What Is Emotion?

Emotion – A four-part process consisting of physiological arousal, cognitive interpretation, subjective feelings, and behavioral expression

Copyright © Allyn & Bacon 2007

What Do Our Emotions Do For Us?

Emotions have evolved to help us respond to important situations and to convey our intentions to others

Copyright © Allyn & Bacon 2007

The Evolution of Emotions Emotions have survival value and have been shaped by natural selection Individuals vary tremendously in emotional responsiveness Emotions are not entirely programmed by genetics

Copyright © Allyn & Bacon 2007

Cultural Universals in Emotional Expression People everywhere can recognize at least seven basic emotions: sadness, fear, anger, disgust, contempt, happiness and surprise There are, however, huge cultural differences in the context and intensity of emotional displays

Copyright © Allyn & Bacon 2007

Cultural Universals in Emotional Expression

Display rules – Permissible ways of displaying emotions in a particular society

Where Do Our Emotions Come From? The discovery of two distinct brain pathways for emotional arousal has clarified the connections among the many biological structures involved in emotion and has offered solutions to many of the longstanding issues in the psychology of emotion Copyright © Allyn & Bacon 2007

The Neuroscience of Emotion The biological mechanisms at work behind our emotions include: • • • • •

The limbic system The reticular formation The cerebral cortex The autonomic nervous system Hormones

Copyright © Allyn & Bacon 2007

Psychological Theories of Emotion James-Lange theory– An emotion-provoking stimulus produces a physical response that, in turn, produces an emotion

Cannon-Bard theory – An emotional feeling and an internal physiological response occur at the same time • One is not the cause of the other • Both the result of a cognitive appraisal of the situation Copyright © Allyn & Bacon 2007

Psychological Theories of Emotion

Two-factor theory of emotion – Emotion results from the cognitive appraisal of both (1) physical arousal and (2) emotion provoking stimulus

Psychological Theories of Emotion Cognitive appraisal theory – Theory that individuals decide on an appropriate emotion following the event Opponent-process theory – Theory that emotions have pairs; when one is triggered the other is suppressed

Copyright © Allyn & Bacon 2007

Arousal, Performance, and the Inverted “U” Inverted “U” function – Describes the relationship between arousal and performance; both low and high levels of arousal produce lower performance than does a moderate level of arousal High

Performance Low

Low High Arousal Level Copyright © Allyn & Bacon 2007

Arousal, Performance, and the Inverted “U”

Sensation seekers – Individuals who have a biological need for higher levels of stimulation than do other people

How Much Control Do We Have Over Our Emotions?

Although emotional responses are not always consciously regulated, we can learn to control them

Copyright © Allyn & Bacon 2007

Developing Emotional Intelligence

Emotional intelligence – Ability to understand and control emotional responses Emotional control can be achieved by learning

Copyright © Allyn & Bacon 2007

Detecting Deception People can also control their emotions to deceive Do “lie detectors” really work?

Polygraph – Device that records the graphs of many measures of physical arousal; often called a “lie detector” really an arousal detector Copyright © Allyn & Bacon 2007

Motivation: What Makes Us Act as We Do?

Motivation takes many forms, but all involve inferred mental processes that select and direct our behavior

Copyright © Allyn & Bacon 2007

Motivation: What Makes Us Act as We Do?

Motivation – All processes involved in starting, directing, and maintaining physical and psychological activities

Copyright © Allyn & Bacon 2007

How Psychologists Use the Concept of Motivation Motivation • Connects observable behavior to internal states • Accounts for variability in behavior • Explains perseverance despite adversity • Relates biology to behavior

Copyright © Allyn & Bacon 2007

Types of Motivation Drive – Biologically instigated motivation Motive – Internal mechanism that directs behavior (often used to describe motivations that are learned, rather than biologically based)

Copyright © Allyn & Bacon 2007

Types of Motivation Intrinsic motivation – Desire to engage in an activity for its own sake Extrinsic motivation – Desire to engage in an activity to achieve an external consequence (e.g. a reward)

Copyright © Allyn & Bacon 2007

Achievement Motivation What motivates us to work?

(School, job, sports, video games, relationships etc..)

Intrinsic Motivators

Extrinsic Motivators

Rewards we get internally, such as enjoyment or satisfaction.

Reward that we get for accomplishments from outside ourselves (grades or money or etc..) Work great in the short run.

Types of Motivation Conscious motivation – Having the desire to engage in an activity and being aware of the desire Unconscious motivation – Having a desire to engage in an activity but being consciously unaware of the desire

Copyright © Allyn & Bacon 2007

Theories of Motivation Instinct theory – View that certain behaviors are determined by innate factors Fixed-action patterns – Genetically based behaviors, seen across a species, that can be set off by a specific stimulus

Copyright © Allyn & Bacon 2007

Theories of Motivation Drive theory – View that a biological need (an imbalance that threatens survival) produces drive Homeostasis – The body’s tendency to maintain a biologically balanced condition

Copyright © Allyn & Bacon 2007

Theories of Motivation

Locus of control – An individual’s sense of where his or her life influences originate–internally or externally

Copyright © Allyn & Bacon 2007

Maslow’s Humanistic Theory Hierarchy of needs – The notion that needs occur in priority order, with the biological needs as the most basic

Copyright © Allyn & Bacon 2007

Management Theory

Management/Teaching styles relate closely to Intrinsic/Extrinsic Motivators.

