汉语句子阅读阈限的初步研究

本研究取90名被试，分成三个年龄组，以最小变化法为实验方法．向被试快速呈现4-12个汉字的句子．以被试能完全准确地复述出句子内容所需时问为因变量。实验结果表明．句子字数对阅读句子所需时间有极其显著的影响．特别是7个字以上的长句．阅读所需时间明显加长；而不同年龄组被试的阅渎速度仅在4、5、6个字的短句上存在差异；性别对阅渎速度的影响不显著。本实验的研究结果可为影视和广告字幕的呈现时间提供参考依据。

A PRELIMINARY STUDY ON THE THRESHOLD OF READING CHINESE SENTENCES UNDER THE TACHISTOSCOPIC CONDITION

With the method of minimal change, 90 participants divided into three groups were presented sentences consisting of 4 to 12 Chinese characters respectively, and then asked to report the sentences correctly. The results showed: the numbers of the words in one sentence significantly affected the reading time, and especially when the sentence consists of more than 7 characters, the reading time would be prolonged obviously. However, the reading time of the participants of different age groups just differed in the short sentences; genders had no influence on reading time. These results can provide reference for the proper duration of the caption presented on television and commercials.
