Q

Q

maslows heirachy of needs

Q

signals to start a meal

A
  • liver converts stored nutrients into glucose
  • blood glucose levels are low
  • produce drop-rise pattern in glucose = changes in supply of glucose provide signals that help brain regulate hunger
  • lateral hypothalamus is active

Q

signals to end a meal

A
  • stomach and intestinal distention (swollen)

Q

what does leptin do?

A

Q

what are the psychological aspects of hunger?

A
  • eating is positively reinforced by good tastes and negatively reinforced by hunger reduction
    – expectations that eating will be pleasurable and will reduce hunger stimulate eating
    – beliefs, memories, and attitudes about food can also affect eating
  • pressure for thinness

Q

environmental factors affecting eating

A
  • food variety
    – smell and sight of food (classically conditioned)
    – presence of others

25
genetic influence on obesity
- influence basal metabolism - influence tendency to store energy as fat or lean tissue
26
anorexia nervosa
when individuals under-eat and have a distorted body image of being overweight → 1 in 300 young women in Canada
27
bulimia nervosa
when individuals binge and then engage in purging-type behaviour → 1 in 100 young women in Canada
28
sexual motivations
- desire to reproduce - obtain and give sensual pleasure - express love and intimacy - fulfill ‘duty’ - conform to peer pressure
29
four stages of sex
1.) Excitement = vasocongestion – blood flow increases to genitals 2.) Plateau = ncrease in vasocongestion, heart rate, respiration, muscle tension 3.) orgasm = rhythmic contractions 4.) resolution = genital organs return to normal, males enter refractory period, females may orgasm more
30
role of hypothalamus during sexual intercourse
hypothalamus controls pituitary gland = regulates secretions of gonadotropins = affect secretion of androgens and estrogens
31
what is functioning during the excitement phase?
- hypothalamus - amygdala - prefrontal cortex - striatum - ventral tegmental area
32
what is functioning duirng orgasm phase?
cerebellum and ventral tegmental area
33
what are the organizational effects of hormones?
- development of male/female sex characteristics - embryonic development - at about 8 weeks, development of testes = male; if not, female (the default gender)
34
what are the activational effects of hormones?
- sexual desire and behaviour (influence by androgens) - begin at puberty
35
different of sexual behaviour between men and women
- men reach orgasm more consistently than women - men have an increased desire for a variety of sexual partners - women have an increased desire for males with financial prospects
36
parental investment theory
suggests that differences in mate preferences are due to gender differences in parental investment
37
fantasy
Is a connection between mental processes and physiological functioning
38
desire
- sexual stimulus perceived positively - negative influences: stress, fatigue, anger, performance anxiet
39
effects of culture on sex
→ Culture shapes the expression of sexuality → Psychological meaning of sex depends on cultural contexts → Cultural norms affect sexual practices and techniques
40
environmental stimuli for sexual arousal
- touch, watching partner undress, erotic stories - pornography, sexual violence, attitudes
41
effects of pornography: social learning theory predictions
- learn through observation - coercion and domination are acceptable - viewers should become sexually aggressive
42
effects of pornography: catharsis learning theory predictions
- freudian concepts inborn aggression - viewing pornography provides ‘safe’ outlet - research does not support either theory
43
sexual orientation
→ A person’s preference for emotional and sexual relationships with a partner of the same or opposite sex → On a continuum = Heterosexual – bisexual – homosexual
44
why are people motivated to succeed?
- motive for success - fear of failure - situational factors - family influences - cultural influences
45
mastery goals
- intrinsic motivation - desire to master tasks and learn knowledge and skills
46
performance-approach goals
desire to be judged favorably compared to others
47
performance-avoidance goals
- desire to avoid negative judgments - fear of failure and performance avoidance goals impairs performance
48
traits of high need achievers
- ambitious - persist longer at difficult task - perform best when conditions are challenging
49
what perceptions cause us to strive hard for success?
- responsible for outcome - risk of not succeeding - potential feedback
50
family influences on achievement and motivation
1.) causes high need for achievement →encourage and reward achievement = don't punish failure 2.) causes fear of failure →achievement taken for granted = failure is punished
51
why do people work?
- money - personal accomplishment - mastery and growth - satisfying interpersonal relationships
52
emotions
positive and negative feelings that involve a pattern of cognitive, physiological, and behavioural reactions to events
53
what is the link between motivation and emotion?
- react emotionally when goals and motives are gratified, threatened, or frustrated - strong reaction to important goals
54
features common to all emotions
1.) cognitive component → Subjective conscious experience 2.) physiological component → Bodily (autonomic) arousal 3.) Behavioural component → Characteristic overt expressions
55
adaptive value of negative emotions
narrow attention, increased psychological activation
56
adaptive value of positive emotions
broaden thinking, causes exploration and skill learning
57
cognitive component of emotion
- how the belief system, thinking, and knowledge affect one's emotions - interpretations and meanings attached to sensory stimuli
58
physiological component of emotion
- interactions between cortical and subcortical structures (hypothalamus, amygdala, hippocampus) - thalamus sends sensory input along two independent neural pathways (one directly to amygdala, one to cerebral cortex) - emotions accompanied by sympathetic autonomic nervous system (ANS) then by parasympathetic ANS activation
59
behavioural component of emotion
- expressive behaviours (observe and infer emotions of others)
60
what are the fundamental emotional patterns?
- expression of certain emotions is similar across variety of cultures - children blind from birth express basic emotions as sighted children do
61
James Lange theory of emotion
- somatic theory of emotion - body informs mind - physiological reactions determine emotions
62
Cannon-Bard theory of emotion
-cognition is invovled - stimuli to thalmus to cortex to emotion
63
schacter theory of emotion
- look to external cues to decide how we feel - physiological arousal = how strongly we feel - labeling what we feel
64
what is said about James Lange theory and people with spinal cord injuries?
- James-Lange says feedback from the body’s reactions to eliciting stimuli is critical to emotional experience - People with spinal cord injuries support idea that feedback from the body is NOT necessary for emotional experience
65
facial feedback hypothesis
- muscular feedback to the brain plays a key role in emotional experience - vascular theory of emotional feedback= tensing facial muscles alters temperature of blood flow (Cooling = positive affect, Warm = negative affect)
