Elaborative retrieval: Do semantic mediators improve memory?

Area of Science:

• Cognitive Psychology
• Educational Psychology
• Learning Sciences

Background:

• The elaborative retrieval account suggests retrieval practice boosts memory by creating semantic mediators.
• This account assumes mediators are generated more during retrieval than restudy.
• It also assumes mediator generation aids future recall.

Purpose of the Study:

• To empirically test the core assumptions of the elaborative retrieval account.
• To investigate whether semantic mediators are preferentially generated during retrieval versus restudy.
• To examine the relationship between mediator generation and subsequent memory recall.

Main Methods:

• Conducted seven experiments measuring mediator generation during retrieval and restudy phases.
• Assessed the impact of mediator generation on subsequent free and cued recall of target information.
• Utilized controlled experimental designs to isolate the effects of retrieval and restudy.

Main Results:

• Mediator generation was not more likely during retrieval; it may be more likely during restudy.
• Mediator activation showed no significant relationship with subsequent free recall.
• Mediator activation was negatively correlated with subsequent cued recall.

Conclusions:

• The findings challenge the assumption that retrieval uniquely promotes mediator generation.
• The results question the proposed mechanism linking mediator generation to enhanced retention.
• The study suggests a need to revise or reconsider the elaborative retrieval account of learning.
