Research in the field of speech production pathology is dominated by describing deficits in output. However, perceptual problems might underlie, precede, or interact with production disorders. The present study hypothesizes that the level of the production disorders is linked to level of perception disorders, thus lower-order production problems (such as childhood apraxia of speech; CAS) are linked to lower-order perception problems and higher-order production problems (phonological disorder; PD) are linked to higher-order perception problems. For this, various perception tasks were administered (non-word auditory discrimination task, word rhyming task, categorical classification, and discrimination task) in children with CAS, PD, or a mixture. The results show that children with PD only show higher-order perception problems, whereas children with CAS have difficulties on both lower- and higher-order perception tasks. In children with CAS, difficulties at lower-order processes might affect the higher-order processes in development. Furthermore, significant correlations were found between production and perception scores at different levels. Thus, a link between perception and production seems to be evident.
言语产生病理学领域的研究主要集中在描述输出方面的缺陷。然而，感知问题可能是产生障碍的潜在原因、先于产生障碍出现，或者与产生障碍相互作用。本研究假设，产生障碍的程度与感知障碍的程度相关，因此，低阶产生问题（如儿童言语失用症；CAS）与低阶感知问题相关，高阶产生问题（语音障碍；PD）与高阶感知问题相关。为此，对患有CAS、PD或两者皆有的儿童进行了各种感知任务（非单词听觉辨别任务、单词押韵任务、分类任务和辨别任务）。结果表明，患有PD的儿童仅表现出高阶感知问题，而患有CAS的儿童在低阶和高阶感知任务上均有困难。在患有CAS的儿童中，低阶过程中的困难可能会影响高阶过程的发展。此外，在不同水平上的产生和感知分数之间发现了显著的相关性。因此，感知与产生之间的联系似乎是明显的。
