The Planning Performance Trade-Off in Use of Textual and Illustrated Procedural Instructions.
This study explored how, and what type of, procedural instructions influence a trade-off between planning and performance. There is a trade-off if longer planning time shortens performance time, improves performance efficiency, and improves accuracy. The relative effectiveness of nine combinations of illustrated and written instructions for an assembly task were compared. Three time measures were used: (1) total session time; (2) planning time; and (3) performance time. Other performance measures were efficiency and accuracy. It was concluded that there was a trade-off between combined instructions versus totally illustrated or totally written instructions. The degree of operational information in totally illustrated or totally written instructions also influenced planning and performance, but in different ways. Accuracy was less affected by the instructional variations than by other comprehensive measures because sufficient clues appeared in the core information of all instructional variations. (JD)
