The effect of enactment on memory for order

Area of Science:

• Cognitive Psychology
• Memory Research
• Human Memory

Background:

• Enactment effect in memory research.
• Distinction between item and order information in memory.
• Role of encoding strategies in memory recall.

Purpose of the Study:

• Investigate the impact of enactment on serial order memory.
• Examine how knowledge of a future memory test influences enactment effects.
• Clarify the contribution of enactment to item versus order memory.

Main Methods:

• Two experiments utilizing a reconstruction task to differentiate item and order memory.
• Manipulation of enactment type (verbal vs. motor) and test awareness (informed vs. uninformed).
• Within-subjects and between-groups designs were employed.

Main Results:

• When unaware of the test, verbal and motor enactment yielded similar memory performance for serial order.
• Subjects informed about the serial order test showed superior performance with verbal encoding compared to motor enactment.
• The reversed enactment effect for informed subjects was replicated in a within-subjects design.

Conclusions:

• Enactment primarily enhances memory for item information, not serial order.
• Encoding during enactment may offer less subject control compared to verbal encoding.
• Findings support theories positing enactment's specific role in item memory enhancement.
