Abstract

This literature review concentrates on a disregarded part of depressive disorders' symptomatology (especially concerning present-day classifications of mental disorders) that can be approached with a great number of experimental procedures. From the acoustical field the following findings are demonstrated and discussed: elevated click thresholds in auditory signal detection, changed ear asymmetry in dichotic click detection and differences in dichotic listening asymmetries according to symptomatology. The most important results from the so far investigated optical perceptual disturbances in depressive disorders are: breakdown of perceptual defence in the form of greater access to emotionally unpleasant stimuli referring to the tachistoscopic recognition of neutral/unpleasant words, impairments at near-distance assessments, disturbances in recognition and discrimination of facial emotions-especially concerning the perception of emotional chimeric faces. Interpretational attempts for these acoustical and optical disturbances of perception reach from developmental psychology to biological psychiatry. Changes in hemisphere functions hold the dominating position in this discussion. Up to now it remains open to what extent the reported results correlate with the clinical phenomenology of depressive disorders, of what diagnostic specifity they are and if the can be viewed with sufficient reliability as state marker and indicators for theraopeutical effects.

[抑郁症的声学和光学知觉障碍——实验研究结果综述]。
这篇文献综述集中在抑郁症的症状学中被忽视的部分(特别是关于当今精神障碍的分类),可以通过大量的实验程序来接近。从声学领域,我们论证并讨论了以下发现:听觉信号检测中的咔哒声阈值升高,二元咔哒声检测中的耳不对称性改变,以及根据症状的二元聆听不对称性的差异。迄今为止对抑郁症的视觉知觉障碍的研究得出的最重要的结果是:知觉防御的崩溃,表现为更容易接触到情绪上不愉快的刺激,这涉及到对中性/不愉快词汇的触觉识别,近距离评估的障碍,对面部情绪的识别和辨别障碍——尤其是对情绪嵌合面孔的感知。从发展心理学到生物精神病学,都在尝试解释这些听觉和视觉上的感知障碍。在这个讨论中,半球功能的变化占主导地位。到目前为止,报告的结果在多大程度上与抑郁症的临床现象相关,它们是什么诊断特异性,以及它们是否可以被视为具有足够可靠性的状态标记和治疗效果的指标,仍然是开放的。
