内隐联想测验（IAT）是社会心理学领域内的一种内隐评价工具。这项任务的参与者完成了要求他们对类别和属性（例如，面孔的类型和文字的类型）。对共享某些响应组合的不同块中的反应时间进行平均，然后从具有其他响应组合的块中减去，然后归一化，其结果被视为指示朝向或远离给定类别的隐式评估的度量。这种方法的一个假设是响应时间分布的平稳性，或者至少响应时间的时间动态在理论上是不相关的。在这里，我们测试这些假设，检查在何种程度上的响应时间内的IAT块的变化，如果是这样，如何变化的轨迹是有意义的外部措施。使用多个数据集，我们证明了会话内IAT分数的变化。此外，我们表明，可分离的组成部分的IAT性能的轨迹可能与理论上不同的过程中的认知偏差以及行为。目前的工作提出的证据表明，IAT的性能变化的任务，而未来的工作是需要充分评估这些时间动态的影响。
The Implicit Association Test (IAT) is employed in the domain of social psychology as a measure of implicit evaluation. Participants in this task complete blocks of trials where they are asked to respond to categories and attributes (e.g., types of faces and types of words). Reaction times in different blocks sharing certain response combinations are averaged and then subtracted from blocks with other response combinations and then normalized, the result of which is taken as a measure indicating implicit evaluation toward or away from the given categories. One assumption of this approach is stationarity of response time distributions, or at a minimum, that temporal dynamics in response times are not theoretically relevant. Here we test these assumptions, examine the extent to which response times change within the IAT blocks and, if so, how trajectories of change are meaningful in relation to external measures. Using multiple data sets we demonstrate within-session changes in IAT scores. Further, we demonstrate that dissociable components in the trajectories of IAT performance may be linked to theoretically distinct processes of cognitive biases as well as behaviors. The present work presents evidence that IAT performance changes within the task, while future work is needed to fully assess the implications of these temporal dynamics.
