Motivation & Emotion
AP Psychology
Chapter 10
Emotion
• Organized psychological and physiological
reactions to changes in one’s relationship to the
world.
▫
▫
▫
▫
▫
▫
Transitory (not constant)
Either positive or negative
Dependent on cognitive appraisal of a situation
Alter thought processes
Create tendency towards certain actions
Passions (not actions) because they occur whether
you want them to or not
The Brain’s Role in Emotion
• Activity in the limbic system is important to the
experience of emotion
• Control over emotional and nonemotional facial
expressions.
• Hemispheric Differences – right hemisphere is
more active in experiencing positive emotions

Theories of Emotion
• Does your heart pound because you are
afraid….or are you afraid because you feel your
heart pounding?
James-Lange
Theory of Emotion
• We feel emotion because of biological changes
caused by stress
Sight of
oncoming
car
(perception of
stimulus)
Pounding
heart
(arousal)
Fear
(emotion)
Cannon-Bard
Theory of Emotion
 Emotion-arousing
stimuli simultaneously
trigger:
 physiological
responses
 Emotion
 Thalamus sends
signals to the cortex
and to our autonomic
nervous system at the
same time
Sight of
oncoming
car
(perception of
stimulus)
Pounding
heart
(arousal)
Fear
(emotion)
Schachter’s Two-Factor Theory
of physical
 Both our
responses and our
Emotion
Pounding

(arousal)

Fear
(emotion)
Cognitive
label
“I’m afraid”
cognitive labels
(mental
representations)
combine to cause
an emotional
response
 Emotion
depends on 2
factors:
1. Biology
2. Cognition
Emotion- Lie Detectors
 Polygraph
 machine commonly used in attempts to
detect lies
 measures several of the physiological
responses accompanying emotion
 perspiration
 cardiovascular
 breathing changes
Emotion-Lie Detectors
 Control Question
 Up to age 18, did you ever physically
harm anyone?
 Relevant Question
 Did [the deceased] threaten to harm you
in any way?
 Relevant > Control --> Lie

Communicating Emotion
• Facial movements and expressions – primary
role
▫ Body cues and tone of voice play smaller role
• Cultural affect on ways in which emotions are
expressed –
▫ Japanese and North American people disagreed
about which faces showed anger, disgust, and fear
• Social referencing – people use another’s
emotional state to determine how to react
Culturally universal expressions
Infants’ naturally occurring emotions
What Is Motivation?
• Factors that influence the initiation, direction,
intensity, and persistence of behavior.
• Motives – act as intervening variables – provide
a single reason for the occurrence of behaviors
• Sources of motivation:
▫
▫
▫
▫
Biological
Emotional
Cognitive
Social
Drive Reduction Theory
• Primary and secondary drives reduce
biological needs caused by an imbalance in
homeostasis
• the idea that a physiological need creates an
aroused tension state (a drive) that
motivates an organism to satisfy the need
• Need – a requirement for survival
• Drive – our impulse to act in a way that
satisfies the need

