Categories of Auditory Performance (CAP) is an index consisting of eight performance categories arranged in order of increasing difficulty. It has been used to categorize 53 children who had been deafened below the age of 3. The children were assessed by means of the CAP before implantation, and over the following 3 years. Before implantation, only 2 of the children showed awareness of environmental sounds; immediately after initial tuning, all children showed awareness of environmental sounds, and 50% showed awareness of speech sounds. Their auditory receptive abilities gradually developed over the 3-year period, and by the 3-year assessment interval, 80% were understanding phrases without lipreading, and 40% were understanding conversation. Using these data, we predict that 90% of such children will understand conversation without lipreading 5 years after initial tuning.
听觉表现类别（CAP）是一个由八个表现类别组成的指标，这些类别按照难度递增的顺序排列。它被用于对53名3岁前失聪的儿童进行分类。这些儿童在植入前以及随后的3年里通过CAP进行评估。植入前，只有2名儿童表现出对环境声音的意识；初次调试后，所有儿童都表现出对环境声音的意识，50%的儿童表现出对语音的意识。他们的听觉接受能力在3年期间逐渐发展，到3年评估期时，80%的儿童在不借助唇读的情况下能够理解短语，40%的儿童能够理解对话。利用这些数据，我们预测，此类儿童在初次调试5年后，90%将在不借助唇读的情况下理解对话。