Theory X Managers believes that employees will work only if rewarded with benefits or threatened with punishment. Think employees are Extrinsically Motivated. Only interested in Maslow’s lower needs.

Theory Y Managers believe that employees are internally motivated to do good work and policies should encourage this internal motive. Interested in Maslow’s higher needs.

Rewards Can Sometimes Squelch Motivation Overjustification – The process by which extrinsic rewards can sometimes displace internal motivation, as when a child receives money for playing video games

Copyright © Allyn & Bacon 2007

How Are Achievement, Hunger, and Sex Alike? Different? No single theory accounts for all forms of motivation, because each motive involves its own mix of biological, mental, behavioral, and social/cultural influences Copyright © Allyn & Bacon 2007

Measuring the Need for Achievement Projection – Process by which people attribute their own unconscious motives to other people or objects

Need for achievement (n Ach) – Mental state that produces a psychological motive to excel or reach some goal

Copyright © Allyn & Bacon 2007

A Cross-Cultural Perspective on Achievement Individualism – View that places a high value on individual achievement and distinction Collectivism – View that values group loyalty and pride over individual distinction

Copyright © Allyn & Bacon 2007

Hunger Motivation The multiple-systems approach to hunger Set point – Refers to the tendency of the body to maintain a certain level of body fat and body weight

Weight control is a complex issue with no simple answers

Copyright © Allyn & Bacon 2007

Biological Basis of Hunger Hunger does NOT come from our stomach. It comes from our…

Brain What part of the brain?

The Hypothalamus

Hypothalamus Lateral Hypothalamus

Ventromedial Hypothalamus

When stimulated it makes you hungry.

When stimulated you feel full.

When lesioned (destroyed) you will never be hungry again.

When lesioned you will never feel full again.

Thirst and Pain

Volumetric thirst – A drop in extracellular fluid levels Osmotic thirst – A drop in intracellular fluid levels

Sexual Motivation Sex is natural. Without sex, none of us would be here. How do scientists (or you) find out about sex? YOU ASK!!!!!!

The Scientific Study of Sexuality Kinsey interviewed 18,000 Americans concerning their sexual behavior Masters and Johnson Sexual response cycle – Four-stage sequence of arousal, plateau, orgasm, and resolution occurring in both men and women

Copyright © Allyn & Bacon 2007

Kinsey’s Studies •Confidential interviews with 18,000 people (in early 1950’s). •Sexual Behavior in the Human Male and Sexual Behavior in the Human Female •Scale of sexuality….0 to 6 where 0 is exclusively heterosexual and 6 homosexual and 7 is asexual.

Click on Kinsey to see the movie trailer.

Masters and Johnson Study Click on Masters and Johnson to see a more detailed explanation of their research.

In the 1960’s William Masters and Virginia Johnson set out to explore the physiology of sex. 382 females and 312 males. After their research was done they ran an institute that claimed to turn homosexual people straight.

Phases of Human Sexual Response

Copyright © Allyn & Bacon 2007

Sexual Motivation Virtually any stimulus that becomes associated with genital touch and orgasm can become a conditioned stimulus that motivates sexual activity Sexual scripts – Socially learned ways of responding in sexual situations

Both learning and genetics affect our sexual behaviors Copyright © Allyn & Bacon 2007

We have discussed the energizing of sexual motivation but have yet to discuss its direction: Sexual Orientation An enduring sexual attraction toward members of either one's own gender or the other gender.

How is Sexual Orientation Determined There has been NO evidence that sexuality is socially determined. Kids raised by homosexual parents are no more likely to be homosexual that if they were raised by heterosexual parents. Thus it is likely biologically determined.

Motives in Conflict Approach-approach conflict – A conflict in which one must choose between two equally attractive options Approach-avoidance conflict – A conflict in which there are both appealing and negative aspects to the decision to be made

Copyright © Allyn & Bacon 2007

Motives in Conflict Avoidance-avoidance conflict – A conflict in which one must choose between two equally unattractive options Multiple approach-avoidance conflict – A conflict in which one must choose between options that have both many attractive and many negative aspects

How and Why Do We Experience Stress?

The human stress response to perceived threat activates thoughts, feelings, behaviors, and physiological arousal that normally promote adaptation and survival

Copyright © Allyn & Bacon 2007

Resistance

– the body – the body seems to adapt mobilizes it’s to the resources to presence of cope with a the stressor stressor Level of normal resistance

Alarm Reaction

Exhaustion – the body depletes it’s resources
