Unit 8 - Motivation, Emotion, and Stress Flashcards
motivation
a need or desire that energizes and directs behavior
instinct
a complex, unlearned behavior that is rigidly patterned throughout a species
4 perspectives for viewing motivational behavior
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
drive-reduction theory
idea that a physiological need creates an aroused tensions state that motivates an organism to satisfy the need
homeostasis
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
biological homeostasis
focuses on physical conditions such as hunger, thirst and temperature
cognitive 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
incentive
a positive or negative environmental stimulus that motivates behavior
Yerkes-Dodson theory
the principle that performance increases with arousal only up to a point, beyond which performance decreases
Myron Zuckerman
argues that people differ in the amount of stimulation they need or want
4 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
Maslow’s heirarchy of needs
self-actualization
esteem
love and belonging
safety needs
physiological needs
glucose
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
hypothalamus
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
insulin
hormone secreted by pancreas, controls blood glucose
Ghrelin
hormone secreted by empty stomach, sends the i’m hungry signal
Orexin
hunger-triggering hormone secreted by hypothalamus
leptin
protein hormone secreted by fat cells, when abundant, causes brain to increase metabolism to decrease hunger
PYY (peptide tyrosine tyrosine)
Digestive tract hormone, sens i’m not hungry signals to brain
Lateral hypothalamus (Large Hunger)
part of the brain that controls the desire to eat. When stimulated, eating does not cease.
