Lecture Outline: Personality I. Introduction What is Personality? -- Distinctive set of consistent traits Example: Big Five Model (see Figure 11.1) O penness to Experience C onscientiousness E xtraversion A greeableness N euroticism How do we measure personality? What are the causes of personality? II. Personality Assessment: How do we measure personality? A. Self-report inventories 1. Strengths: Quick, inexpensive, easy to administer, objective scoring 2. Weaknesses: Response biases - making us answer in a more socially desirable way What about those personality quizzes in magazines and on the internet? -- No empirical data on validity -- Personality tests in popular magazines often rely on the Barnum effect -- “Always have a little something for everybody.” -- PT Barnum -- Every result tends to be vague (so it fits anyone) and positive (so you’ll believe it). B. Projective tests 1. Ambiguous stimuli, such as a. Pictures (Thematic Apperception Test) b. Inkblots (Rorschach Test) c. Sentence completions 2. Assumption: Responses to ambiguous stimuli will reveal personality traits. 3. Weaknesses: Difficult to score, low validity, not reliable, response biases
