目前的研究检查瞳孔反应（包括试验前基线和阶段性反应）将准确跟踪蓝斑去甲肾上腺素（LC-NE）功能理论预测的注意力丧失的程度。参与者进行了持续的注意力任务，而学生的反应被连续记录。在任务过程中，参与者定期接受思维探针，以确定他们是否在执行任务。结果表明，瞳孔反应可以准确区分开任务状态和关任务状态。重要的是，试验前的基线瞳孔反应区分了不同类型的注意力缺失，与集中状态相比，注意力不集中和走神状态与平均较小的试验前基线瞳孔直径相关，而分心状态与平均较大的试验前基线瞳孔直径相关。这些结果支持瞳孔直径对不同类型的注意力缺失敏感的观点，这可能与不同的LC-NE模式相关。
The current study examined the extent to which pupillary responses (both pretrial baseline and phasic responses) would accurately track lapses of attention as predicted by theories of locus coeruleus norepinephrine (LC-NE) functioning. Participants performed a sustained attention task while pupil responses were continuously recorded. Periodically during the task, participants were presented with thought probes to determine if they were on or off task. The results suggested the pupillary responses accurately distinguished on from off-task states. Importantly, pretrial baseline pupil responses distinguished different types of lapses of attention, with inattentive and mind-wandering states being associated with small pretrial baseline pupil diameters on average and distracted states being associated with larger pretrial baseline pupil diameters on average compared to focused states. These results support the notion that pupil diameter is sensitive to different types of lapses of attention which may be associated with different LC-NE modes.
