Title: Chapter 12 Motivation and Emotion
1Chapter 12 Motivation and Emotion
2Motivation
- Motivation Dynamics of behavior that initiate,
sustain, direct, and terminate actions - How motivated activities work
- Need Internal deficiency (running low on
something your body needs i.e. food) causes
drive - Drive Energized motivational state (e.g.,
hunger, thirst) activates a response - Response Action or series of actions designed to
attain a goal (driving to McDonald's to get some
food). - Goal Target of motivated behavior( getting some
food).
3Is there more to it?
- The model we discussed is simplistic because
- It dose not explain the behavior that takes place
after our needs are satisfied (think about over
eating at Thanksgiving) - It does not explain the behaviors that dont seem
to be related to satisfying an internal need such
as the drive for success and status( wanting a
Ferrari instead of a geo).
4What else is involved in behavior other than the
motivation
- The answer is the incentive value of the goal
which is defined as Goals appeal beyond its
ability to fill a need. - This is why we go after goals that have no
obvious effect on our internal needs like having
second helping of dessert even though we are full
(after our internal need is satisfied).
5Types of Motives
- Primary Motives Innate (inborn) motives based on
biological needs that must be met to survive
(hunger, thirst, air, pain avoidance) - Stimulus Motives Needs for stimulation and
information appear to be innate, but not
necessary for survival such as curiosity, the
need for exploration, and the need for physical
contact (I believe that its necessary for
survival). - Secondary Motives Based on learned needs,
drives, and goals. They are usually created
through the process of socialization to fulfil
needs for having power, status, and affiliation.
Example creating a myspace account, winning the
Super Bowl.
6Primary Motivation and Homeostasis
- Q Why do we have primary motivations?
- A To maintain the body Homeostasis.
- Homeostasis is a Steady state of body
equilibrium balance. - When the body is at the homeostasis level
everything the body needs is at the level for
ideal performance. In other words the body has
the right temperature, blood sugar, water, etc...
for you to perform your best. - When the homeostasis is disturbed, meaning you
body is getting low on sugar or is having too
much sugar, or getting to hot or to cold, your
body responds through primary motivation to get
the body back to the ideal level of functioning.
7Primary Motives Hunger
- How do you know that you are hungry?
- Hunger and the need to feed is influenced mainly
by the blood sugar level in your body. - When Hypoglycemia Low blood sugar is detected
through the stomach and the liver. A message is
sent to the brain to initiate a response to
restore the body homeostasis. - The Hypothalamus Brain structure regulates many
aspects of motivation and emotion, including
hunger, thirst, and sexual behavior. - The Feeding System Area in the lateral
hypothalamus, initiates eating when stimulated. - After the the blood sugar level is restored, the
Satiety System Area in the hypothalamus
terminates the eating behavior. - Damage to the feeding and satiety system can lead
do dramatic effects (not wanting to eat despite
hunger and not being able to stop eating despite
being full)
8More on Eating Behavior
- It takes 10 minutes for you brain to get the
message from your intestine to know that you are
no longer hungry (this why its recommended to eat
slow) - Aside from the daily level of blood sugar in your
body, hunger is influenced by the Set Point
Proportion of body fat that is maintained by
changes in hunger and eating point where weight
stays the same when you make no effort to gain or
lose weight. - Think of the set point as a memory foam mattress
(this why your weight stays the same even when
you are trying to diet).

10The Final Word on Eating Behavior Obesity and
Eating Disorders
- Why do we over eat?
- External Eating Cues Signs and signals linked
with food (advertisements) - Socialization and cultural factors.
- Comfort eating .
- Time and money
- Not wanting to waste food.
- Addictive qualities.
- Poor nutritional knowledge.
- Q How do we fix it?
- A Behavioral Dieting Weight reduction based on
changing exercise and eating habits and not on
temporary self-starvation. - Steps in Behavioral Dieting
- Observe yourself, keep an eating diary, and keep
a chart of daily progress. - Eat based on hunger, not on taste or learned
habits that tell you to always clean your plate - Avoid snacks
- Learn to weaken personal eating cues (dont eat
while you watch TV)
11Eating Disorders Anorexia Nervosa
- Anorexia Nervosa Active self-starvation or
sustained loss of appetite that is caused by
psychological conflicts. - It is related to control issues.
