Explore the impact of social influence on false memory susceptibility in introverts and extroverts. Conducted using Governor's School students to analyze mixed and like-minded groups. Results revealed social contagion effects, with no significant difference between extroverts and introverts. Limitations include uncontrollable variables. Future research includes further applications of the study.

  1. On False Memories: Cognitive Illusions Brian Bruce Runqiu Cai Brian DeAngelis Jason Kimmel Phoebe Kuo Neil Parikh Soha Shah Nathaniel Stornetta Adam Tourgee Julia Xu Sean Yeager Alex Young

  2. Memory • Intrinsic and essential element of human life • Imperfect • Errors of omission • Errors of comission (false memory)

  3. Deese (1959) • Word List • Thimble, haystack, pointy, sharp, thread, pin, eye, sewing, prick • Key word needle unmentioned, but subjects falsely recalled it

  4. Roediger, Meade Bergman (2001) • Confederate social influence • “Social Contagion” • Remembered items in a scene which weren’t there

  5. Big Five • Social/Reserved • Limbic/Calm • Organized/Unstructured • Accommodating/Egotistical • Non-curious/Inquisitive

  6. Ward and Loftus (1985) • Eyewitness accounts • Introverted subjects more susceptible to misinformation

  7. QUESTION: What is the effect of extroversion on the susceptibility to false memory with a factor of social influence from a confederate in a group setting?

  8. HYPOTHESIS: The degree of social contagion will be greater among introverts than among groups composed of extroverts

  9. Methods (Design) • False Memory Susceptibility • Introvert vs. Extrovert • Mixed Group vs. Like-Minded Group

  10. Methods (Participants) • 67 Governor’s School Students • Six Groups • Two Introvert Groups • Two Extrovert Groups • Two Mixed (Controls)

  11. Methods (Procedure) • Distribute personality tests • Make groups • Instruct Confederates • Experiment

  12. Methods (Procedure) • Chronology of Experiment: • Consent form • Magic trick • 2-minute filler test • 8-minute discussion • 5-minute filler test • 5-minute memory implantation test • De-briefing

  13. Discussion Sessions

  14. The Results • Personality Test Average Personality Type: S C O X I Social – Calm – Organized – X - Inquisitive

  15. The Results • Range • Very diverse group, ranged from Low (7) to High (35)

  16. The Results • Reasoning Tests • Overall, Governor’s School students scored significantly higher

  17. Results and Speculations • We got social contagion! • 28% of the implanted items were falsely remembered • 62% had at least one false memory • No difference between extroverts and introverts (contrary to Ward and Loftus)

  18. The mixed groups were much less susceptible to false memory implantation than the like-minded groups.

  19. Limitations and Qualifications • Gov. School students • Slanted SLOAN tests • Random chance/uncontrollable variables

  20. The Future • Further applications • Future research

  23. Rollin’ with Dolan: Cognitive Illusions Brian Bruce Runqiu Cai Brian DeAngelis Jason Kimmel Phoebe Kuo Neil Parikh Soha Shah Nathaniel Stornetta Adam Tourgee Julia Xu Sean Yeager Alex Young

  24. The Results • Linda Reasoning Test Linda is 31 years old, single, outspoken and very bright. At university she studied philosophy. As a student she was deeply concerned with issues of discrimination and social justice and also participated in anti-war demonstrations. ___ Linda is a bank teller ___ Linda is active in the feminist movement ___ Linda is active in the feminist movement and is a bank teller

  25. The Results • Linda Reasoning Test The Right Answer Why?

  26. The Results • Linda Reasoning Test On average, less than 15% of people get this question right when tested in large groups. 42% of the 67 students tested got this question right!

  27. The Results • Chain Test

  28. The Results • Chain Test IT’S NOT IMPOSSIBLE! ~Unlink all of the chains in any line and use them as connectors to link the rest! To unhook the 3 = $.06 and to link them back, $.09 = $.15

  29. The Results • Chain Test ~Governor’s School students did much better! ~9% of students got it correctly in just 5 minutes In a study, people were given 30 minutes to answer it and just ~50% got it right!
