The purpose of this study is to compare the attention bias of negative stimuli between people who have psychological problems and people who do not. During the study, people completed self-reporting questionnaire – the same questionnaire used for those participating in “HARU”- to check the severity of and what type of psychological problems they had. After the survey, they completed a pictorial dot-probe task of several types and word IAT(Implicit Association Task) tasks. Each task was composed of positive, negative, or neutral conditions. Thus, the current study aims to examine the effects of psychological problems (depression, anxiety, sleep, pain) at the cognitive level and to check the effects of emotion on cognition.
