Social Thinking

·  Social Thinking: how we think of one another

·  Attribution Theory: the idea that we give a casual explanation for someone's behavior, we credit that behavior either to the situation or the person's disposition

·   Fundamental Attribution Error: the tendency to underestimate the impact of a situation and overestimate the impact of a situation and overestimate the impact of personal disposition

·Attitudes: a belief of feeling that predisposes one to respond in a particular way to something 

· Foot-in-the-door Phenomenon: the tendency for people who have first agreed to a small request to comply later with a larger request

· Door-in-face Phenomenon: the tendency for people who say no to a huge request, to comply with a smaller one

·Cognitive Dissonance Theory: we do not like when we have either conflicting attitudes or when will our attitudes do not match our actions

-When they clash, we will change our attitude to create balance

· Group Polarization: the concept that a group's attitude is one of extremes and rarely moderate

·    Groupthink: the mode of thinking that occurs when the desire for harmony in a decision-making group overrides common sense 

·   Self-Fulfilling Prophecies: occurs when one person's belief about others leads one to act in ways that induce the others to appear to confirm the beliefs

Social Relations

·    Aggression: any physical or verbal behavior intended to hurt or destroy

·   The Psychology of Aggression:

·                     Reciprocity Norm: expectation that people will help those that will help them

·                     Social Responsibility: the expectation that people help those that depend on them

·                     5 Factors of Attraction:

1. Proximity: geographic nearness

·                     Mere Exposure Effect: repeated exposure to something breeds liking, mirror image concept

2. Reciprocal Liking: you are more likely to like someone who likes you

3. Similarity: opposites do not attract, similarity breeds concept

4. Physical Attractiveness

5. Love

·                     Passionate Love: an aroused state of intense positive absorption of another

· Social Exchange Theory: the idea that our social behavior is an exchange process, which we maximize benefits and minimize costs

· Peacemaking: give people super ordinate (shared) goals that can only be achieved through cooperation, win win situation through mediation, GRIT (Graduated and Reciprocated Initiatives in Tension Reduction)

Motivation and Emotion

·   Motivation: a need or desire that energizes and directs behavior

· \Instinct Theory: we are motivated by our inborn automated behavior, but instincts only explain why we do a small fraction of our behaviors

· Drive-Reduction Theory: the idea that a physiological need creates an aroused tension state (a drive) that motivates an organism to satisfy the need

-The need is usually to maintain homeostasis

-We are not only pushed by our needs but pulled by our incentives: a positive or negative environmental stimulus that motivates behavior

Maslow's Hierarchy of Needs

·                     Maslow said we are motivated by needs, and all needs are not created equal, we are driven to satisfy the lower level needs first.

Hunger

·                     Hunger: both physiological ad psychological 

·                     Biological Basis of Hunger

-Hunger does not come from our stomach

-Comes from the brain: the hypothalamus

·                     Hypothalamus

1. Lateral Hypothalamus 

-When stimulated it makes you hungry

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

2. Ventromedial Hypothalamus

-When stimulated you feel full

-When lesioned you will never feel full again

·                     Two Theories

1.                   Leptin: is a protein produced by bloated fat cells

2.                  Set Point: 

·                     Hypothalamus acts like a thermostat

·                     We are meant to be in a certain weight rage

·                     When we fall below weight our body will increase hunger and decrease energy expenditure (Basic Metabolic Rate)

·    Body Chemistry 

-Glucose: the hormone insulin converts glucose to fat, when glucose levels drop-hunger increases

· Hypothalamus and Hormones 

-The hypothalamus monitors a number of hormones that are related to hunger

·The Psychology of Hunger

-External: people whose eating is triggered more by the presence of food than internal factors

· Eating Disorder

-Bulimia Nervosa: characterized by binging (eating large amounts of food) and purging (getting rid of food)

-Anorexia Nervosa: starve themselves to below 85% of their normal body weight, see themselves as fat, majority are woman
