“…Apart from these new Wndings we replicated some well known phenomena from the literature. That is, reaction times and movement times were longer in bimanual trials compared to unimanual trials (e.g., Kelso et al 1979;Jackson et al 2002;Mason and Bryden 2007), and interlimb coupling was higher when moving in symmetry than in asymmetry (e.g., Swinnen et al 1991;Carson 1995;Semjen et al 1995).…”

“…These interference eVects were especially obvious when nonhomologous muscle pairs were activated (Li et al 2004). Ample studies showed an increased stability of arm movements in the symmetric mode (both hands/arms moving mirror-symmetrically with respect to the longitudinal axis of the body) compared to arm movements in the asymmetric mode (both hands/arms moving alternating with respect to the longitudinal axis of the body) (Byblow et al 1994;Semjen et al 1995;Swinnen et al 1997Swinnen et al , 1998Li et al 2004).…”

Combined effects of planning and execution constraints on bimanual task performance

In this study we investigated the relative impact of planning and execution constraints on discrete bimanual task performance. In particular, in a bimanual CD-placement task, we compared people's preference to end movements comfortably with their preference to move symmetrically. In "Experiment 1" we examined the degree of interlimb coupling as participants repositioned two CDs in a CD rack by simultaneously moving their arms mirrorsymmetrically or asymmetrically into comfortable or uncomfortable end postures. Interlimb coupling was stronger when the arms moved symmetrically towards uncomfortable end postures. In "Experiment 2" participants were asked to realize speciWc end orientations of the CDs but they were free to choose an initial grip type and subsequent direction of forearm rotation. Surprisingly, the participants did not move their arms symmetrically but preferred to end in a comfortable posture with their right hand but not with their left hand. We conclude that in discrete bimanual task performance the tendency to end movements in a comfortable posture dominates over the tendency to synchronously activate homologous muscle pairs. The lateralized end-state comfort eVect suggests a hemispheric specialization for motor planning.

“…For instance, phase transitions occur earlier for wrist abduction and adduction movements than for wrist flexion and extension movements (see note 3). At a more cognitive level, movements with compatible spatial codes are easier to perform than those in which such codes are incongruent (Franz, Zelaznik, & McCabe, 1991;Semjen, Summers, & Cattaert, 1995), independent of biomechanics. Such codes may be perceptual in nature (Mechsner, 2004a(Mechsner, , 2004bMechsner et al, 2001; see also Kunde & Weigelt, 2005), and/or they may reflect interactions associated with response selection (Ivry et al, 2004).…”

Constraints underlying bimanual coordination have traditionally been explained by dynamic interactions between the effectors. However, the present experiments demonstrate that a fundamental constraint on bimanual performance is the manner in which task goals are represented. In Experiment 1, participants vocalized during in-phase and anti-phase bimanual movements. As expected, most participants spontaneously exhibited temporal coupling between the manual and vocal responses. However, the form of coupling differed for the in-phase and anti-phase conditions. For anti-phase movements, there was a strong bias to produce two vocalizations per cycle; for in-phase movements, participants were equally likely to produce one or two vocalizations per cycle. We hypothesized that the spontaneous vocalizations probed the cognitive representation of the task, and the results indicated that anti-phase movements did entail a more complex event structure than in-phase movements did. In Experiment 2, we manipulated the event structure by having participants vocalize either once or twice per hand cycle. As predicted, coordination stability was reduced when the event structure was more complex.

“…As such, we have partial data (13 subjects) for right-handed tapping. However, nondominant left-hand movements have been reported to fluctuate more in the BP mode than those of the dominant right hand (Semjen et al, 1995;Aramaki et al, 2006). Thus, we calculated performance indices using left-hand tapping data for all 18 subjects and used it in the correlation analysis with brain activity.…”

In periodic bimanual movements, anti-phase-coordinated patterns often change into in-phase patterns suddenly and involuntarily. Because behavior in the initial period of a sequence of cycles often does not show any obvious errors, it is difficult to predict subsequent movement errors in the later period of the cyclical sequence. Here, we evaluated performance in the later period of the cyclical sequence of bimanual periodic movements using human brain activity measured with functional magnetic resonance imaging as well as using initial movement features. Eighteen subjects performed a 30 s bimanual finger-tapping task. We calculated differences in initiationlocked transient brain activity between antiphase and in-phase tapping conditions. Correlation analysis revealed that the difference in the anterior putamen activity during antiphase compared within-phase tapping conditions was strongly correlated with future instability as measured by the mean absolute deviation of the left-hand intertap interval during antiphase movements relative to in-phase movements (r ϭ 0.81). Among the initial movement features we measured, only the number of taps to establish the antiphase movement pattern exhibited a significant correlation. However, the correlation efficient of 0.60 was not high enough to predict the characteristics of subsequent movement. There was no significant correlation between putamen activity and initial movement features. It is likely that initiating unskilled difficult movements requires increased anterior putamen activity, and this activity increase may facilitate the initiation of movement via the basal ganglia-thalamocortical circuit. Our results suggest that initiation-locked transient activity of the anterior putamen can be used to predict future motor performance.
