Test 3 Flashcards
What are Maslow’s hierarchy of needs?
- Physiological needs
- Safety needs
- belongingness and love needs
- esteem needs
- self actualization needs
What are the needs for physiological?
Hunger and thirst
What are the needs for safety?
Need to feel safe, secure, and stable.
What are the needs for belongingness and love?
Need to love and be loved, to be accepted.
What are the needs for esteem?
Need for self-esteem, achievement, competence, respect from others
What are the needs for self actualization?
Need to live up to one’s fullest and unique potential.
What is homeostasis?
Balanced internal state
What are the 3 factors of homeostasis?
- Temperature
- Blood glucose
- Water level
What does temperature do in homeostasis?
Cold = blood vessel constriction
What does blood glucose do in the process of homeostasis?
Triggers hunger
What does water level do in the process of homeostasis?
Triggers thirst
Met through drive reduction (arousal state that drives the organism to reduce the need)
Physiological needs
What affects our motivations?
- Internal state
- Incentives- external
- Our own learning history
- Health
- Culture
What are the mechanisms of hunger?
- Blood glucose levels
- Hypothalamus monitors through feedback from the stomach, intestines, liver, blood, etc
- Based on glucose levels, hyp signals hunger or satiety
Function of the lateral hypothalamus
Signals hunger
Destruction of the lateral hypothalamus is a result from…?
Lack of eating even if starving
Stimulation of the lateral hypothalamus can result to…?
Eating
Function of the ventromedial hypothalamus:
Signals safety
Stimulation of the ventromedial hypothalamus:
stop eating
Destruction of the ventromeidal hypothalamus:
Overeating even if full
Physiology of obesity:
- Fat cells
- Set point/metabolism
- Genetic
- Environmental
Fat cells:
Size and number
Set point/metabolism:
Basal metabolic rate (rate of energy expenditure at rest)
-diet actually decreases BMR
Environmental:
Family, mcdonalds, etc
What is intrinsic motivation?
Personal gain, enjoyment, competence, self-actualization, self-esteem
What is extrinsic motivation?
Grades, approval of others, rewards, money, deadlines
What is the main function of sexual motivation?
Hormones
What is the importance of hormones?

- Activate sexual behavior
a. Estrogen peaks at ovulation and female becomes receptive.
b. Male hormone levels more constant but loss of testosterone= loss of sexual behavior
c. Women’s sexual desire is only slightly higher at ovulation and women have sex throughout menstrual cycle
d. Sexual desire in women actually more closely related to testosterone levels
Human sexual motivation is influenced by:
- Physiology
- External Cues (environment)
- Imagination
The study of the evolution of the mind and behavior. How decisions and behaviors our ancestors made effect our own behavior.
-Based on principles of natural selection
Evolutionary Psychology
Why do men and women have different mating strategies?
Because the genders invest different amounts in the reproductive process.
Women strategy factors for the quality:
- Economic capacity: present or future
- Social Status
- Age: older than the female
Men factors for quatity:
- Youth
- Physical beauty
a. Body shape (waist to hip ratio, .70 most attractive)
b. symmetry - Healthy

400
On average, how much sperm do men produce per hour?
12 million per hour
An individual’s characteristic pattern of thinking, feeling, and acting.
