Exam 3 Flashcards
The factors that direct and energize the behavior of humans and other organisms
motivation
Inborn patterns of behavior that are biologically determined rather than learned
instincts
The view that people and animals are born preprogrammed with sets of behaviors essential to their survival
instinct approaches to motivation
how is sexual behavior an instinct?
There is an innate biological instinct to reproduce
Theories suggesting that a lack of a basic biological requirement such as water produces a drive to obtain that requirement (in this case, the thirst drive)
drive-reduction approaches to motivation
Motivational tension, or arousal, that energizes behavior to fulfill a need
drive
what are some examples of basic drives?
- Hunger
- Thirst
- Sleep
- Sex
what is a primary drive?
fulfills a basic need
what is as secondary drive?
prior experiences and learning bring about needs

homeostasis
What functions operate via homeostasis?
needs for food, water, stable body temp, and sleep
The belief that we try to maintain certain levels of stimulation and activity, increasing or reducing them as necessary
arousal approaches to motivation
Theories suggesting that motivation stems from the desire to obtain valued external goals, or incentives
incentive approaches to motivation
Theories suggesting that motivation is a product of people’s thoughts and expectations—their cognitions
cognitive approaches to motivation
causes us to participate in an activity for our own enjoyment rather an for any concrete, tangible reward that it will bring us
Intrinsic Motivation
causes us to do something for money, grade, or some other concrete, tangible reward
extrinsic motivation
Who devised a model of motivation?

metabolism
this says that the presence of too many fat cells from earlier weight gain may result in the set point’s becoming stuck at a higher level than is desirable

Thematic Apperception Test (TAT)
An interest in establishing and maintaining relationships with other people
need for affiliation
A tendency to seek impact, control, or influence over others, and to be seen as a powerful individual
need for power
Feelings that generally have both physiological and cognitive elements and that influence behavior
emotions
basic emotions
happiness, fear, anger, sadness, and disgust
Who were the first researchers to explore the nature of emotions?
James and Lange
gut reaction to emotion
visceral experience
The belief that emotional experience is a reaction to bodily events occurring as a result of an external situation (“I feel sad because I am crying”)
James-Lange theory of emotion
The belief that both physiological arousal and emotional experience are produced simultaneously by the same nerve stimulus
Cannon-Bard theory of emotion
The belief that emotions are determined jointly by a nonspecific kind of physiological arousal and its interpretation, based on environmental cues
Schacter-Singer theory of emotion
Activation of a set of nerve impulses that make the face display the appropriate expression
facial-affect program
The hypothesis that facial expressions not only reflect emotional experience but also help determine how people experience and label emotions
facial-feedback hypothesis
positive emotions
love and joy
negative emotions
anger, sadness, fear, disgust
The branch of psychology that studies the patterns of growth and change that occur throughout life
developmental psychology
influence of parents, siblings, family, schooling, nutrition
environmental causes of behavior
causes based on an individuals genetic makeup that influences growth and development throughout life
hereditary causes
The issue of the degree to which environment and heredity influence behavior
nature-nurture issue
the unfolding of biologically predetermined patterns of behavior
maturation
Twins who are exactly the same genetically; allows us to see the importance of hereditary
identical twins

cross-sectional research
a group of people who grow up at similar times, in similar places, and in similar conditions
cohort
