Chapter 10: Motivation and Emotion Flashcards
True or false, goals can be the result of both intentional and automatic activation?
true
What are motives?
the needs, wants, interests, and desires that send people in certain directions
What time was the Drive theory explored the most, and by who?
Clark Hull, in 1940s and 1950s
What do drive theories apply to behaviour?
applies homeostasis to behaviour
What is a drive?
an internal state of tension that motivates an organism to engage in activities that should reduce this tension
True or false, homeostasis is irrelevant to some human motives?
true! such as a thirst for knowledge
does motivation exist without drive arousal? ie. getting popcorn or ice cream after a movie because of an advertisment, not because you’re hungry
yes
What is the disadvantage to drive theories?
They cannot explain all motivation, such as motivation without drive
True or false, incentive theories propose that external stimuli regulate motivation
true
What is incentive?
an external goal that can motivate behaviour
True or false, drive theories emphasize how internal states of tension push people in certain directions
true
True or false, incentive theories emphasize how external stimuli pull people in certain directions
true
When speaking of drive theories, the source of motivation lies:
outside or within the individual?
within the individual
When speaking of incentive theories, does the source of motivation lie within our outside of the individual?
outside
Do incentive theories or drive theories operate according to the principle of homeostasis?
drive
What theory emphasizes environmental factors and downplays the biological bases of motivation
Incentive theory
According to expectancy-value models, ones motivation to pursue a particular course of action will depend on what two factors?
1– expectancy, about ones chances of obtaining the incentive
2– value, of desired incentive
What is the evolutionary theory of motivation?
explaining motives in terms of dominance, aggression, and sex drive in terms of their adaptive value..
What are the two agreed upon types of motives humans have?
biological and social
identify 3 biological motives and 3 social motives
biological: thirst, hunger, and sex
social: play, achievement, and autonomy (independence)
True or false, people have a limited number of biological needs
true
According to K.B Madsen, most theories identify 10-15 biological needs, but people can acquire social motives through what?
socialization and learning
What is Henry Murray associated with?
Social motives
When speaking of social motives associated with Henry Murray, what do the following motives mean?
Affiliation, nurturance, and exhibition
Affiliation: the need for social bonds
Nurturance: the need to care for others
Exhibition: the need to make an impression on others
Do social motives vary from person to person? If so, why?
yes, because off learning and socialization
What are the three motives that most psychologists study in detail?
hunger, sex, and achievement
What do evolutionary psychologists believe is behind motives?
products of evolution and natural selection
In 1912, Walter Cannon and Washburn studied hunger.. what did they find out?
there is an association between stomach contractions and hunger
What “controls” hunger?
hypothalamus
in the 1940s and 1950s, what brain structures did we believe controlled hunger?
Lateral Hypothalamus (LH) and Ventromedical Nucleus of the Hypothalamus (VMH)
What brain structures do we believe control hunger today?
2 parts of the hypothalamus:
Arcutate Nucleus and paraventricular nucleus
the arcutate is very important
True or False, Contemporary theories of hunger focus more on neural circuits that pass through the hypothalamus rather than anatomical centres in the brain
True
What is glucose and how is it made?
a simple sugar that is a source of energy, made by food taken into the body which is converted
Do actions that decrease blood glucose levels increase or decrease hunger?
increase hunger
What does the glucostatic theory propose?
that fluctuations in blood glucose level are monitored in the brain where they influence hunger feelings
What part of the thalamus is sensitive to glucose fluctuations that contribute to the modulation of eating?
The arcutate nucleus
Where is insulin secreted from, and what is it?
a hormone secreted by the pancreas
The more insulin secreted, the more what?
hunger feelings
What is ghrelin, and when is it secreted?
after going without food for a while, and it is a hormone secreted to create stomach contractions
What is CCK and when is it secreted?
