集中注意力的能力是许多日常任务取得成功的基础，但自愿的注意力不能持续很长一段时间。在实验室中，持续性注意力失败表现为随着工作时间的增加，知觉敏感度下降，这被称为警觉性下降。我们调查了通过训练(约5小时/天，持续3个月)在持续注意力方面的改善，其中包括冥想练习，涉及对选定刺激(例如，参与者的呼吸)的持续选择性注意力。参与者被随机分配到先接受培训(n=30)或作为等待名单控制组并接受培训(n=30)。训练改善了视觉辨别能力，这与感知敏感度的提高和持续视觉注意过程中的警觉性提高有关。这些结果与警觉的资源模型一致，表明知觉改善可以减少目标歧视强加的资源需求，从而更容易维持自愿注意。
The ability to focus one’s attention underlies success in many everyday tasks, but voluntary attention cannot be sustained for extended periods of time. In the laboratory, sustained-attention failure is manifest as a decline in perceptual sensitivity with increasing time on task, known as the vigilance decrement. We investigated improvements in sustained attention with training (~5 hr/day for 3 months), which consisted of meditation practice that involved sustained selective attention on a chosen stimulus (e.g., the participant’s breath). Participants were randomly assigned either to receive training first (n = 30) or to serve as waiting-list controls and receive training second (n = 30). Training produced improvements in visual discrimination that were linked to increases in perceptual sensitivity and improved vigilance during sustained visual attention. Consistent with the resource model of vigilance, these results suggest that perceptual improvements can reduce the resource demand imposed by target discrimination and thus make it easier to sustain voluntary attention.
