2September 11, 2001
- Four passenger planes hijacked by terrorists.
- Deliberately flew 3 of aircraft into US
buildings. - Killed 2,998 people.
- What were their motives?
3Motivation
- From Latin word movere move
- A need or desire that energizes and directs
behavior toward a goal - Biological, cognitive, clinical explanations
- Why do we do what we do?
4Historic Explanations Instinct(s)
- A complex, inherited, unlearned behavior that is
rigidly patterned throughout a species - William James listed 37 instincts.
- Includes mental ones
- Jealously, curiosity, and cleanliness
- Original psychological explanation of motivation.
- Problems
- Difficulty using instincts to both label and
explain behaviors - Theorists came up with more than 10,000
instincts.
5Historic Explanations Drives
- States of tension that result from internal
imbalance. - Prompt an organism to restore the balance,
typically reducing the drive - Ex skipping breakfast
- Come 1000am you are starving
- Creates a physiological need for food, leads to
hunger, a psychological drive.
6Drive-Reduction Theory
- The idea that a physiological need creates an
aroused tension state (a drive) that motivates an
organism to satisfy the need - Eating and drinking are examples of
drive-reducing behaviors.

10Biological Explanations Arousal TheoriesWhat
is the basic idea in
arousal theories of motivation? Is homeostasis
the same as drive reduction?
11Biological Explanations Arousal Theories
- Arousal
- Levels of alertness and responsiveness
- Lets look at 3 friends the night before the SAT
- A You know, I dont really care about the test.
Im going to a trade school, and Im only taking
the test b/c my parents want me to. Can I have
some of your fries? - B I want to do well, but if I screw up on this
test, its not going to permanently ruin my life.
Ill give it my best shot. Wheres the
ketchup? - C Its all on the line tomorrow. If I dont
get a good score, it will change my life forever.
Im so nervous, I cant eat. - Which one are you? Who will do better on the
test?
12Yerkes-Dodson Law
- The theory that a degree of psychological arousal
helps performance, but only up to a certain point - Optimum level of arousal depends on the
difficulty of the task. - Each person has an optimum level of stimulation
they like to maintain. - Which friend would perform best according to this
law? - Friend B
13Yerkes-Dodson Law
- Basically arousal will increase performance up to
a point. - Further arousal impairs performance.
- Optimal arousal changes with difficulty of a
task. - Simple task higher arousal higher performance.
- Difficult task lower arousal works best
- How does this relate to stress?
14Biological Explanations Homeostasis
- A tendency to maintain a balanced or constant
internal state - Ex Movie Bio-dome.
- The regulation of any aspect of body chemistry,
such as blood glucose, around a particular level - Any change in levels, up or down, results in
being motivated to bring the level back to
normal. - What is your homeostasis with body temp?

24Cognitive Explanations Intrinsic and Extrinsic
MotivationWhy is intrinsic motivation more
beneficial than extrinsic movtivation?
25Extrinsic Intrinsic Motivation Motivation
- A desire to perform a behavior because of
promised rewards or threats of punishment - Examples
- Home, work, school
- Do you study b/c you want an A or because you
want to learn the material?
- A desire to perform a behavior for its own sake
and to be effective - Do you participate in class for bonus cards or
b/c you just want to?
26Which is better?
- Intrinsic motivation often results in higher
achievement. - Behavior maintained by extrinsic motivation alone
may not be effectively sustained once the rewards
are removed. - Evidence says removal of an extrinsic motivator
may result in behavior levels even lower than
before the rewards were given. - Do you have any experiences that support these
statements? - Is everything about rewards and punishment?
- Do we have free will????
27Clinical Explanations Hierarchy of Needs
- Abraham Maslow (1908-1970)
- Humanistic psychologist who developed the
hierarchy of needs
28Hierarchy of Needs
- Maslows pyramid of human needs begins at the
base with physiological needs, and then proceeds
through safety needs to psychological needs. - Higher-level needs wont become active until
lower-level needs have been satisfied. - Self-Actualization
- According to Maslow, the need to live up to ones
fullest and unique potential

34Clinical Explanations Achievement
- Henry Murray (1893-1988)
- Neo-Freudian who first established the concept of
achievement motivation - Includes a desire for
- Significant accomplishment
- The mastery of things, people, or ideas
- Attaining a high standard
35 Clinical Explanations Motivating
Ourselves Motivating Others
- Cultivate intrinsic motivation
- Attend to individual motives
- Set specific, challenging goals
- Choose an appropriate leadership style
- Task leadership
- Social leadership
- Developing Self Motivation
- Associate your high achievement with positive
emotions - Connect your achievement with your efforts
- Raise your expectations
36Motivating Others (cont.)Task and Social
Leadership Leadership
- Goal-oriented leadership that sets standards,
organizes work, and focuses attention
- Group-oriented leadership that builds teamwork,
mediates conflict, and offers support

38A Closer Look the Physiology of Hunger
- Glucose
- Form of sugar which circulates through the body
- One feels hunger when the levels become low.
- Insulin
- Hormone which allows the body to use glucose for
energy or fat production - Insulin levels up glucose levels down.
- Leptin
- Protein produced by bloated fat cells
- Send a message to stop eating
- Orexin
- Hunger-triggering hormone
- Produced by the hypothalamus
- As glucose levels drop, orexin levels increase
and person feels hungry
39Hypothalamus set point theory
- Weight thermostat.
- Maintains a set point.
- Damage to this can lead to severe weight gain or
loss. - 1.) We have a Basal Metabolic Rate (resting rate
at which we burn calories for energy). - 2.) We have a specific number of fat cells (which
can expand in size and increase in ). - 3.) We have hormones that work together to keep
our weight where it is designed to be.
40Basal Metabolic Rate (BMR)
- The bodys resting rate of energy expenditure
-
- Set Point
- The point at which an individuals weight
thermostat is supposedly set. - When the body falls below this weight, increased
hunger and a lower basal metabolic rate (BMR) may
act to restore the lost weight.
41Set Point Might be a good idea to get this!
42Environment and Hunger
- External Incentives
- Include the sight, sound, and smell of food
- Cultural Influences on Eating
- Cultural views on obesity can vary
- Culture influences the foods we like and dislike.
43Eating DisordersWhy do people develop
eating disorders?
44Anorexia Nervosa
- An eating disorder in which normal weight people
suffer delusions of being overweight - Usually in adolescent females
- May put themselves on self-starvation regimens
- May become dangerously underweight
45Bulimia Nervosa
- An eating disorder characterized by episodes of
overeating - Usually overeat high calorie foods
- Overeating is followed by vomiting, using
laxatives, fasting, or excessive exercise