It is secreted after food is consumed, it reduces hunger
What is leptin, and what does it do?
hormone, in charge of regulation of hunger and other bodily functions
How is leptin produced?
through fat cells.. Higher levels of fat= higher levels of leptin
true or false, the higher leptin in your blood stream, the less you feel hunger
true
Where do the hormones (insulin, ghrelin, CCK, and leptin) converge in the body? 1 brain structure, 2 exact spots
Hypothalamus, arcuate and paraventricular nuclei
True or false, hunger is regulated by environmental factors as well as biological
true
What are 3 environmental factors of hunger regulation?
1– availability of food
2– learned preferences/ habits
3– stress
If a psychologist believes that hunger is related to incentives, what 4 variables exert significant influence over food consumption?
1) palatability- better it tastes, more you eat
2) quantity available- more food avail, more you eat
3) variety- more variety, more you eat
4) presence of others- more people, more you eat
What is sensory-specific satiety?
as you eat a specific food, the incentive value declines.
think: only doritos and tortillas every day, they wouldn’t seem so appealing after a while
true or false, hunger and eating are governed in part by incentive qualities of food?
true
true or false, learning wields a great deal of influence over what people prefer to eat
true
true or false, taste preferences are partly a function of learned associations formed through classical conditioning
true
think: food poisoning bout, that food is paired with a crappy stimulus, therefore it was classically conditioned
True or false, eating habits are shaped by observational learning
true
think: seeing parents eat a food, you’re more likely to try it
true or false, people can have a genetic vulnerability to obesity
true
true or false, for overweight people, their energy intake from food exceeds their energy expenditure
True
Stanley Schachter created the “externality hypothesis” of obesity. Explain what it is..
obese people are extra sensitive to external cues that effect hunger and are insensitive to internal physiological cues
What was wrong with Schacter’s externality hypothesis according to researchers today?
it was oversimplified and overstated
true or false, today, we believe that external cues do have a greater impact on the food intake of obese individuals
True
Who made the distinction between normative and sensory external cues, and what are they?
Herman and Polivy.
Normative cues- socially appropriate food intake (what, when, how)
Sensory cues- palatability
What type of cues do Herman and Polivy argue that obese people are especially sensitive to?
Sensory external
Is the externality hypothesis relevant today?
yes
Who created the idea of a “set point?”
Richard Keesey
What is a set point?
A natural point of stability in body weight
What does the set point theory propose?
that the body monitors fat-cell levels to keep them (and weight) fairly stable
What is the settling point theory?
Weight tends to remain stable as long as there are no durable changes in any of the factors that influence it
Would hunger increase or decrease if the ventromedial nucleus of a rat’s brain is destroyed by lesioning?
increase
Would hunger increase or decrease if the glucose level in Marlene’s bloodstream decreases?
increase
Would hunger increase or decrease if Norman just ate, but his roommate just brought home pizza?
increase
Would hunger increase or decrease if you’re offered an exotic, strange-looking food from a different culture and told that everyone in that culture likes it?
most likely decrease
Would hunger increase or decrease if you are just given an injection of leptin?
decrease
Would hunger increase or decrease if you’re stressed?
most likely increase
Would hunger increase or decrease if you broke away from a diet?
increase
Which type of theory explains motives in terms of their adaptive value?
evolutionary or drive theories
evolutionary
Are lateral and ventromedial areas of the hypothalamus (on-off centres) or the Arcuate and paraventricular areas and neural circuits more important in todays theory of hunger?
Arcuate and paraventricular
Identify the 4 phases of the human sexual response and what happens during each
1) Excitement– physical arousal happens quickly, blood vessels swell
2) Plateau- slow arousal, tightening of vaginal entrance, preejaculate
3) Orgasm- Peak arousal intensity, muscle contractions
4) Resolution- refractory period, all changes subside
What is vasocongestion?
When blood vessels engorge
What happens during the excitement phase of the sexual response?
Vasocongestion and increased heart rate/respiratory rate
What happens during the plateau phase of the sexual response
Women continue to have vasocongestion which leads to tightening
Men may release pre-ejaculate
Fluctuations of arousal
What happens during the orgasm phase of sexual response?
increase in heart rate, increase in respiratory rate, muscle contraction
