Attentional Bias In College Students With Different Level Of Aggression

The human beings have studied aggressive behaviors for a very long time. Park once said:"there is few research projects, such as attack and attack behavior, which have evoked so many theories and practice in the past century." The domestic scholars also follow closely the international research trend, emerging one aggressive research after another. With the development research technology, the researchers make a extensive study of aggression from the following two aspects:explicit and implicit level. As theories vary, no unanimous conclusion can be drawn. Studies of attention bias is a hot spot in the field of emotion and cognition in recent years. This research adopted emotional face pictures as experiment material, and two experiment tasks including the probe detection task and cue-target task were used to explored the characteristics and intrinsic mechanism of attention bias on the college students with different aggressive levels. The combination of behavioral experiments and questionnaire survey methods was performed in Experiment1. We used the first-year undergraduate to third-year graduate students as research subjects, and the probe detection paradigm in the attentional bias research paradigm was used to explore the characteristics of attention bias concerning the college students with different aggressive levels (explicit and implicit level) to different kinds of emotional face pictures. The results of Experiment1only indicate whether differences in the attentional bias of individuals with different aggressive levels. But this attentional bias is whether attention vigilance or removing difficulties to negative stimuli, and it’s a question to explore of Experiment2. Experiment2also adopted the combination of behavioral experiments and questionnaire survey methods, and the first-year undergraduate to third-year graduate students were also taken into account for research subjects. We used the cue-target paradigm in the attentional bias research paradigm to explore the intrinsic mechanism of attention bias concerning the college students with different aggressive levels to different kinds of emotional face pictures.This study explored the attentional bias in chinese college students with different aggressive levels. The results indicated that (1) when the probe detection task was used to explored the influence of aggressive levels to the attentional bias, we found that high explicit attackers showed attention bias to negative emotional stimuli. Specifically, it could make them go on more alert to negative stimulation under the condition of limited visual attention resources, and it had the characteristics of facilitation during the process.(2) high implicit attackers showed attention bias to negative emotional stimuli, just as the same as high explicit attackers. And it could also make them go on more alert to negative stimulation under the condition of limited visual attention resources. It had the characteristics of facilitation during the process.(3) when the cue-target task was used to explored the intrinsic mechanism of aggressive levels to the attentional bias, the experimental results showed that the average reaction time of high explicit attackers to target stimulus which negative emotional face was clue was significantly longer than that of positive and neutral emotional face under the condition of invalid clues. And it showed obvious attentional removing difficulties. There were no reaction time differences when three types of emotional face was clue as target stimulus under the condition of valid clues. It could not make them go on alert to negative stimulation.(4) the average reaction time of high implicit attackers to target stimulus which negative emotional face was clue was significantly longer than that of positive and neutral emotional face under the condition of invalid clues. And it also showed obvious attentional removing difficulties. There were no reaction time differences when three types of emotional face was clue as target stimulus under the condition of valid clues. It couldn’t also make them go on alert to negative stimulation.(5) the bias mechanism of attention bias on high explicit attackers was the same as that on high implicit attackers.