- It is very difficult to effectively treat
- Overwhelmingly affects adolescent females
12Eating Disorders Bulimia Nervosa (Binge-Purge
Syndrome)
- Bulimia Nervosa Excessive eating (gorging)
usually followed by self-induced vomiting and/or
taking laxatives - It is difficult to treat
- Prozac and Zoloft approved by FDA to treat
bulimia nervosa - Affects females overwhelmingly
13Causes of Anorexia Nervosa and Bulimia Nervosa
- Anorectics and bulimics have exaggerated fears of
becoming fat they think they are fat when the
opposite is true. - Bulimics are obsessed with food and weight
anorectics with perfect control - Anorectics will often be put on a weight-gain
diet to restore weight - Treat with cognitive-behavioral techniques
14Primary motivations Thirst
- Types of thirst
- Extracellular Thirst When water is lost from
fluids surrounding the cells of the body - Intracellular Thirst When fluid is drawn out of
cells because of increased concentration of salts
and minerals outside the cell.
15Primary motivations Pain Avoidance
- How is pain avoidance different than other drives
like hunger, thirst, etc...? - Its not a constant motivation it happens in
episodes. Episodic drive Occurs in distinct
episodes when bodily damage takes place or is
about to occur - In other motivation like hunger and thirst we are
seeking stimuli with pain we are running away
from the stimuli.
16Sex Drive
- Some argue that sex is not a primary motivation
because its not required for the individual
survival (your thoughts) - In lower animals sex drive is mainly influenced
by the fertility cycles and hormone levels - Estrus Changes in animals that create a desire
for sex Hormonal readiness for copulation.
being in heat. - Types Of sex Hormones
- Estrogen A female sex hormone
- Androgens Male hormones
17Sex Drive in humans
- In humans, sex drive is
- Non-homeostatic Drive Independent of bodily need
states or physical deprivation cycles. In other
words there are no internal cues that trigger the
body to engage in sex. The sex drive can be
triggered at any time and any setting. - Sex drive is weakly influenced by hormones.
Sexual expression is related to cultural,
emotional, and mental factors rather than
biological ones. (i.e. there is no connection
between the women menstrual cycle and the level
of sexual activity).
18Stimulus motivations
- These motivations reflect needs for information,
exploration, manipulation, and sensory input. - The purpose of the stimuli drive is to satisfy
our need of maintaining a homeostatic level of
arousal. - Arousal Activation of the body and nervous
system, watching movies, playing a video game,
making music, drawing a picture, etc... - In other words, stimuli drive are the things we
do to help us from being over stimulated or under
stimulated (boredom).
19Arousal Theory
- Arousal Theory Assumes people prefer to maintain
ideal, or comfortable, levels of arousal. - What is the ideal level of arousal required for
optimal performance? - The answer is explained through Yerkes-Dodsen
Law If a task is simple (the goal is simple such
as run fast from point A to B, it is best for
arousal to be high (sprinting) if it is complex
(playing basketball which involves a lot of
strategy, decision making, and concentration),
lower levels of arousal provides for the best
performance. - Q Does every one seek the same level of arousal?
- A No, Some people tend to seek high levels of
arousal such as extreme sports. Loud stimuli.
Others tend to seek lower levels of arousal such
as living in the country, reading a book, playing
chess. (

21Test Anxiety
- Test Anxiety High levels of arousal and worry
that seriously impair test performance. - How to Cope With Test Anxiety?
- Preparation do the work
- Relaxation learn to relax
- Rehearsal imagine the obstacle you may face and
how to go about handling it - Restructuring thoughts identify negative
irrational thoughts and challenge them
22Learned Motives
- Social Motives Acquired by growing up in a
particular society or culture. Its important to
have a nice car, or its crucial that you get
married before age 30. - What are the needs fulfilled by learned
motivations? - Need for Achievement Desire to meet some
internal standard of excellence or to excel - Need for Power Desire to have social impact or
control over others.
23Humanistic view of Motivation Abraham Maslow and
Needs
- Maslow organized Human Needs in a hierarchy based
on presumed strength or potency of those needs. - He believed that some needs are more powerful
than others and thus will influence your behavior
to a greater degree.
24Maslows Needs
- Basic Needs First four levels of needs in
Maslows hierarchy - Lower needs tend to be more potent (prepotent)
than higher needs - Love and belonging
- Need for esteem and self-esteem
- Growth Needs Higher-level needs associated with
self-actualization - Meta-Needs Needs associated with impulses for
self-actualization

26Other ways of categorizing motivations
- Types of Motivation
- Intrinsic Motivation Motivation coming from
within, not from external rewards based on
personal enjoyment of a task or activity (being
in this class for the sake of learning, not for a
grade or to fulfill requirements). - Extrinsic Motivation Based on obvious external
rewards, obligations, or similar factors (to get
the grade and fulfill a requirement).
27Emotions
- Emotion It is a state characterized by
physiological arousal and changes in facial
expressions, gestures, posture, and subjective
feelings. - Q What role do emotions play in our life?
- A they motivate a lot of our of behaviors
- Q What functions do emotions serve?
