Dunst (1983) suggested that severely handicapped infants' intentional and unintentional communicative behaviors may be less interpretable or less easily "read" than are those of less handicapped infants. This hypothesis was tested in a sample of 15 pairs of mothers and their handicapped 11-month-old infants. As expected, the results indicated that coders agreed on the occurrence of an infant cue a lower percentage of the time when coding severely handicapped infants than when coding less handicapped infants.
邓斯特（1983年）提出，与残疾程度较轻的婴儿相比，重度残疾婴儿的有意和无意交流行为可能更难被解读或“读懂”。该假设在15对母亲及其11个月大的残疾婴儿样本中进行了测试。不出所料，结果表明，编码员对重度残疾婴儿发出提示信号的编码一致率低于对残疾程度较轻婴儿的编码一致率。
