注意力能力、警觉反应、对感官刺激的定向以及对表现的执行监控被认为是独立而又相互关联的系统。这些操作在调节沿着进化阶梯的不同物种的行为中起着不可或缺的作用。每一个主要的注意力结构，警觉，定向，和执行监测，涉及显着的自主相关性反应性瞳孔放大（PD），心率和皮肤电导的变化证明。最近的技术进步，使用远程高分辨率记录可以允许识别的时空属性的自主反应，其特征的警报，定向，和执行监测网络在自由观看，无论自愿的性能。这可能会加深对自主调节在这些心理活动中的作用的理解，并可能加深我们对语言和非语言物种行为变化的理解。本研究的目的是探讨精神感觉PD反应之间的差异，在警觉，定向和执行冲突监测任务，以产生估计的并发蓝斑（LC）去甲肾上腺素能输入轨迹在健康成人使用注意力网络测试（ANT）。分析揭示了一个特定的结构模式的瞳孔反应：警觉的特点是由早期组件（Pa），其加速度使隐蔽定向，和执行控制证明了一个突出的晚期组件（Pe）。PD特征似乎是任务敏感的，允许探索的精神操作，而不考虑有意识的自愿反应。这些数据可能有助于开发旨在评估不同物种的自主反应的心理操作的研究。
Attention capacities, alerting responses, orienting to sensory stimulation, and executive monitoring of performance are considered independent yet interrelated systems. These operations play integral roles in regulating the behavior of diverse species along the evolutionary ladder. Each of the primary attention constructs—alerting, orienting, and executive monitoring—involves salient autonomic correlates as evidenced by changes in reactive pupil dilation (PD), heart rate, and skin conductance. Recent technological advances that use remote high-resolution recording may allow the discernment of temporo-spatial attributes of autonomic responses that characterize the alerting, orienting, and executive monitoring networks during free viewing, irrespective of voluntary performance. This may deepen the understanding of the roles of autonomic regulation in these mental operations and may deepen our understanding of behavioral changes in verbal as well as in non-verbal species. The aim of this study was to explore differences between psychosensory PD responses in alerting, orienting, and executive conflict monitoring tasks to generate estimates of concurrent locus coeruleus (LC) noradrenergic input trajectories in healthy human adults using the attention networks test (ANT). The analysis revealed a construct-specific pattern of pupil responses: alerting is characterized by an early component (Pa), its acceleration enables covert orienting, and executive control is evidenced by a prominent late component (Pe). PD characteristics seem to be task-sensitive, allowing exploration of mental operations irrespective of conscious voluntary responses. These data may facilitate development of studies designed to assess mental operations in diverse species using autonomic responses.
