Study Guide: CHP 10 -- Motivation and Emotion Flashcards
- INSTINCT THEORY OF MOTIVATION?
–> “all organisms are born with INNATE BIOLOGICAL TENDENCIES that help them survive.” – all behavior is driven by instincts vs. learning…
- INCENTIVE THEORY?
- proposes that EXTERNAL STIMULI regulates MOTIVATION (e.g. ice cream, juicy steak, monetary prize, approval, A on exam…)
- PUSH(drive theory:homeostasis) vs. PULL THEORY(source of motivation lies OUTSIDE of organism, in the environment)
- STRESSES ENVIRONMENTAL factors and DOWNPLAYS BIOLOGICAL BASES of human motivation.
- role of HYPOTHALAMUS in hunger motivation?
- REGULATES HUNGER: LATERAL hypothalamus and VENTROMEDIAL nucleus are the brain’s on-off switches that control hunger
- ARCUATE NUCLEUS: contains group of neurons that is sensitive to incoming hunger signals
- note: its the NEURAL CIRCUITS that pass thru areas of the hypothalamus rather than the anatomical centers in the brain.
- role of GLUCOSE in hunger motivation?
- GLUCOSE is a simple sugar which circulates in the blood
- a decrease in BLOOD GLUCOSE level can INCREASE HUNGER and vice versa
- role of VAGUS NERVE in hunger motivation?
- is a CRANIAL NERVE
- when your stomach DISTENDS, the vagus nerve sends message to brainstem which tells it that you are full –> inhibits eating
- research has shown that a VAGOTOMY (cutting the vagus nerve) curbs the feeling of hunger
- role of INSULIN in hunger motivation?
- INSULIN: HORMONE secreted by the PANCREAS; causes cells in the LIVER, SKELETAL MUSCLES, and FAT TISSUE to absorb glucose from the blood. (not enough insulin causes DIABETES)
- ->insulin levels increase when people EAT
- role of LEPTIN in hunger motivation?
- produced by FAT CELLS thruout the body and released into BLOODSTREAM (higher levels of fat give off higher levels of leptin)
- provides info to hypothalamus about body’s fat stores
- hunger tends to diminish when leptin levels are high
- How do GENETIC FACTORS influence OBESITY?
- study: adults raised by foster parents compared w/ biological and foster parents w/ regards to BODY MASS INDEX –> found out that adoptees resembled BIOLOGICAL PARENTS much more than adoptive parents; + twin study (identical vs. fraternal)
- conclusion: genetic factors account for 61% of variation of weight in MEN; and 73% women; some people can inherit a GENETIC VULNERABILITY to obesity
- How does SET POINT influence OBESITY?
= NATURAL POINT of STABILITY in body WEIGHT;
ppl who have a genetic predisposition towards obesity will have a hard time losing the weight, because according to the set point theory, there will be a strong tendency for them to gain back the weight they lost
- How does PARENTAL INVESTMENT THEORY influence SEXUAL BEHAVIOR?
- PARENTAL INVESTMENT: what each sex has to invest: in terms of time, energy, survival risk… to nurture offspring.
- -> male: make SMALLER INVESTMENTS so pursue mating opportunities more VIGOROUSLY; OVERESTIMATE women’s sexual interest in them;
- ->female: make BIGGER INVESTMENTS, so more CONSERVATIVE and SELECTIVE;
- What FACTORS (often unconsciously) influence MATE PREFERENCES? How can these preferences be explained?
- more emphasis on YOUTHFULNESS, ATTRACTIVENESS (will they have healthy children?)
- more emphasis on INTELLIGENCE, AMBITION, INCOME, SOCIAL STATUS…(can they provide??)
- can be explained with PARENTAL INVESTMENT THEORY
- How is SEXUAL ORIENTATION explained?
- END POINTS on a CONTINUUM? devised a seven point scale (completely heterosexual –> completely gay)
- still haven’t found biological basis for homosexuality; twins studies suggest there IS a genetic predisposition towards homosexuality–>abnormalities in prenatal hormones during neurological development
- Describe characteristics of individuals with HIGH ACHIEVEMENT ORIENTATION. (5)
- tend to work HARDER and more PERSISTENTLY on tasks
- handle NEGATIVE FEEDBACK more effectively
- more FUTURE-ORIENTED–>more likely to DELAY GRATIFICATION in pursuit of LONG-TERM GOALS
- HIGH CORRELATION b/w high achievement and EDUCATIONAL ATTAINMENT–>go into competitive, entrepreneurial occupations
- tend to select TASKS of INTERMEDIATE DIFFICULTY(want a moderate degree of challenge)
- Identify ATKINSON’s SITUATIONAL DETERMINANTS of ACHIEVEMENT BEHAVIOR. (4)
SITUATIONAL DETERMINANT: vary from one situation to another
- the amount of MOTIVATION TO ACHIEVE SUCCESS
- the PROBABILITY OF SUCCESS
- the INCENTIVE VALUE OF SUCCESS(how big is the personal reward?)
- EMOTION(e.g. anger, jealousy…) can lead to motivation and vice versa (e.g. fail at an exam you studied very hard for…)
- How to GENETIC FACTORS, FAMILY ENVIRONMENT, and CULTURE influence ACHIEVEMENT MOTIVATION?
GENETIC factors:
- AUTONOMIC NS (depends on genetics –> more sensitive, less sensitive…)
- REWARD PATHWAYS (ppl who have more myelinization and stronger connections..more motivated to achieve because more rewarding…)
FAMILY environment: supportive parents
CULTURE:
- some cultures VALUE ACHIEVEMENT more than others..
- what do we DEFINE as achievement? helps the group(what’s going to meet my family needs)? helps the individual?
