儿童的纯音频率辨别力（FD）的心理声学阈值相对于成人是高的。已经表明，在单次（亚小时）训练后，有可能改善成人的FD阈值。为了确定儿童FD阈值是否可以通过训练得到改善，从而降低到成人水平，100名听力正常的6至11岁儿童和成人在1 kHz下接受了类似于1小时的FD任务训练。在训练开始时，四分之一的儿童参与者的FD阈值与幼稚成人（成人样亚组）相似。另外四分之一的人在训练过程中的某个时间点达到了成年人的阈值（可训练亚组）。对于其余的（nonadult样亚组），阈值没有达到那些天真的成年听众在任何时候在培训会议。亚组成员的影响与三个因素年龄，非语言智商和注意力。然而，在不同的小组，学习被发现不概括到一个不同的标准频率（4 kHz）或变量（巡回）演示范例。结果表明，这是可能的，一些儿童达到FD阈值与幼稚的成年人，无论是原生或经过有限的培训。(C)2008年，美国声学学会。
Psychoacoustic thresholds of pure tone frequency discrimination (FD) in children are elevated relative to those of adults. It has been shown that it is possible to improve FD thresholds in adults, following a single (subhour) training session. To determine whether FD thresholds in children may be improved by training and, consequently, reduced to adult levels, 100 normally hearing 6- to 11-year-old children and adults received similar to 1 h of training on a FD task at 1 kHz. At the start of training, a quarter of all child participants had FD thresholds that resembled those of naive adults (adult-like subgroup). Another quarter achieved thresholds that were adult-like at some point during training (trainable subgroup). For the remainder (nonadult-like subgroup), thresholds did not reach those of naive adult listeners at any point in the training session. Subgroup membership was linked to the influence of three factors-age, nonverbal IQ, and attention. However, across subgroups, learning was found not to generalize to either a different standard frequency (4 kHz) or a variable (roving) presentation paradigm. The results indicate that it is possible for some children to achieve FD thresholds comparable to those of naive adults, either natively or after limited training.
