Title: Chapter 10: Motivation

Chapter 9Motivation and Emotion
2
Defining Motivation
  • Motivation involves goal-directed behavior
    (intentional, not random)
  • There are a number of different theories that
    attempt to explain goal-directed behavior.
  • Drive theories emphasize the importance of
    reducing physiological tension as a motivator of
    behavior (think we eat because we feel hungry)
  • Incentive theories emphasize the importance of
    external reward in motivation behaviors.
  • Evolutionary theories assert that human motives
    are products of evolutionary processes.

The Motivation of Hunger and Eating Biological
Factors
  • In the early 1900s, 1 (Full name) and Washburn
    hypothesized that there is an association between
    2 (2 words) and the experience of 3 However
    we know now that people who have their stomachs
    removed still experience hunger. This
    realization led to more complicated theories
    focusing on the brain, 4 (3 words) and
    digestive factors, and hormones.
  • Research in the 40s and 50s showed that the
    hypothalamus, particularly two areas called the
    5 (2 words) (LH) and the 6 (2 words) of the
    hypothalamus (VMH), are important in hunger. The
    LH was thought to be the 7 center, while the
    VMH was thought to control the ability to
    recognize 8 (fullness). Subsequent research
    indicated that the dual centered model was an
    oversimplified picture, although the LH and VMH
    are part of the hunger circuit, they are not the
    key elements.
  • The 9 nucleus of the hypothalamus has recently
    been implicated as another influential part of
    the hunger circuit.

The Motivation of Hunger and Eating Biological
Factors 2
  • Other research has focused on the role of blood
    glucose and digestive regulation on hunger.
    Manipulations that 10 when blood glucose level
    can 11 hunger (and vice versa).
  • 12 (name) theory proposed that fluctuations in
    blood glucose level are monitored in the brain by
    13 neurons sensitive to glucose in the
    surrounding fluid. It appears likely that hunger
    is regulated , in part, through glucostatic
    mechanisms.
  • Hormones circulating in the blood also appear to
    be related to hunger. Insulin, secreted by the
    pancreas, must be present for cells to use blood
    glucose. Normal secretion of insulin is
    associated with 14 hunger. The mere sight and
    15 of food has been shown to increase 16
    secretion.
  • Recently, a new hormone, 17 , has been
    discovered to be released from fat cells into the
    bloodstream. Leptin provides the hypothalamus
    with information about the bodys 18 stores in
    the body. When fat stores are high feeling of
    hunger diminish.

The Motivation of Hunger and Eating
Environmental Factors
  • Clearly, hunger is related to biology however,
    it is also regulated by environmental factors
    like (1) the availability/ palatability of food
    (2) 19 (2 words) habits and (3) stress.
  • Hunger can also be triggered by exposure to
    environmental cues that have been associated with
    20 .(such as appearance or odor of food, effort
    required to eat a particular food, etc).
    Research shows that these external cues influence
    eating behavior to some extent, beyond biological
    hunger.
  • Observational learning appears to play a part in
    what we like to eat. To a large degree food
    preferences are a matter of 21 . Studies show
    that people like foods that are familiar to them.
    (Even, dog meat is a delicacy in some parts of
    the world!) Learning also appears to influence
    when and how much people eat.
  • Finally, studies have show that 22 (arousal)
    leads to 23 eating with many people. Some
    research suggests that stress induced eating is
    especially common among 24 dieters.

The Human Sexual Response
  • William Masters and Virginia Johnson conducted
    groundbreaking research in the 1960s using 25
    recording devices to monitor the 26 changes of
    volunteers engaging in sexual activity. They
    outlined 27 () stages in the sexual response
    cycle.
  • The excitement phase is the initial arousal,
    which escalates rapidly. Muscle tension,
    respiration rate, heart rate and blood pressure
    28 quickly. Also 29 , the engorgement of blood
    vessels occurs in the genitals, occurs.
  • The plateau phase occurs when physiological
    arousal continues to build, but at a 30 pace.
  • The orgasm phase occurs when sexual arousal
    reaches its peak intensity and is discharged in a
    series of muscular contractions that pulsate
    through the 31 area. The subjective experience
    of orgasm is very similar for men and women,
    although women can more than 32 orgasm in a
    brief period of time. On the other hand, they are
    more likely to engage in intercourse without
    experiencing an orgasm.
  • The resolution phase is characterized by sexual
    arousal that gradually 33 . Men experience a
    refractory period after orgasm, when they are
    largely 34 to further stimulation. This may
    last from a few minutes to a few hours and 35
    with age.

