Technical Field

The invention relates to the technical field of semantic recognition, in particular to a method, a system and instrument equipment for judging a motor ethical tendency based on cognitive nerves.

Background

The judgment of the ethical of the athlete refers to the thinking form that the athlete individual uses the existing ethical specification or standard to recognize the ethical phenomenon in the movement. The prior research in the field makes an important contribution to helping people to know the moral judgment of athletes, however, the prior research focuses more on the front cause and the rear effect of the moral judgment, and the further intensive research on the moral judgment is far from enough to stay on the front cause and the rear effect of the discussion. In order to provide new visual angles and scientific bases for improving the professional moral education of athletes, and also to help us to better understand the decision mechanism of moral judgment, revealing the cognitive neural mechanism of moral judgment has become a key problem to be solved in the research of the moral field.

From the research of the life field, moral judgment related research has become a hotspot of social cognitive nerve field research, and scholars mostly adopt a functional magnetic resonance imaging technology (fMRI) to examine the activation of brain regions and the difference thereof under different tasks (Greene et al, 2001;Greene et al, 2008). Patent document CN 104207778A discloses a mental health detection method based on resting state functional magnetic resonance imaging technology, which analyzes brain resting state data by using functional magnetic resonance imaging technology and support vector machine method according to the characteristic that mental health bad condition can be expressed as brain functional network activity abnormality, thereby achieving the purpose of assessing mental health condition of personnel under the condition of lacking priori knowledge. Chunner et al (2009) believe that despite the spatial positioning advantage of fMRI, it is difficult to provide accurate evidence over time for detection due to its lack of temporal precision.

Preferred embodiments:

news materials of the Chinese athlete's sports moral behavior reported by authoritative portal sites such as the search for fox sports in 2000-2017 are selected as main materials of qualitative study, and network materials are searched and collected according to Olympic games and partial common non-Olympic games and by combining with subject matters such as violence, malicious foul, stimulant, passive match, moral behavior and the like. Finally, 598 news stories are collected after the same articles and irrelevant materials of repeated stories of the same event or reloaded from different websites are removed.

In addition to searching and collecting network-related news stories, studies have interviewed 90 active high-level athletes about athletic performance loss. Of these, male 41 (45.56%), female 49 (54.44%); 27 (30%) of the games participating in provincial level, 63 (70%) of the games of national level; average age 20.72 (standard deviation sd=1.92) years old; training years 8.12 (sd=1.90); sports are related to basketball, football, track and field, taekwondo, judo, free play, tennis, table tennis, volleyball, badminton, etc. In face-to-face interview format, interview questions surround "do you have or see moral misbehavior in contests? Can talk about the situation at the time? (time, place and reason) "develop, interview time is scheduled at night after the athlete's training session ends, interview place is selected at the coach or teacher office, formal interview time lasts approximately 40 minutes. In addition, to reduce the socially desirable effects of athlete interviews, research has controlled socially desirable effects in terms of program control, such as emphasizing anonymity and confidentiality of the interview prior to formal interviews on the athlete; emphasis is placed on the importance of athlete self-reporting authenticity and accuracy to interview results, and so forth.

The collected 598 news stories and interview recordings of 90 athletes were collated and transcribed to Word text using the nvivo8.0 management and analysis data from australian QSR, and the text was imported into the nvivo8.0 software for reading. Meanwhile, according to the root-taking theory principle, a three-stage coding mode (open coding, main shaft coding and selective coding) is adopted to analyze and process the data.

In the process of reading and thinking data, sentences related to the sportsman's moral misbehavior are first found out and corresponding open codes are carried out. After open coding, 26 valid free nodes are initially formed. Next, after comparing, analyzing and adjusting the 26 free nodes formed in the open code, 6 spindle codes were generated as shown in table 1.

