  2. Definition • A predisposition to respond to a particular object in a generally favorable or unfavorable way • A person’s attitudes influence the way in which he or she perceives and responds to the world. (Allport, 1935; Thomas and Znaniecki, 1918)

  7. 為什麼態度研究在社會心理學佔重要地位 • 態度與行為有關 • 經濟因素: 商業, 消費 • 政治因素: 宣傳, 民主競選 • 軍事因素: 宣傳, 提升士氣, 心戰

  8. Attitude formation • Social learning and socialization • Classical conditioning • Instrumental conditioning • Observational learning • More complicated learning and socialization processes (educational effects on attitudes)

  9. Functions of attitudes • Heuristic (instrumental) • Schematic (knowledge) • Define the self and maintain self-worth • Protective, direct anger toward minority

  10. Functions of Attitudes • Value-Expressive function • enable us to express who we are and what we believe in • Ego-defensive function • enable us to project internally-held conflicts onto others (e.g., homophobia) • Knowledge function • enable us to know the world • Utilitarian Function • Enable us to gain rewards and avoid punishment

  11. Cognitive consistency • Balance theory • Cognitive dissonance theory • Festinger

  12. Theory of cognitive dissonance • Postdecision dissonance • Counterattitudinal behavior • Dissonance effect • Incentive effect • When Prophecy Fails: a social and psychological study of a modern group that predicted the destruction of the world 1964

  13. Ready to turn some pegs?? • Students spent hour turning pegs in holes (really boring) • Paid either $1 or $20 • Who enjoyed the task more (when asked later)? • Why $1 people  $20 was justification enough, $1 wasn’t – I must have really liked turning pegs! (Festinger & Carlsmith, 1959)

  14. Post-decisional dissonance 被選的 沒被選的 選擇

  16. 社會影響與說服Social Influence and Persuasion

  17. 社會影響的定義和類別 • 一個人的行為使得另外一個人的想法或行動因而有所改變是為社會影響。 • 社會影響的類別 • 態度變遷（Attitude Change） • 順從（Compliance） • 服從（Obedience）

  18. 態度變遷（即說服 Persuasion） • 影響來源者（Source)用訊息（message, information）改變了目標對象（Target）對議題、對人、或對情況的態度和信念（beliefs） • Who (Source) says what (Message) to whom (Target) to gain what effect? • 許多其他作者態度與態度變遷和社會影響的主題是分開的。

  19. 順從（Compliance） • 影響來源者（Source）經由獎勵（reward）或懲罰（punishment）來鼓勵（promise）或威脅（threat）目標對象（Target）改變行為 Source顯然控制是否給予獎懲的力量

  20. 服從（Obedience） • 影響來源者是以命令（order）來要求目標對象接受權威的正當性（authority’s legitimacy）。 • Order is ligitimate.

  21. 來源 訊息 目標 效果 專業 可信度 吸引力 差距 訴諸恐懼 單向或雙向 改變態度 拒絕訊息 反駁 暫停 貶損來源 智力 涉入 預受警

  22. 影響來源 • 專業性（expertise） 支持通過消費者保護法 同樣的訊息內容，不同的人來說 1. 哈佛畢業的律師，在消費者議題上很熟悉 2. 一位關心消費者的民眾 原先反對者表示接受那位律師的說法比較多 --目標對象對議題的涉入與知識也有影響

  23. 可信賴度（trustworthiness） 說服者若違反對自己的利益就最有說服力 說服者身份的影響，若說服者被認為和目標對象有相類似的目標，就愈有說服力

  24. 吸引力 • 個人外表的吸引力影響說服力 • 說服者若美貌有吸引力會讓人更注意到說服的訊息，注意力會促成說服的效果。 • 吸引力和論辯強弱 • 論辯強（strong argument），吸引力影響更大

  25. 多種來源的效果 • 社會影響論（social impact theory） 影響力（the impact of influence attempt）是強度（strength, social status or power）、可及性（immediacy, physical or psychological distance）、和來源數（number of influencing sources）的函數。 論辯來自多源，說服力比較大，強論辯尤其如此。 獨立多源 有上限

  26. 訊息（message) • 訊息差距

  27. 引發恐懼（fear arousal） • 訴諸理性和訴諸情緒 • 訴諸恐懼有說服力（中度） • 太強太極端，使人受到嚴重威脅，就無效 • 強調若改變行為，就會有嚴重後果 • 顯示負面後果很可能發生的證據 • 要提出有效避免嚴重後果的明確做法

  28. Opinion change (Hovland et al., 1949) The message

  29. 目標對象（涉入，involvement）

  30. 認知的需求（Need for cognition） • 中樞途徑 • 分心（distraction） • 邊緣指標，途徑

  31. 順從 • 威脅與獎勵，信譽 • SEV（subjective expected value）

  34. 社會權力（social power） 1.Promise of reward 2.Coercion through threat 3.Referent power 4.Legitimate power 5.Information 6.Expertise

  35. 服從（Obedience） • Obedience • compliance of person is due to perceived authority of asker • request is perceived as a command • Milgram interested in unquestioning obedience to orders (blind obedience)

  36. Stanley Milgram’s Studies • Teacher to another room with experimenter • Shock generator panel – 15 to 450 volts, labels “slight shock” to “XXX” • Asked to give higher shocks for every mistake learner makes

  37. 120 150 300 330 “Ugh! Hey this really hurts.” “Ugh! Experimenter! That’s all. get me out of here. I told you I had heart trouble. My heart’s starting to bother me now.” (agonized scream) “I absolutely refuse to answer any more. get me out of here You can’t hold me here. Get me out.” “(intense & prolonged agonized scream) “Let me out of here. Let me out of here. My heart’s bothering me. Let me out, I tell you…” Stanley Milgram’s Studies • Learner protests more and more as shock increases • Experimenter continues to request obedience even if teacher balks

  38. Obedience • How many people would go to the highest shock level? • 65% of the subjects went to the end, even those that protested

  39. Percentage of subjects who obeyed experimenter Slight (15-60) Moderate (75-120) Strong (135-180) Intense (255-300) Very strong (195-240) Extreme intensity (315-360) Danger: severe (375-420) XXX (435-450) Shock levels in works Obedience

  40. Percentage of subjects administering the maximum shock (450 volts) Follow-Up Studies to Milgram • Original study • Different building • Teacher withlearner • Put hand on shock • Orders by phone • Ordinary man orders • 2 teachers rebel • Teacher chooses shock level

  41. 抗拒影響與說服 • 免疫（inoculation）McGuire • 預先警告（Forewarning） • 抗拒（reactance）獨立和自由受到威脅

  42. Inoculation Theory McGuire and Papageorgis (1961) proposed that people who are educated about opposing arguments are more resistant to those arguments later on.

  43. “Everybody should get a chest x-ray each year in order to detect tuberculosis” • “Everybody should brush their teeth after every meal if at all possible.” • Participants received an essay that included counterarguments against the health beliefs. • Attitudes were measured in four experimental groups.

  44. Control group. No counterarguments. • Inoculation group. Informed about counterarguments and information to undermine it. • Additional support. Received further information supporting the attitude. • No defense. No additional information to defend against counterarguments.

  45. Inoculation Effect on Resistance to Counterarguments

  46. The Elaboration-Likelihood Model of Persuasion (Petty & Cacioppo, 1986) Central Route to Persuasion Yes Attitude Change Persuasive Communication Ability & Motivation to pay attention? Peripheral Route To persuasion No
