摘要

通过对小学三、六年级儿童在 2 种不同混响时间和 3 种不同干扰噪声级条件下进行汉语双音节词语的视觉短时记忆行为的测试,探讨了噪声和混响时间对不同年龄段儿童对汉语词语的视觉短时记忆的影响,并比较了混响和噪声条件下儿童听觉记忆和视觉记忆行为之间的差异. 结果表明:干扰噪声级和儿童年龄对儿童在教室内的视觉短时记忆行为均有显著影响;随着干扰噪声级的降低、混响时间的缩短以及儿童年龄的增大,儿童对汉语词语的视觉短时记忆得分增加;噪声和混响对听觉记忆的影响较视觉记忆的影响大,但随着噪声级的降低和混响时间的缩短,视觉记忆和听觉记忆的记忆得分差异减小.

Abstract

Visual short-term memory behaviors for Chinese bi-syllable phrases were tested on Grades 3 and 6 chil- dren under the conditions of two different reverberation times and three different interference noise levels,and the effects of noise and reverberation time on the visual short-term memory for Chinese phases of children with different ages were investigated.Then,the differences between auditory memory and visual memory behaviors of children in reverberation and noise environments were analyzed in a comparative way.The results show that (1) both interfer- ence noise level and age have significant effects on the visual short-term memory of children in classroom; (2) with the decrease of interference noise level,the shortening of reverberation time and the increase of children's age,the visual short-term memory scores of children for Chinese phrases increase; and (3) the effects of noise and reverber- ation time on auditory memory behavior are greater than those on visual memory,and the difference in scores be- tween the auditory and visual memory behavior decreases with the decrease of noise level and with the shortening of reverberation time.
