The Character Of Social Information Coding Among High School Students Who Are Struggling With Suicide Ideation

Committing suicide serves as the leading cause of death among adolescents in china. Suicidal ideation is the early psychological activity of suicide attempters and suicides. Clinical study proves that 80 percent suicides show various forms of suicidal ideation. Therefore, analyzing the adolescents'suicidal ideation and actively intervening their behaviors becomes one of the major measures to prevent committing suicide.Psychologists have researched the detection rate of the adolescents'suicidal ideation, influence factors and interventions from the aspects of psychology, physiology, society and so on, thus deepening people's understanding to suicidal ideation of teenagers, which provides adolescents with some theoretical explanation and guidance to prevent and intervene committing suicide. However, at present, researches in the field are mainly about the origin of teenagers'suicidal ideation and interventions on account of the complexity of teenagers'suicidal ideation. There are few systemic researches on mental mechanism of adolescents'suicidal ideation from the point of the process of social information machining.The research investigated 3014 senior middle school students by questionnaires and interview and had the experiment to 316 participants. The results are as follows:For the participants from the EG (experimental group), the reaction time of the detection stimulation on passive vocabulary is significantly shorter than that on active vocabulary; whereas for the participants from the CG (control group) the reaction time of the detection stimulation on passive vocabulary is significantly longer than that on active vocabulary.The number of passive words that the participants can recall is significantly more than that of active words and neutral words. As the number of words that the participants can recall, there is not a clear difference between the EG and CG. There is not a notable interaction of part of speech and group. The depression factor has a greater influence on the part of speech. When depression was added as covariates, the effect of part of speech is no longer significant. The number of active words that the EG participants can recall is significantly lower than CG participants; the number of passive words that the EG participants can recall is significantly higher than CG participants; there is no obvious difference about neutral words.
