Food
- gain weight (increase # and size of fats cells)
- lose weight (decrease size of fat cells only)
- more susceptible to gaining weight than losing
- dieting results in decrease in metabolism (each round of dieting= more efficient fat storing, more evidence for the idea of a natural set weight of body)
BMI and Twins
- identical twins whether raised together or not have same or similar BMI with a .7-.75 correlation
- fraternal twins whether raised together or not, have a low to moderate correlation
