Normal adults, hearing-impaired preschool children, and normal-hearing mentally retarded children were assessed across repeated measures for auditory thresholds at 250 and 1000 Hz. Each subject's total performance across repeated measures was plotted by group by frequency relative to the last point of 100% correct response and interpolated thresholds. The results indicate that the steepness of the percentage of correct response performance curves and the variability of response performance above and below interpolated threshold were related to differences between the adult and child groups (mental age) and not between types of hearing populations (hearing sensitivity). The relationship between these results and experience with the signal is speculated.
对正常成年人、听力受损的学龄前儿童和听力正常的智力迟钝儿童进行了重复测量,以评估他们在250赫兹和1000赫兹时的听觉阈值。根据相对于100%正确反应的最后一点和内插阈值,按组和频率绘制了每个受试者在重复测量中的总体表现。结果表明,正确反应表现曲线的百分比陡度以及高于和低于内插阈值的反应表现变异性与成人组和儿童组(心理年龄)之间的差异有关,而与听力人群类型(听力敏感度)之间的差异无关。推测了这些结果与信号体验之间的关系。
