Title: Motivation and Emotion


1
Motivation and Emotion
  • Ch 13 notes

2
Terminology
  • Motive stimulus that moves a person to behave in
    ways designed to accomplish a specific goal
  • Need a condition in which we require something
    we lack
  • Both biological and psychological
  • Drives forces that motivate an organism to take
    action (food gives rise to the hunger drive)

3
Instinct Theory
  • Behavior patterns that are genetically
    transmitted from generation to generation are
    instincts
  • At one time psychologists believed that human
    behavior, like that of animals, is instinctive
  • Today, most psychologists do not believe that
    human behavior is primarily motivated by instinct
    because it would need to be found throughout the
    species

4
Drive-Reduction Theory
  • Based on learning as well as motivation
  • People and animals experience a drive arising
    from a need as an unpleasant tension
  • Learn to do whatever will reduce that tension by
    reducing the drive (eat to reduce hunger drive)
  • Some drives are caused by biological needs, some
    are learned (need for )
  • Do what we can to reduce the drive to reach a
    balance homeostasis
  • Explains a lot but not all motivation

5
Humanistic Theory
  • People are also motivated by the conscious desire
    for personal growth and artistic fulfillment
  • Sometimes our drive to fulfill such needs
    outweighs our drive to meet more basic needs
  • Abraham Maslows Hierarchy of Needs
  • People rise naturally through the levels as long
    as they do not encounter overwhelming obstacles
    along the way
  • Critics say it doesnt apply to all

6
Sociocultural Theory
  • Even if basic drives such as hunger are inborn,
    cultural experiences and factors influence the
    behavior that people use to satisfy those drives
  • Foods people eat and the way they eat those foods
    are shaped by culture

7
Biological Needs
  • Can be complex because they involve psychological
    and physiological factors
  • Ex food
  • Hunger drive regulated by both biological and
    psychological factors

8
Hunger Drive
  • Mouth chewing/swallowing help satisfy hunger
    drive
  • Stomach hunger pangs felt in stomach play a role
    in hunger but are not main factors involved in
    signaling hunger
  • Blood sugar level when low, message carried to
    hypothalamus
  • Hypothalamus sends start eating message and
    stop eating message
  • If one or both dont work properly, eating
    patterns are effected

9
Psychological Influences on Hunger
  • Learning certain amounts of food/drink will
    produce feeling of well-being and relaxation can
    cause people to eat/drink when they feel upset
  • Should parents reward good behavior with food?

10
Obesity
  • More than ½ of US adults are overweight
  • 18 are obese weigh more than 30 above
    recommended weight
  • Increasing problem in the US
  • Estimated that 300,000 people die each year
    because of health problems related to excess
    weight and inactivity

11
Losing Weight
  • Adolescents should be cautious because they need
    a good deal of nourishment
  • Sound diet is one that is sensible, realistic,
    and well planned
  • Improve nutritional knowledge, decrease caloric
    intake, exercise, and substitute healthful foods
    for harmful foods
  • Dieting plus exercise is more effective than
    dieting alone

12
Causes of Obesity
  • Biological and psychological factors
  • Runs in the family, so is it inherited?
  • Not necessarily because children learn what they
    live
  • Heredity does play a major role (adoptee study)
  • May not get messages from hypothalamus to stop
    eating
  • Genes determine of fat cells a person has
  • Psychological Factors
  • Eat more under stress or negative emotions
  • Circumstances/situations (parties, tv watching)

13
Needs
  • Psychological Biological Needs
  • Some psychological needs motivate us to reduce
    tension/stimulation
  • Others actually lead us to increase the amount of
    stimulation we experience
  • Stimulus motives desires for stimulation
  • Sensory stimulation, activity, exploration,
    manipulation of the environment
  • Some have clear survival value (envir.)

14
Sensory Deprivation
  • Absence of stimulation
  • What happened to the people in the sensory
    deprivation experiment?
  • Felt very uncomfortable, felt they went through a
    terrible ordeal, had trouble concentrating and
    readjusting to their environment after the
    experiment
  • Proves the importance of sensory stimulation to
    humans

15
Sensation Seeker
  • Someone who seeks out thrilling activities

16
Why do some psychologists think exploration and
manipulation are reinforcing in and of themselves?
  • Once a person feels comfortable with an
    environment, they seek novel stimulation (new
    experiences)
  • Ex human infants and the busy boxes

17
High Achievement Motivation
  • Driven to get ahead
  • Tackle challenging situations
  • Driven to meet high personal standards of success

18
Performance v. Learning Goals
  • Performance
  • Specific goals
  • Ex gaining admission to a college, earning
    parent/teacher approval, even just avoiding
    criticism
  • Learning
  • Learning for the sake of learning
  • Can be very powerful

19
Extrinsic v. Intrinsic Rewards
  • Extrinsic
  • External rewards
  • Good grades
  • Good income
  • Most often how performance goals are rewarded
  • Intrinsic
  • Internal rewards
  • Self-satisfaction
  • Usually how learning goals are rewarded