Table 1 spindle code information

By spindle encoding, it was found that 6 spindle encodings can be generalized into four core categories, as shown in FIG. 2. Wherein, the physical violence, language violence and cold violence mainly reflect the violence behaviors of athletes in competition and are called violence behavior classes; the stimulant use class reflects the athlete's stimulant use behavior; false and negative games, mainly reflecting the false and negative games of athletes in competition; the self-learning dishonest behavior class reflects dishonest behaviors which are only self-known by athletes and occur in competition and cannot be detected or found by referees and the like. Self-learning dishonest categories are a relatively specific type of behavior, mainly arising from athlete interviews, and are less discovered in collected news stories. Unlike the other three categories, the occurrence of self-learning dishonest-like behavior is known only to the athlete himself and is not found by referees or officials, etc. -i.e. the behavior does not cause "adverse consequences" to the individual. Finally, the types of behaviors of athletes with moral loss are classified into four core categories of violence, stimulant use, false ball and passive match and self-learning dishonest by open coding, selective coding and principal axis coding.

The experimental materials were derived from typical examples in previous property studies. According to the behavior types of the exercise moral, the typical examples are read, considered and analyzed by the research, and common and widely-influenced examples are selected from the typical examples to be written (160 in total and 40 in each class). When written, the following principles are followed: 1) Emphasizing the 'moral conflict' of written materials; 2) Emphasis on the word "popular and easy to understand"; 3) Ensuring that sentence patterns and structures of different types of experimental materials are consistent after writing; 4) Ensuring that the athlete can understand the experimental materials of all sports.

In terms of evaluation of the effectiveness of the experimental materials, the study assessed the effectiveness of the experimental materials in terms of percentage approval, decision time, ethical conflict, ethical acceptability of behavior, emotional pleasure, and emotional arousal, and performed both the test analysis and the project analysis (mcguile, langdon, colthesis, mackenzie, 2009). In terms of approval percentages, studies found that no material response ratio of 100% or 0% occurred, indicating that the four classes of experimental materials developed had good distinctions. Meanwhile, the percentage of the player's merit of the excitatory use class and the violence behavior class is lower than that of the false race, the negative race class and the self-learning dishonest class, and the selection rate of the merit of the self-learning dishonest class is highest. This is probably because the use of stimulants, on the one hand, is against olympic spirit and, on the other hand, can be detrimental to the physical health of the athlete, together with the development of propaganda educational works such as the state's counter-excitement, etc., leading to the above-mentioned results. The point of view is also described from the side, as the point of view that the evaluation score of the ethical acceptability of the stimulant using the class behavior is the lowest. The selection of the performance class is relatively low, possibly because individuals in the performance class scenario are more likely to adhere to ethical principles and less likely to make performance selections in the performance scenario. The percentage of the successful agreement between the false game and the negative game is high, probably because the decision of the successful outcome of the athlete in the scene is based on strategic thinking, such as winning the game or getting better game name, etc., and the successful choice is often made. The selected rate of the merit of the self-known dishonest class is highest, which is caused by the characteristics of the self-known dishonest class. In such situations, the athlete's behavior is often known only to the athlete himself, neither "will" nor "will be perceived by the referee or official and will not have serious consequences, and thus the individual is prone to make a positive selection when in a self-aware judgment scenario.

In terms of decision time, studies have found that athletes spend different decision times in facing different sports moral judgment scenarios. Wherein, the decision time of the stimulant use class is the shortest, the violence behavior class is the second most, the false race and the negative race and the self-learning dishonest class are the longest. As previously described, stimulant use is against olympic spirit and in addition jeopardizes the physical health of the athlete, so that less of a positive choice is made when the athlete is faced with a stimulant use scenario, the response time is relatively short, and for false and negative matches and self-learning dishonest, the athlete may need to repeatedly trade off advantages and disadvantages, and therefore, the response time spent is relatively long. In the aspect of ethical conflict evaluation, four types of experimental materials are found to have significant differences through research. Meanwhile, the evaluation scores of the ethical conflict of the four types of experimental materials are higher, and experimental materials which do not have ethical conflict are not generated, which also shows that the developed experimental materials have good ethical conflict. In addition, the class of stimulant use has the highest evaluation of ethical conflict compared to other types of experimental materials, which may be due to the fact that the class of stimulant use is against the spirit of sports ethical or olympic, which in addition is harmful to the physical health of athletes, and the class of stimulant use has the lowest performance acceptability from the perspective of the performance's evaluation of ethical acceptability.

