Unit 8 (Motivation, Emotion, and Stress) Flashcards
a need or desire that energizes and directs behavior
motivation
a complex, unlearned behavior that is rigidly patterned throughout a species
instinct
Instinct theory - naturally predisposed behaviors
Drive reduction theory - how our inner drives and our external pulls interact
Arousal theory - focuses on finding the right level of stimulation
Abraham’s hierarchy of needs - discusses how some needs take precedence over others
4 perspectives for viewing motivational behavior
idea that a physiological need creates an aroused tensions state that motivates an organism to satisfy the need
drive-reduction theory
tendency to maintain a balanced or constant internal state; the regulation of any aspect of body chemistry, such as blood glucose, around a particular level
homeostasis
focuses on physical conditions such as hunger, thirst and temperature
biological homeostasis
involved mental conditions such as consistent, balance, and harmony in one’s thinking-that is seeking equity in the surrounding community, prioritizing one’s life, and promoting peace with the self and others
cognitive homeostasis
a positive or negative environmental stimulus that motivates behavior
incentive
the principle that performance increases with arousal only up to a point, beyond which performance decreases
Yerkes-Dodson theory
argues that people differ in the amount of stimulation they need or want
Myron Zuckerman
Four Forms of sensation seeking
Thrill and adventure seeking - people may seek excitement in risk but socially acceptable activities such as skydiving, racing
Experience seeking - this represents the desire to seek sensation through the mind, the senses, and nonconforming lifestyle
Disinhibition - those who have chose a middle class lifestyle but find it boring may seek escape in social drinking and partying
Boredom susceptibility - this occurs when people have a low tolerance for experiences that are repetitious or constant
the form of sugar that circulates in the blood and provides the major source of energy for body tissues. When the level is low, we feel hunger
Glucose
this neural traffic intersection includes areas that influence eating. For example, one neural arc, has a center that secretes appetite-stimulating hormones, and another center that secretes appetite-suppressing hormones
Hypothalamus
hormone secreted by pancreas, controls blood glucose
Insulin
hormone secreted by empty stomach, sends the i’m hungry signal
Ghrelin
hunger-triggering hormone secreted by hypothalamus
Orexin
protein hormone secreted by fat cells, when abundant, causes brain to increase metabolism to decrease hunger
Leptin
Digestive tract hormone, sends i’m not hungry signals to brain
PYY (peptide tyrosine tyrosine)
part of the brain that controls the desire to eat. When stimulated, eating does not cease.
Lateral hypothalamus (Large Hunger)
part of the brain that controls satiety. When stimulated, act as though you have already eaten.
Ventromedial hypothalamus (Very Minute Hunger)
the four stages of sexual responding described by Masters and Johnson - excitement, plateau, orgasm, and resolution
sexual response cycle
a resting period after orgasm, during which a man cannot acheive another orgasm
refractory period
a problem that consistently impairs sequal arousal or functioning
sexual dysfunction
sex hormones secreted in greater amounts by femailes than by males and contributing to female sex characteristics. In nonhumnan female mammals estrogen levels peak during ovulation, promoting sexual receptivity.
