Part-list cuing effects in younger and older adults' episodic recall

Area of Science:

• Cognitive Psychology
• Neuroscience of Aging
• Human Memory

Background:

• Retrieval cues can influence memory recall, sometimes impairing it (part-list cuing effect).
• Age-related differences in memory are often linked to changes in cognitive control and context processing.

Purpose of the Study:

• To investigate part-list cuing effects on episodic recall in younger and older adults.
• To examine the role of episodic context access in modulating these effects across age groups.

Main Methods:

• Participants (younger and older adults) performed an episodic recall task.
• Listwise directed forgetting was used to manipulate access to study context at retrieval.
• Part-list cuing (providing some studied items as cues) was manipulated.

Main Results:

• Part-list cuing impaired recall in both age groups when study context was accessible.
• When study context access was impaired, part-list cuing benefited younger adults but not older adults.
• Older adults demonstrated intact inhibition but impaired episodic context reactivation.

Conclusions:

• Older adults' memory performance is differentially affected by retrieval strategies compared to younger adults.
• Reduced episodic context reactivation may underlie age-related deficits in leveraging retrieval cues under specific conditions.
