Evidence was sought of an attentional bias toward a highly representative object of the bedroom environment in good, moderate, and poor (primary insomnia) sleepers. Using a flicker paradigm for inducing change blindness, the authors briefly presented a single scene comprising a group of bedroom environment and neutral objects to participants and then briefly replaced this scene with an identical scene containing a change made to either a bedroom environment or a neutral object. In a 3 x 2 entirely between-participants design, change-detection latencies revealed a sleep-related attentional bias in poor sleepers but not in good sleepers. A possible bias in moderate sleepers was also revealed. It is suggested that attentional bias has a role in the perpetuation and possibly precipitation of primary insomnia.
研究人员探寻了在睡眠状况良好、中等及较差（原发性失眠）的人群中，对卧室环境中具有高度代表性的物体是否存在注意力偏差的证据。作者采用闪烁范式来诱发变化盲视，向参与者短暂呈现包含一组卧室环境和中性物体的单个场景，然后将该场景短暂替换为一个相同的场景，其中对卧室环境或中性物体进行了一处改动。在一个3×2的完全被试间设计中，变化检测潜伏期显示，睡眠较差的人存在与睡眠相关的注意力偏差，而睡眠良好的人则没有。研究还发现中等睡眠质量者可能也存在偏差。研究表明，注意力偏差在原发性失眠的持续存在以及可能的诱发过程中起作用。
