Chapter 10 - Motivation Flashcards
Define motivation (2)
the study of the factors that energize and simulate behavior
the driving force that lead us to pursue some things and avoid others, or to prioritize pursuing some goals and not others
What are the 4 essential components to motivational states?
- Energizing: the state needs to cause us to do something/expend energy
- Directive: a motivation has to be able guide behavior towards satisfying specific goals
- Persistence: a motivational state will persist until the goal is achieved
- Strength: the driving force of behavior; certain motivations get done over others because there is more strength behind
Is there an absolute distinction between biological and social motives?
No, motive can be both
What does eating have a lot to do with?
Learning (we learn to eat at certain times of the day and certain foods for those times)
What determines what (and when) we eat? (3)
Habits
Culture
Brain (hypothalamus: regulates eating responses)
What are the 3 hormones involved in eating? How do they all interact?
Insulin released when blood glucose levels rise (when eating sugar or carbs)
Leptin monitors fat deposits in the body, indicates to the brain that you should stop or start eating (reserves are full or low)
Ghrelin is a circulation hormone produced by cells; called the hunger hormone as it increases food intake (levels are highest just before meals when you’re hungry)
Don’t know how they all interact
Explain the relations between food and reward (3)
Good food that we like acts as a reward
In people who rely or indulge in food as a reward, there are difference in how they process rewards
Food that is sweet or salty is controlled by the limbic system (the main brain region involved in reward), the pre-frontal cortex specifically
What is obesity? (4)
The condition of being overweight
Body Mass Index exceeds 30
Canadian obesity rates hover around 20-21% and 40% overweight
Rates are increasing among adults and children
Why are obesity rates so high? (4)
Our environment today is much different than the environment long ago when food wasn’t as readily available
Our ancestors ate as much as they could because they didn’t know when they’d get their next meal
Today we still have that biological drive despite the fact that we have food (and food that is much worse for us than food was back then) almost always available to us
Also sitting much more than we used to and not nearly as active
What is unit bias? (3)
Tendency to assume that if someone puts a plate in front of you, that is the unit that you have to consume
Bigger proportions and plate sizes cause people to eat more as they eat their whole plate even if full
Shows connection between eating and cognition
What are three things that demonstrate connection between eating and the social context?
Social Facilitation: eating more because others encourage us to as a social welcome
Impression Management: eating less because we want to be seen in a positive light
Modelling: eating whatever they eat
Why is sex important? (3)
Tops the list of favorite human activities despite not being necessary to live
Important in many areas of daily life (marriage, family, aggression, competition, art, music, most creative pursuits)
Most animals have sex for reproduction (instead of cloning)
How does hormonal regulation determine desire? (4)
Hormones exert a lot of influence over sexual behavior
- Estrogens: female sex hormone
- Androgens: male sex hormone
Both present in both men and women but with more of one or the other as the principle hormone secreted by sexual organs
Sexual desire tends to fluctuate with level of testosterone
How do humans and animals differ in sexual motivation? (2)
Females in animal kingdom are most receptive to sexual activity during ovulation and you can see the higher level of secretion then
Unlike humans who feel sexual desire at any time
What are pheromones? (3) What are aphrodisiacs? (2)
The chemicals secreted by animals that are hypothesized to change behavior
Detected by a sense of smell
Research in humans is inconclusive (Axe)
A: Substances thought to increase sexual desire; little empirical support
