Automatisierung motorischer Fertigkeiten / Augmented feedback and motor automatization - Effects of feedback practice design on dual-task cost reductions
In motor learning, automatization apparently depends on the ways augmented feedback is designed (e.g., Agethen & Krause, 2016). According to behavioral (Masters & Maxwell, 2004; Explicit-Hypothesis Testing) and neurophysiological perspectives (Holroyd & Coles, 2002; Seidler et al., 2013; Feedback-Related Negativity), error feedback is supposed to induce attention-dependent cognitive processes for subsequent error corrections. This could help to reduce errors, but might also impede motor automatization. In contrast feedback with positive valence is supposed to facilitate dopamine-mediated long-term potentiation of neural loops that led to the successful movement execution. This refers to the reward-prediction error hypothesis of dopamine (see Glimcher, 2011). In a series of experiments, we hypothesized, that automatization is facilitated by a low error feedback frequency, a larger tolerated error-bandwidth, serving as qualitative positive feedback, predominant positive valence of normative feedback, as well as a low visual gain.
