Distributed retrieval practice promotes superior recall of anatomy information

Area of Science:

• Cognitive Science
• Anatomy Education

Background:

• Effortful retrieval and distributed practice are known to improve long-term memory recall.
• However, their combined effect on learning anatomy has not been previously investigated.

Purpose of the Study:

• To investigate the additive effects of retrieval practice and distributed learning on anatomy information retention.
• To compare different learning strategies combining studying, retrieval, massed, and distributed practice.

Main Methods:

• Participants learned skeletal muscle anatomy using five different strategies over varying time periods.
• Strategies included studying only (SSSS) and a combination of studying and retrieval (SRSR) under massed (2-day) and distributed (7-day) conditions.
• Learning sessions were standardized to 12 phases over 24 minutes, with recall assessed one week later.

Main Results:

• Distributed practice strategies (SRSR7,2,0 and SRSRSR2,0) significantly outperformed massed strategies (SRx60).
• Retrieval-based strategies (SRSR7,2,0 and SRSRSR2,0) showed superior recall compared to studying-only strategies (SSSS7,2,0 and SSSSSSS2,0).
• The combination of distributed practice and retrieval (SRSR7,2,0) resulted in the highest anatomy information recall.

Conclusions:

• Distributed learning enhances anatomy recall more than massed learning.
• Retrieval practice is more effective than passive studying for anatomy retention.
• The integration of distributed practice and retrieval methods offers the most effective strategy for long-term anatomy learning.