In terms of the ethical acceptability of behaviors, research finds that the four types of experimental materials have significant differences, and meanwhile, the ethical acceptability evaluation scores of the four types of experimental materials are low, because the ethical behaviors related in the four types of experimental materials belong to the exercise ethical loss behaviors. In addition, studies have found that the class of stimulant use has the lowest evaluation score for ethical acceptability, indicating that athletes exhibit general disapproval of stimulant use behavior. In terms of emotional pleasure and emotional arousal, studies found that there were significant differences in emotional pleasure and emotional arousal (except for the test analysis of emotional arousal) for the four classes of materials, indicating that all four classes of experimental materials caused the aversion and tension of the test, and that this emotional state was related to the dilemma of "will" and "will not" of the test selection. This is because the four types of experimental materials all have ethical conflict, if the judicious judgment is against ethical or olympic spirit, the competition is lost or the influence is taken, and thus the tested selection of "will" and "will not" will all face negative results. Furthermore, while all four classes of experimental materials induced aversion and tension, none of the Lotto, manfrinati and Sarlo (2014) et al found that strong. This is because the two-difficulty situations of sports constructed by four kinds of experimental materials are all examples of frequent occurrence in competitive sports, and the life area ethical dilemma compiled by Lotto et al mostly involves extremely life-death choices in philosophy, thus leading to the occurrence of the above results.

In addition, from the analysis of variance of the sports (the sports related to the test and the sports related to the experimental materials for moral judgment) and the dependent variables, the effects of the sports related to the test and the sports related to the experimental materials on the approval percentage, the decision time, the moral conflict, the moral acceptability of behaviors, the emotional pleasure and the emotional arousal degree are not obvious, which means that the four types of experimental materials developed are not influenced by the sports. Therefore, whether the test analysis or the project analysis is carried out, the developed four types of experimental materials are easy to understand and answer for all project athletes, and can be used as effective experimental materials for developing motor moral judgment cognitive neurological research.

Prior to developing a formal ERP experiment, studies evaluated the effectiveness of four classes of experimental materials. The study co-recruited 187 athletes in different fields (excluding ERP trials) and rated the effectiveness of the experimental materials from six aspects of approval percentages (equity selection), decision time, ethical conflict, ethical acceptability of behaviors, emotional pleasure, and emotional arousal, according to the related studies in the past (Lotto et al, 2014) and advice (mcguile et al, 2009), as well as the trial analysis and project analysis. The results of the effectiveness evaluation show that (table 2 and table 3) the four experimental materials have significant differences in the six aspects, and the results of the tested analysis and the project analysis are consistent and are not affected by the sports project. Therefore, the material can be used as an effective experimental material for developing athlete motor moral judgment cognitive neural mechanism research.

Note that: the sports items related to the sports judging material include 32 kinds, and the plurality of track and field items are all classified into track and field items during analysis.

According to the purpose of the invention, the study adopts a completely tested internal experimental design, namely, each tested person needs to complete the response of four types of experimental materials, so as to avoid the influence of the individual difference of the tested person on the experimental result. The independent variables are the judgment type of the moral out-of-range behavior of the exercise, and the dependent variables are the approval percentage, the decision time, the peak amplitude (or average amplitude) of each component of the ERP and the latency. According to the purposes of the present invention and the relevant research paradigm (Li Jian et al, 2011;Manfrinati et al, 2013; sarlo et al, 2012; wang et al, 2014), each exercise morally judged experimental material is presented in a double screen, i.e. the first screen presents a basic background, the subject can read according to its own reading speed, after reading is completed, enter the next screen by pressing the "space key", the next screen will present a decision and a question with conflicts "do you do so? The tested person needs to make a judgment of 'meeting' and 'not meeting' on the problem within 8 seconds, and the electroencephalogram record starts from the condition that the second screen presents the choice action until the athlete finishes answering the problem. Analysis of variance shows that the four classes of experimental materials presented on the second screen do not differ significantly in word count, F (3,156) =1.29, p > 0.05. To balance the left and right hands, one part of the test is "will" the keyboard letter "Z", "will not" the keyboard letter "M", and the other part of the test is "will" the keyboard letter "M", "will not" the keyboard letter "Z". After the answer is completed, the computer automatically presents the next material, as shown in FIG. 3. The experiment contained 4 blocks, each consisting of 40 kinematic ethical dilemma questions (10 per class). Meanwhile, in order to reduce the social expected effect of athlete answering, besides the confidentiality, anonymity and the importance of answering authenticity and accuracy of the research result are emphasized before the formal experiment starts, four types of experimental materials contained in each Block are randomly presented, and the answers of self-learning dishonest type are reversely operated (selecting "meeting" represents non-merit judgment and "not" represents merit judgment). After each Block is completed, the computer automatically presents a rest language prompt, the tested person can rest according to the fatigue degree of the tested person, and the experiment lasts for about 40-50 minutes.

