目的:研究癌症患者对情绪信息的注意偏向及其加工机制。方法:通过点探测任务探究不同类型的刺激图片和呈现时间对癌症患者组和健康对照组被试注意偏向的影响。结果:①患者组对负性情绪有注意偏向,对正性情绪有注意逃避。②刺激呈现500ms时,患者组对负性情绪有注意偏向,对正性情绪有注意逃避,且差异显著;呈现时间为1250ms时,对负性情绪有注意偏向,对正性情绪有注意逃避,但两者无显著差异。③癌症患者的注意偏向存在性别差异,男性患者比女性患者对负性情绪信息的注意偏向更加明显。结论:癌症患者对负性情绪存在注意偏向,且主要存在于认知加工的初始阶段;男性患者比女性患者对负性情绪信息的注意偏向水平更高。
Objective: To study the attention bias of cancer patients to emotional information and its processing mechanism. Methods: Through the point detection task, we investigated the effects of different types of stimulation pictures and presentation time on the attention bias of cancer patients and healthy controls. Results: ① The patient group had a negative bias and had a positive effect of avoiding the positive emotion. ② When the stimulus showed 500ms, the patient group had the attention bias towards the negative emotions and the positive emotions with attentional evasion, and the difference was significant. When the presentation time was 1250ms, the patient had the negative bias and the positive emotions, But no significant difference between the two. ③ cancer patients pay attention to bias there is gender differences, male patients than female patients tend to pay more attention to negative emotional information. CONCLUSIONS: Cancer patients have a negative bias and tend to be at the initial stage of cognitive processing. Men tend to be more biased towards negative emotional information than female patients.
