| Popis: | OCCUPATIONAL APPLICATIONS This study investigated the effects of a multimodal dual-task paradigm (balance and cognitive tasks) on overall mental workload. The balance task did not affect the performance of the cognitive task, and the presence of the cognitive task led to better balance performance with unstable seating. Simultaneously, measures of overall mental workload showed a general increase when the cognitive task was added and, in some cases, when the balancing task became harder (more unstable). These results generate two important implications. First, the performance levels of two multimodal tasks being done concurrently are insufficient to explain the overall workload in the system. Even if performance is not negatively (or even positively) affected initially, workload increases and may approach or reach overload. Second, any single measure of performance or workload taken in situ might very well be insufficient to explain effectively the way an individual is interacting with their multitasking ... |
