Abstract

The objective of the study was to assess the effects of interruption task similarity and complexity on performance of a simulated industrial assembly operation. Eighteen participants performed a simulated industrial assembly operation, including one trial with no interruption and eight others presenting an interruption task. Interruption conditions comprised a full crossing of task similarity to the primary assembly operation (similar, dissimilar) and complexity (simple, complex) with replication for each participant. Order of condition presentation was randomized. Findings revealed greater time to return to primary visual-manual assembly performance after a similar task interruption. Results also indicated complex interruptions may promote cognitive arousal that increases productivity following assembly interruptions. The majority of results are explained in terms of the Activation-Based Memory for Goals model. Findings provide some guidance for interruption management protocol design for workers engaged in procedural visual-manual assembly operations.

5. Conclusions

The primary objective of this study was to assess the effect of interruptions, including similarity and complexity characteristics, on performance in a simulation of a procedural visual-manual assembly task. Findings indicate that complex interruptions may cause arousal that increases productivity in a primary assembly operation following an interruption. Similar interruptions both increase workload and time required to resume a primary assembly operation following an interruption. Although some of the results we obtained suggest differential effects of interruption complexity and similarity, the behavior exhibited by participants can generally be explained by MFG theory. The goals associated with the different tasks need to be activated and reactivated throughout the task and differences in similarity and complexity of primary and interruption tasks lead to differences in how the goals are encoded, decay, and interfere with one another. In regard to the practical research questions we identified in our Problem Statement, findings suggest that while it is not ideal to interrupt a worker during an assembly operation, status updates or performance of mental calculations may be less disruptive than assembly rework or repairs, which should be saved for the end of a workshift or an ongoing assembly operation.
