The Eye Movement Study Of Attentional Bias Training Towards The Subjects With Cognitive Vulnerability To Depression

There are many factors that can cause the depression,cognitive factor is one of the important aspects.The depression people often have too much attention to negative emotional information.The subjects with cognitive vulnerability to depression also can produce the same attentional bias as the depression patients.Researchers generally will regard attentional bias as one of the cause of psychological problems.The researchers found a attentional training that can change individual's attentional bias.In the subsequent research this attentional bias training also shows that for some psychological problems have good relief effect.There are two experiments for this study.This study sought to assess whether attentional bias training(ABT)have a positive effect on the subjects with cognitive vulnerability to depression.Furthermore,to investigate in which present time the ABT have a better effect.And according to the Cognitive Style Questionnaire(CSQ),we filter out the subjects with cognitive vulnerability to depression.The form of the ABT is dot-probe task.The data of the two experiments recorded by the eye tracker.The second experiment is based on the first experiment.And we also add a new variable presentative time(500ms,1250ms).The procedure of the experiments is according to Wadlinger and Isaacowitz's: participants first completed pressure task which includes pictures of high negative emotion.Then,they were administered the ABT task followed by a second assessment of state anxiety and frustration.This first administration of the pressure task ensured participants were under stress before taking the dot-probe task.The result of the first experiments showed that the ABT has good efficacy to the subjects which is a healthy control group and a cognitive vulnerability,but to the depression group the effect is not significant.The result of the second experiments turns out that in the presentative time of 1250 ms,the depression group'effect is significant and all the three group have a better effect.This also illustrates to the depression class,the ABT mostly will play a good effect during the later stage of attention.The conclusions of this study are as follows:(1)Under the condition of 500 ms present time,the positive ABT could has a good effect on the subjects with cognitive vulnerability to depression.(2)The ABT influenced by time factors,it has a better effect on the subjects with cognitive vulnerability to depression when the present time is 1250 ms.(3)The time effect which the positive ABT shows indicates that to the depressed subjects ABT will play a good effect during the later stage of attention.
