Implication

Meta-analysis reveals superior task performance following spaced practice compared to massed practice, indicating that task characteristics and timing moderate practice benefits.

Key Points

To determine the overall effect of massed versus spaced practice on task performance and identify variables that moderate this relationship.
Synthesized data from 63 studies yielding 112 effect sizes comparing massed and spaced practice conditions.
Analyzed potential moderating factors, including task type, intertrial time interval, interaction between task and timing, and study methodological rigor.
Spaced practice produced significantly greater performance than massed practice, with an overall mean weighted effect size of 0.46.
The effect of practice distribution was significantly moderated by the nature of the task, the intertrial time interval, and the interaction between both factors.
Studies evaluated as having low methodological rigor reported significantly higher effect sizes than those characterized by higher rigor.
