Explanation can cause Forgetting: Memory Dynamics in the Generation of New Arguments

Area of Science:

• Cognitive Psychology
• Memory Research

Background:

• Retrieval-induced forgetting (RIF) occurs when recalling information impairs memory for related, non-retrieved information.
• The current study explores if similar forgetting dynamics apply to argument generation during explanation.

Purpose of the Study:

• To investigate argument-induced forgetting in the context of explanation.
• To determine if generating new arguments affects recall of previously studied arguments.

Main Methods:

• Participants studied arguments on various issues.
• They then generated new arguments for a subset of these issues.
• Memory recall for studied arguments was tested later.

Main Results:

• Attempting to generate new arguments led to decreased recall of studied arguments (argument-induced forgetting).
• This effect persisted whether generated arguments agreed or disagreed with studied ones.
• The forgetting effect was significantly reduced when generated arguments were highly related to studied arguments.

Conclusions:

• Argument generation can induce forgetting of previously learned information, analogous to retrieval-induced forgetting.
• The degree of semantic relatedness between studied and generated arguments moderates this forgetting effect.
• High relatedness between arguments may inhibit argument-induced forgetting by promoting information integration.