Behavioural data was collected by E-prime 2.0. ERP data was collected using an electroencephalogram collection system (64 conductivity electrode cap) manufactured by BP company, germany, and EEG data was processed offline using Analyzer 2.1. The study selects the average potential of mastoid on two sides as a reference electrode, adopts a semi-automatic mode to remove the eye electricity and other artifacts, 50HZ mains supply interference and eliminates artifact signals with the amplitude larger than +/-80 mu V. According to the object of the invention and related studies (Sarlo et al 2012), the study selected 27 electrode points (FP _Z 、F _Z 、F ₁ 、F ₂ 、F ₃ 、F ₄ 、FC _Z 、FC ₁ 、FC ₂ 、FC ₃ 、FC ₄ 、C _Z 、C ₁ 、C ₂ 、C ₃ 、C ₄ 、CP _Z 、CP ₁ 、CP ₂ 、CP ₃ 、CP ₄ 、P _Z 、P ₁ 、P ₂ 、P ₃ 、P ₄ 、O _Z ) Processing and analysis were performed. The analysis time course was chosen at 200ms before stimulus presentation-800 ms after stimulus was the stimulus lock, and baseline correction was the mean of 200ms before stimulus presentation. The analysis time course of the reaction lock time is selected from 1000ms before reaction to 500ms after reaction, and the baseline correction is the average value of-1000 ms-800 ms before reaction. The average superposition times of the four types during the stimulation of the lock are respectively as follows: 27.90+/-5.16 times of violence, 27.16+/-6.14 times of stimulant use, 26.04+/-6.98 times of self-learning dishonest, and 27.53+/-6.55 times of false match and negative match; the average superposition times of the four types during the reaction lock are respectively as follows: the violence behavior class is 28.83+/-6.78 times, the stimulant use class is 30.94+/-8.08 times, the self-learning dishonest class is 30.78 +/-7.48 times, and the false race and the negative race class are 28.28+/-8.38 times. Furthermore, it is obvious that And (3) researching and selecting the maximum peak value in the corresponding time interval to carry out statistics and analysis on the amplitude of the peak amplitude, and selecting the average amplitude in the corresponding time interval to carry out statistics and analysis on the component of which the obvious peak amplitude cannot be identified. Repeated measurement analysis of variance is carried out on the data by adopting SPSS16.0, and correction is carried out by adopting a Greenhouse-Gessiser method when the non-sphericity of the result is counted.

The study results of the behavior results show that:

