A tutorial on dose-response profiles applied to crew rowing https://socibracom.com/bjmb/index.php/bjmb/article/view/398 <p style="font-weight: 400;">Many models of motor performance acknowledge that adapting to stressors plays a major role in how we move. However, most models lack a precise conceptualization of the way in which stress-response dynamics unfold. To fill this void, we first present popular models from the domain of biology and psychology which argue that the impact of a stressor depends on its dose. Next, we provide a tutorial using the example of crew rowing to demonstrate how these models can be scaled to human motor performance. In this example, the dose of the stressor is varied by target times for several 500 m races and the response variable represents the crew coordination. Specifically, we discuss how the necessary parameters can be determined a priori and how the data can be analyzed to pinpoint the exact dose-response relationship. These strides are necessary for developing more comprehensive theories of motor performance and engage in cross-disciplinary research on the impact of stressors.</p> Yannick Hill Laura S.

His research and thoughts influenced uncountable scholars over the last 50 years, and his kindness and dedication were examples to many. Through the reflections of esteemed colleagues and former students gathered in this Special Issue of the Brazilian Journal of Motor Behavior, we gain insights into the profound influence of Michael Turvey on motor behavior and beyond.</p> Vitor L.

We show, in particular, how this approach fits the philosophical traditions of Merleau-Ponty, the theory of control with spatial referent coordinates, the principle of abundance, and the concept of performance-stabilizing synergies using the uncontrolled manifold hypothesis.</p> <p style="font-weight: 400;"><strong>RESULTS:</strong> Currently, this scheme of motor control has been applied successfully in studies of a variety of effectors, from single motor units to the whole body, a variety of tasks, and various populations. It led to the discovery of new phenomena and new interpretations of known phenomena. It has been productive in studies of neurological patients offering new understanding of some of the common pathologies (e.g., spasticity) and new tools for early diagnosis of various subcortical disorders and monitoring treatment effects.</p> <p style="font-weight: 400;"><strong>CONCLUSION:</strong> Currently, this field faces a number of challenges including the following: Mapping steps in the hierarchical control scheme on neurophysiological structures and circuits, understanding the relative role of intra-muscle (spinal) and multi-effector (supraspinal) synergies, expanding studies of movements in intact animals and animal preparation, and moving beyond the current scheme to fields traditionally associated with psychology. Just like the current scheme represents moving “outside the box” of classical mechanics, a step outside the current thinking is needed.</p> Mark L.

Mike Turvey was able to educate the next generation of students and influence the thinking of many outstanding researchers by focusing on a multidisciplinary approach to ecological psychology in which organisms directly perceive sensory stimuli and evaluate them depending on actions they can accomplish in the environment (Gibson 1968). This, “affordance principle” is applied to all biological kingdoms from a single cell amoeba to multi-celled organisms. Some other essential ideas in behavioral neuroscience advanced by Turvey are considered.</p> Anatol Feldman Copyright (c) 2024 Anatol Feldman https://creativecommons.org/licenses/by-nc-nd/4.0 2023-12-22 2023-12-22 17 6 294 296 10.20338/bjmb.v17i6.413 Michael Turvey: A Personal Tribute https://socibracom.com/bjmb/index.php/bjmb/article/view/408 <p>Michael Turvey revolutionized the study of perception and action. In this personal tribute, I summarize his most important contributions from my perspective. The contributions start with information-processing psychology and then turn to ecological and dynamical-systems research. My work, like that of many others, was significantly affected by Turvey’s insights and charisma. I review studies of my own that particularly bore the mark of Turvey and his colleagues.</p> David A.

There are multiple research programs that I have carried out over the last twenty-five years that have all been influenced by the ecological and dynamical systems accounts that were pioneered by Michael Turvey. In this article I will highlight significant developments in 1) contribution of movement to timing and time perception 2) the contribution of the motor system in beat perception in music 3) postural sway dynamics 4) the role of detuning in bimanual coordination and finally 5) the control of unstable objects. In all these lines of work, I will specifically provide instances of how Michael Turvey’s ideas inspired subsequent research in my lab and elsewhere.</p> <p> </p> Ramesh Balasubramaniam Copyright (c) 2024 RAMESH BALASUBRAMANIAM https://creativecommons.org/licenses/by-nc-nd/4.0 2023-12-22 2023-12-22 17 6 315 319 10.20338/bjmb.v17i6.416 More than science: A systems approach inspired by Michael T. Turvey https://socibracom.com/bjmb/index.php/bjmb/article/view/411 <p style="font-weight: 400;">This year, we lost a giant in the field of perception and action, Michael T. Turvey. This special issue is dedicated to the impact that he made on his students and the field. I learned about ecological psychology just as I was headed to graduate school in 1990. Through Michael's teachings and my own academic career that followed, I recognized that the inseparability of organism and environment that was fundamental to ecological psychology was part of the larger story of a systems perspective that itself helped to frame questions of causality from Aristotle and the problematic division of subject and object inherited from Descartes. In this mini review, I identify fundamental concepts in systems science from an academic perspective, but I extend that same reasoning to life beyond science. Together with his wife, Claudia Carello, who was also the director of the Center for the Ecological Study of Perception and Action (CESPA) at the University of Connecticut, Michael taught, mentored, and cared for his students within the same systems framework. It is that broader lesson for how to teach and mentor students that I offer to honor his memory today.</p> Polemnia G.

Finish. Publish.”— was on Michael Turvey’s office door at the Center for Ecological Study of Perception and Action. Michael heeded this admonition, publishing hundreds of scientific papers and chapters over the course of his fifty-year career. But Michael always believed that his true life’s work was as a mentor and educator. Moreover, Michael also believed that the time and energy spent celebrating successes ought to outweigh that spent on bemoaning failures. And so, Michael lived by a revised version of Faraday’s admonition—“Work. Finish. Publish. Teach. Celebrate.”</p> Jeffrey B.

Turvey: A tribute to an extraordinary teacher & mentor https://socibracom.com/bjmb/index.php/bjmb/article/view/415 <p style="font-weight: 400;">This essay is a tribute to Michael T. Turvey, my PhD mentor at the Center for the Ecological Studies of Perception and Action (CESPA), University of Connecticut, and a distinguished figure in the field of motor behavior research. My narrative aims to showcase the exceptional qualities of Turvey as a teacher and mentor and share the insights I gained from him in the specific context of his emblematic action course. I hope these insights will enlighten and inspire others as they have me, thereby perpetuating his legacy.</p> <p style="font-weight: 400;"> </p> Paula L. Silva Copyright (c) 2024 Paula L.
