Changing the criterion for memory conformity in free recall and recognition

Area of Science:

• Cognitive Psychology
• Social Psychology

Background:

• Memory conformity describes how social influence affects recall.
• Previous research established this effect in free recall and recognition tasks.

Purpose of the Study:

• To investigate if response criteria influence accurate, inaccurate, and suggested memory responses similarly.
• To explore the complex interplay between response criteria, memory conformity, and secrecy.

Main Methods:

• Two studies were conducted: one with scene recall and another with face recognition.
• Participants' responses were manipulated using varying levels of recall strictness (lenient vs. strict) and secrecy.
• Confederates were used to introduce suggested information.

Main Results:

• Strict recall instructions reduced suggested inaccurate information but also decreased accurate recall.
• Response criterion shifts affected accurate, inaccurate, and suggested responses consistently across both studies.
• Secrecy effects were complex and contingent on the response criterion level.

Conclusions:

• Response criteria significantly modulate memory conformity, impacting all types of recalled information.
• Findings have implications for optimizing eyewitness interviewing and lineup procedures.
• Understanding these dynamics is crucial for accurate memory retrieval in social contexts.