and Homeostasis

(e.g., for
food, water)
Drive
(hunger, thirst)
Drive-reducing
behaviors
(eating, drinking)
Arousal Theory
• People are motivated to
maintain their optimal level of
arousal
▫ Increase arousal when it is too
low
▫ Decrease arousal when it is
too high
• Regulation of arousal
• Yerkes-Dodson Law – performance
at any task varies with arousal. At low
arousal, people are lethargic and
perform badly. As arousal increases,
performance also increases - but only to
a point, after which increasing arousal
actually decreases performance.
Opponent-Process Theory
• People are usually at a normal, baseline state
• We perform acts that move us from our baseline
state, which are initially pleasurable
• Eventually, we feel an opponent process, or
motivation to return to our baseline, neutral
state
• Common with addictions – smoking, drinking,
etc.
Incentive Theory
• Behavior is goalorientated
• We behave in ways that
allow us to attain
desirable stimuli and
avoid negative stimuli
• We are motivated to
seek rewards
3 Types of Motivation:
• Hunger
• Sexual
• Achievement
Hunger Motivation
• Biological signals for hunger and satiety:
 Signals from stomach
 Signals from the blood
• Hypothalamus – monitors and controls body
chemistry – makes us feel hungry
▫ Hypothalamus is involved in the homeostatic
maintenance of a set point
• Ventromedial nucleus of the hypothalamus –
stop eating
• Lateral hypothalamus – “hunger center” – start
eating
Hunger Motivation – Psychological
Factors
• Nonbiological factors can override the brain’s
regulatory processes.
• Externals – motivated to eat by external food
cues (attractiveness or availability of food)
• Internals – less affected by the presence and
presentation of food
• Garcia Effect – occurs whenever nausea is paired
with food or drink (classical conditioning – taste
aversion)
• Culture & background
Eating Disorders: Obesity
• Overweight by 100+ pounds
• Possible Causes:
▫ Inadequate physical activity and overeating
▫ Genetic predisposition
▫ Psychological explanations
• Losing Weight
▫
▫
▫
▫
Diet
Surgery
Antiobesity medications
Exercise
Eating Disorders: Anorexia Nervosa
• Characterized by behaviors resulting in weight
loss below 85% of normal.
▫ About 95% of sufferers are young females.
▫ Despite hunger, refusal to eat.
• Causes serious, often irreversible physical
damage.
Women’s Body Images
Eating Disorders: Bulimia Nervosa
• Intense fear of being fat, but may be thin,
normal in weight, or even overweight.
• Characterized by “binge-purge” episodes.
• episodes of overeating, usually of high-calorie foods,
followed by vomiting, laxative use, fasting, or excessive
exercise
• Majority of sufferers are women
• Weight of a bulimic is normal or slightly above
average
Sexual Motivation
• Sex
▫ a physiologically based motive, like hunger, but it
is more affected by learning and values
• Factors affecting sexual motivation and behavior
include:
▫ Individual’s physiology.
▫ Learned behavior.
▫ The physical and social environment.
Sexual Orientation
• Nature of a person’s enduring emotional,
romantic, or sexual attraction to others.
• In many cultures, heterosexual is a moral norm.
▫ Homosexuality seen as a disease, a mental
disorder, or a crime.
• Attempts to alter sexual orientation of
homosexuals usually ineffective.
Achievement Motivation
• Extrinsic vs. Intrinsic Motivation
• Much of our behavior is motivated by a desire
for esteem.
• Need for Achievement – motivated to master
tasks – raise the bar high
▫ Individual differences – high need to achieve vs.
low need to achieve
Development of Achievement
Motivation
• Tends to be learned, especially during early
childhood.
• Parental Influences
• Cultural Influences
• Effects of Beliefs About Oneself
Goal Setting and Achievement
Motivation
• Goals established to reduce a discrepancy
between current and desired situation.
• In general, the more difficult the goal, the harder
one will try to reach it.
▫ Goal must be attainable and valued.
• Important to set clear and specific goals.
Achievement and Success in
the Workplace
• Low motivation when one feels they have little or
no control over work environment.
• Ability to set and achieve clear goals can increase
job performance and satisfaction.
• Especially effective goals are:
▫ Personally meaningful.
▫ Specific and concrete.
▫ If supported by management.
Achievement in the Workplace
 Theory X
 assumes that workers are basically lazy, errorprone, and extrinsically motivated by money
 workers should be directed from above
 Theory Y
 assumes that, given challenge and freedom,
workers are motivated to achieve self-esteem and
to demonstrate their competence and creativity
Achievement and Subjective
Well-Being
• Subjective well-being is feeling satisfied with life,
often having positive emotions
• Subjective well-being tends to be relatively
stable through life.
▫ Baseline level may be influenced by genetics.
• What generates happiness?
▫ Close Social Ties
▫ Religious Faith
▫ Having necessary resources to allow progress
toward one’s goals.
Maslow’s Hierarchy of Needs
 begins at the base with
physiological needs that must
first be satisfied
 then higher-level safety needs
become active
 then psychological needs
become active
Conflicting Motives & Stress
• Four basic types of motivational conflicts:
▫
▫
▫
▫
Approach-approach
Avoidance-avoidance
Approach-avoidance
Multiple approach-avoidance
• Conflicts can create significant stress.
