244598101Batson's Empathy-altruism Modelin situations where others may need help, people might feel distress or might feel empathy. These states are important because either can cause a helping behavior. Some people disagree saying helping behavior only occurs when there is a benefit to the person offering help. Batson found that people who reported more distress than empathy tended to leave. However people who reported more empathy were more willing to help the subject.5

244598129Mere Exposure HypothesisRobert Zajonc's concept that repeated exposure to a stimulus leads to enhanced liking for it.33
244598130Minimal Justification EffectWhen a behavior can be justified by external rewards there is no need to change internal cognitions. However when the external justification is minimum you will need to decrease your dissonance by changing internal cognitions (e.g. from thinking that the task was boring to it wasn't too bad).34
244598131Autokinetic effectIf you stare at a point of light in a dark light, it will appear to move.35
244598132Need ComplementarityPeople choose relationships so that they can satisfy each other's needs.36
244598133Norman TriplettDid the first study of social psychology, people perform better on familiar tasks when in the presence of others than alone.37
244598134Over-Justification EffectIf you reward people for something they already like, they may stop doing it because they will start attributing their behavior to the reward.38
244598135Petty and Cacioppo's Elaboration Likelihood Model of PersuationThere are two routes to persuasion, central route (strong argument matters) and peripheral route (persuader's status and surroundings matter more than the argument).39

244598150Social PerceptionThe ways in which we form impressions about the characteristics of individuals and of groups of people.54
244598151Spatial ProximityPeople near to us are easily accessible and there is greater interaction which causes more affiliation.55
244598152Stanley Milgram's Obedience ExperimentStudy in which subjects were asked to administer electrical shocks to another person at higher and higher voltages. The majority of subjects yielded to the experimenter's request and continued shocking to the maximum voltage.56
244598153Stanley Schachter's ResearchThe greater the need to compare the greater is the desire to affiliate. Also greater anxiety does lead to greater desire to affiliate. A situation that provokes lesser anxiety doesn't provoke the need to affiliate. Anxious people like the company of anxious people. Both anxiety and a need to compare oneself with other people may play roles in determining both when and whom we affiliate with.57
244598154Theodore Newcomb's StudyExperiment that studied the influence of group norms in a small liberal college. The student's parents were republican and conservative. But the students became liberal with time and stayed that way 20 years after. Those who didn't marry liberal men changed back to old beliefs.58

244598158VerplankBelieved that social approval influences behavior and that conversation changes dramatically based on feedback (approval) from others.62
244598159McDougal and RossPublished first textbooks on social psychology.63
244598160Zajonc's TheoryThe presence of others increases arousal and emission of dominant responses. At early stage of learning dominant responses are wrong, while later correct responses are dominant.64
244598161The Prisoner's DilemmaTheory asserting that in such a competition it is in both participants best interest to cooperate. When making the decision consider the options 1. I cooperate, you don't 2. We both cooperate 3. Neither of us cooperateds 4. You cooperate, I don't65
244598162CooperationThe voluntary arrangement in which two or more people engage in a mutually beneficial exchange instead of competing66
244598163CompetitionBehavior in which individuals try to attain a goal for themselves while denying that goal to others67
244598164Kurt Lewin's StudyIdentified 3 different styles of leaders: Authoritarian, Democratic and Laissex-fair68
244598165Authoritarian LeaderAutocratic leaders who 1. Provide clear expectations for what needs to be done, when it should be done, and how it should be done. 2. Set a clear division between the leader and the followers. 3. Make decisions independently with little or no input from the rest of the group.69
244598166Democratic LeaderThe most effective leadership style. They 1. Offer guidance to group members while participating in the group and allowing input from other group members. Show less productivity, but higher quality contributions. Group members feel engaged in the process and are more motivated and creative.70
244598167Laissez-fair LeaderLeader who offer little or no guidance and gives complete decision-making freedom to the group or to individual members, often leading to poorly defined roles and a lack of motivation.71
244598168Muzafer Sherif's Conformity StudyShowed that people were influenced by other people's opinions, in their perception of the autokinetic effect.72
244598169Robber's Cave ExperimentThree phase study of prejudice 1. Intragroup cooperation (two groups kept separate to create cooperation and group cohesion) 2. Intergroup competition (groups put into direct competition showed direct hostility) 3. Introduction of subordinate goals (groups forced to work together formed eventual cohesion)73

1322750851inattentional biasyou will not perceive something that you are not attending to, even if you are looking right at it8
1322750854change blindnesswe miss changes that we are not specifically looking for9
1322750857precuingparticipant is presented with a "cue" that indicates where a stimulus is most likely to appear.10
1322750860spreading enhancementeffect of attention that may help us perceive occluded objects; experiment by Robert Egly that showed that when attention is directed to one place on an object, the enhancing effect of this attention spreads throughout the object (ex. bars with targets ABCD); see also experiment by Moore et al. (ex. "animal" lurking behind tree)11
1322750863TruePaying attention to a stimulus makes it stand out more. It makes it seem brighter.12

1322750882Parahippocampal Place AreaPPA is important in encoding and recognizing environmental scenes like place, rooms, or landscapes.`19
1322750884Binding ProblemThe problem confronted by the brain of recombining the elements of a stimulus, given the fact that these elements are initially analyzed separately by different neural systems.20
1322750886feature integration theoryA sequence of steps proposed by Treisman to explain how an object is broken down into features and how these features are recombined to result in a perception of the object.21
1322750887Why Attention is EverythingFocused attention "binds" the features together - Attention is the glue that binds the "what" & "where" streams together In the absence of focused attention, features associated with one object can be incorrectly combined with another. That makes illusions.22
1322750888Illusory ConjunctionsA situation, demonstrated in experiments by Anne Treisman, in which features from different objects are inappropriately combined.23
1322750889Balint's SyndromeA condition caused by brain damage in which a person has difficulty focusing attention on individual objects. (Damage to Parietal Lobe)24
1322750890Synchrony hypothesisthe idea that when an object causes neurons in different parts of the cortex to fire, the timing of the firing of these neurons will be synchronized. This synchrony indicates that all of these neurons are responding to the same object. This idea has been proposed as a solution to the binding problem.25
