Selective directed forgetting: Eliminating output order and demand characteristics explanations

Area of Science:

• Cognitive Psychology
• Memory Research

Background:

• Selective directed forgetting (SDF) impairs recall of to-be-forgotten items.
• Previous research suggests executive control underlies SDF.
• Alternative explanations, such as output interference and demand characteristics, remain unexplored.

Purpose of the Study:

• To investigate whether output interference or demand characteristics explain the SDF effect.
• To differentiate between cognitive control and procedural explanations for SDF.

Main Methods:

• Two experiments were conducted to test alternative explanations for SDF.
• Experiment 1 examined the influence of output interference on to-be-forgotten items.
• Experiment 2 assessed the role of demand characteristics by offering monetary rewards for recall.

Main Results:

• To-be-forgotten items were less accessible and unaffected by output interference from to-be-remembered items.
• The SDF effect persisted even when participants were incentivized to maximize recall.
• Findings did not support explanations based on output interference or demand characteristics.

Conclusions:

• The results challenge procedural explanations for the SDF effect.
• Alternative cognitive mechanisms, potentially involving executive control, are likely responsible for SDF.
• Further research is needed to elucidate the precise cognitive processes underlying directed forgetting.
