Exploring the enactment effect from an information processing view: what can we learn from serial position analyses?

Area of Science:

• Cognitive Psychology
• Neuroscience of Aging

Background:

• Memory performance declines with age.
• Enactive encoding (learning by doing) may enhance memory retention.
• Repeated learning is a known strategy for memory improvement.

Purpose of the Study:

• To analyze age effects and enactment in free recall.
• To investigate serial position effects in memory recall.
• To compare enactive versus verbal encoding in different age groups.

Main Methods:

• Experimental study with younger and older participants.
• Multi-trial free recall paradigm.
• Comparison of enactive encoding and verbal encoding.
• Analysis of serial position effects (e.g., primacy, recency).

Main Results:

• Memory performance improved with repeated learning, irrespective of age.
• Enactive encoding yielded better memory recall than verbal encoding for both age groups.
• Younger adults demonstrated superior memory recall compared to older adults.
• Enactive encoding particularly benefited recall of later list items.
• Task repetition enhanced recall of middle items (SPT/VT) and last items (VT).

Conclusions:

• Enactive encoding and repeated learning are effective memory enhancement strategies across the adult lifespan.
• Significant age-related differences in memory recall persist, with younger adults showing better performance.
• Understanding serial position effects in different encoding conditions provides insights into memory processes.