in terms of decision time, the violence behavior class 2084.94 ± 518.78ms, the stimulant use class 1756.64 ± 641.43ms, the self-learning dishonest class 2849.33 ± 604.75ms, the false race and the negative race class 3156.47 ± 738.64ms. Obviously, the decision time of the false and negative games is significantly higher than that of the violent behavior, the stimulant use and the self-learning dishonest, wherein the decision time of the stimulant use is the shortest. Analysis of variance showed significant differences in decision time for the four classes, F (3, 54) =31.12, and p < 0.01,Pairwise Comparisons analysis showed significant levels for both of the four classes. In terms of percentage of dyscrasia selection, violence categories 23.03±17.09%, stimulants 11.97± 27.24%, self-learning dishonest categories 82.50±23.33%, false racing and passive racing categories 33.82 ±25.2%. The approval percentage of self-known dishonest class is much higher than that of violent behavior class, stimulant use class, false race and negative race class, and the approval percentage of stimulant use class is the lowest. Analysis of variance shows that four classes have significant differences in terms of approval percentages, F (3, 54) =55.82, and p < 0.01,Pairwise Comparisons analysis shows that the violent behavior class has significant differences from the other three classes, the stimulant use class has significant differences from the self-learning dishonest class, and the stimulant use class is not significant in comparison with the false match class and the negative match class.

ERP result display:

to better understand the cognitive processes and mechanisms of four classes of motor moral judgment, studies analyzed and processed EEG offline data from both stimulus and motion lock time.

The research finds that the four classes of judgment have obvious difference in decision time, the decision time of the class of using the stimulant is shortest, the false match and the negative match and the self-learning dishonest class are relatively long, so that the athlete can quickly make a selection when facing the scene of judging the class of using the stimulant, and can take a long time to make a selection when facing the class of using the stimulant. This may be because the stimulant is more sensitive to use and in addition, may harm the physical health of the athlete, the athlete may make less of a positive choice and thus the time to answer is the fastest, and for false and negative games and self-learning dishonest, the athlete may need to repeatedly weigh the advantages and disadvantages and the time to answer is relatively long. In terms of the percentage of the dyscrasia, research finds that four classes of judgment have significant differences, and the percentage of the dyscrasia selection of the self-known dishonest class is far higher than that of the violence behavior class, the excitant use class, the false race and the negative race class, which are caused by the characteristics of the self-known dishonest class. In such judgment scenarios, dishonest behavior of the athlete is often known only to the athlete himself, neither "can" nor "can be perceived by referees or officials without serious consequences, and thus individuals tend to make a positive choice when in a self-known ethical judgment scenario. At the same time, studies have also found that the percentage of positive selection of the class of agonist use is minimal compared to the other three classes of judgment. As previously mentioned, the use of stimulants is more sensitive, and in addition, the use of stimulants can be detrimental to the athlete's own health, leading to the above-mentioned consequences.

The ERP average waveform when the lock is stimulated shows that four judging tasks induce obvious visual ERP early components, namely P1 and N1, in the cerebral cortex. Both P1 and N1 are exogenous ERP components, the main components of attention effects, representing early processing and handling of stimulus information recognition or perception by individuals. The P1 component is generally considered to be involved in the choice of attention, the amplitude reflecting how much the individual is paying attention to the stimulation information and the latency reflecting the speed at which the individual pays attention to the stimulation information (Mangun et al, 1991); the N1 component is related to cognitive recognition of attention, the amplitude reflects the level of attention, recognition or discrimination of the individual to the stimulus information, and the latency reflects the speed of recognition of the stimulus information by the individual (Vogel et al, 2000). The invention finds that the main effects of the P1 and N1 components induced by the four judging tasks are not obvious, which indicates that the four judging tasks are not different in early perception and recognition processing of the stimulation information. Meanwhile, studies have also found that four classes of judgment induce significant late-stage component P260, P260 is generally regarded as an integrated component of P2 and P3 components (Wang et al, 2014), a typical component of ethical judgment task induction, reflecting the immediate emotional response of individuals after ethical dilemma processing (Sarlo et al, 2012). As in Sarlo et al (2012) studies, it was found that tool ethics induced a larger P260 amplitude in frontal poles and areas than collateral ethics, and that the negative emotion experience tested was significantly positively correlated with the P260 amplitude. However, although the present invention found that all four classes of decisions induced significant P260 component, none of the major effects of amplitude and latency were significant, indicating that there was no significant difference in immediate emotional response resulting from the four classes of decisions. Meanwhile, the LORETA traceable analysis of the P260 component showed that all four classes of decisions significantly activated the right BA10 region, which is a key brain region integrating emotion and cognition (Greene, 2007;Greene et al, 2007;Greene et al, 2004;Greene et al, 2001; wang Yunjiang, guo Benyu, 2017), which illustrates that emotion and cognition both participate in the processing of the four classes of decisions. Furthermore, the study found that all four classes of judgment induced significant late slow negative N500 components. Research into life domain ethics has found that tool ethics induce a higher negative amplitude in the range of 450 ms-600 ms than incidental ethics, and they believe that this component may be related to attention resource allocation and working memory on the one hand, and to cognitive effort required for the ethics process (e.g., trade-offs, etc.) (Sarlo et al 2012). The late slow negative N500 component found by the invention is the same ERP component as the 450 ms-600 ms component found by Sarlo et al, reflecting the individual's cognitive effort in moral judgment. However, the main effects of the N500 component amplitude and latency were not significant, which suggests that there were no significant differences in the cognitive effort required to test in the four classes of judgment.

