The plasticity of early memory reports: social pressure, hypnotizability, compliance, and interrogative suggestibility.

Early autobiographical memory reports by adults were very sensitive to social influence in a leading interview. The mean age of initial earliest memory report was 3.7 years. When participants were instructed to close their eyes, visualize, and focus on their 2nd birthday, 59% reported a birthday memory. After repeated probes for earlier memories, 78% of subjects reported memories at or prior to 24 months of age, and 33% reported memories within the first 12 months of age. The mean age of the final earliest memory reported was 1.6 years. Participants rated their memory reports as accurate and did not recant them when given an opportunity. The age of earliest memory reports in the suggestive interview correlated negatively with measures of compliance, hypnotizability, and interrogative suggestibility.
