The present study examined the ability of Type A and Type B subjects to sustain attention during a 40-min visual vigilance task. It was predicted that Type A subjects would perform better than Type B subjects and that the performance of both groups would be related to the frequency of daydreams during the vigil. Type A subjects outperformed Type B subjects with regard to perceptual sensitivity (A') and number of signal detections. Although both groups reported an increase in the number of their daydreams as the vigil progressed, Type A subjects reported fewer daydreams during each period of watch than did Type B subjects. In addition, an inverse relationship was found between the number of signal detections and the frequency of daydreams.
本研究考察了A型和B型受试者在一项40分钟视觉警觉任务中保持注意力的能力。研究预测，A型受试者的表现会优于B型受试者，且两组的表现都与警觉期间白日梦的频率有关。在感知敏感度（A'）和信号检测数量方面，A型受试者的表现优于B型受试者。尽管两组都报告说，随着警觉时间的推进，他们的白日梦数量有所增加，但在每个观察时间段内，A型受试者报告的白日梦数量都比B型受试者少。此外，还发现信号检测数量与白日梦频率之间存在负相关关系。
