Title: Unit V


1
Unit V Motivation and Emotion
  • Memory/Cognition What we know about the world
  • Learning How we make associations between
    causes and effects
  • Motivation What effects do we really desire

2
Learning
  • The studies of how learning works are some of the
    earliest of psychology and are the most
    informative of the debate of the soul.

3
Habituation
  • Habituation the simplest and most basic form of
    learning
  • It is the decline in the tendency to respond to a
    stimuli after repeated exposure.
  • Not only do our senses tune out constant stimuli,
    but we also consciously learn to ignore them.
  • Habituation is an adaptive advantage as organisms
    need to function without constantly reacting to
    threatening stimuli

4
Habituation works closely with memory
  • Short-term habituation responses to stimuli
    decrease quickly after repeated exposures over a
    short time. Eg. 300 loud sounds over 5 hours.
  • Spontaneous recovery after an extended delay,
    short term habituation is extinguished and the
    response returns.
  • Long term habituation responses to a stimuli
    decrease gradually after repeated exposures over
    a long time. Eg. 1 loud sound per day for 1 month.

5
Classical Conditioning
  • Habituation is the recognition of events as
    familiar, learning is the relationship between
    events and circumstances. These relationships are
    called associations.
  • Experimental study of associations did not begin
    until Ivan Pavlov (1849-1936)

6
Pavlovs Dog
  • A dog was prepared for this experiment by having
    a small operation exposing the salivary gland to
    the surface, which made it possible to measure
    salivation automatically.Then the dog, which is
    fastened by leashes such that he cannot move, is
    given food while ringing a bell. This procedure
    was repeated several times.

7
  • Before training
  • US (food in mouth) ------------? UR (salivation)
  • CS (bell ringing) --------------? No response
  • Training
  • CS (bell ringing) US ( food in mouth)
  • After training
  • CS (bell ringing) ----------------? CR
    (salivation) formerly the UR
  • Once the training is finished, the dog will now
    salivate at the sound of the bell, which
    previously had no effect on the dog.

8
The Reflex
  • Unconditioned reflex The innate relationship
    between stimuli and involuntary responses.
    Composed of an unconditioned stimulus (US) and an
    unconditioned response (UR)
  • Conditioned reflex Relationships between
    stimuli and responses that result from
    experience. Composed of a conditioned stimulus
    (CS) and a conditioned response (CR)

9
Reinforcement
  • Through training, the unconditioned stimulus is
    paired with the conditioned stimulus.
  • Trials where the US occurs with the CS are
    reinforced
  • Trials where the US occurs without the CS are
    unreinforced
  • The tendency of the CS to elicit the CR, and the
    strength of the CR, go up the more often they are
    reinforced this can be plotted on the learning
    curve.

10
The Learning Curve
  • Learning curve Learning is proportional to
    prediction error (received-predicted reward) and
    reaches an asymptote as the prediction error
    approaches zero. prediction, and are learning
    constants, reward.

11
Unlearning
  • Extinction the greater the number of
    unreinforced trials, the weaker the strength of
    the CR until it no longer occurs.
  • Reconditioning extinct CRs can be reconditioned
    through further reinforced trials. Reconditioning
    a CS takes fewer trials than the initial
    conditioning.
  • Spontaneous recovery an extinguished CR will
    reappear after a rest interval.

12
Response Strength
  • There are 3 ways to measure the strength of the
    CR
  • Response amplitude The intensity of the
    response. Eg. How much saliva the dog produced.
  • Probability of response The proportion of
    trials in which the CR occurred when the CS was
    presented alone. Eg. The number of times the dog
    drooled when hearing the bell alone
  • Response latency the time from the presentation
    of the CS to the CR. Eg. The amount ot time it
    took the dog to drool after hearing the bell
    alone.

13
The implications of Pavlovs discoveries has been
instrumental in many different fields eg.
Advertising
14
  • Generalization the CS does not have to be
    identical in every trial, a range of variation
    will still elicit a CR even though the strength
    is reduced, this reduction is called
    generalization decrement.
  • Discrimination - subjects can be conditioned to
    distinguish between very small differences in
    stimuli.
  • pairing slightly different stimuli with
    reinforced trials, and others with unreinforced
    trials
  • Discrimination is important because it shows that
    learning is taking place. It takes multiple
    trials to get the subject to remember which is
    the right CS and which is the unreinforced CS.

