Three groups of 5 chronically agoraphobic patients were treated by repeated exposure to cine film at weekly intervals for six weeks. A supraliminal group saw an agoraphobic film specially made for the study illustrating a range of phobic situations. A subliminal group viewed the same film at a level of illumination below the threshold of awareness. A control group saw a blank screen with no filmed material for the same length of time. The films were screened five times at each treatment and were alternated with neutral film shown under normal viewing conditions. Ratings of phobic and other symptoms were made by a separate assessor who was unaware of the patient's treatment. The supraliminal and subliminal groups improved significantly more than the control group with regard to phobic fears, avoidance, and overall assessment.
三组，每组5名慢性广场恐惧症患者，每周接受一次电影反复暴露治疗，为期六周。阈上组观看了一部专门为该研究制作的广场恐惧症电影，影片展示了一系列恐惧情境。阈下组在低于意识阈值的光照水平下观看同一部电影。对照组在相同时长内观看的是没有拍摄内容的空白屏幕。每次治疗时，电影播放五次，并与在正常观看条件下播放的中性电影交替播放。由一名不知道患者治疗情况的独立评估者对恐惧及其他症状进行评分。在恐惧、回避和总体评估方面，阈上组和阈下组的改善明显超过对照组。
