Chapter 11: Motivation and Emotion Flashcards
Motivation
The urge to move towards one’s goals
Needs
States of cellular or bodily deficiency that compel drives. These are what your body seeks like food, water, and oxygen
Drives
Perceived states of tension that occur when our bodies are deficient in some need. These deficiencies create a drive (thirst or hunger) to fix the state.
Incentive
An external object or event that motivates behavior such as money or winning a championship
So needs come from the body, incentive come from the environment
Examples of needs and drives?
Needs: Nutrients Drives: Hungry Needs: Water Drives: Thirsty Needs: Oxygen Drives: Suffocated Needs: Social Contact Drives: Lonely Needs: Pleasure Drives: Sex
Homeostasis
organisms work to maintain a Physiological balance around an optimal set point
set point
ideal fixed setting of a particular physiological system
For example like a thermostat in a room to make the temperature hot or colder to get it to room temperature, our bodies work the same way to get it to 98 degrees
Yekes-Dodson law
The principle that moderate levels of arousal lead to optimal performance
performance is worst when we are not very aroused (Asleep) or overly aroused (anxious)
Self-actualization
The inherent drive to realize one’s full potential
its one the top of the pyramid
What is the order from top to bottom of Hierarchy’s pyramid model?
Self-actualization Esteem needs Love and belonginess needs Safety and security needs Physiological needs
Metabolism
The rate at which we consume energy
What are the four biological components of hunger
Stomach, blood, brain, and hormones&neurochemicals
What is growling
Gastric secretions when we see food
What are stomach contractions?
Occur two hours after stomach and intestines have been relatively empty
Why does the stomach not necessarily cause hunger alone?
Some regions of the brain like the hypothalamus causes hunger psychologically. you could have ur stomach removed and still get hungry
glucose
simple sugar in the blood that provides energy for cells throughout the body
hypothalamus
triggers drive to eat when sugar levels drop
regulates psychological needs of hunger. acts as sensory detector, when body sends signals to hypo for nutrients need, hyp then signals to other parts of brain whether to start or stop eating
What four hormones simulate appetite?
Neuropeptide Y - released by hypo when animal is underfed or hungry
Ghrelin - sends signals to the brain for hunger, levels drop after eating
Orexin and Melanin - They are endocannabinoids. Natural chemicals that cause hunger. Sometimes blocked to help weight loss
What four hormones suppress appetite?
Insulin - Produced by pancreas, transports glucose, high sugar stimulates it
Leptin, Peptitde YY, and Chloecystokinin
Why do we eat WHAT we eat?
Influenced by external factors like culture, what you’re exposed to, even climate has an impact. People who live in Cold climates : eat raw animal fat. warm climates: spices
What is the motivation to be thin?
Food is abundant, always will be there. People live sedentary lifestyle compared to old days. Thin is more attractive, 70% girls between 14 and 21 say they’re on a diet. Obsession with thinness leads to eating disorders
Why could some people be obese?
It is 70% genetic. Adopted children lead towards natural parents body state than legal parents. Genes also control the number of fat cells a person has. Every year 10% of fat cells die, then 10% of fat cells are replaced
A gene that suppresses appetite, leptin, isn’t working properly
What is the evolutionary model?
purpose of organism is to survive and reproduce.
thru natural selection we want to survive.
three primary motivators are pleasure, pain, and reduction