15
Fear
  • Studies in fear have been linked with classical
    conditioning from its inception

16
Phobias
  • When a negative stimulus (an electric shock) is
    paired with a CS (a light going on) any learned
    behaviour will cease this is called response
    suppression.
  • Many fears that adults have is closely linked
    with classical conditioning. If the fears are
    intense enough, they can be deemed phobias.

17
CR and UR
  • Fear highlights an important relationship between
    the CR and the UR the CS (the bell) is a
    signal for the US (the food) but is not a
    substitute for it.
  • The CS causes the subject to prepare for the US
    and the subsequent CR. This occurs unconsciously
    and involuntarily.

18
Compensatory Reaction
  • Compensatory reaction The conditioned response
    works opposing the unconditioned response
  • When diabetics receive insulin shots, their
    bodies react to the CS of the needle and the
    injection process by raising its blood sugar
    level.
  • The same will occur in drug addicts the drug
    heroin induces feelings of euphoria, relaxation,
    and relief from pain. Therefore the CS of the
    drug needle and the usual injection procedures
    can cause the body to ache, to become restless,
    and depressed.

19
  • This requires the addict to raise the dose of the
    injection to attain the same effect each time
    they inject.
  • However, in the absence of the usual CS, the body
    will not compensate and the same dosage will be
    fatal.

20
Journal
  • What makes horror movies so frightening?
  • Explain how they work (sights and sounds) to make
    changes occur to your body and behaviour.

21
Instrumental Conditioning
  • Studies in Instrumental Conditioning began before
    Pavlov with the development of the theory of
    evolution by Charles Darwin were we just a type
    of ape? Or was mankind special in some way?

22
E.L. Thorndike
  • E.L. Thorndike became one of the most important
    figures in the history of science with his work
    with problem solving and animals.

23
  • Thorndike placed a cat in the cage and observed
    how the cat learned to escape. The cat was then
    put back in the cage and Thorndike timed how long
    it would take for the cat to master the solution
    to the box (his chosen measure of learning).
  • Thorndike plotted a learning curve for the cats
    speed of success.

24
The learning curve
  • What would be expected to happen IF the cat was
    intelligent?
  • The cat would learn quickly sudden insight
  • What would be expected to happen IF the cat was
    NOT intelligent?
  • The cat would learn gradually trial and error

25
The Law of Effect
  • Based on his results, Thorndike proposed his Law
    of Effect
  • The consequences of a response determine whether
    the tendency to perform it is strengthened or
    weakened. If the response is followed by a
    satisfying event (e.g., access to food), it will
    be strengthened of the response is not followed
    by a satisfying event, it will be weakened.

26
  • When introduced to a new environment, a subject
    will produce infinite random behaviours. As some
    behaviours lead to success and others to failure,
    certain behaviour patterns will dominate and
    others become extinguished. Note the absence of
    reason or intelligence.

27
B.F. Skinner
  • Most of the early research on instrumental
    learning was performed by B. F. Skinner. Skinner
    proposed that instrumental learning and classical
    conditioning were fundamentally different
    processes.

28
Classical vs. Instrumental Conditioning
  • Because the response precedes the reinforcement,
    rather than follows it.
  • Because the response is voluntary, it must be
    selected from an infinite number of possible
    actions.

29
Operant Conditioning
  • Instrumental Conditioning also called Operant
    Conditioning The learning process through which
    the consequence of an operant response affects
    the likelihood that the response will be produced
    again in the future.

30
Skinner Box
  • Skinner devised a box in which a mechanism can be
    operated to produce a reinforcer. The animal can
    be left in the box to respond however it chooses.
    Skinner measured the number of responses as an
    indication of learning.

31
Man vs. Animal
  • Skinner argued that everything we do can be
    attributed to this process of reinforcement
    whether we are aware of the consequences of our
    actions or not.

32
Skinner identified three consequences for
behaviour
  • 1) Positive Reinforcement - Any stimulus that
    increases the probability of a behaviour
  • 2) Negative Reinforcement - Any stimulus whose
    removal increases the probability of a behaviour.
  • 3) Punishment - Any stimulus whose presence (or
    absence in negative reinforcement) decreases the
    probability of behaviour.
  • Skinner thought that punishment was the least
    effective of the 3 possible consequences for
    learning.

