Summary
This review paper examines the efficacy of part-task training for acquiring tracking and manual control skills, specifically within the context of aviation and flight simulation. The authors define part-task training as practicing specific components of a whole task prior to performing the entire task, with the primary goals of reducing training costs and improving learning efficiency. The review focuses on three specific part-task procedures: segmentation (partitioning tasks by time or space), fractionation (isolating simultaneous subtasks), and simplification (reducing task difficulty). The authors emphasize that valid conclusions require a Transfer of Training (TOT) experimental design, which compares experimental groups trained on parts against control groups trained on the whole task, ensuring equivalent practice time and assessing performance on a criterion task. The analysis of segmentation reveals it to be the most promising technique, particularly when using backward chaining. In this method, learners practice the final, most difficult segment of a task first, then progressively add earlier segments. Studies cited, such as Bailey et al. (1980) and Wightman (1983), demonstrate that backward chaining significantly reduces errors and accelerates learning compared to whole-task practice, especially for low-aptitude subjects. The authors hypothesize that this effectiveness stems from minimizing interference with knowledge of results; by mastering the terminal segment first, learners receive immediate feedback, whereas earlier segments in whole-task training are separated from potent feedback by subsequent actions. Fractionation, which involves isolating simultaneous components like pitch and roll, yields mixed results. The review finds that fractionation is generally less effective than whole-task training, particularly when subtasks have high interaction or when individual components are too easy to warrant isolated practice. However, positive transfer was observed in complex tasks with low subtask interaction and high overall difficulty, such as a video game study by Mane (1984), where part-task training resulted in transfer gains exceeding 100%. The authors note that simplistic partitioning methods often fail, suggesting that systematic task decomposition is crucial for success. Simplification procedures, such as reducing control-display lag or pretraining perceptual skills, show limited utility. While some adaptive training methods show promise, passive viewing of tasks or isolated perceptual training often fails to transfer effectively to manual control performance. The authors conclude that part-task training is not universally superior; its effectiveness depends heavily on task difficulty, subtask interaction, and learner aptitude. Segmentation via backward chaining is identified as the most robust method for difficult, sequential tasks, while fractionation requires careful consideration of subtask independence. The review calls for further research into the stages of skill development to better align part-task strategies with natural learning hierarchies.
Key finding
Part-task training, particularly segmentation via backward chaining, can improve learning efficiency and transfer to whole-task performance for difficult tasks and low-aptitude learners, whereas fractionation is generally less effective unless subtask interaction is low.
