背景资料：注意力偏差变异性被认为是衡量注意力朝向和远离威胁相关信息的波动，并且在情感障碍中升高。然而，最近的证据表明，注意偏差的变异性可以量化一般的反应时的变异性，而不是注意偏差behaviorsess.Methods：目前的研究计算“注意偏差变异性”从两个概念上无关的认知任务：点探测任务（测量注意偏差）和箭头侧翼任务（测量认知控制）。然而，当一般反应时间的变异性得到控制，注意力偏差的变异性在任务之间不再相关。此外，控制一般反应时变异性时，注意力偏差变异性措施的可靠性下降。最后，虽然注意力偏差变异计算的点探测任务最初与焦虑症状，这种关联不再显着控制一般反应时间variability.Limitations：我们的样本是由高特质焦虑的个人。复制在临床samples是warranted.Conclusions：这些研究结果共同提供了强有力的经验证据，注意偏差的变异性是不是一个有效的措施，注意力相关的行为，但反映一般反应时间的变异性更广泛。
Background: Attention bias variability is thought to measure fluctuations in attention towards and away from threat-related information and is elevated in affective disorders. However, recent evidence suggests that attention bias variability may quantify general reaction time variability rather than attention bias behavior per se.Methods: The current study calculated "attention bias variability" from two conceptually unrelated cognitive tasks: the dot-probe task (measuring attentional bias) and the arrow flanker task (measuring cognitive control).Results: Attention bias variability measures were correlated across these unrelated tasks. Yet, when general reaction time variability was controlled, attention bias variability across tasks was no longer correlated. In addition, the reliability of attention bias variability measures decreased when controlling for general reaction time variability. Finally, although attention bias variability calculated from the dot-probe task initially correlated with anxious symptoms, this association was no longer significant when controlling for general reaction time variability.Limitations: Our sample was comprised of high trait anxious individuals. Replication in clinical samples is warranted.Conclusions: These findings collectively provide strong empirical evidence that attention bias variability is not a valid measure of attention-related behavior, but reflective of general reaction time variability more broadly.