33
  • Shaping reinforcing behaviours that are
    increasingly similar to the desired responses.

34
2 important facts
  • The larger the reinforcer, the more rapid the
    extinction.
  • The greater the number of training trials, the
    more rapid the extinction.

35
Reinforcement schedules
  • Continuous Reinforcement every response is
    reinforced
  • Partial Reinforcement only some responses are
    reinforced.
  • Learning is faster with continuous reinforcement
    but extinction takes longer with partial
    reinforcement.

36
Four basic schedules of partial reinforcement
  • Ratio schedules reinforcer given after some
    number of responses.
  • Interval schedules reinforcer given after some
    time period.
  • Fixed the number of responses or time period is
    held constant.
  • Variable the number of responses or the time
    period is varied.

37
Resulting behaviour
  • Fixed-Ratio bursts of responses.
  • Variable-Ratio high, steady rate of responding.
    (Slot machines work on a V-R schedule).
  • Fixed-Interval pauses with accelerating
    responses as the time approaches.
  • Variable-Interval after training, a slow, steady
    pattern of responses is usually seen.

38
Cognitive Learning
  • Opposing the mechanical view of learning and
    emotions depicted by Skinner, Thorndike and
    Pavlov were other scientists who believed that
    there was more going on than simple trial and
    error they felt that even the simplest animals
    were forming knowledge.

39
Edward Tolman
  • Edward Tolman believed that animals were
    acquiring knowledge about their surroundings he
    called cognitions.
  • He found that rats being transported around his
    laboratory were showing evidence that they had
    learned something about the space in later tests.

40
Test subjects were forming relationships between
the CS and US based on 2 factors
  • Contiguity togetherness in time studies showed
    that there was an optimum amount of time that
    should pass between the CS and the US for
    conditioning.
  • Contingency the occurrence of the US depends on
    the CS there are a multitude of stimuli that
    occur before the US that could also be
    interpreted as the CS. Subjects learned which of
    these stimuli signalled the coming of the US by
    experiencing the absence of the CS and the
    corresponding absence of the US.

41
These studies indicated that the animals were
reasoning that the CS was a probable indicator of
the US more than other stimuli occurring in the
environment at the time.
42
Fear vs. Anxiety
  • When these ideas are applied to negative stimuli
    (electric shocks) they highlight the difference
    between fear and anxiety.
  • When a tone precedes an electric shock 60 of
    trials, subjects would react to the tone with
    tension and response suppression - fear.
  • When there was no stimuli that would predict that
    a shock was coming reliably, the animal
    constantly shows fear and suffers long term
    physiological consequences anxiety

43
Response Control
  • Subjects that were tested in conditions where
    they could respond to avoid their negative
    stimuli developed response control
  • Infants who can control the movement of their
    crib mobiles show more interest in them.

44
  • Subjects tested in conditions where they could
    not respond to avoid negative stimuli displayed
    learned helplessness an acquired sense that
    environmental control is not possible so no
    efforts are made.

45
  • Two groups of dogs were strapped into hammocks
    and subjected to electric shocks after the
    presentation of a 3 second tone. The dogs in
    group A were given to ability to avoid these
    shocks by pressing a level with their nose. The
    shocks of the two groups were linked, if the dogs
    in group A avoided the shock, so would their
    partners in B. Each group of dogs received the
    same level of shocks but only the dogs in group A
    could control them.

46
  • When the dogs were then placed in a shuttle box
    (a cage divided in half by a low partition) A
    tone would precede a shock through the floor of
    the cage. The dogs from group A quickly learned
    to jump the divider at the tone to avoid the
    shock the dogs in group B simply laid down on
    the floor of the cage and took the shocks.

47
  • Learned helplessness has been linked to
    depression because they both carry the same
    symptoms (suppressed immune systems, weight loss,
    excessive sleep, etc.)

