Q

Incentive

A

Something that “pulls” you towards a goal (ex. Good grades)

An environmental stimuli that pull an organism towarad a goal

Drug use is motivated by the positive incentive value of the drugs effect

EXPECTANCY THEORY
proposes that goal directed behaviour is jointly determined by two factors

  1. Strength of the persons expectation that particular behaviours will lead to the goal (Expectancy)
  2. The value the individual places on the goal (Incentive value)

Essentially EXPECTANCY x INCENTIVE VALUE = MOTIVATION

Q

Humanist Theory (Abraham Maslow)

A

Abraham Maslow believed that psychologies key motive is our strive for personal growth

He distinguished between DEFIENCY NEEDS (concerned w physical and social survival) and GROWTH NEEDS.

He proposed the concept of NEED HIEARCHY (Progression of needs containing defiency needs at the bottom and growth needs at the top)

Once our basic needs are met, we focus on safety and security

Then SELF-ACTUALIZATION represents the need to fulfill our potential

Q

Self-Determination Theory

A

A more recent humanistic theory

Focuses on three fundamental needs

COMPETENCE
(Reflects a human need to master new challenges and perfect skills.)

AUTONOMY
(Also self-determination, is satisfied when people experience their actions as a result of free choice without outside interference)

RELATEDNESS
(Refers to our desire to form meaningful bonds with others)

People are most fulfilled w their lives when they are able to satisfy these fundamental needs

Q

Hunger

A

Satiety: The feeling of being “Full”

Nutritionally rich food seem to produce more satiety more quickly than an equal volume of less nutritious food.

Patients who have had their stomachs removed still experience satiety not only because of intestinal distention, but also because of chemical signals.

The intestines respond to food by releasing PEPTIDES (help terminate a meal)

CCK (Cholecystokinin) is released into your bloodstream by the small intestine as food arrives from the stomach. It then travels to the brain and stimulates receptors in several regions that decrease eating

CCK decreases feelings of hunger

GHRELIN is released into the blood stream by the stomach and small intestine and is now thought to be one of the most important signals for hunger among humans

CCK = FULL

GHRELIN = HUNGRY

Lateral Hypothalamus is a “hunger on” centre

BEHAVIOURAL PERSPECTIVE

Eating is POSITIVELY REINFORCED by the good taste, and NEGATIVELY REINFORCED by hunger reduction

Q

Leptin

A

Fat cells are not storage cites for fat. They regulate food intake and weight by secreting LEPTIN

LEPTIN is a hormone that decreases appetite

As we gain fat, LEPTIN is secreted into the blood and reaches the brain.

LEPTIN does make us full like CCK, but it may regulate appetite by increasing potency of these other signals.

Q

Genes and Environment

A

Heredity influences our BASAL METABOLIC rate and tendency to store energy as either fat or lean tissue

More than 200 genes have been identified as possible contributors to human obesity

ENVIRONMENT

Q

Dieting and Weight Loss

A

Being fat primes people to stay fat

Obese people generally have higher levels of insulin (hormone from pancreas) than people with normal weight, which increases the conversion of GLUCOSE into FAT

Q

Masturbation

A

Men fantasize and masturbate about sex more often than women do

25% of men and 10% of women masturbate one or more times a week

60% of men and 40% of women masturbate ONCE a year

17
Q

Sexual Response Cycle

A

Masters and Johnson concluded that most people go through four-stage SEXUAL RESPONSE CYCLE when sexually aroused

During EXCITEMENT PHASE, arousal builds rapidly. Blood flows around the genital organs etc. (This is also called VASOGONGESTION)

In the PLATEU PHASE, respiration, heart rate, muscle tension continue to build until enough tension is there to trigger orgasm

During ORGASM PHASE, in males, rhythmic contractions of internal organs and muscle tissue surrounding the urethra project semen out of the penis. In females, orgasm involves rhythmic contractions of the outer third of the vagina.

In males, orgasm is followed by the RESOLUTION PHASE, physiological arousal decreases rapidly and the genital organs return to their normal condition

During the resolution phase, males inter the REFRACTORY PERIOD during which they are temporarily incapable of another orgasm.

Females can have two or more successive orgasms before the resolution phase

18
Q

Hormonal Influences

A

Same with hunger, the HYPOTHALAMUS plays a key role in sexual motivation

It controls the PITUITARY GLAND, which regulates the secretion of GONADOTROPHINS into the blood stream.

These effect the rate at which the GONADS (testes for male, and ovaries for females) secrete ANDROGENS (Testosterone, or estrogen)

Both men and women produce androgens and estrogens

In men and women, ANDROGENS (rather than estrogens), appear to have the primary influence on sexual desire

19
Q

Sexual Dysfunction

A

Refers to chronic, impaired sexual functioning that distresses a person

20
Q

Arousing Environmental Stimuli

A

A lovers caress can trigger sexual desire in an instant

Watching a partner undress

Both genders showed the strongest arousal when erotic stories focused on the female character, and when she was the one who initiated sex

21
Q

Pornography, Sexual Violence, Sexual Attitudes

A

Most porno users are men, but about a third of people who have purchased or rented porn are women

39% of women had at least one experience of some form of sexual assault

Most sexual assaults are NOT committed by strangers

According to SOCAL LEARNING THEORY, people learn through observation

Many pornos model “Rape Myths” (That men are entitled to sex when they want, and that women love to be dominated”

CATHARIS PRINCIPLE (freud and other psychoanalysts state that as inborn sexual and aggressive impluses build up, this tension provide a CATHARISIS that returns us to a more balances psyiological state)

Some countries w no porn have high rape rates, and vise versa

Such aggressive films seem to increase mens aggression towards women. (Violent porn)

Porn also promotes a view that sex is impersonal and decreases viewers satisfaction with their own sexual partners

22
Q

Sexual Orientation

A

Refers to one’s emotional and erotic preference for partners of a particular sex.

