“…For other similar demonstrations of hysteresis in human locomotion seeAbdolvahab (2014Abdolvahab ( , 2015;Hreljac (1995);Hreljac, Imamura, Escamilla, and Edwards (2007);Li (2000); andTurvey, Holt, LaFiandra, and Fonseca (1999).3 With regard to the observation of negative hysteresis in the study byGetchell and Whitall (2004), it can be argued that in their experiment the constraint on the system was intentional rather than cognitive; the intentional switching between symmetric and asymmetric gaits (e.g., walk-togallop or run-to-gallop) can be taken as acting as a constraint on the system that can alter symmetries at the level of perception-action cycle (seeAbdolvahab, Carello, Pinto, Turvey, & Frank, 2015).…”
