  1. PROJECT PResentation Mentor: Prof. Amitabh Mukherjee Effect of trust on social conformity in Recognition Memory Pranjal Saxena Y9424 SE 367: Introduction to Cognitive Science

  2. OVERVIEW • Social Conformity: • Act of matching attitudes, beliefs, and behaviours. • Why Recognition memory? • Relevant in Eyewitness testimony. • Peer influence altering memories of incidents. • Friends and Strangers: • Conformity is larger among friends than strangers. • Exception : McKelvey, Wendy; Kerr, Nancy H. (1988) SE 367: Introduction to Cognitive Science

  3. OBJECTIVES SE 367: Introduction to Cognitive Science

  4. EXPERIMENT • Database of 130 images: onemillionpeople.com • A trial: 4 confederates ,1 participant. • Participant convinced to be a part of a “memory test”. • Conf. have doctored responses written on their sheets. Image cited from "Graded effects of Social Conformity on Recognition memory" • Encoding :50 images shown with a gap of 2 seconds. • Retrieval: • Another set of images. Part. Identify new and old images. • Part. Respond loudly after the Conf. • 10 trials each for strangers and friends cases. • Hits(no of correct recognitions of old) • false alarms(no of false recognition of new items) Plotted Separately SE 367: Introduction to Cognitive Science

  5. RESULTS 1> Experiment1 : Setting a base case: Establishing that memory is better than chance and evaluating memory efficiency in absence of conformity. SE 367: Introduction to Cognitive Science

  6. 2> Experiment2 : Effects of conformity STRANGERS FRIENDS No of correct confederates COMPARISON: DISTRIBUTION IN OLD AND NEW SE 367: Introduction to Cognitive Science

  7. DISCUSSION • Conformity effects well established: • Correct responses of the participant decreased as No. of incorrect Conf. Increase from 0 to 4. • Coherence with study of Axmacher[1]. • Conformity stronger with friends than strangers: • This case being Informational Influence(conforming to give accurate information) • McKelvey, Wendy; Kerr, Nancy H. (1988): opposite results • Case being Normative Influence • Conforming to be acceptable and liked by a group. • Conformity effects larger on Hits than False Alarms: • More likely to forget old memories rather than form new memories. • Replication of Axmacher’s results in short version. • Diverts from previous studies.
