Title: Unit V
1Unit 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
2Learning
- The studies of how learning works are some of the
earliest of psychology and are the most
informative of the debate of the soul.
3Habituation
- 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
4Habituation 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.
5Classical 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)
6Pavlovs 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.
8The 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)
9Reinforcement
- 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.
10The 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.
11Unlearning
- 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.
12Response 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.
13The 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.
15Fear
- Studies in fear have been linked with classical
conditioning from its inception
16Phobias
- 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.
17CR 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.
18Compensatory 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.
20Journal
- What makes horror movies so frightening?
- Explain how they work (sights and sounds) to make
changes occur to your body and behaviour.
21Instrumental 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?
22E.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.
24The 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
25The 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.
27B.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.
28Classical 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.
29Operant 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.
30Skinner 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.
31Man 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.
32Skinner 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.
342 important facts
- The larger the reinforcer, the more rapid the
extinction. - The greater the number of training trials, the
more rapid the extinction.
35Reinforcement 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.
36Four 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.
37Resulting 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.
38Cognitive 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.
39Edward 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.
40Test 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.
41These 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.
42Fear 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
43Response 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.)
48Motivation
- Motivation the needs, wants, interests, and
desires that propel people in certain directions
49Humans 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
50Biological Motives
- Hunger
- Thirst
- Sex
- Temperature
- Excretion
- Sleep
- Activity
- Aggression
51Social Motives
- Achievement
- Affiliation
- Autonomy
- Nurturance
- Dominance
- Exhibition
- Order
- Play
52Attribution Errors
- Fundamental Attribution Error (FAE) - The bias to
attribute behaviour to stable internal causes
rather than external ones
53FAE 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)
54Gilbert 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
55Self-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.
56Some 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.

58Social Identity Theory (Tajfel et al. 1979)
- Based on four interrelated concepts
- Social categorization
- Social identity
- Social comparison
- Positive distinctiveness
59Social 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
61Explain these concepts as they are expressed in
the film The Breakfast Club
62These 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
63Minimal 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.
64Stereotypes
- 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
65Formation of stereotypes
- Four theories of the structure and function of
stereotypes - Social-cognitive theories
- SIT
- Systems-justification theory
- Social representation theory
66Stereotype 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
67Stereotype 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.
68Stereotypes 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
69Stereotypes 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)
70Stereotypes 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.
71Origins 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.
72Biological 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
733 causes of hunger
- Brain regulation
- Blood sugar levels
- Hormones
74Brain 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
75Glucose 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
76Digestive 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.
77Hormonal 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
78What are the key environmental factors governing
eating?
- Learned preferences
- Food-related cues
- Stress
79How does classical conditioning play a role in
eating?
- Preferences in taste are learned through
associations created in classical conditioning.
80If 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.
81How 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.
82What 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.
83How 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.
84Define 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.
85What 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.
86How common is dieting?
- 24 of men and 40 of women diet
87Can 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.
88Define 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.
89Achievement 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.
90The 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.
91Affiliation
- Affiliation the need to associate with others
and maintain social bonds. - Also included the fear of rejection, jealousy,
and depression.
92TAT 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.

94Journal
- 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.

96Emotions
- There are 3 elements to emotional experience
- 1. subjective conscious experience (cognitive)
- 2. bodily arousal (physiological)
- 3. characteristic overt expression (behavioral)
97The 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
98The 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.
99Autonomic 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
100Brain Activity
- The emotional centers of the brain are the
- Hypothalamus
- Amygdala
- Limbic system
- The amygdala plays a central role in processing
emotional stimuli
101The 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.
102The 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
103Facial 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.
104Theories 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.
105Emotions
- Darwin emotions developed because of their
adaptive value. Emotions are innate reactions to
specific stimuli. They are recognizable without
thought.
106Innate 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.

108The Nature of Personality
- Personality is the consistent disposition to
behave a certain way in a variety of situations.
109Personality 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.
110Personality 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
111Psychodynamic 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.
112Freud proposed three components of personality
behaviour was the result of interactions between
these three parts.
113Id
- 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.
114Ego
- 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.
115Superego
- Superego the moral component that incorporates
social standards about right and wrong. It
emerges from the ego at approx. 3 to 5 years old.
116Freud 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.
117(No Transcript)
118Anxiety
- 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)
119Defense 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.
120Behavioural Perspectives
121Albert 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.
122Observational 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.
123Humanistic 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
124Carl 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
125Incongruence
- 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.
126Abraham 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.
