Research On Attentional Bias Of Different Roles In Simulated Theft

As for attention bias,most of the domestic and foreign studies focus on people with anxiety,depression,different mental health,mental states,and different personality traits.They mainly focus on the components or influence mechanisms of attention bias.Research on attention bias components can be divided into two categories: static attention bias and dynamic attention bias.Static attention bias is mainly based on the response time of the research point detection paradigm and cue target paradigm.Researchers believe that static attention bias mode conforms to the theory of attention alertness or avoidance hypothesis;while dynamic attention bias mostly focuses on eye movement research,and attention bias mode conforms to Be alert to avoid the hypothesis.In this study,two experiments were used to explore the characteristics of attention bias of different characters in the simulated theft situation.The first experiment started from the simulated theft situation,used the point detection paradigm combined with Concealed Information Test,and produced target pictures and supporting pictures related to the case.College students are the research objects(including 35 in the crime group,34 in the insider group,and 30 in the innocent group),discussing the static attention bias characteristics of subjects with different roles,and whether different roles will have attention bias for the target pictures related to the case.Experiment 2used eye trackers to study 106 college students(36 in the crime group;33 in the informed group;37 in the innocent group),and further explored the attention of the perpetrators,insiders and innocent people to the target pictures Bias differences and dynamic attention bias characteristics.Finally reached the following conclusions:(1)the point detection task paradigm was used to investigate the characteristics of the attentional bias of different roles.The results of experiment 1 showed that the perpetrator would give priority to the information related to the case,develop attentional bias to the target pictures related to the case and show a single attentional vigilance.The insider and the innocent didn't pay attention to the target picture.Attentional bias scores indicate that the perpetrator and insider can be effectively distinguished from the perpetrator and the innocent.(2)Using the eye tracker combined with the free browsing paradigm,a dynamic study of the attention bias of the perpetrators,insiders and innocents was carried out.The experimental results show that the perpetrator has a dynamic attention bias component on the target picture: attention alertness-attention disengage Difficult;the insider showed only a single attention to maintain the target picture;innocent people have no change characteristics.The total fixation time and fixation times in the interest area can effectively distinguish the perpetrators,insiders and innocents.(3)Through experiment 1 and experiment 2,it is found that the perpetrators will have attention bias toward the target pictures related to the case,but the attention mode is not a single but a dynamic process,which is shown as attention alertness-attention out of difficulty;The target picture has attention to maintain,while the innocent has no attention bias to the target picture.
