The most definitive evidence about any aspect of stuttering is that listeners are unable to judge unit-by-unit occurrences of it acceptably. This result has been replicated repeatedly in every decade for a half century. Nonetheless, for virtually all research and most clinical practice, stuttering has been defined perceptually as if listeners could identify it accurately. Reasons for this state of affairs and its implications for therapy, theory, and research are analyzed. An alternative speech production definition with its implications is proposed. Further, a diagnostic method of validating authentic stuttering is described, as is an objective for fluency-skill therapy that reduces rather than reinforces avoidance behavior.
关于口吃任何方面的最确凿证据是，听众无法令人满意地逐单元判断口吃的发生情况。在半个世纪里，每十年都反复得到这一结果。然而，几乎对于所有研究和大多数临床实践而言，口吃在认知上的定义就好像听众能够准确识别它一样。分析了这种情况的原因及其对治疗、理论和研究的影响。提出了一种替代性的言语产生定义及其影响。此外，还描述了一种验证真性口吃的诊断方法，以及一种减少而非强化回避行为的流利技能治疗目标。
