In the perceptual evaluation tasks, the participants were asked to perform two perceptual performance tests that distinguished which hand was leading and what pattern they had performed. The perceptual evaluation task was replicated the way that is used to Maslovat et al (2010) study. Following each scanning trial on day1 and 3, participants were instructed to discriminate the leading arm and coordination pattern. In the current study, the models showed a significant improvement in perceptual evaluation for both the pattern and hand discrimination, while the controls failed to yield an improvement in perceptual evaluation. Further, the observers showed a significant improvement in the pattern discrimination and leading hand discrimination …show more content…
The observers paired with physical models that practiced the required pattern with animation of inverted pendulums that defined the 90 pattern with a right-hand lead (Figure 1A) were able to discriminate the practiced pattern as well as the physical practice model, and more accurately than the control group. They suggested that visual experience alone is sufficient to show an improvement in perceptual discrimination. Previous research revealed that the perception of bimanual patterns reflects the production of those patterns. For instance, in-phase ( = 0˚) and anti-phase ( = 180˚) are perceived as the most coordinated patterns, while other relative phase patterns, such as = 90˚, are perceived as less coordinated based on visual information (G. P. Bingham, R. C. Schmidt, & F. T. Zaal, 1999). Recently, in a series of studies conducted by Buchanan and colleagues (Buchanan, 2015; John J Buchanan, Jorge Ramos, & Nina Robson, 2015) provide evidence that ability to perceive differences in movement patterns directly linked to production of different coordination patterns. The participants performed single-limbs multi-joint rhythmic movement and then were asked to rate the performance proficiency by themselves. In-phase and
