摘　　要：以高低强迫倾向个体为研究对象,考察其在不同概率情景设置的Flanker任务中的信息加工灵活性,研究结果表明:高强迫倾向个体的信息加工方式相对较缓慢、单一,以集中加工方式为主;高强迫倾向个体对情境的变化较少做出反应,在信息加工的灵活性上存在缺陷,而低倾向个体的信息加工方式相对较灵活;高强迫倾向个体不易受线索提示的影响,对信息加工方式的策略性调控能力不足。Obsessive-compulsive disorder （0CD） is a common clinical psychological disease. A large number of studies have shown that 0CD patients have cognitive dysfunctions especially in attention, decision making, and information processing and so on. Previous studies of information processing in OCD focus on processing ways, but pay not so much attention to the flexibility of information processing which is a component of executive function. Moreover, OCD patients have deficiency in executive functions. So we propose that information processing flexibility indirectly reflects the insufficiency of OCD patients in executive functions. And it is necessary to explore the characteristics of OCD in the information processing flexibility. In order to eliminate the effects of other comorbid factors, we use Padua Inventory to screen high obsessive-compulsive tendency （HOC） and low obsessive-compulsive tendency （LOC） individuals as the research objects from the university students. The final sample includes 11 HOC and 10 LOC participants. By adjusting the individual probability （i.e., before each trial to give clues to prompt probability）, the study set the scene of different probabilities used in the Flanker task （consistent stimulus （HHHHH ／ SSSSS） and inconsistent stimulus （HHSHH ／ SSHSS））, to examine whether the obsessive-compulsive tendencies will have differential information processing ways because of the changes in different probabilities scenarios and to verify the differences of the information processing flexibility between the two groups. The study designed three clues including ＂＋＂, ＂-＂, ＂？＂ , representing three kinds of signal probability： 80% （80% of the following stimulation would be consistent）, 50% （50% of the following stimulation would be consistent）, and 20% （20% of the following stimulation would be consistent） .The reaction time and parallel processing index by the Flanker task were used as the dependent variables. The results showed that： （
