1 Forming Impressions of Others: A Classroom Demonstration

2 Introduction This demonstration was created by Jackson (2000) and is based on an actual study by Hamilton and Gifford (1979).

3 Instructions You will see a series of statements, each describing a person performing some type of behavior. Each person belongs to either Group A or Group B. After all statements have been presented, you will respond with your impressions.

42 Craig helped a friend move.

43 Done!

44 Group Ratings Construct the table below on a scrap piece of paper.

45 Group Ratings Attribute:Group AGroup B Popular Lazy Unhappy Intelligent Honest Irresponsible Helpful Unpopular

46 Group Ratings Your next task is to rate each of the groups. Use the scale below: 1: Strongly Disagree 7: Strongly Agree You should use intermediate values as well as these two extremes.

47 Debriefing Group A (n = 26 members) 18 positive statements 8 negative statements 9:4 ratio of positive to negative statements Group B (n = 13 members) 9 positive statements 4 negative statements 9:4 ratio of positive to negative statements

48 Debriefing The ratio of positive and negative events was exactly the same for Group A and Group B! Did we rate the Groups the way we should have? Are our ratings of the Groups exactly equal?

49 Illusory Correlation This demonstration illustrates an Illusory Correlation – the perception of a relationship where none exists, or perception of a stronger relationship than actually exists. Another way to think of it – a false impression that two variables correlate.

50 Illusory Correlation The joint occurrence of two distinctive events (minority member – Group B & distinctive event - negative behavior) probably attracted more attention and caused faulty impressions.

51 Illusory Correlation Examples: It always rains on the week-end It always rains after you wash the car The phone always rings when you are in the shower Librarians are quiet Doctors are wealthy

52 Illusory Correlation The Illusory correlation may be one reason individuals become prejudiced. Research has shown that White Americans overestimate the arrest rate of African Americans (Hamilton & Sherman, 1996). African Americans = minority Arrest Rate = distinctive event
