Abstract

In two related experiments on recognition-on touch and audition-accuracy rates were obtained from congenitally blind subjects and compared with those for normally sighted subjects. In Exp. 1, 5 blind subjects inspected, i.e., handled, 150 common objects and were tested after a delay of 7 days. In Exp. 2, 9 blind subjects listened to 194 naturalistic sounds and were also tested after a 7-day delay. Accuracy of tactile recognition for the blind was 89.4% while it was 87.9% for the normally sighted. Sound recognition by blind subjects was 76.6% and for the normally sighted it was 78.4%. Neither difference was statistically significant.

摘要

在两项相关实验中，分别针对触觉识别和听觉识别进行研究，从先天性失明受试者那里获得准确率，并与正常视力受试者的准确率进行比较。在实验1中，5名失明受试者检查（即触摸）了150个常见物体，并在7天的延迟后进行测试。在实验2中，9名失明受试者聆听了194种自然声音，同样在7天延迟后进行测试。失明者触觉识别的准确率为89.4%，而正常视力者为87.9%。失明受试者的声音识别率为76.6%，正常视力者为78.4%。两者差异均无统计学意义。
