Strategy Selection for Cognitive Skill Acquisition Depends on Task Demands and Working Memory Capacity
Hinze, Scott R.; Bunting, Michael F; Pellegrino, James W.
Learning and Individual Differences, v19 n4 p590-595 Dec 2009
The involvement of working memory capacity (WMC) in ruled-based cognitive skill acquisition is well-established, but the duration of its involvement and its role in learning strategy selection are less certain. Participants (N=610) learned four logic rules, their corresponding symbols, or logic gates, and the appropriate input-output combinations in three-gate circuit patterns. Participants practiced 120 repetitions of each rule (480 total gates) over the course of 10 training blocks. Memory load varied between subjects. The confluence of task demands and individual differences in WMC (N=518) dramatically affected speed-accuracy tradeoffs and strategic use of a computerized help function. Cluster analysis revealed five distinct groups of participants based on the combination of response accuracy, latency, and help use. Some groups with moderate to high mean WMC acquired the task with predictable performance patterns. Other groups, prevalently under a memory load and with low mean WMC, failed to learn or overused help. (Contains 4 tables and 4 figures.)
