摘要:目的：在生物反馈训练条件下，观测不同认知风格类型者焦虑相关生理指标的变化，探究生物反馈技术对不同认知风格类型者焦虑的治疗疗效的差异；为焦虑症的治疗提供参考依据，为不同人格特质的焦虑患者的治疗以及治疗者认识与了解人格类型对生物反馈技术的影响与作用提供一定参考。方法：用镶嵌图形测验（EFT）分离场独立型以及场依存型两种不同认知风格的个体，并通过焦虑自评量表(SAS)筛选出标准分大于50分的被试，设场独立组和场依存组，每组各8名被试。对16个被试施以为期三周每周两次的生物反馈训练，每位被试一次实验时间为30分钟。设对照组，不进行任何治疗。最后一次实验结束后再进行SAS测试，对比实验前后被试的心理指标有无变化。结果：实验组干预前后的肌电值（EMG）存在显著性差异（P＜0.05），脑电α波和SAS得分不存在显著性差异（P＞0.05）。实验后场独立组和场依存组SAS得分不存在显著性差异（P＞0.05）。结论：通过生物反馈训练能够有效地降低人们的焦虑值。生物反馈训练对不同认知风格类型者焦虑的治疗作用不存在显著性差异。

Abstract:On the condition of the biological feedback training, observing the changes of physiological indexes on different cognitive styles of anxiety, exploring the differences of biological feedback treatment technology on different cognitive styles of anxiety; to provide certain reference for the treatment of anxiety, and personality types on the influences and effects of biological feedback technology based on the treatment of different personality traits of anxiety patients and therapeutic understanding. Method: Applied Embedded Figures Test (EFT) to separateindividuals into "field dependence" and " field independence"cognitive style groups. Then chose 8 individuals who scored more than 50 in Self-Rating Anxiety Scale (SAS) among each group.  The 16 chosen individuals were subjected to a three-week, 30 minutes per-seesion biofeedback training. A control group received no treatments was also formed for comparision. When the last experimental session was over, both groups were given SAS test again to compare the pretest-posttest differences.Result: The experimental group showed significant pretest-posttest differences（P＜0.05）in physiological indicator Electromyography (EMG), but no significant differences in alpha brain wave and SAS scores （P＞0.05). The experimental "field dependence" group and "field independence" group received no significance in their SAS scores.（P＞0.05） Conclusion: Biofeedback training can effectively relief people's anxiety.
