Item-specific processing reduces false recognition in older and younger adults: Separating encoding and retrieval...

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human Development

Background:

• Memory accuracy declines with age, often accompanied by increased false recognition.
• Cognitive strategies during encoding can influence memory performance and susceptibility to errors.

Purpose of the Study:

• To investigate the impact of item-specific and relational processing on memory accuracy in younger and older adults.
• To compare the effectiveness of these processing strategies against a read-only control condition.
• To elucidate the underlying encoding and monitoring mechanisms contributing to memory performance differences.

Main Methods:

• Utilized a categorized-list paradigm with younger and older adults.
• Assessed correct and false recognition rates under item-specific, relational, and read-only processing conditions.
• Applied signal-detection and diffusion-modeling analyses to recognition responses and latencies.

Main Results:

• Both item-specific and relational processing improved correct recognition compared to the read-only control in both age groups.
• Item-specific processing significantly reduced false recognition across both age groups.
• Signal-detection and diffusion models indicated that item-specific processing benefits stemmed from enhanced encoding and monitoring processes, similarly in younger and older adults.

Conclusions:

• Item-specific processing effectively enhances memory accuracy by improving both encoding and monitoring functions.
• Older adults benefit from item-specific processing to a similar extent as younger adults, suggesting preserved cognitive plasticity.
• These findings highlight the potential of targeted cognitive strategies to mitigate age-related memory changes.
