| From cooperative behavior in RNA replication engineering to potential cooperation between humans and intelligent organisms from abroad,explaining the possibility that these cooperative behaviors are ubiquitous in nature is one of the most challenging scientific research issues in the past 150 years.Based on the prisoner's dilemma game experiment,this paper will study the influence of gender onymity on the choice of game strategies,which is a rich research on the evolution of cooperative behavior.We recruited volunteers from Yunnan University of Finance and Economics and Yunnan University.Using z-Tree software,we designed the corresponding repeated prisoner dilemma game experiment: control group experiment T1 and control group experiment T2.In T1,each player interacts with his opponent completely anonymously,while in T2,each player will show his opponent's gender on the experimental interface of each round.Whether it is control group experiment T1 or control group experiment T2,each experiment should be conducted in multiple rounds.In each round,the game player will play two-two games with the same opponent randomly allocated by the system,and make 1-9 rounds randomly.At the end of each round,the probability of the two sides continuing the next round is 75%.If the next round is not continued,the experiment will be finished,then the next round will be entered,and the opponent will be replaced.The experiment will be completed for at least 80 rounds.In addition,no matter in the experimental group experiment T1 or in the control group experiment T2,each experimental player can see the following relevant information about each interaction of the game with his opponent in the experimental interface during the experiment process: number,strategy adopted in each round(c or d).The total benefits of his experiments are updated in real time and can be seen by himself.The experiment was carried out through a computer local area network,and each experimental gamer used a computer independently.In order to ensure the validity of the experiment,we divide the experiment into three parts: The first is the explanation of the experiment instructions,which ensures that each experimental gamer understands the experiment and knows the experimental steps by means of random questioning;The second is a test experiment.We will ensure that all the experimental players know how the experiment was conducted,the experimental steps and the game operation through this interaction of experiments.The third is to carry out formal experiments,during which the income of each round of experiments will be included in the final total income of the player.At the same time,the number of interactions of experiments and the number of rounds of each round of experiments will also be included in the total number of rounds and the total number of rounds of formal experiments.The data analyzed in this paper included 9 experiments,of which two experiments that do not show gender and seven experiments that show gender.There were 328 experimental gamers,159 male experimental gamers and 169 female experimental gamers.The average age of experimental gamers was 19.63 years old.There were 60 experimental gamers in the experimental group that do not show gender and 268 in the experimental group that show gender.In the third chapter of the article,we used five subsections to describe,analyze and compare the experimental data of the two groups of experiments.In the fourth chapter of the article,we use the generalized linear model and the generalized linear mixed model to model and analyze the experimental data.The study found that in the experimental group that do not show gender,male gamers were more inclined to cooperate than female gamers.The cooperation rate of male-male group was higher than female-female group.The cooperation rate of male gamers was higher than female gamers in mixed gender groups.In the experimental group that show gender,female gamers were more inclined to cooperate than male gambers,and the cooperation rate of female-female group was higher than male-male group.The hypothesis that there is no gap between male and female and the rate of cooperation can not be rejected in the mixed gender group.The study also found that compared with experiment that do not show gender,the average total cooperation rate of experiment that show gender was significantly higher than that of experiment that do not show gender;the cooperation rate of the gamers of experiment that show gender was significantly higher than that of the gamers of experiment that do not show gender;the cooperation rate of female gamers in experiment that show gender was significantly higher than that of the female gamers of experiment that do not show gender;there was no significant difference in the cooperation rate of the participants,and the cooperation rate of the male gamers in the experiment that show gender was only slightly higher than that of the male gamers in the experiment that do not show gender by two percentage points;the cooperation rate of the female-female group in the experiment that show gender was significantly higher than that of the female-female group in the experiment that do not show gender;the cooperation rate of the male-male group in the experiment that show gender was significantly lower than that of the male-male group in the experiment that do not show gender;the cooperation rate of mixed gender group in experiment that show gender is significantly higher than that of mixed gender group in experiment that do not show gender;the cooperation rate of male gamers of mixed sex group in experiment that show gender is obviously higher than that of male gamblers of mixed gender group in experiment that do not show gender;the cooperation rate of female gamers of mixed gender group in experiment that show gender is obviously higher than that of female gamers of mixed gender group in experiment that do not show gender;In addition,we also found that the average earnings of male and female experimental gamers were significantly positively correlated with the number of cooperative strategies used in the experiment that show gender,while in the experiment that do not show gender,there was no significant correlation between the average earnings of male and female experimental gamers and the number of strategies used.Based on the above findings,we believe that showing the gender of game rival on the experimental interface can effectively promote the overall cooperation rate,especially the female cooperation rate.The reason for this phenomenon is that each person in social interaction,when exposed to more personal information of the social interaction object,pays more attention to their own actions in society.Especially women's consideration,is more complex and diverse,so they prefer friendly cooperative communication to show their own.
