An attempt was made to examine the encoding of visually presented additive and nonadditive digital material and its processing by deaf and hearing Ss. A 2 X 3 X 4 within-Ss design consisting of groups (45 deaf and 45 hearing Ss), numeral sets (additive, lower additive, and additive random), and recall intervals (0, 3, 9, and 12 seconds) was used. Results showed better recall of the additive set in which the third digit was the sum of the first two (e.g., 5-3-8) than other sets. Although the hearing Ss recalled better than the deaf Ss at short delay, performance of both groups deteriorated with increase in retention intervals. Implications of this study are related to the problem of automatic processing in short-term recall and how it is sensitive to the structure of the sequence of a numeral set.
研究人员试图检验视觉呈现的加法和非加法数字材料的编码方式，以及聋人和听力正常的被试对其的处理情况。实验采用了被试内2×3×4设计，包括组别（45名聋人被试和45名听力正常的被试）、数字集（加法、低加法和加法随机）以及回忆间隔（0、3、9和12秒）。结果显示，对于第三位数字是前两位数字之和的加法数字集（例如5 - 3 - 8），被试的回忆效果优于其他数字集。虽然在短延迟条件下，听力正常的被试比聋人被试回忆得更好，但随着保持间隔的增加，两组被试的表现均有所下降。本研究的意义与短期回忆中的自动加工问题以及它对数字集序列结构的敏感性有关。