48
Motivation
  • Motivation the needs, wants, interests, and
    desires that propel people in certain directions

49
Humans display a huge range of goal-directed
behaviour. These behaviours can be highly complex
and their dynamics known only to the agent
  • These can be divided into two main categories
  • Biological motives originate in bodily needs
    such as hunger or excretion.
  • Social motives originate in social experiences
    such as achievement

50
Biological Motives
  • Hunger
  • Thirst
  • Sex
  • Temperature
  • Excretion
  • Sleep
  • Activity
  • Aggression

51
Social Motives
  • Achievement
  • Affiliation
  • Autonomy
  • Nurturance
  • Dominance
  • Exhibition
  • Order
  • Play

52
Attribution Errors
  • Fundamental Attribution Error (FAE) - The bias to
    attribute behaviour to stable internal causes
    rather than external ones

53
FAE expression factors
  • What if we tell people what behaviours they must
    express?
  • This has been shown to be consistent even when
    observers ascribe the participants into their
    opinion groups themselves. (Gilbert and Jones
    1986)
  • What if we find out that there might be some kind
    of agenda explaining someones behaviours?
  • Some dispositional factors have also been shown
    to impact FAE.
  • When observers are informed that the opinion of a
    participant matches that of an authority figure
    who could control rewards or punishments in the
    participants future FAE diminishes. (Fein 2001)

54
Gilbert and Malone (1995) have shown that FAE
involves a two step attribution process
  • First - We observe behaviour and make an
    automatic and unconscious inference toward
    disposition
  • Second - We make a controlled and conscious
    process inquiry into the situational factors that
    could explain the behaviour
  • FAEs occur when we do not proceed to the second
    step.
  • We are distracted by other tasks
  • We believe that our first explanation based on
    dispositional inferences is a sufficient
    explanation

55
Self-serving bias attributing our successes to
internal dispositional factors and blame failures
on external situational factors
  • Johnson et al
  • Aims to investigate the effect of performance
    improvements on the perceptions of teachers
    assessments of their abilities.
  • Methods Participants were asked to teach
    students how to multiply by using a one-way
    intercom in two stages. The control group
    performed well in both phases, the first
    experimental group showed no improvement from the
    first to the second phase, the second group
    showed improvement. The participants were then
    asked to explain the improvement in the second
    phase
  • Conclusions When there was no improvement in
    the student, the participants ascribed it to a
    lack of ability in the student, when there was
    improvement, the participants ascribed this to
    their abilities as teachers.

56
Some exceptions to the SSB
  • We are more likely to rely on SSB when we fail in
    domains in which we cannot improve but we are
    more likely to attribute failure to internal
    dispositions if there is something we can improve
    on in the future.
  • Abrahamson (1989) found that people with
    depression often rely on an attributional style
    that links success to external and failure to
    internal factors
  • Zuckerman (1979) meta-analysis of SSB studies
    show that the effect stems from a desire to
    maintain self-esteem
  • Hiene (1999) found less desire to seek
    self-esteem reinforcing experiences in
    collectivist cultures and therefore found less
    SSBs occurring in that culture.
  • Miller and Ross (1975) SSB has rational uses
    apart from self-esteem enhancement. Logically,
    effort changes with success. If increased effort
    does not increase performance then the conclusion
    must be the nature of the task, if increased
    effort yields increased results, then the success
    is attributable to the self.

58
Social Identity Theory (Tajfel et al. 1979)
  • Based on four interrelated concepts
  • Social categorization
  • Social identity
  • Social comparison
  • Positive distinctiveness

59
Social Categorization
  • Divides the environment into two groups
  • Ingroup
  • Outgroup
  • This has the effect of category accentuation
    effect
  • reducing perceived variability in the ingroup
  • reducing perceived variability in the outgroup
  • increasing perceived variability between the
    ingroup and the outgroup

60
  • Social Identity
  • Our self-concepts formed by being members of
    various social groups based on intergroup
    behaviours rather than interpersonal ones. People
    can have several of these
  • Where do student-teacher relationships fit in
    here?
  • Social Comparison
  • We continuously compare our ingroups to relevant
    outgroups to maintain positive social identities.
  • Positive distinctiveness
  • The need to show that your ingroup is superior to
    an outgroup

61
Explain these concepts as they are expressed in
the film The Breakfast Club
62
These lead to intergroup behaviours with some
general characteristics
  • 1) Ethnocentrism
  • Positive behaviours by ingroup members attributed
    to dispositions
  • Negative behaviours by ingroup members attributed
    to situational factors
  • Positive behaviours of outgroup members
    attributed to situational factors
  • Negative behaviours or outgroup members
    attributed to dispositions
  • 2) In group favoritism
  • 3) Intergroup differentiation - altered behaviour
    to emphasize group differences
  • 4) Stereotypical Thinking ingroup members and
    outgroup members are perceived according to
    stereotypes
  • 5) Conformity to ingroup norms acting according
    to defined behaviours

