An Study On The Characters Of Social Information Coding Among High School Students Of Impulsivity

High school student is an important part of adolescent. Their physical and mental development is in an imbalanced, instable and immature stage, combined with a variety problems of academic, interpersonal, economic pressure and self growth, which makes them vulnerable to a variety of psychological and behavioral problems, such as impulsive buying, aggression even impulsive to commit self-injury and suicide behavior. Impulsivity performs as individuals lacking management and control on self-cognition, plans, and behavioral occur quick and unplanned reaction without consciously balancing the consequence. As a kind of personality traits, the research field and content of impulsivity is extensive. With the rise and development of cognitive psychology, the research to the internal process and mechanism of psychological activities has become a trend. Through extensive review of related literature we have the knowledge that, the current research on general group impulsivity mainly concentrated in the group of college students, community groups, and a few pupils, there is few research on senior high school students, and the impulsivity research from the perspective of cognitive processing is few. Therefore, understanding the development of impulsive characteristic in adolescent group and exploring the impulsive style inner mechanism of individual information processing coding phase are the aims of this study.This research mainly contains two parts. Firstly, BIS-11(Barratt Impulsivity scale11th version) as tool,4188high school students in Chongqing as objects, with two-year follow-up investigation, the study investigated the development of the adolescent impulsive characteristic, and the differences on gender, source, etc. Secondly, according to the questionnaire scores to select the subjects, adopting three behavior experiments, the study used the exploration of impulsive individual attention bias characteristics and memory bias characteristics to examine social information coding characteristics of them. The final conclusions are as follows:(1) The impulsive characteristics of adolescent changes obviously over time, and the difference is significant difference in gender, origin, etc;(2) In the attention characteristics experiment, the different categories of subjects have different reaction time when the probe stimulus appears on the different part of speech of the word, the HG(the high score group of BIS) responses significantly lower than LG(the low score group of BIS) on the reaction of probe stimulus; the HG responses on the probe stimulus of negative words significantly lower than on the probe stimulus of positive words; When depression as a covariate, subjects showed no influence on attention bias.(3) In the experiments of sensory memory characteristic, on subjects, the memory amount of positive and neutral words is significantly greater than the one of negative words. When depression is regarded as a covariate, subjects appeared no obvious difference on the memory amount of three kinds of parts of speech words. Depression in sensory memory level has distinct effect on the memory of different parts of speech.(4) In the experiments of memory of the semantic level of processing characteristics experiments, subjects showed remarkable differences in the recall of different part of speech on subjects of HG, the amount of negative words is significantly higher than that of the positive and neutral vocabulary, the HG on the recall of negative words were significantly higher than that of LG. When depression factor as a covariate, subjects have no significant difference in the recall of different part of speech, depression has a great influence on the recall of different wordsat the level of semantic memory.
