【摘要】：在注意控制理论的基础上,分别探讨特质焦虑和状态焦虑对注意网络功能的影响,同时考查认知负荷是否是焦虑干扰注意网络功能的调节变量。研究一,52名被试参与试验,根据特质焦虑得分高低,将被试分为高特质焦虑组和低特质焦虑组。采用注意网络测验任务(ANT)对注意网络功能进行测量,并使用N-Back任务对认知负荷进行操控。结果显示:高认知负荷条件下的注意网络功能效率高于低认知负荷条件;认知负荷是焦虑影响执行控制功能的调节变量。研究二,使用电击和噪音2种惩罚方式,以及限时反应、摄像等方法诱发状态焦虑;使用ANT任务测量注意网络功能;使用N-Back任务对认知负荷进行操控。结果显示:高状态焦虑组的注意网络功能效率低于低状态焦虑组;高认知负荷条件下的警觉功能和执行控制功能效率高于低认知负荷条件;状态焦虑和认知负荷的交互作用不显著。结论:(1)特质焦虑干扰目标导向的注意系统,状态焦虑干扰刺激驱动的注意系统;(2)认知负荷可以提高警觉功能和执行控制功能效率;(3)认知负荷是特质焦虑影响执行控制功能的调节变量。
[Abstract]:On the basis of attention control theory, the effects of trait anxiety and state anxiety on attention network function are discussed, and whether cognitive load is the regulating variable of anxiety interference attention network function is investigated. According to the score of trait anxiety, 52 subjects were divided into high trait anxiety group and low trait anxiety group. Attention network test task (ant) was used to measure attention network function and N-Back task was used to control cognitive load. The results show that the efficiency of attention network is higher than that of low cognitive load, and cognitive load is the regulating variable of anxiety affecting executive control function. Second, state anxiety was induced by two kinds of punishment methods, such as electric shock and noise, time-limited reaction, camera, etc.; ant task was used to measure attention network function; N-Back task was used to control cognitive load. The results showed that the efficiency of attention network function in high state anxiety group was lower than that in low state anxiety group, the alertness and executive control function efficiency in high cognitive load group was higher than that in low cognitive load group. The interaction between state anxiety and cognitive load was not significant. Conclusion: (1) trait anxiety interferes with goal-oriented attention system, State anxiety interferes with stimulus-driven attention system; (2) cognitive load can improve the efficiency of alertness and executive control; (3) cognitive load is the regulatory variable that trait anxiety affects executive control function.
