Abstract

We draw attention to studies indicating that phasic arousal increases interference effects in tasks necessitating the recruitment of cognitive control. We suggest that arousal-biased competition models such as GANE (glutamate amplifies noradrenergic effects) may be able to explain these findings by taking into account dynamic, within-trial changes in the relative salience of task-relevant and task-irrelevant features. However, testing this hypothesis requires a computational model.

摘要

我们注意到一些研究表明，阶段性觉醒会增加需要认知控制的任务中的干扰效应。我们认为，像 GANE（谷氨酸放大去甲肾上腺素能效应）这样的基于觉醒偏向的竞争模型，通过考虑与任务相关和不相关特征的相对显著性在试验内的动态变化，可能能够解释这些发现。然而，要验证这一假设需要一个计算模型。
