A population was used of 18 children (6--13 yrs median = 9--1 yrs) enrolled in a psychiatric day care center where they received daily educational instruction and on two occasions per week they received psychotherapy. Intelligence was normal (Wechsler Full Scale mn = 96). Ss were individually given the Goldman-Friscoe-Woodcock Test of Auditory Discrimination both in quiet and in the noise condition. Median scores in quiet and in noise were both lower than general forms for these ages, lying indeed within the range of "poor discrimination" for the GFW, but the relative scores for the quiet and the noise conditions did not differ significantly from the pattern for normal children. However, 6 of the 18 Ss scored relatively better in noise than in quiet, and a Wilcoxon Matched-Pairs Signed-Ranks test demonstrated that this was a significantly larger number (p less than .025, one-tailed test) than in the general population. Explanations were offered in terms of a reduction of internal noise, and of relative attention on the part of emotionally disturbed children.
研究对象为18名儿童（年龄6 - 13岁，中位数 = 9.1岁），他们就读于一家精神科日间护理中心，在那里接受日常教育指导，每周还接受两次心理治疗。智力正常（韦氏全量表智商中位数 = 96）。受试者分别在安静和噪声环境下接受戈德曼 - 弗里斯科 - 伍德科克听觉辨别测试。安静环境和噪声环境下的中位数分数均低于这些年龄段的一般水平，实际上处于GFW测试“辨别能力差”的范围内，但安静环境和噪声环境下的相对分数与正常儿童的模式没有显著差异。然而，18名受试者中有6人在噪声环境下的得分相对高于安静环境，威尔科克森配对符号秩检验表明，这一数量显著多于一般人群（p < 0.025，单尾检验）。研究从内部噪声减少以及情绪困扰儿童相对注意力方面给出了解释。