20
Parents Role
  • Crucial importance
  • Need to encourage children to be persistent and
    find own solutions to problems
  • Create opportunities to expose children to new
    and stimulating experiences (learning goals)
  • Reward kids with toys for good grades, punishment
    for bad grades (performance)
  • Overall, tend to be generous with praise to do
    well and less critical when their children do
    poorly

21
Cognitive Consistence Theory
  • People behave in ways expected of them
  • Primarily motivated by the beliefs we hold about
    how others view us
  • Most people prefer that the pieces of their
    lives fit together

22
Balance Theory
  • People need to organize their perceptions,
    opinions, and beliefs in a harmonious manner
  • Do this to maintain a cognitive balance by
    holding consistent views and by being with people
    who share their beliefs and values

23
  • What causes imbalance?
  • A major area of disagreement between 2 people who
    have strong feelings for each other
  • Tends to upset people
  • What causes a state of nonbalance?
  • Not having feelings toward someone
  • Leaves people feeling indifferent

24
  • According to the cognitive-dissonance theory, why
    do people behave the way that they do?
  • Most people want their thoughts and attitudes
    (cognitions) to be consistent with their actions
  • When we become aware that there is an
    inconsistency (dissonance) we feel unpleasant
    which causes inner tension that can be
    uncomfortable
  • Why do people desire affiliation with others?
  • Humans are social beings and need to be with
    others
  • During adolescence, this need is VERY strong

25
What happens when we experience strong emotions?
  • Activity in autonomic nervous system anxiety
    for example triggers activity of sympathetic
    division of autonomic nervous system
  • How do emotions have biological, cognitive, and
    behavior components?
  • Anxiety makes heart race, breathe rapidly, sweat,
    muscles tense (bio)
  • Anxiety idea that something bad might happen
    (cognitive)
  • Anxiety might lead a person to try to escape from
    a situation (behavioral)

26
Our Emotional State Effects Our Perceptions of
Our Surroundings
  • Happier people usually think the world is a
    happier, safer place
  • Tend to make decisions more readily and are more
    satisfied with their lives
  • Unhappy people tend to feel like gloom is
    settling in over everything in their lives
  • Shows that happiness and unhappiness create their
    own momentum
  • Happier we are, the more likely we are to help
    others

27
Anger
  • Response to insult or attack
  • Assertive reaction vs. hostile reaction
  • Can go and speak with the person who made them
    angry about whatever it was that made them angry
    rather than getting revenge
  • Assertiveness is more effective because it allows
    a person to approach his/her feelings and reduce
    them while not causing harm to themselves or
    others

28
Facial Expressions
  • Probably inborn
  • The ways that specific emotions are expressed
    appear to be the same around the world

29
Theories of Emotion
  • Opponent-Process Theory
  • Commonsense Approach
  • James-Lange Theory
  • Cannon-Bard Theory
  • Theory of Cognitive Appraisal

30
Opponent-Process Theory
  • Emotions come in parts with one followed by its
    opposite
  • Eventually restores a balance

31
Commonsense Approach
  • When something happens to a person in a certain
    situation, the person quickly interprets the
    situation
  • Interpretations trigger body sensations that
    signal a feeling or emotion
  • Emotions trigger a behavior
  • This approach (broad view) has influenced the
    next 3 theories

32
James-Lange Theory
  • Peoples emotions follow, rather than cause,
    their behavioral reactions to situations
  • People act first then react emotionally according
    to the way they acted
  • Certain situations trigger reactions
    instinctive bodily response patterns that include
    specific feelings and behaviors
  • Suggests people can change their feelings by
    changing their environment

33
Problems with James-Lange Theory
  • Cognition has little role in determining behavior
  • Minimizes the role of personal values and choice
    as factors in human behavior

34
Cannon-Bard Theory
  • Emotions accompany bodily responses that are
    aroused by external stimuli
  • Situation triggers external stimulus that is
    processed by the brain, brain stimulates bodily
    changes and cognitive activity (experience of the
    emotion) happens simultaneously
  • Emotions are not produced by bodily responses
  • A 2 stage reaction is involved bodily response
    followed by an emotional reaction

35
Theory of Cognitive Appraisal
  • Argues that all emotions have basically similar
    bodily response patterns
  • Body reacts in physically similar ways with
    different emotions it experiences
  • Maintains that the way people label an emotion
    depends on their cognitive appraisal of the
    situation
  • Cognitive appraisal that occurs is based on many
    factors analysis of situation and ways other are
    reacting in same situation

36
Criticism of Cognitive Appraisal
  • Studies designed to support the theory often
    yield different results when repeated
  • Lacking test-retest reliability

37
So, are any of the theories correct?
  • No
  • None are perfect
  • People are very complex
  • Emotions then are also complex
