现在众所周知，缺乏注意力会使人们无法意识到明显，持久和动态的刺激，例如一个穿着大猩猩的可见人或一个声称是大猩猩的可听见的人。然而，触摸是否会受到这种极端的无意影响的问题仍然是开放的。在这里，我们提出了两个实验的证据，即缺乏注意力会使人们对持续3.5秒并在六个不同皮肤位置移动的触觉刺激“麻木”，建立了“持续的无意麻木”的新现象。鉴于触觉信息处理比听觉或视觉处理更直接的说法，这种效果特别令人惊讶，这表明触觉意识可能不会受到我们在这里观察到的注意力调节的影响。研究结果也有重要的应用意义，因为触觉警告在日常信息传递系统中越来越普遍。这项研究表明，当人们注意其他事情时，他们可能会错过在皮肤上移动的六次触摸。这是一个重要的发现，因为触觉警告在日常信息传递系统中越来越普遍（例如，对于汽车中的车道偏离警告），因为这表明如果这些警告落在人的注意力焦点之外，则这些警告可能并不总是被注意到。
It is now well-known that a lack of attention can leave people unaware of clearly-noticeable, long-lasting and dynamic stimuli, such as a visible person dressed as a gorilla or an audible person claiming to be a gorilla. However, the question of whether touch can ever be susceptible to such extreme inattentional effects remains open. Here, we present evidence across two experiments that the absence of attention can leave people “numb” to the presence of a tactile stimulus that lasts for 3.5 s and moves across six different skin locations, establishing the new phenomenon of “sustained inattentional numbness.” The effect is particularly surprising in light of claims that tactile information processing is more direct than auditory or visual processing, which would suggest that tactile awareness might not be open to attentional modulation of the type that we observe here. The findings also have important applied implications given the increasing prevalence of tactile warnings in everyday information delivery systems. This study demonstrates that people can miss a sequence of six touches moving across their skin when they are paying attention to something else. This is an important finding given the increasing prevalence of tactile warnings in everyday information delivery systems (e.g., for lane departure warnings in cars), because it suggests that these warnings may not always be noticed if they fall outside a person’s focus of attention.
