基于CQT原理的行为筛查测验研究:认知负荷与情境因素、人格特质的关系

Study on Behavioral Screening Experiment Based on Comparison Question Test: Relationship among Cognitive Load,Situational Factor and Personality Traits

目的探究行为筛查测验中情境因素对认知负荷的影响,并分析真实测试情境下认知负荷与人格特质的关系,为提高现场测试精确度提供依据。方法试验a为实验室试验(laboratory test),无情境创设,被试为30名本科生,以反应时为认知负荷指标。现场试验(field test,即试验b)以新一期心理健康调查工作为依托,被试为某单位已通过前期录用选拔的886名职员,并以反应时作为认知负荷指标,分析筛查测验认知负荷与人格特质的关系。结果不同测试情境下行为筛查测验的认知负荷存在差异。试验a中不同题目类别的认知负荷并无差异,但在试验b中不同题目类别的认知负荷存在差异。调查题目(V2和V3)的认知负荷较高。焦虑个性倾向的在无关题目(V1)和调查题目(V2)上反应时长较长,而个性严谨的被试认真严谨,对待测试认真,卷入程度较高,在调查题目(V2和V3)的反应时长较长。同时自我欺骗因子得分较高的被试,行为筛查测验认知负荷较低。结论情境因素影响行为筛查测验的认知负荷,人格特质与认知负荷有关。

Objective To probe the effect of situational factors on the cognitive load during behavior screening test,and analyze the correlation of cognitive load with personality traits,thus provide more basis for improving the accuracy of field tests. Methods Thirty undergraduates were recruited to participate in a laboratory test without situation settings（ experiment-a）,and their response time served as the index of the cognitive load.The field test（ experiment-b） was based on the latest mental health survey of 886 staff members who have passed the employment screening and been recruited by an institution. Response time was also taken as the index of the cognitive load and the relationship between cognitive load and personality traits was analyzed. Results The cognitive loads of the screening test were diverse under different conditions. In experiment-a,there was no significant difference among the cognitive loads of different questions,however,significant difference was observed in experiment-b. Among those participants,anxious subjects needed more time to response to irrelevant questions（ V1） and probes（ V2） while subjects who took the tests seriously and prudently spent relatively longer time（ t） to response to probes（ V2 and V3）. Moreover,subjects who had higher score in self-deception factor tended to have less cognitive load during the screening test. Conclusion Situational factors can affect the cognitive load in behavioral screening test,and the cognitive load is relevant to personalities.