The Mystery of Sexual Orientation
  • 36 (2 words) refers to a persons preference for
    emotional and sexual relationships with
    individuals of the same sex (homosexuality), the
    other sex (heterosexuality), or either sex
    (bisexuality).
  • Kinsey and others have concluded that
    homosexuality and heterosexuality are 37 (2
    words) on a continuum.
  • Data on the prevalence of homosexuality suggests
    that 38 ( range) of the population could
    reasonably characterized as homosexual.
  • Many environmental theories explaining
    homosexuality have been put forth historically.
  • Freud held that a person must identify with a
    strong same sexed parent or a homosexual
    orientation may develop.
  • 39 theorists assert that homosexuality is a
    learned preference acquired when same-sex stimuli
    hve been paired with sexual arousal (learned
    through conditioning.)
  • Extensive research have 40 to support either
    theory.
  • What has been found is that most men and women
    with homosexual orientations can trace their
    leanings back to early childhood, suggesting that
    the roots of homosexuality are more 41 than
    environmental.

Motivation
  • 42 motivation involves the need to excel,
    especially in competition with others. This
    motive involves the need to master _43_
    challenges and meet 44 standards of excellence.
  • People who are relatively high in the need for
    achievement work harder and more persistently,
    they tend to 45 gratification well and to
    pursue competitive careers.
  • Achievement (and affiliative) motivational needs
    are generally measured using the 46 (3 words), a
    projective test which requires a subject to write
    or tell stories about what is happening in
    pictures of people in ambiguous scenes.
  • 47 factors have been shown to influence
    achievement strivings, causing it to increase
    when the probability of success and the incentive
    value of success are high. When the probability
    and incentive values are weighed together, 48
    challenging tasks seem to offer the best value.

The Elements of Emotional Experience
  • The 49 component of emotion involves subjective
    conscious experience that have an evaluative
    aspectpeoples 50 appraisals of events are key
    determinants in emotional experience.
  • Much of the physiological arousal associated with
    emotion occurs through the actions of the 51
    nervous system. This nervous system is
    responsible for the highly emotional 52
    -or-flight response. The involuntary nature of
    autonomic response is the reason that measures of
    autonomic activity like the GSR ( 53 (3 words))
    or polygraph can be used to detect whether
    someone is uncomfortable with what they are
    telling you (although polygraph measures are not
    all that accurate).
  • In the brain, the limbic system is the emotional
    neural circuit, with a particularly central
    role played by a structure called the 54 .
  • Behaviorally, emotions are expressed through body
    language and facial expressions. Research
    indicates considerable cross-cultural
    similarities in the ability to differentiate
    facial expressions of emotion. Cross-cultural
    similarities have also been found in the
    cognitive and behavioral components, although
    display rules, or norms for regulating
    appropriate expression of emotion vary from
    culture to culture.

Theories of Emotion
  • The 55(2 words) theory of emotion holds that you
    see a snake, your pulse races, and you feel
    afraid because your pulse is racing (emphasis on
    the physiological determinants of emotion).
  • The 56 (2 words) theory holds that you see a
    snake, the information is sent to the thalamus,
    which relays the signals simultaneously to the
    cortex and to the autonomic nervous system.
  • According to Schacter Singer, the experiences
    of emotion depends on 57 (2 words) first, then
    the cognitive 58 of that arousal.
  • Darwin viewed emotions as a product of 59 that
    evolved because they had 60 value.
  • Evolutionary theories of emotion assume that
    emotions are 61 reactions that require little
    cognitive interpretation. Robert Plutchik (1984,
    1993) has devised a model of how primary emotions
    blend together to form secondary emotions.

11
Happiness
  • Research on happiness indicates that commonsense
    notions about what makes people happy are largely
    incorrect.
  • Income (money), 62 , parenthood, intelligence,
    and attractiveness are largely uncorrelated with
    happiness (do not predict).
  • Physical health, good social relationships and ,
    63 , are modestly correlated with happiness.
  • Love, marriage, work satisfaction, and 64 are
    the only factors shown to be strongly predictive
    of happiness.
  • Research indicates that 65 feelings rather than
    66 reality is what is important in deciding
    happiness.
