Individuals with insomnia were exposed to a stressor (speech threat) prior to getting into bed and were instructed to think about the speech and its implications in either images (Image group, n = 14) or verbal thought (Verbal group, n = 17). Participants completed questionnaires about speech anxiety, arousal, and sense of resolution. Measures were taken of subjective (sleep diary estimates) and objective (actigraphy) sleep-onset latency. In the short term, the Image group reported more distress and arousal relative to those in the Verbal group. In the longer term, the Image group estimated that they fell asleep more quickly and, the following morning, reported less anxiety and more comfort about giving the speech compared with the Verbal group.
失眠患者在就寝前会面临一种压力源（言语威胁），并被要求以图像（图像组，n = 14）或言语思维（言语组，n = 17）的方式思考该言语及其影响。参与者完成了关于言语焦虑、唤醒和解决感的问卷调查。采用主观（睡眠日记估计）和客观（活动记录仪）测量入睡潜伏期。短期内，图像组比言语组报告了更多的痛苦和唤醒感。从长期来看，图像组估计他们入睡更快，并且与言语组相比，在第二天早上，他们报告在进行演讲时焦虑更少、更舒适。
