It is generally assumed that performance impairment in dual-task studies reflects the degree to which the two tasks draw upon common cognitive processes or mechanisms. The present paper reports an attempt to identify and categorise the cognitive functions that underlie interference effects in dual-task studies. The extant literature was reviewed, and a short-list of twelve tasks used commonly in dual-task studies was identified. A task similarity matrix was constructed that plotted the degree of interference between task pairs. Based on the similarity matrix a first estimate of the positions of the selected tasks in Euclidean (interference) space was made and clusters of tasks identified. Results suggest that the common modular dichotomy between verbal and spatial resources is necessary but not sufficient to explain the findings. |
