learning; nurtureBiological: physiology; genetics; natureCognitive: mental processesPsychoanalytical: unconscious; childhoodHumanistic: freewill; basic goodnessMulticultural: sociocultural; role of structureGestalt: emphasizes the organization process in behavior; focuses on problem of perceptionPersonality:Psychoanalytic: people are driven by instincts, largely sexualBehaviorist: behavior is personality; determined by history of reinforcementHumanistic: people are inherently good, society ruins them, people strive to satisfy a hierarchy of motives toward self-actualizationCognitive: people are rational and want to predict and control their world, personal constructs help in this processBiological: biological factors such as body type or geneticsAbnormal:Psychoanalytic: emerge from initial psychological conflicts that are unconscious, often arising from childhood traumaBiomedical: traceable to physical abnormalities, biochemistry, structural defectsCognitive: results from unusual ways of thinking, inappropriate belief systemBehavioral: results from faulty contingencies of reinforcement contexts contribute to the development of psychological disordersCultural: variables such as social class, gender, and rural-urban contexts contribute to the development of psychological disordersHumanistic/Existential Model: results from failure to fulfill ones potentialTreatment:Biomedicala) ECTb) Psychosurgery; ablationc) Chemotherapyd) Intensive light therapy (S.A.D.)Psychoanalytic Therapy – alleviate unconscious conflictsFree associationDream analysisTransferenceSymptom substitutionBehavior Therapy – application of learning principlessystematic desensitizationin vivo desensitizationcounter conditioningflooding (real event)implosive therapy (imagine the event)aversion therapyCognitive-Behavior Therapy – thoughts and behaviormodeling and role playrational emotive therapy: forces a more realistic look in the evaluation circumstancesstress inoculation therapy: retractors inappropriate thinkingcognitive therapy: used for depression; requires the restructuring of persons invalid perceptions of self, future, and the world or experienceHumanistic – focuses on getting the person to accept the responsibility for their improvementRoger’ client centered therapy (unconditioned positive regard)Frankl’s existential analysis treatment: help client gain sense of purpose and meaningGestalt therapy: client comes into contact with the whole selfBiomedical Treatment – includes medical procedures and medication that can help alleviate symptoms of psychological disorderspsycho-surgery (ablation)surgical destruction of involved brain tissuesobsessive-compulsive disorderelectroconvulsive therapy (ECT)major depressionpsychopharmacological treatmentneuroleptics (antipsychotics) i.e. thorozine, haldol, clozerilantidepressants i.e. tricyclic compounds, selective serotonin reuptake inhibitors, prozaclithium carbonate (bipolar disorder)anxiolytics (anti anxiety) i.e. valium, benzodiazeopinesThe Experiment:1. Two variables are studied for cause and effectIndependent variable – manipulatedDependent variable – the response; measuredConfounding variable – other variables that may influence resultsExperiment group – exposed to manipulation of independent variableControl group – an unaffected comparison groupSubject bias – a subject’s behavior changes due to believed expectations of experiment (Demand characteristics)Researcher bias – expectations influence what is recordedDouble-blind technique – control for bias by keeping placement of subject secretPlacebo – inactive substance unknowingly given in place of drugNull hypothesis – negatively expressed hypothesis; X will not change YTheoriesPiaget’s Cognitive-Development Theory:Sensory Motor: schema assimilation and accommodation; circular reaction; object permanencePreoperational: egocentrism; animism; artificialismConcrete: operational-reversibility; conservative problemsFormal: operational-personal fableKohlberg’s Moral Judgment:Preconventional: good and bad; right and wrongConventional: social rules; follow the lawPostconventional: universal principlesErickson’s Psychosocial Development:INFANCYtrust vs. mistrustAutonomy vs. shame and doubtCHILDHOODinitiative vs. guiltIndustry vs. territoryASOLESCENCEidentity vs. role confusionADULTHOODintimacy vs. isolationGenerality vs. stagnationEgo integrity vs. despairKubler-Ross’ Stages of DeathDenialAngerBargainingDepressionAcceptanceTheories:Weber’s law: just noticeable differenceYoung-Helmholtz Color Theory: (trichromatic theory) color determined by the relative activity in red, blue, or green sensitive conesOpponent-Process Color Theory: color information is organized into 3 antagonistic pairsPlace Theory: relates perceived pitch to regionFrequency Theory: related pitch to the frequency of sound waves and frequency of neuron firingFacial Feedback Hypothesis: sensations from the face provide cues to the brain that help us determine what emotion we are feeling (Ekman)Statistical