Besides examining the stimulated lock, the invention also examines the four kinds of judged response locks. The ERP average waveform at the time of response lock shows that four classes of judgment tasks induce a preparation potential BSP, an action potential MP and a post-exercise potential RAF (early component and late component). BSP (also called movement preparation potential) is a slow negative potential change of about 800ms before starting an action, and is a purely psychological brain wave, which is caused by the mind that governs movement. The absence of a BSP component during passive exercise (unnoticed) suggests that the BSP component represents a deliberate exercise (Condition), and studies have also shown that the BSP component reflects the pre-exercise brain preparation processes, such as planning and preparation of exercise. The invention finds that the BSP component average amplitude main effect induced by the four types of motion morality judging tasks is not obvious, which indicates that the four types of motion morality judging are not different in the processing of the motion preparation stage. Action potential MP is a negative component of about 100ms after exercise, reflecting early execution of exercise. The invention finds that the main effect of MP components induced by the four types of judging tasks is not obvious, and shows that the four types of judging have no difference in early processing of action execution. Post-exercise potential RAF (early and late) is a positive ERP component generated within 50 ms-350 ms after exercise, reflecting the post-exercise execution process. The invention discovers that the RAF component main effect induced by the four classes of judgment tasks is not obvious, which indicates that the four classes of judgment have no obvious difference in the processing of the later stage of action execution.

In summary, each ERP component analysis at the time of stimulus locking and at the time of response locking shows that the four classes of judgment have no significant difference in cognitive neural mechanism processing. Because all four classes of judgments fall within the category of ethical judgments and not non-ethical judgments (e.g., fact judgments, etc.), from the standpoint of "ethical brains" (i.e., brain regions related to ethical event information processing are all identical) (Abend, 2011), the brains all initiate the human "ethical brains" when ethical judgments are processed, and the results of the traceable analysis of ethical judgments representative component P260 also indicate that all four classes of judgments significantly activate the right BA10 region, which is generally considered to be a critical brain region integrating emotion and cognition (Greene et al 2002;Lerner et al.,2015; wang Yunjiang, guo Benyu, 2017; zhu Chunyan, wang Kai, 2005;Pascual et al, 2013), which illustrates that cognition and emotion are both involved in the processing of all four classes of judgments. Therefore, the cognitive neural mechanisms of four types of motor moral judgment are not different, and are the result of combined action of cognition and emotion.

From the above analysis:

when judging the violent behavior class, the stimulant use class, the false match and the negative match class and the self-learning dishonest class, the athlete has the shortest decision time of the stimulant use class and the longest decision time of the false match and the negative match class; self-learning dishonest classes are more prone to make a positive selection and violent behavioral classes are more prone to make a non-positive selection.

The violence behavior, the stimulant use, the false race and the negative race and the self-learning dishonest are not significantly different in all ERP components induced by stimulating and reacting to lock, and the traceable analysis of the P260 component shows that the right BA10 area is significantly activated, so that the four types of motor morals judge that the four types of motor morals have the same cognitive nervous mechanism and are the result of the combined action of cognition and emotion.

Therefore, the invention can judge the ethical trend by the analysis conclusion reflecting the objective rule of the brain wave.
