Section 1
Instinct Theory
• William McDougall proposed that humans were motivated by a variety of instincts.
–
Instincts
are innate tendencies that determine behavior.
• William James proposed that humans have instincts such as cleanliness, curiosity, parental love, sociability, and sympathy.
Section 1

Section 1
Drive-Reduction Theory
• The thing that motivates us starts with a need that leads to a drive.
•
Need
•
Drive
Section 1
Drive-Reduction Theory
(cont.)
• Drive-reduction theory states that physiological needs drive an organism to act in either random or habitual ways.
• Biological needs drive an organism to act, and the organism strives to maintain
homeostasis
.
Section 1
Drive-Reduction Theory
(cont.)
• Clark Hull suggested that all human motives are extensions of basic biological needs.
• Harry Harlow and others doubted Hull and proved that other factors, such as pleasure, also play a role.
• They conducted experiments using baby monkeys and surrogate mothers.

Section 1
Cognitive Theory
• Cognitive psychologists seek to explain motivation by looking at forces inside and outside of us that energize us to move.
• According to them, we act in particular ways at particular times as a result of extrinsic and intrinsic motivations.
Section 1
Cognitive Theory
(cont.)
•
Extrinsic motivation
•
Intrinsic motivation
• Sometimes we engage in an activity because of both types of motivation.
• Overjustification effect: when people are given more extrinsic motivation than necessary to perform a task, their intrinsic motivation declines.

Section 2-Polling Question
Biological Motives
• Some behavior is determined by the internal, or physiological, state of the organism.
– The nervous system is constructed in such a way that dramatic variations in blood sugar, water, oxygen, salt, or essential vitamins lead to changes in behavior designed to return the body to a condition of chemical balance, or
homeostasis
.
Some Biological and Social Needs Section 2
Biological Motives
(cont.)
• Several of the drives that motivate behavior are homeostatic, such as hunger.
– Your body requires food to grow, repair itself, and to store reserves.
Section 2
Biological Motives
(cont.)
•
Lateral hypothalamus (LH)
•
Ventromedial hypothalamus (VMH)
• The glucostatic theory—the hypothalamus monitors the amount of glucose, or ready energy, available in the blood.
• Set-point—the weight around which your day-to-day weight tends to fluctuate.
Section 2
Biological Motives
(cont.)
• The hypothalamus interprets at least three kinds of information: – The amount of glucose entering the cells of your body.
– Your set-point.
– Your body temperature.
Section 2
Biological Motives
(cont.)
• Other factors tied to hunger: – Psychosocial hunger factors—external cues that can affect eating, such as where, when, and what we eat.
– Obesity—a genetic component may predispose some people to obesity.
Percentage of Overweight Americans Section 2
Biological Motives
(cont.)
• Stanley Schachter and his colleagues conducted studies to prove that overweight people respond to external cues, while normal-weight people respond to internal cures.
Section 2
Do you feel that you only eat when you are hungry, or that you are also affected by external cues?

Section 2
Social Motives
• Social motives are learned from our interactions with other people.
• The achievement motive concerns the desire to set challenging goals and to persist in trying to reach those goals despite obstacles, frustrations, and set backs.
Section 2
Social Motives
(cont.)
• David McClelland measured achievement motivation using the Thematic Apperception Test (TAT).
– 83% of the entrepreneurs scored high in achievement, but only 21% of the nonentrepreneurs scored that high.
Section 2
Social Motives
(cont.)
• Other people are motivated by a fear of failure.
– People display this fear when they choose easy tasks offering assured success or impossible tasks with no chance of success.
– They often find excuses to explain their poor performance.
Section 2
Social Motives
(cont.)
• Some people also have a fear of success.
– Matina Horner conducted a study showing that success involves deep conflicts for some people.
– Although, it is very difficult to define success or to tell whether a person who does not try something is afraid of success or failure.
Section 2
Social Motives
(cont.)
• Other theories: – J.W. Atkinson developed an
expectancy value theory
to explain goal-directed behavior.
– Competency theory—too easy a task or too difficult a task means we do not learn anything about how competent we are.
Your Performance Section 2
Social Motives
(cont.)
• Abraham Maslow believed that all human beings need to feel competent to win approval and recognition, and to sense that they have achieved something.
• He believed that some needs take precedence over others and that achieving one level of satisfaction releases new needs and motivations.
Maslow’s Hierarchy of Needs Section 2
Social Motives
(cont.)
• Maslow placed achievement motivation in the context of a hierarchy of needs: – Physiological needs (a
fundamental need
) – Safety needs (a fundamental need) – Belongingness and love needs (a
psychological need
) – Esteem needs (a psychological need) – The need to fulfill one’s potential (a
self-actualization need
) Section 2
Achieving goals, feeling competent, and gaining approval and recognition would all under which need in Maslow’s hierarchy?

Physiological needs

Section 3-Polling Question
Emotions
• We use the words
drive
or
motivation
to emphasize the needs, desires, and mental calculations that lead to goal-directed behavior.
• We use the words
emotion
or
affect
to stress the feelings associated with these decisions and activities.
Section 3
Emotions
(cont.)
• Emotional intelligence is the ability to perceive, imagine, and understand emotions and to use that information in decision making.

The Range of Emotions Section 3
Expressing Emotions
(cont.)
• Emotions result from four occurrences: – You must interpret some stimulus.
– You have a subjective feeling, such as fear or happiness.
– You experience physiological responses, such as an increased heart rate.
– You display observable behavior, such as smiling or crying.
Section 3
Expressing Emotions
(cont.)
• All emotions have three parts: – The physical—how the emotion affects the physical arousal of an individual.
– The behavioral—outward expression of the emotion, such as body language, hand gestures, and tone of voice.
– The cognitive—how we think about or interpret a situation, which affects our emotions.
Paul Ekman Section 3
Expressing Emotions
(cont.)
• Numerous studies have shown that certain basic facial expressions are innate —or part of our biological inheritance.
• Learning is also an important factor in emotional expression.
• James Averill believes that many of our everyday emotional reactions are the result of social expectations and consequences.

Some Biological and Social Needs
Whereas biological needs are physiological requirements critical to our survival, we acquire social needs through experience and learning.
Figure 1
Percentage of Overweight Americans
Overweight people face increased risk for heart disease, stroke, high blood pressure, clogged arteries, adult onset diabetes, and early death.
Figure 2
Your Performance
The Yerkes-Dodson law says that your performance on a task is an interaction between the level of physiological arousal and the difficulty of the task. So on difficult tasks, you do better if your arousal level is low.
Figure 3
Maslow’s Hierarchy of Needs
According to Maslow, only after satisfying the lower level of needs is a person free to progress to the ultimate need of self-actualization.
Figure 4
The Range of Emotions
Emotions are subjective feelings, so psychologists cannot agree on how many emotions exist or the exact impact of a specific emotion.
Figure 5
Threatening Elements
When people from various cultures were asked to identify the threatening shapes in each pair, they consistently selected the triangular and diagonal elements.
Figure 6
Theories of Emotion
These theories of emotion differ depending on the relationship of physiological change and cognitive interpretation of emotion.
Figure 7
Fear and Relief
According to the opponent-process theory, when the stimulus for one emotion is removed, you feel the opposite emotion.
Figure 8
Paul Ekman 1934 –
“The face is the primary site for the display of emotions. Together with the voice, it may tell the listener how the speaker feels about what is being said. . .” Profile
