“…In contrast to previous studies (Viviani 2002;Viviani and Mounoud 1990;Viviani et al 1987) but similar to findings of Wann et al (1988), the typical curvature-velocity relation as predicted by the 2/3 power law seems to be altered after motor training.…”

Few studies have reported direct effects of motor learning on visual perception, especially when using novel movements for the motor system. Atypical motor behaviors that violate movement constraints provide an excellent opportunity to study action-to-perception transfer. In our study, we passively trained blindfolded participants on movements violating the 2/3 power law. Before and after motor training, participants performed a visual discrimination task in which they decided whether two consecutive movements were same or different. For motor training, we randomly assigned the participants to two motor training groups or a control group. The motor training group experienced either a weak or a strong elliptic velocity profile on a circular trajectory that matched one of the visual test stimuli. The control group was presented with linear trajectories unrelated to the viewed movements. After each training session, participants actively reproduced the movement to assess motor learning. The group trained on the strong elliptic velocity profile reproduced movements with increasing elliptic velocity profiles while circular geometry remained constant. Furthermore, both training groups improved in visual discrimination ability for the learned movement as well as for highly similar movements. Participants in the control group, however, did not show any improvements in the visual discrimination task nor did participants who did not acquire the trained movement. The present results provide evidence for a transfer from action to perception which generalizes to highly related movements and depends on the success of motor learning. Moreover, under specific conditions, it seems to be possible to acquire movements deviating from the 2/3 power law.

“…Viviani and Stucchi (1992a) conducted experiments on the perception of curvilinear movement trajectories of a single point light. They found that trajectories obeying the kinematics of biological motion (expressed by an equation in which speed varies with the degree of curvature) were perceived as having uniform speed, even though the variations in speed in fact exceeded 200% (see also Viviani, Baud-Bovy, & Redolfi, 1997;Viviani & Mounoud, 1990;Viviani & Stucchi, 1989). These findings suggest that curvilinear movements are perceived, not in terms of actual changes in velocity, but in terms of wholistic gestures, which appear smooth and uniform when executed as a biological system would articulate them.…”

Perceiving imitatible stimuli: Consequences of isomorphism between input and output.

For more than a century, psychologists have been intrigued by the idea that mental representations of perceived human actions are closely connected with mental representations of performing those same actions. In this article, connections between input and output representations are considered in terms of the potential for imitation. A broad range of evidence suggests that, for imitatible stimuli, input and output representations are isomorphic to one another, allowing mutual influence between perception and motoric planning that is rapid, effortless, and possibly obligatory. Thus, the cognitive consequences of imitatibility may underlie such diverse phenomena as phoneme perception; imitation in neonates; echoic memory; stimulus-response compatibility; conduction aphasia; maintenance rehearsal; and a variety of developmental and social activities such as language acquisition, social learning, empathy, and monitoring one's own behavior.

“…It has been suggested (Hoffman & Flinchbaugh, 1982) that these motor schemes are instrumental for providing a veridical three-dimensional (3D) interpretation of the retinal images. Moreover, further evidence of a motor component in the interpretation of visual information has come from the results of two experiments on visuomanual pursuit tracking (Viviani, Campadelli, & Mounoud, 1987;Viviani & Mounoud, 1990), which show that it is virtually impossible to accurately pursue two-dimensional (2D) targets that do not comply with certain regularities that characterize biological motions.…”

Six experiments demonstrate a visual dynamic illusion. Previous work has shown that in 2dimensional (2D) drawing movements, tangential velocity and radius of curvature covary in a constrained manner. The velocity of point stimuli is perceived as uniform if and only if this biological constraint is satisfied. The illusion is conspicuous: The variations of velocity in the stimuli exceed 200%. Yet movements are perceived as uniform. Conversely, 2D stimuli moving at constant velocity are perceived as strongly nonuniform. The illusion is robust: Exposure to true constant velocity fails to suppress it. Results cannot be explained entirely by the kinetic depth effect. The illusion is evidence of a coupling between motor and perceptual processes: Even in the absence of any intention to perform a movement, certain properties of the motor system implicitly influence perceptual interpretation of the visual stimulus.