Significance: .05 chance accounts for results less than 5% of the timeTemplate-Matching Theory: stored copiesPrototype-Matching Theory: recognition involves comparisonFeature-Analysis Theory: patterns are represented and recognized by distinctive featuresRestorative Theory: we sleep in order to replenishAdaptive Non-responding Theory: sleep and inactivity have survival valueActivation-Synthesis hypothesis: dreams are products of spontaneous neural activityThorndike’s Law of Effect: reward and punishment encourages and discourages respondingPremack Principle: states that any high-probability behavior can be used as a reward for any low-probability behaviorContinuity vs. Discontinuity: theories of development, nature vs. nurtureSerial Position Phenomenon: sequence influences recallPrimacy Effect: enhanced memory for items presented earlierRecency Effect: enhanced memory for items presented lastAtkinson-Shiffrins 3 Stage Processing model of memory: sensory-STM-LTMLinguistic Relativity Hypothesis: person’s language determines and limits a persons experiencesHull’s Drive-Reduction Model: motivation arises out of needCognitive Consistency Theory: cognitive inconsistencies create tension and thus motivate the organismFestinger’s Cognitive Dissonance Theory: reconcile cognitive discrepanciesArousal Theories: we all have optimal levels of stimulation that we try to maintainYerkes-Dodson Law: arousal will increase performances up to a point, then further increases will impair performance; inverted U functionIncentive Theory: behavior is pulled rather then pushedJames-Lange Theory: emotion is caused by bodily changesCannon-Bard’s Thalamic Theory: emotional expression caused by simultaneous changing bodily events, thoughts, and feelingsSchachter’s Cognitive-Physiological Theory: bodily changes, current stimuli, events, and memories combine to determine behavior- Schachter’s 3-factorsAttribution Theory: explains how people make inferences about the causes of behavior; personal or situational; self-serving biasDeindividuation: loss of self-restraint that occurs out of anonymityContact Theory: proposes that equal-status contact between antagonistic groups should lower tension and bring harmonySelye’s General Adaptation Syndrome- (GAS) emergency reaction to stressful situations; alarm reaction, resistance, and exhaustion (ARE bad)Lazarus’s Cognitive-Psychological Model: emphasizes the process of appraisal (primary and secondary) as the primary determinant of stressTwin Studies: allows a researcher to test influence of heredity vs. environmentPersonal Construct Theory: unique system of realityDeinstitutionalization: occurred because of changes in political policy and development of new drug therapiesAinsworth’s Strange Situation: looked at attachment in young children to their parentsSocial Psychology Studies:Zimbardo’s Standford Prison Study: effect of rolesHawthorne Effect: people change their behavior when they think that they’re being observedLatane & Darley’s Bystander Effect: diffusion of responsibility (Kitty Genovese )Asche’s Conformity Study: lines of different length; 33%Milgram’s Obedience Study: shocking the confederate (65% delivered full range)Sherif: Autokinetic Phenomenon; conformity studiesJane Elliot’s Blue Eyed/Brown Eyed Experiment: development of prejudice, scapegoatingSocial PressureConformity: occurs when individuals adopt the attitudes or behavior of others because of real or imagined pressureSocial Norms: shared standards of behaviorReciprocity Norm: people tend to treat others as they have been treatedCompliance: to get along with a request made of you from a person who does not have authority over you, techniques includeFoot in the door technique: if a small request is made first, a larger request will be easier to fill laterDoor in the face technique: making a larger request first then making a smaller one which will seem more reasonable (high balling)Low balling: getting agreement first, then adding specifics laterNorm of Reciprocity-give something small expect something bigger in returnObedience: compliance with someone who has authoritySocial Traps: behave in an unproductive way because of fear others willAltruism: self concern for othersBystander intervention: will individuals intervene in a harmful situation to anotherBystander effect: people are less likely to help when several people witness an emergency due to diffusion of responsibility, thinking that someone else can be responsibleSocial facilitation: tendency to do better on well-learned tasks when another person is presentSocial loafing: reduction in effort by individuals when they work in groups compared to by themselvesRisky shift: groups often arrive at riskier decisions than do individualsDeindividuation: loss of identity as a result of being part of a groupGroupthink: members of a cohesive group emphasize agreement at the expense of critical thinkingSuperordinate goals: task completed only with complete cooperation of both parties ................
