A eye-tracking study on the characteristics of attentional bias toward the emotional information and relation to the rumination in depression adolescents
Objective To analyze oculomotor behavioural characteristics of attentional bias towards emotional information in adolescents with depressive disorders and its correlation with rumination.Methods The study measured attentional bias in 35 adolescents with depressive disorders and 45 normal college students using the eye movement test,and assessed rumination using the ruminative thinking questionnaire.Results Statistically significant differences were found between adolescents with depressive disorders and normal college students in attentional bias latencies,stimulus category effects,and cross-effects scores(F=8.31,9.39,13.64,all P<0.05).Simple effects analyses revealed a significant difference between the two groups in gaze latency for positive pictures(F=15.45;P<0.001).The statistical analysis did not reveal any significant differences between the between-group main effects,stimulus category main effects,and between-group and stimulus category cross-over effects on difference scores when attending to biased first fixation and between-group main effects,stimulus category effects,and between-group and stimulus category cross-over effects on difference scores when attending to biased total gaze(P>0.05).A significant negative correlation was found between positive first fixation scores and enjoyment of pleasure scores and positive coping(r =-0.392,-0.166,all P<0.05).Additionally,a significant positive correlation was found between negative first fixation scores and enjoyment of pleasure scores(r=0.289,P<0.05).The duration of positive first fixation scores showed a positive correlation with pleasure and positive coping(r= 0.309,0.268,both P<0.05),while negative first fixation duration scores were positively correlated with negative attributions(r= 0.194,P<0.05).Conclusions Adolescents with depression lack initial attention towards positive emotional information.Rumination is associated with accelerated and prolonged attention towards emotional information in adolescents with depression.
