Despite the fundamental nature of tonic immobility in anxiety responses, surprisingly little empirical research has focused on the "freeze" response in humans. The present report evaluated the frequency and predictors of a freeze response in the context of a biological challenge. A nonclinical sample (N=404) underwent a 20-s inhalation of 20% CO(2)/balance O(2). Perceptions of immobility in the context of the challenge were reported in 13% of the sample, compared with 20% reporting a significant desire to flee. Subjective anxiety and panic during the challenge were associated with the freeze response, as were a number of anxiety symptom dimensions.
尽管紧张性不动在焦虑反应中具有基本性质，但令人惊讶的是，很少有实证研究关注人类的“冻结”反应。本报告评估了在生物应激情境下冻结反应的频率及其预测因素。一个非临床样本（N = 404）吸入了20%二氧化碳/其余为氧气的混合气体，持续20秒。在该应激情境中，13%的样本报告有不动的感觉，相比之下，20%的样本报告有强烈的逃跑欲望。应激过程中的主观焦虑和惊恐与冻结反应相关，一些焦虑症状维度也与之相关。
