The Effects Of Badminton Playing On The Global Motion Perception Of Adults And Its Mechanism

The global motion perception refers to the ability which integrates local motion signals to form an global perception to obtain information such as speed and direction.As an important aspect and step for visual perception,the global motion perception has been an important field of research in psychology.However,most of the previous researches still the fields of basic research and developmental research.Although some studies have applied the global motion perception to the rehabilitation training of patients and even made gratifying progress in the field of action video games,the effects of badminton playing which has more socially significance and ecological validity on global motion perception of adults and its internal mechanisms is still unclear.At the same time,existing studies are mostly cross-sectional studies which could not exclude the effects of innate factors.To address these issues,the present study combined cross-sectional with longitude study to systematically examine the effects of badminton playing experiences on the individual's global motion perception and its underlying mechanisms.Experiment 1a was a cross-sectional study that investigated the differential global motion perception between professional badminton players and novices.The paradigm used to study global motion perception in the present study was classical random-dot kinematograms(RDKs),which has four motion types and eight motion directions(e.g.,from left to right,from up to down,radial and rotational).In order to exclude the effects of innate factor,experiment 1b designed a longitude study to investigate the effects of motor training in adults.In this study,young adults with litter ball experience were assigned randomly to the experiment group and the control group.The experimental group was asked to attend a 12-week's badminton training.The RDKs paradigm was tested before and after the trainings for both of the groups.In experiment 2,the classical random-dot kinematograms was transformed into two performances levels and eight speeds levels of dot which as the external noise to investigated the differential global motion perception between professional badminton players and novices.At the same time,the results were fitted with the perceptual template model(PTM)to explore its internal mechanism.Taken together,the findings in the present study suggests that badminton training enhanced the abilities of the global motion perception,and this perceptual learning effect of the global motion perception ability can be transferred from a special badminton sports scene to a general random-dot kinematograms task.Further,the global motion perception ability of badminton players was significantly better than that of ordinary adults under high-speed conditions,but not low-speed conditions.Using the PTM approach,we demonstrated that professional badminton players developed better perceptual templates so that external noise can be better excluded.The results have a great guiding significance for the training of the global motion perception.
