Translating (lack of) memories into reports: Conversion processes in responding to unanswerable questions

Area of Science:

• Cognitive Psychology
• Memory Research
• Metacognition

Background:

• Individuals encounter both witnessed-answerable and unwitnessed-unanswerable questions about past events.
• Willingness to answer known details increases with available information and context.
• The impact of context on reporting incorrect information for unknown details is less understood.

Purpose of the Study:

• To investigate if contextual information influences the willingness to provide incorrect answers for unanswerable questions.
• To determine if reinstated contexts increase commission errors for non-encoded details.

Main Methods:

• Conducted three experiments examining participants' responses to recognition questions.
• Manipulated the reinstatement of contextual information prior to critical detail questions.
• Assessed participants' willingness to respond "don't know" versus making a specific (incorrect) guess.

Main Results:

• Reinstated contexts significantly reduced participants' willingness to respond "don't know" to unanswerable questions.
• Participants made more commission errors (reporting incorrect details) when context was reinstated.
• Increased contextual information, beneficial for answerable questions, led to greater inaccuracy for unanswerable ones.

Conclusions:

• Contextual information can impair memory accuracy by increasing false reporting for unanswerable questions.
• Conversion processes, including memory monitoring and output control, are crucial in shaping memory report accuracy.
• Findings highlight the dual role of context in memory: aiding recall for known information and potentially distorting reports for unknown information.
