“…Error in performance was lower with augmented feedback than with no feedback signal. The advantage of augmented feedback likely arises from a more salient representation of relative timing information than is available during spontaneous performance (Bogaerts et al, 2003;Gonzales et al, 2010;Hessler et al, 2010;Roerdink et al, 2005). The observed benefit of augmented feedback for inphase performance is different from previous coordination results.…”

“…The displays were based on those used in previous investigations on relative phase perception (Bingham et al, 1999;Bingham et al, 2001;Zaal et al, 2000), except that motion in the displays was not simulated. Instead, participants' movement and breathing controlled motion of balls in the displays in real time (see also Gonzales et al, 2010;Hessler et al, 2010). Participants performed inphase and antiphase patterns between movement and breathing.…”

“…Upward-downward motion of a ball was compatible with forward-backward arm movement, whereas inflation-deflation of a balloon was compatible with inhalation-exhalation. In another study, Gonzales, Hessler, and Amazeen (2010) investigated whether differences in the visual perception of ratios were necessary for participants to differentiate the performance of ratios. Simple ratio performance was more stable than complex ratio performance when participants used displays in which feedback for different patterns looked different (because the performed ratio was depicted) but not when feedback for different patterns looked the same (because proximity to the target ratio was depicted).…”

The purpose of this study was to see how motor-respiratory coordination could improve with augmented visual feedback. Participants performed inphase and antiphase patterns between movement and breathing. When the target pattern was performed properly, balls in a feedback display either moved up and down together (inphase feedback) or opposite each other (antiphase feedback). Relative phase performance was less variable in the augmented feedback conditions than in a no display control condition. Within the augmented feedback conditions, variability was lower with inphase feedback than antiphase feedback. Cross-recurrence analysis was used to determine whether other changes occurred on shorter time scales. On cross-recurrence measures, performance was more variable with inphase feedback than in the control condition and with antiphase feedback. Those results suggest that, with inphase feedback, participants were able to achieve more stable overall relative phase patterns using small within-cycle trajectory changes. Those small changes were possible because the balls in the inphase feedback display were grouped by common fate. That perceptual organization made it possible for participants to see slight mismatches between movement and breathing and control coordination accordingly.

“…Synergies are webs of constraints that limit how the body can change in coordination. Respiratory and cardiovascular processes change together with a change of locomotor gait, for example, ensuring the right amount of oxygen to the cells at the right time (e.g., Gonzales et al, in press ). Behavioral processes in a skilled tennis player are constrained to run for the ball and make forehand shots, backhand shots, and to serve and return serves.…”

Much effort has gone into elucidating control of the body by the brain, less so the role of the body in controlling the brain. This essay develops the idea that the brain does a great deal of work in the service of behavior that is controlled by the body, a blue-collar role compared to the white-collar control exercised by the body. The argument that supports a blue-collar role for the brain is also consistent with recent discoveries clarifying the white-collar role of synergies across the body’s tensegrity structure, and the evidence of critical phenomena in brain and behavior.

“…Indeed, they imposed a particular frequency ratio to participants and observed a loss of stability when frequency increased, leading to transition toward more stable regions of synchronization [31] . Studies by Temprado et al [6] , Villard et al [33] and Gonzales et al [34] suggested that the nonlinear coupled-oscillators model could also be applied to study LRC. Hessler et al [35] observed a stability difference in arm-respiration multi-frequency ratios, with ratios of low-order levels in the Farey tree being more stable than ratio of higher-order levels.…”

Sound Stabilizes Locomotor-Respiratory Coupling and Reduces Energy Cost

A natural synchronization between locomotor and respiratory systems is known to exist for various species and various forms of locomotion. This Locomotor-Respiratory Coupling (LRC) is fundamental for the energy transfer between the two subsystems during long duration exercise and originates from mechanical and neurological interactions. Different methodologies have been used to compute LRC, giving rise to various and often diverging results in terms of synchronization, (de-)stabilization via information, and associated energy cost. In this article, the theory of nonlinear-coupled oscillators was adopted to characterize LRC, through the model of the sine circle map, and tested it in the context of cycling. Our specific focus was the sound-induced stabilization of LRC and its associated change in energy consumption. In our experimental study, participants were instructed during a cycling exercise to synchronize either their respiration or their pedaling rate with an external auditory stimulus whose rhythm corresponded to their individual preferential breathing or cycling frequencies. Results showed a significant reduction in energy expenditure with auditory stimulation, accompanied by a stabilization of LRC. The sound-induced effect was asymmetrical, with a better stabilizing influence of the metronome on the locomotor system than on the respiratory system. A modification of the respiratory frequency was indeed observed when participants cycled in synchrony with the tone, leading to a transition toward more stable frequency ratios as predicted by the sine circle map. In addition to the classical mechanical and neurological origins of LRC, here we demonstrated using the sine circle map model that information plays an important modulatory role of the synchronization, and has global energetic consequences.