63
Minimal Group Paradigm Tajfel et al (1971)
  • Aims To determine the effect of group
    membership on behaviours
  • Method participants were divided into groups
    randomly but told that their group membership was
    based on personal taste in artists. They were
    then asked to assign points to other members of
    the study according to predetermined rules.
  • Conclusions the participants exhibited strong
    SIT tendencies such as favoring members of their
    own group and assigning points in such a way as
    to enhance the difference between the groups
    rather than increase the benefit to their own
    group.
  • Despite criticisms of demand characteristic
    validity issues these findings have proven
    consistent in real-life situations and when
    participant do not know they are being observed.
  • Mummendey and Otten (1998) - The effect is more
    powerful when distributing rewards than when
    distributing punishments.
  • Dobbs and Crano (2001) the effect is diminished
    when subjects must justify their reward
    strategies afterwards.

64
Stereotypes
  • Stereotypes widely held evaluative
    generalizations about a group of people.
  • Assigns similar characteristics to all members of
    a group despite variability
  • Has all the properties of schemas
  • Based on defining characteristics gender, age,
    race, etc.
  • Are persistent across cultures

65
Formation of stereotypes
  • Four theories of the structure and function of
    stereotypes
  • Social-cognitive theories
  • SIT
  • Systems-justification theory
  • Social representation theory

66
Stereotype formation social cognitive theories
  • Limited capacities for cognitive processing
  • Complex world increasing complexity
  • Social categorization simplifies cognitive
    processing
  • Social categorization stereotypes
  • Energy-saving devices
  • Automatically activated
  • Stable and resistant to change
  • Affect behaviour

67
Stereotype Formation Social Identity Theory
  • Stereotypes based on category accentuation
    effect and positive distinctiveness.
  • Sherman et al (2009) we pay more attention to
    those ingroup and outgroup members that maximize
    positive distinctiveness.
  • Ethnocentrism leads biased attributions to
    behaviours of ingroup and outgroup members.

68
Stereotypes Systems justification theory
  • Jost and Banaji (1994) stereotypes are used to
    justify social and power relations in society.
    eg. rich vs. poor
  • SIT and social-cognitive approaches to
    stereotyping cannot explain negative
    self-stereotyping internalization of negative
    stereotype attributes in disadvantaged groups

69
Stereotypes Social-representations theory
  • Moscovici (1984) Stereotypes emerge from group
    beliefs shared by a society rather than by
    individual schema activation.
  • Both SJT and SRT emphasize negative perceptions
    stereotypes have been shown to be predominantly
    negative (Fiske and Taylor 2008)

70
Stereotypes and performance
  • Stereotype threat effect performance impairment
    that results when individuals asked to carry out
    a task are made aware of a negative stereotype
    held against them regarding their groups ability
    to perform that task well.
  • Spencer et al (1999) informing females that
    they perform statistically worse than men on math
    tasks prior to taking a math test lowered their
    scores
  • Steele and Aronson (1995) performance of
    African-Americans on verbal skills tasks was
    lower when they were asked to indicate their race
    prior to beginning.

71
Origins of Personality
  • Although people have a limited number of
    biological needs (10 15) they can be socialized
    to have an unlimited number of social needs.
  • The strength of each need varies from person to
    person and becomes a crucial factor in defining
    identity and personality.

72
Biological needs - hunger
  • Early research into hunger showed a string
    correlation between stomach contractions and
    hunger researchers thought that hunger was
    caused by stomach contractions
  • But patients who have had their stomachs removed
    for medical reasons continued to experience hunger

73
3 causes of hunger
  • Brain regulation
  • Blood sugar levels
  • Hormones

74
Brain regulation
  • The experience of hunger is controlled in the
    hypothalamus
  • Lateral Hypothalamus turned hunger off
  • Ventromedial Hypothalamus turned hunger on
  • Paraventricular Hypothalamus works with both

75
Glucose regulation
  • Glucose a simple sugar that is an important
    source of energy
  • Most of what we consume is converted into glucose
  • Low blood sugar levels are associated with hunger
  • High blood sugar levels are associated with
    satedness
  • Glucostatic theory neurons sensitive to glucose
    in the surrounding fluid send signals to the
    brain to stop/start eating

76
Digestive Regulation
  • Vagus nerve sends signals to the brain when the
    stomach walls are stretched
  • Other nerves carry signals that depend on how
    rich in nutrients the contents of the stomach are.

