Comparative Analysis Of ERP Characteristics Of Pre-attention Processing Of Athletes In Different Sports Groups

Preattentional processing is the unconscious automatic processing activity of the brain,which is the basis of human perception and cognitive activities.It is also the automatic awareness of non-attentional stimulus input,which can prepare sensory input resources for concentrated attentional processing.At present,psychological research on attention,from attention before attention,from hearing to vision and other related research researchers are constantly digging,and into the field of brain science,using precise instruments and equipment to explore the deep mechanism of attention and pre-attention.Preattentional processing is the primary stage of attentional processing.Domestic scholars have conducted a series of studies from auditory preattentional processing to visual preattentional processing and then to visual emotional information preattentional processing,in which the mismatched negative wave(MMN)is the only objective index to test the whole stage of preattentional processing [41].In foreign studies,they mainly focus on the fields of psychiatry and psychology,whose monitoring indicators are also mismatched negative waves.Note before processing as an important stage,concentrated attention processing is relatively less research in the field of sports mainly adopts expert-novice paradigm with oddball paradigm or across the channel delay reaction Fan Shixiang union,but the research is not comprehensive,and in different Xiang Qun athletes attention before processing if there is a difference is not obvious conclusions through data.The purpose of this study is to explore whether there are differences in the pre attention processing mechanism of athletes in different categories,different sub categories and different sub categories from the perspective of psychophysiology,and the possible reasons for the differences.On the basis of previous studies,this study adopts the experimental paradigm of "cross channel delayed response" to edit the experimental program.In terms of the selection of visual and auditory channels,this experiment mainly discusses the differences between the pre visual attention processing of athletes in different event groups,so the subjects are required to pay attention to the stimulation of auditory channels,and begin to respond to the command sound The auditory stimulus made the key response,ignoring the visual stimulus.The whole experiment consists of two blocks and 320 tracks,which can rest between blocks.In the process of the experiment,the subjects are required to pay attention according to the requirements of the experiment and complete the experiment carefully.Conclusion of this study:(1)The feasibility of the experimental procedure is verified by analyzing the behavior data of athletes in different events.(2)At the FZ point of frontal region,the skill-oriented athletes allocate more cognitive resources in the cognitive process than the other athletes,and their cognitive function is stronger.The cognitive processing time and speed of the SPC-oriented athletes were longer and slower.There was no significant difference in the PZ,P3,P4,OZ,O1 and O2 of the parietal and occipital regions.(3)Among the athletes of the same category and different subcategories,the athletes of the physical fitness dominant category are in the top P4 position,and the speed athletes allocate more cognitive resources than the endurance athletes in the cognitive process,and the cognitive function is stronger.The cognitive processing speed of speed athletes was faster and the time was shorter than that of fast strength and endurance athletes.Athletes in the skill dominant category were at the OZ position in the occipital area.Compared with those in the net antagonist and the combat antagonist,the athletes in the same field allocated more cognitive resources and had stronger cognitive function in the cognitive process.(4)The amplitude of negative wave induced by visual mismatching in the parietal occipital region was as follows: speed > difficult > accuracy > in-field > rotation offensive and defense > endurance > fast strength > combat antagonism > net antagonism;The incubation period was as follows: accuracy > difficult > net antagonism > same field antagonism > fast strength > fighting > speed > rotation attack and defense antagonism > endurance.(5)From the perspective of different Xiang Qun athletes,the cross channel response of innovative paradigm for athletes of visual attention before processing is analyzed and discussed,the experimental results by combining with previous related theory,and according to the characteristics of the Xiang Qun proper explains different Xiang Qun athletes exist differences in visual attention before processing.
