Intentional Switching Between Bimanual Coordination Patterns in Older Adults: Is It Mediated by Inhibition Processes?

Abstract

Frontiers in Aging Neuroscience | www.frontiersin.org February 2020 | Volume 12 | Article 29 Temprado et al. Bimanual Switchingat least to trigger the early phase of switching. They also support the hypothesis that inhibition processes are more involved in maintaining the AP pattern and switching to the IP pattern. Finally, age-related changes in switching times seem to be prominently mediated by alterations of inhibition processes.

Cognition and action: a latent variable approach to study contributions of executive functions to motor control in older adults

“…We did not find evidence for inhibitionspecific contributions to complex motor performance in this sample. In the correlated factors model, the inhibition factor showed a positive, but non-significant relationship with motor performance, which is broadly consistent with earlier reports based on findings on a single inhibition task [65]. In the bifactor model, the "inhibition"-specific factor mainly captured variability in NST (standardized factor loading: .59) and less from other inhibition tasks (AT: .02, SST: .38), and hence might not have reflected inhibition optimally.…”

Can Exergames Be Improved to Better Enhance Behavioral Adaptability in Older Adults? An Ecological Dynamics Perspective

“…On the one hand, cognition modulates functional interactions between the different components of the BMBS, thereby allowing to shape the emerging behavioral patterns [e.g. (Zanone and Kelso, 1992;Monno et al, 2002;Taylor et al, 2018;Temprado et al, 2020)]. On the other hand, cognition supports the attunement of behavior to the perceptual-motor workspace by supervising how the individual does something somewhere (Araujo, 2009), that is, how it attains a functional relationship with the world by virtue of changes in information-movement coupling [e.g.…”

“…It can be directly or indirectly assessed through dynamical markers (Sleimen-Malkoun et al, 2014), as, for instance, directly through (i) the repertoire of behavioral patterns (Sleimen-Malkoun et al, 2013Temprado et al, 2020) and/or of execution strategies [e.g. (Poletti et al, 2016)] that are available and effectively used by the performer; and (ii) the dynamics of switching between behavioral patterns and strategies that are observed when task constraints are increased [e.g.…”

“…(Poletti et al, 2016)] that are available and effectively used by the performer; and (ii) the dynamics of switching between behavioral patterns and strategies that are observed when task constraints are increased [e.g. (Kelso, 1984;Temprado et al, 2020)]. Moreover, adaptability can also be indirectly assessed through the complex structure of the non-linear fluctuations of the output of the system under consideration [e.g.…”

Comparison of Three Physical—Cognitive Training Programs in Healthy Older Adults: A Study Protocol for a Monocentric Randomized Trial

“…They showed larger activation of the prefrontal areas during motor tasks in older adults, which suggested that executive functions become more involved in complex movement control (e.g., interlimb coordination) compared to younger subjects [ 20 , 21 ]. Convergent evidence also suggested a strong link between age-related alteration of executive functions and deficits in gait, posture [ 22 ], and bimanual coordination [ 23 ]. According to this theoretical framework, it can be hypothesized that, in older adults, motor skills training involves more cognitive resources than in younger adults and could, therefore, be particularly appropriate to improve cognitive functions [ 24 ].…”