77
Hormonal regulation
  • Insulin hormone secreted in the pancreas. It
    must be present for cells to extract glucose from
    the blood.
  • High insulin hunger
  • Low insulin no hunger
  • Leptin produced by fat cells throughout the
    body. Provides information to the hypothalamus
    about the bodys fat levels
  • High leptin low hunger
  • Low leptin high hunger

78
What are the key environmental factors governing
eating?
  • Learned preferences
  • Food-related cues
  • Stress

79
How does classical conditioning play a role in
eating?
  • Preferences in taste are learned through
    associations created in classical conditioning.

80
If you force a child to eat, will they eventually
like it? Why or why not?
  • Coercion tends to have a negative effect on
    preference for a food. They have learned an
    aversion to the food from the unpleasant
    association created when they were exposed to it.

81
How does memory influence eating?
  • A key component to hunger is our memory of the
    last time we ate. The appropriate duration
    between meals is learned through socialization.

82
What effect does the sight of food have?
  • The sight and smell of food trigger hunger. This
    includes its appetizingness, the effort required
    to eat it, and its availability.

83
How are stress and eating related? Is this
relationship the same for men and women?
  • The arousal related to stress, rather than stress
    itself, leads to more eating. This is common in
    women more than in men.

84
Define obesity.
  • The condition of being overweight, more than 20
    above the ideal weight.
  • What are the negative effects of obesity?
  • Overweight people are susceptible to diabetes,
    high blood pressure, respiratory problems,
    stroke, arthritis, and back problems.

85
What has brought on obesity in modern times?
  • Only recently have humans stopped eating wild
    foods and switched to domesticated, high sugar
    foods. Our bodies have not adapted to the new
    diet.

86
How common is dieting?
  • 24 of men and 40 of women diet

87
Can you be born to be fat? Explain. What have
scientists studied to answer this?
  • Scientists have discovered through studying
    adopted children and twins raised in different
    families that people can be born with a
    vulnerability to obesity. Genetic factors account
    for 61 of the variation in weight of women and
    73 in men.

88
Define body set point. Can you change your bodys
set point?
  • Set Point a natural point of stability in body
    weight. Long term excessive eating can raise the
    bodys set point but it is very difficult to
    lower it.

89
Achievement vs. Affiliation
  • Achievement the need to master difficult
    challenges, to outperform others, and to meet
    high standards of excellence.
  • This becomes more prominent in competitive
    situations and can be measures for entire
    societies through studying literature or movies.

90
The tendency to pursue achievement depends on the
following factors.
  • The strength of the motivation to achieve.
  • The estimate of the probability of success
  • The incentive value of success.

91
Affiliation
  • Affiliation the need to associate with others
    and maintain social bonds.
  • Also included the fear of rejection, jealousy,
    and depression.

92
TAT Test
  • Achievement and affiliation levels in people can
    be measured with a Thematic Apperception Test
    (TAT) in which subjects are shown stimuli with
    ambiguous meaning. They are then asked to
    construct a fictional narrative for the image.
    These narratives can be analyzed for their
    achievement or affliative content.

  • Observe the following image carefully. Construct
    a narrative (a story) that could explain the
    scene you are observing.
  • Bring in your narrative and exchange it with a
    partner. Analyze each narrative for its
    affiliative or achievement motives.

Emotions
  • There are 3 elements to emotional experience
  • 1. subjective conscious experience (cognitive)
  • 2. bodily arousal (physiological)
  • 3. characteristic overt expression (behavioral)

97
The cognitive component
  • Emotions happen to us rather than something that
    we make happen
  • Some degree of emotional control is possible
    (emotional intelligence)
  • Peoples conscious appraisals of situations are
    key determinants of emotions evaluation of an
    emotion as good or bad

98
The physiological component
  • The biological reaction to situations involves
    structures of the brain, neurotransmitters, and
    the endocrine system.
  • Autonomic Nervous System regulates the activity
    of the glands, smooth muscles, and blood vessels.
    fight or flight response
  • Galvanic Skin Response the change in electrical
    conductivity of the skin that occurs when the
    sweat glands of the skin increase their activity.

