Cognitive Biases, Decreased Attention and Memory in Somatization Groups
Abstract
Cognitive processes of somatization group are considered to be relevant to the development and maintenance of somatization symptoms. The aim of this study was to confirm cognitive biases and as well as decreased attention and memory in somatization groups. A modified Stroop task, a delayed free recall task, and a recognition task using computer-presented word lists were performed to 17 college students with somatization tendencies and 17 normal college students. The results showed that the somatization groups had the significant Stroop interference effects for somatic-symptoms words. This result suggested that the somatization group have attentional biases for the somatic-symptoms words. Also, the somatization group showed significantly lower response bias index for somatic-symptom words than the normal group. However, the number of words correctly recalled, free-recall ratio, hit rate, stimulus sensitivity index of somatic-symptom words were not more or higher than those of positive words or neutral words, and the response bias index of somatic-symptom words was not lower than that of positive words or neutral words in the somatization group. Therefore, the hypothesis that the somatization group would have memory biases for the somatic-symptoms words was partially supported. In addition, the somatization groups had the decreased attention and memory. Finally, the significance and limitations of this study and the directions for future study were also discussed.
