Bimanual Coordination Learning with Different Augmented Feedback Modalities and Information Types.

Chiou SC, Chang EC - PLoS ONE (2016)

Bottom Line: Previous studies have shown that bimanual coordination learning is more resistant to the removal of augmented feedback when acquired with auditory than with visual channel.The results showed diverse performance change after practice when the feedback was removed between Lissajous and the other two rhythmic groups, indicating that the guidance effect may be modulated by the type of information provided during practice.Moreover, significant performance improvement in the dual-task condition where the irregular rhythm counting task was applied as a secondary task also suggested that lower involvement of conscious control may result in better performance in bimanual coordination.

ABSTRACT
Previous studies have shown that bimanual coordination learning is more resistant to the removal of augmented feedback when acquired with auditory than with visual channel. However, it is unclear whether this differential "guidance effect" between feedback modalities is due to enhanced sensorimotor integration via the non-dominant auditory channel or strengthened linkage to kinesthetic information under rhythmic input. The current study aimed to examine how modalities (visual vs. auditory) and information types (continuous visuospatial vs. discrete rhythmic) of concurrent augmented feedback influence bimanual coordination learning. Participants either learned a 90°-out-of-phase pattern for three consecutive days with Lissajous feedback indicating the integrated position of both arms, or with visual or auditory rhythmic feedback reflecting the relative timing of the movement. The results showed diverse performance change after practice when the feedback was removed between Lissajous and the other two rhythmic groups, indicating that the guidance effect may be modulated by the type of information provided during practice. Moreover, significant performance improvement in the dual-task condition where the irregular rhythm counting task was applied as a secondary task also suggested that lower involvement of conscious control may result in better performance in bimanual coordination.

pone.0149221.g006: Performance change after feedback removal.

Mentions: To examine whether different types of augmented feedback applied during the practice phase would result in different performance change upon their removal, a Group × feedback availability (with and without augmented feedback) mixed-design ANOVA was conducted on the RMSE of the last block of practice and the immediate no-feedback transfer test. Main effects for Group, F(2,19) = 5.54, MSE = 55.20, p = .013, η2 = .01, feedback availability, F(1,19) = 33.42, MSE = 26.33, p < .001, η2 = .22, and the Group × feedback availability interaction F(2,19) = 49.66, MSE = 26.33, p < .001, η2 = .66, were all significant. Simple main effect of feedback availability demonstrated significant performance deterioration in the Lissajous group, with mean difference of 29.00 degrees, t(7) = 8.48, p < .001, but not in the Tone group, mean difference = 5.71 degrees, t(6) = 2.24, p = .067. Surprisingly, the results showed significant performance improvement in the Color group when the feedback was removed, mean difference = -7.81 degrees, t(6) = -5.97, p = .001 (Fig 6). Looking at the interaction in the other way, post hoc comparisons also showed that while the Lissajous group outperformed the other two groups at the end of practice (both ps < .001), they performed significantly worse than the Color group (p = .021), and did not significantly differ from the Tone group (p = .571) in the immediate transfer test. The Color group did not differ from the Tone group either at the end of practice (p = .089) or in the immediate no-feedback condition (p = .367).
