注意力可以集中在外部环境上，也可以集中在内部思想上，并且可能会因来自外部或内部来源的不相关信息的干扰而脱轨。然而，很少有研究探讨不同注意力方向和不同干扰源之间相互作用的本质和潜在机制。我们研究了外部注意力如何影响外部注意力和内部注意力，如何调节内部注意力，以及这些相互作用是否受到健康衰老的影响。健康的年轻人和老年人既执行了外部导向的视觉检测任务，又执行了内部导向的心理旋转任务，无论有没有通过耳机传递听觉声音。我们发现，听觉声音的增加会导致年轻人和老年人在视觉辨别任务中的任务表现显着下降，并且伴随着所报告的干扰类型的转变（从内部到外部）。在面向内部的任务中，听觉声音仅影响老年人的表现。这些结果表明，外部干扰的影响对内部注意力导向任务的表现与外部注意力导向任务的表现有不同的影响。此外，内部分心会受到外部声音的存在和内部分心抑制增加的影响。
Attention can be oriented externally to the environment or internally to the mind, and can be derailed by interference from irrelevant information originating from either external or internal sources. However, few studies have explored the nature and underlying mechanisms of the interaction between different attentional orientations and different sources of interference. We investigated how externally- and internally-directed attention was impacted by external distraction, how this modulated internal distraction, and whether these interactions were affected by healthy aging. Healthy younger and older adults performed both an externally-oriented visual detection task and an internally-oriented mental rotation task, performed with and without auditory sound delivered through headphones. We found that the addition of auditory sound induced a significant decrease in task performance in both younger and older adults on the visual discrimination task, and this was accompanied by a shift in the type of distractions reported (from internal to external). On the internally-oriented task, auditory sound only affected performance in older adults. These results suggest that the impact of external distractions differentially impacts performance on tasks with internal, as opposed to external, attentional orientations. Further, internal distractibility is affected by the presence of external sound and increased suppression of internal distraction.
