Effect of Task Similarity on Transfer Performance

Abstract

Transfer of training was studied using a discrete tracking task which involved aiming at targets on a moving paper strip. The effects of target speed, target size, and task demand (number of targets aimed at in each trial) were examined separately in three experiments. In Experiment 1, a difference in stimulus input (i.e., target speed) produced large differences in task strategy (i.e., speed vs. accuracy bias). No significant transfer was found. A difference in target size (Experiment 2) involves a change in stimulus input, but this did not result in large strategy differences. Significant transfer was found when transferring from large to small targets. In Experiment 3, a variation in task demand produced different task strategies without a change in stimulus input. Significant transfer was found in all groups. The results were discussed in terms of similarity in perceptual elements and task strategy between transfer and training tasks. Greater similarity overall led to greater transfer.
