The Effect Of Global Motor Perception Level On Inhibition Function Of College Students

In the motion situation,the ability to integrate the moving trajectory of several local signals to form an overall "common destiny" subject to obtain the direction and speed of the target information is called global motion perception.In the process of extracting these relevant signals,individuals need to produce goal-oriented and relatively flexible behaviors,which can not be separated from the participation of individual response inhibition function.Reaction inhibition is a spontaneous behavior of the subject,which refers to the ability to actively suppress unnecessary,unimportant and irrelevant information after the perceptual goal is defined.Psychophysical and electrophysiological studies have suggested that there exists a postperceptual gate operated by the attentional mechanism to limit the access of the higher cortex to encoded motor signals,thus influencing the individual’s choice of target stimuli and processing of interference stimuli.In the field of competitive psychology,how to help athletes improve their executive control ability and keep their state stable has always been a hot issue.A series of previous studies on amblyopic children,ball players and e-sports players have shown that the level of overall motion perception can be improved through exercise.Therefore,whether the level of individual’s overall motion perception will affect their ability of response inhibition has attracted the attention of the author.Based on this question,this study took global motion perception as the starting point and used Stroop task,Flanker task and Go/ No Go task as the measurement paradigm of response inhibition to explore the relationship between global motion perception and inhibition function and its internal mechanism.In the preliminary experiment,the random lattice paradigm was used as the measurement paradigm of the overall level of motion perception,and the motor consistency threshold was used as the index.The subjects were divided into high ability group and low ability group,which were used as the grouping basis of the follow-up experiment.In Experiment 1,the Stroop task,Flanker task and Go/ No Go task were used to evaluate the high and low levels of global motion perception,respectively,in order to explore the different effects of global motion perception on the inhibition of habitual dominant response,resistance to irrelevant interference,and inhibition of newly formed dominant response.The results showed that :(1)In the Stroop experiment,when the familiar stimulus was inconsistent with the response to it,the high ability group performed better;(2)In the Flanker experiment,the accuracy rate of the high ability group was higher than that of the normal group,but the response time was also longer,which seemed to indicate that the overall motion perception ability could affect the individuals’ choice of key objects in problem processing.(3)In the GO/ NO GO experiment,the response time of the high ability group was significantly faster than that of the low level group,but there was no significant difference in the accuracy,which may be due to the task difficulty setting being too easy.Experiment 2 test was carried out on the stability of the whole motion perception,adding a stressful situation,using modified method to estimate the task as a source of stress,induced the subjects psychological stress,using random lattice model to measure the motion perception level subjects,the results show that although the stress will affect the accuracy of individual judgment and reaction speed,However,the group with high overall motion perception ability had faster self-regulation,and the speed and accuracy were significantly higher than those of the group with low ability.This indicates that the individual’s overall motion perception is relatively stable.
