The present study describes a tactual object matching task based on the study of Lederman and Klatzky (1987) for the dimensions Exact shape, Weight, Volume and Texture. Participants were congenitally blind children and their sighted classmates, congenitally blind adults and sighted adults. To study a possible effect of familiarity the task was performed four times. Based on Millar's CAPIN (Convergent Active Processes in Interrelated Networks) model of spatial processing (Millar, 1994) it was thought that this manipulation would add redundant information to the experiment from which the children and blind participants could benefit. The results showed that accuracy was affected more by age than visual status, especially for the dimension Exact Shape. With regard to response times, children were in most cases faster than adults, especially the sighted adults. Familiarization had a significant effect on response times for all dimensions. Extra exercise only increased accuracy for the dimension Texture. These results were generally in line with the CAPIN model.
本研究描述了一项基于莱德曼和克拉茨基（1987年）研究的触觉物体匹配任务，涉及精确形状、重量、体积和质地等维度。参与者包括先天性失明儿童及其有视力的同学、先天性失明成年人和有视力的成年人。为了研究熟悉度可能产生的影响，该任务进行了四次。基于米勒的空间处理CAPIN（相互关联网络中的收敛主动过程）模型（米勒，1994年），认为这种操作会给实验增加冗余信息，儿童和盲人参与者可能从中受益。结果表明，准确性受年龄的影响大于视觉状态，尤其是在精确形状维度上。关于反应时间，儿童在大多数情况下比成年人快，尤其是有视力的成年人。熟悉度对所有维度的反应时间都有显著影响。额外练习仅提高了质地维度的准确性。这些结果总体上与CAPIN模型一致。