99
Autonomic Responses
  • Sympathetic
  • Pupils dilated
  • Dry mouth
  • Goose bumps
  • Sweaty palms
  • Dilated lungs lungs
  • Increased heart rate
  • Adrenal activity
  • Inhibited digestion
  • Parasympathetic
  • Pupils constrict
  • Salivating mouth
  • No goose bumps
  • Dry palms
  • Constricted lungs
  • Decreased heart rate
  • Decreased activity
  • Stimulated digestion

100
Brain Activity
  • The emotional centers of the brain are the
  • Hypothalamus
  • Amygdala
  • Limbic system
  • The amygdala plays a central role in processing
    emotional stimuli

101
The Amygdala
  • The thalamus process emotional stimuli
    immediately and passes them on to the amygdala or
    the cortex.
  • If the amygdala detects a threat then it triggers
    the hypothalamus to create an autonomic and
    endocrine response.

102
The behavioral component
  • Emotions are expressed in body language or
    nonverbal behavior.
  • When evaluating photographs of facial
    expressions, subjects successfully identify 6
    emotions
  • Happiness
  • Disgust
  • Sadness
  • Fear
  • Surprise
  • Anger

103
Facial responses
  • Evidence suggests that facial muscles send
    signals to the brain that help the cortex
    interpret emotional stimuli
  • Subjects asked to adopt a facial expression will
    report feeling that emotion
  • Subjects who have been blind since birth still
    adopt facial expressions like everyone else.

104
Theories of emotion
  • James-Lange Theory the perception of arousal
    leads to the conscious experience of fear
    different patterns of autonomic activation lead
    to different emotions
  • Cannon-Bard Theory emotion occurs when the
    thalamus sends signals directly to the cortex and
    the autonomic nervous system.
  • Schachters Two-Factor Theory Emotion depends
    on two factors 1) autonomic arousal 2) cognitive
    interpretation of that arousal. You feel a
    certain way and search for reasons why.

105
Emotions
  • Darwin emotions developed because of their
    adaptive value. Emotions are innate reactions to
    specific stimuli. They are recognizable without
    thought.

106
Innate emotional vocabulary
  • Humans are born with 6 10 emotions that
    originate in the subcortical brain
  • fear, anger, joy, disgust, interest, surprise.
  • All other emotions are the result of
  • 1) variations in intensity of emotions
  • 2) blending of several different emotions.

The Nature of Personality
  • Personality is the consistent disposition to
    behave a certain way in a variety of situations.

109
Personality can be described according to 5
Factors
  • Agreeableness people who are sympathetic,
    trusting, cooperative, modest, and
    straightforward vs. People who are suspicious,
    antagonistic, and aggressive
  • Openness to experience people who are curious,
    flexible, vivid fantasy, imaginative, artistic,
    and unconventional - a key determinant of
    political attitudes.
  • Neuroticism people who are anxious, hostile,
    self- conscious, insecure and vulnerable. It is
    also called negative emotionality.
  • Extraversion people who are outgoing, sociable,
    upbeat, friendly, assertive, and gregarious. Also
    called positive emotionality.
  • Conscientiousness people who are diligent,
    disciplined, well-organized, punctual, and
    dependable. It is also called constraint and is
    associated with success and high productivity.

110
Personality theory
  • The 5 Factors can describe behaviour, but they
    dont account for its development and processes.
  • There are 4 main groups of personality theories
  • Psychodynamic theories
  • Behavioural theories
  • Humanistic theories
  • Biological theories

111
Psychodynamic Theory
  • Based on the work of Sigmund Freud
  • Psychodynamic theory explains motivation,
    personality, and disorders by focussing on the
    influence of early childhood experiences,
    unconscious motives and conflicts, and coping
    with sexual and aggressive urges.

112
Freud proposed three components of personality
behaviour was the result of interactions between
these three parts.
  • Id
  • Ego
  • Superego

113
Id
  • Id the primitive, instinctual component that
    operates according to the pleasure principle it
    demands immediate gratification of raw biological
    urges. Its thinking is primitive, illogical,
    irrational, and fantasy oriented.

