The efficiency of interruption handling in free and forced switching tasks
Abstract
An ecologically valid experimental study of the effect of switching mode for the efficiency of interruption handling is presented. Two switching modes, free switching and forced switching, were used in the study. Free switching permits the subject to perform some preparatory activity before switching to the interrupting task, whereas forced switching makes any kind of preparation very difficult. It is shown that free switching makes handling of complex interruptions more efficient. In addition, an analysis of mean fixation duration at different stages of interruption handling shows that differences in interruption handling efficiency are paralleled by differences in cognitive workload. Implications for the notion of different interruption handling strategies which are aimed at optimizing cognitive workload are discussed.