23
Q

Determinants of Sexual Orientation

A

No particular phenomenon of family life can be singled out, on the basis of our finding, as especially consequential for either homo-sexual or hetrosexual development… What we seem to have identified… is a pattern of feelings and reactions within the child that cannot be traced back to a single social or psychological root

Homosexuals are more likely to be tomboys during childhood

Those who had a gay brother, (52% were twins, 22% were fraternal twins, 11% were adoptive brothers)

The CLOSER the genetic relatedness, the higher the concordance rates for sexual orientation

The brain develops a neural pattern that predisposes organisms to prefer either male or female partners. Depending on whether prenatal sex hormone activity follows a masculin or feminine path.

Different personality styles drive people to different social experiences

Close relationships provide us with much more than the mere opportunity for sexual expression

24
Q

Need for Achievement

A

Which represents the desire to accomplish tasks and attain standards of excellence.

People strive for success using the feeling of sucess as motivation, or theyre motivated to avoid losing FEAR OF FAILURE

Anxiety makes it hard to process information, in sports this is an athlete who “Chokes” under pressure

25
Q

Achievement Goal Theory

A

Focuses on the manner in which success is defined both by the individual and within the achievement situation itself.

Mastery orientation: focuses on personal improvement, giving maximum effort, and perfecting new skills

Performance Orientation: in which the goal is to outperform others (With little effort as possible)

MASTERY APPROACH (master the task, learn, improve)

MASTERY AVOIDANCE (Avoid mistakes, poor quality)

PERFORMANCE APPROACH (Win, be the best, be noticed)

PERFORMANCE AVOIDANCE (Avoid losing, looking bad, being last)

26
Q

Motivational Conflict

A

APPROACH APPROACH CONFLICT
(Involves opposition between two attractive alternatives, selecting one means losing the other)
ex. Two good career paths

AVOIDANCE AVOIDANCE CONFLICT
(The opposite of approach-approach, when someone has to decide between two undesirable choices)
ex. Spend all week studying boring material, or skip studying and fail the exam?

APPROACH AVOIDANCE CONFLICT
(Involves being attracted to and repelled by the SAME goal)
ex. changing major to get better job, but also means another 5th year

DELAY DISCOUNTING
(The value of getting a good mark decreases the longer the delay)
27
Q

Emotions

A

Are positive or negative feelings consisting of a pattern of cognitive, phsiological, and behavioural reactions to events that have relevance to important goals or motives.

28
Q

The emotions we have share four common features

A

Emotions are responses to external or internal eliciting stimuli

Emotional responses result from our interpretation or COGNITIVE APPRAISAL of these stimuli, which gives the situation its perceived meaning and significance

Our bodies respond physiologically to our appraisal. We may become mad, scared, aroused etc.

Emotions include behaviour tendencies. Joy or crying, or ways of doing something about the stimulus, studying, running away.

29
Q

Evolution and Emotional Expression

A

Two key findings suggest that humans have innate or FUNDAMENTAL EMOTIONAL PATTERNS.

  1. The expressions of certain emotions (Rage and terror) are similar across cultures suggesting that its wired into the nervous system
  2. Children who are blind from birth seem to express these basic emotions in the same ways as sighted children do
30
Q

Cultural Display Rules

A

Display Rules: The norms for emotional expression within a given culture

31
Q

Instrumental Behaviours

A

Behaviours directed at achieving some goal

ex. a mother trying to find a nondestructive way to get her point across

32
Q

Theories of Emotion

A

THE JAMES-LANGE SOMATIC THEORY

The SOMATIC THEORY OF EMOTION: Proponents of this theory, body informs mind; our physiological reactions determine our emotions. We know we are afraid or in love ONLY because our bodily reactions tell us so.

THE CANNON-BARD THEORY

Cannon opposed the James-Lange theory and said that cognition must be involved as well

The theory concludes that when we encounter an emotion-arousing situation, the thalamus simultaneously sends info to the cerebral cortex AND the bodys internal organs.

The message to the cortex produces the experience of emotion, and the one to the internal organs produces the physiological arousal.

Neither causes the other, they are independent responses to the stimulation from the thalamus

Autonomic Feedback

Cannon tested on animals by severing the nerves on the organs to see if they responded to the dangers them selves. They did which supports his theory

33
Q

Facial Feedback Hypothesis

A

This feedback to the brain might play a key role in determining the nature and intensity of emotion that we experience

Research shows that positive or negative emotional responses can indeed be triggered by contraction of specific facial muscles (Supports Lang theory)

When participants hold a pencil between teeth, they feel happier. Compared to when they hold it with their lips

34
Q

Two-Factor Theory of Emotion

A

States that arousal and cognitive labelling based on situational cues are the critical ingredients in emotional experience