- A Survival and adaptation fear, love,
communication
28Th anatomy of Emotions
- There are two different layers of emotion inward
layer and outward layer. - Physiological Changes Inward layer (in emotions)
Include heart rate, blood pressure, perspiration,
and other involuntary responses - Emotional Expression (outward layer) Outward
signs of what a person is feeling
29Feeling v.s mood
- Feeling is the present emotional expense. (I am
feeling sad right now). It lasts for short
moments. - Mood Low-intensity, long-lasting emotional state
(I am depressed most of the time. It lasts hours,
days, months).
30Classification of emotions
- Emotion is classified in eight primary ones and
large numbers of other emotions that are caused
by a mixture of the primary ones - The primary emotions are
- Fear
- Surprise
- Sadness
- Disgust
- Anger
- Anticipation
- Joy
- Trust
31Example of non primary emotions
- Joy fear guilt
- love anger fear Jealousy
- Trust fear Submission
- Joy anticipation optimism

33Emotion and Brain
- Facts
- Positive emotions are processed by the left side
of the brain and negative emotions are processed
by the right side of the brain. This is why you
can feel happy and sad a the same time. This is
also why your right side is more ticklish tan
your left side. - The emotion of fear is regulated by Amygdala
Part of limbic system that produces fear
responses. This because fear is essential for
survival the response is process by the amyglada
directly without involving the brain. This why we
react without thinking.
34Emotions and physiology
- Emotion has an effect on the Automatic Nervous
system. Think about fear. - Parasympathetic Rebound Overreaction of the
Parasympathetic Branch to intense emotion, can
cause sudden death. The body over does the
slowing down of the heart rate to a stop.
35Lie Detectors
- Polygraph Device that records changes in heart
rate, blood pressure, respiration, and galvanic
skin response (GSR) Measures sweating. - It starts by asking the person neutral questions
to establish a base line reading then the person
is asked about the information the person is
suspected of lying about. The drastic difference
in the reading from the baseline is interpreted
as telling a lie. - The lie detector is not real. Its more of an
emotional state detector rather than a lie
detector. Baseline reading reflects the
relaxation state while the lie reading reflects a
state of anxiety and stress.
36Questions Asked While Taking a Polygraph
- Irrelevant Questions Neutral, nonthreatening,
non-emotional questions in a polygraph test - Relevant Questions Questions to which only
someone guilty should react - Control Questions Questions that almost always
provoke anxiety in a polygraph (e.g. Have you
ever taken any office supplies?)
37Emotion in the social cultural perspective.
- The expression of emotion has an adaptive value
bearing the teeth is a signal of one wanting to
be left alone - Basic facial expressions are universal and inborn
rather than learned (blind studies) - Culture plays a role in determining what emotions
are appropriate to express outwardly - individualistic culture where autonomy and
independence is valued, anger is a natural
accepted expression - collective cultures where harmony with community
and cooperation is emphasized expression of anger
outwardly is frowned upon. - Gender and emotion women are not more emotional
than men. Women are socialized to express
sadness, love, guilt, shame. While men are
socialized to only express anger and hostility.
Power v.s nurture.
38Body Language (Kinesics)
- Kinesics Is the Study of communication through
body movement, posture, gestures, and facial
expressions. - Its often used to convey or withhold emotional
messages. It could be both conscious and
unconscious. - It should be considered within the cultural
context.
39Three Types of Facial Expressions
- Our faces are capable of producing 20000
expression but there are three basic categories - Pleasantness-Unpleasantness
- Attention-Rejection
- Activation Degree of arousal a person is
experiencing
40Can we Detect Lies through body language?
- Usually shifty eyes, and nervously touching ones
body is associated with lying, but that is not
reliable measures. - Reliable body movement that can be indicative of
deception - Illustrators Gestures people use to illustrate
what they are saying - Tend to decrease when person is lying
- Emblems Gestures that have widely understood
meanings within a particular culture - Tend to increase when person is lying
41Theories of Emotion
42James-Lange Theory
- Emotional feelings follow bodily arousal and come
from awareness of such arousal. - You dont realize that you are afraid until you
notice the physiological changes associated with
the emotion of fear.
43Cannon-Bard Theory
- The thalamus (in brain) causes emotional feelings
and bodily arousal at the same time. - The physiological response and the feeling of
fear takes place at the same time
44Schachters Cognitive Theory
- Emotions occur when physical arousal is labeled
or interpreted on the basis of experience and
situational cues. - You experience the emotion after you cognitively
decide how you should label what you have
experienced.
45Facial Feedback Hypothesis
- Sensations from facial expressions and becoming
aware of them is what leads to emotional
experience. - Your facial expression tells you what you are
feeling. - Making different emotional faces produces
different physiological responses.
