Abstract:

Beyond specific conflicts between tasks that are obviously similar (e.g. 2 verbal tasks), is there a general limitation on how much can be done simultaneously? In two experiments, we examined dual task combinations designed to avoid known sources of specific interference. Under these circumstances, the general factor model predicts consistency in the pattern of results. Tasks should be ordered in demands on the general factor as measured by interference with concurrent tasks; this order should be the same for any concurrent task used to measure it. This prediction was confirmed in both experiments, each involving 12 interrelated dual task combinations.
