According to cognitive theories, panic patients are assumed to display selective attention for feared bodily sensations. To date there has only been indirect evidence for this based on performance on reaction time tasks such as the modified Stroop task and the dot probe detection task. In the present study a more direct attempt was made to investigate whether panic patients show selective attention for feared sensations, in particular hyperventilatory sensations. A group of patients with panic disorder and a group of normal controls were compared on their performance on a reaction time task in which tones of different length had to be discriminated. During the task subjects were asked either to hyperventilate, to overbreathe under isocapnic conditions, or to make a neutral movement. No evidence for selective attention for hyperventilatory sensations was found. The article also discusses whether lack of finding interference during hyperventilation might be due to methodological issues.
根据认知理论,惊恐障碍患者被认为会对令人恐惧的身体感觉表现出选择性注意。迄今为止,基于诸如改良斯特鲁普任务和点探测任务等反应时任务的表现,仅有关于此的间接证据。在本研究中,进行了更直接的尝试,以调查惊恐障碍患者是否会对令人恐惧的感觉,特别是过度通气的感觉表现出选择性注意。将一组惊恐障碍患者和一组正常对照组在一项反应时任务中的表现进行了比较,该任务要求区分不同长度的音调。在任务过程中,要求受试者要么过度通气,要么在等碳酸条件下过度呼吸,要么进行中性动作。未发现对过度通气感觉存在选择性注意的证据。本文还讨论了在过度通气期间未发现干扰是否可能是由于方法学问题。