114
Ego
  • Ego the decision-making component that operates
    according to the reality principle, which seeks
    to delay gratification of the ids urges until
    the socially acceptable moment can be found. Its
    thinking is rational, realistic, and problem
    solving.

115
Superego
  • Superego the moral component that incorporates
    social standards about right and wrong. It
    emerges from the ego at approx. 3 to 5 years old.

116
Freud believed that there were 3 levels of
awareness
  • the unconscious thoughts. Memories, and
    desires that are below the level of consciousness
    but exert a large effect on behaviour
  • the preconscious - material just beneath the
    level of consciousness but that can be easily
    retrieved.
  • the conscious everything one is aware of at any
    given moment.

Anxiety
  • Anxiety is caused by conflict between the 3
    components of personality. We deal with this
    anxiety with defense mechanisms unconscious
    reactions that protect a person from unpleasant
    emotions (eg. Anxiety or guilt)

119
Defense Mechanisms
  •  Repression keeping distressing thoughts and
    feelings buried in the unconscious.
  • Projection Attributing ones own thoughts,
    feelings, or motives to someone else.
  • Displacement Diverting emotional feelings from
    their original source to a substitute target.
  • Reaction formation Behaving in a way that is
    exactly opposite of ones true feelings
  • Regression A reversion to immature patterns of
    behaviour.
  • Rationalization Creating false but plausible
    excuses to justify unacceptable behaviour.
  • Identification Bolstering self-esteem by
    forming an imaginary or real alliance with some
    person or group.

120
Behavioural Perspectives
121
Albert Bandura
  • Albert Bandura believed in much of Skinners
    ideas of conditioning but added environmental
    factors in a theory called reciprocal determinism
    the idea that internal mental events, external
    environmental events, and overt behaviour all
    influence one another.
  • In essence, people can control their own
    conditioning.

122
Observational Learning
  • Observational learning occurs when an organisms
    responding is influenced by the observation of
    other models a person whose behaviour is
    observed by another (often people who are
    attractive or powerful).
  • People are more likely to follow a models
    behaviour when they see it leads to positive
    outcomes.

123
Humanistic Perspectives
  • Humanism is a theoretical orientation that
    emphasizes the unique qualities of humans
    especially for their potential for growth and
    freedom
  • The persons subjective view of the world is more
    important than objective reality

124
Carl Rogers
  • Carl Rogers believed in the construct of the
    self a collection of beliefs about ones own
    nature, unique qualities, and typical behaviour.
  • People tend to distort their experiences to
    promote a favourable self-concept

125
Incongruence
  • Incongruence the gap between the self concept
    and actual experience
  • Experiences that are conflicting with our self
    concept cause incongruence and are the primary
    source of anxiety.
  • Individuals behave defensively to avoid anxiety
    and incongruence. They will ignore, deny, and
    distort reality to preserve or enhance their
    self-concept.

126
Abraham Maslow
  • Abraham Maslow Proposed that human motivation
    can be organized into a hierarchy of needs a
    systematic arrangement of needs according to
    priority in which basic needs must be met before
    less basic needs.
  • The satisfaction of basic needs leads to the
    activation of needs at the next level up. Humans
    have an innate drive to achieve a higher state of
    being progression, and feel anxiety when lower
    needs are not being met regression.

127
7 Levels of needs
  • Physiological needs
  • Safety and security needs
  • Belongingness and love needs
  • Esteem needs
  • Cognitive needs
  • Aesthetic needs
  • Self-actualization

Progression
Regression

129
Self-actualization
  • Self-actualization the need to fulfill ones
    potential. Persons who achieve self-actualization
    have exceptionally healthy personalities, marked
    by continuous personal growth.

130
Characteristics of self-actualized individuals
  • Clear perception of reality and comfortable
    relations with it
  • Spontaneity, simplicity, and naturalness
  • Problem centering (having something outside
    themselves they must do as a mission)
  • Detachment and need for privacy
  • Continued freshness of appreciation
  • Mystical and peak experiences
  • Feelings of kinship and identification with the
    human race
  • Strong friendships, but limited in number
  • Democratic character
  • Ethical discrimination between good and evil
  • Philosophical, unhostile sense of humor
  • Balance in polarities of personality
