Abstract This study examined the effect of instructions and feedback on the integration of two tasks. Task-integration of covarying tasks are thought to help dual-task performance. With complete task integration of covarying dual tasks, a dual task becomes more like a single task and dual-task costs should be reduced as it is no longer conceptualized as a dual task. In the current study we tried to manipulate the extent to which tasks are integrated. We covaried a tracking task with an auditory go/no-go task and tried to manipulate the extent of task-integration by using two different sets of instructions and feedback. A group receiving task-integration promoting instructions and feedback (N = 18) and a group receiving task-separation instructions and feedback (N = 20) trained on a continuous tracking task. The tracking task covaried with the auditory go/no-go reaction time task because high-pitch sounds always occurred 250 ms before turns, which has been demonstrated to foster task integration. The tracking task further contained a repeating segment to investigate implicit learning. Results showed that instructions, feedback, or participants’ conceptualization of performing a single task versus a dual task did not significantly affect task integration. However, the covariation manipulation improved performance in both the tracking and the go/no-go task, exceeding performance in non-covarying and single tasks. We concluded that task integration between covarying motor tasks is a robust phenomenon that is not influenced by instructions or feedback.

Perceptual Styles

Differences in dual-task performance by field-dependent and field-independent college students were investigated. The perceptual styles of the 102 subjects were determined by their performance on the Rod-and-Frame Test. Dual-task performance required the subjects to perform concurrently a central tracking task and a peripheral light-detection task. The effect of stress on dual-task performance was examined by employing three widely differing levels of tracking task difficulty. Three sets of instructions varied the relative importance of the two tasks within the dual-task situation. Both manipulation of task difficulty and instructional set had powerful effects on performance. However, performance differences among subjects with differing perceptual styles were found only on the central tracking task, with field-independent subjects consistently outperforming field-dependent ones. The results are discussed in terms of the theoretical basis for the perceptual style of field-dependence/field-independence as well as the potential value of this dimension in dual-task situations.
