Abstract

Findings from different areas suggest a beneficial impact of predictability on dual-task cost prevention and reduction, e.g. induced by perceptual predictability (Körding, & Wolpert, 2004) or implicit knowledge (Wulf & Schmidt, 1997). To test this several experiments were conducted examining the effects of a predictable environment in a tracking task. While in the first study perceptual predictability was created by providing visual and auditory information, the second study examined predictability in the light of self-generated implicit knowledge. It was hypothesized that both, perceptual cues as well as implicit learning, positively affect dual-task performance. Participants performed a manual pursuit tracking task following a red square with a joystickwhile concurrently responding to high-pitched sounds by pedal press and ignoring lowpitched tones. The tracking path consisted of three segments. In experiments manipulating perceptual predictability, all three segments were randomized throughout all trials trial, in implicit-learning manipulations a constant middle segment was presented. In a first step perceptual predictability was manipulated by displaying the tracking path ahead of the red target, in a second step the tones of the secondary task were presented as a sequencemanipulating auditory predictability. Third when knowledge was manipulated via the constant middle segment of the tracking path; an implicit group was not informed about the repeating segment, while the explicit group was. As expected both perceptual predictability as well as implicit and explicit knowledge lead to enhanced tracking performance indicating its beneficial effects for dual-task cost prevention and reduction.
