信息加工效率与阅读的关系研究

对23名大学生进行知觉广度、记忆广度和阅读理解的多项测验，探求知觉、记忆加工效率与不同语言阅读成绩和阅读眼动特性之间的关系。结果发现：低水平的视觉符号方向信号知觉广度与阅读不存在明显的关系，从眼跳幅度指标上反映出右侧知觉广度大的被试对第二语言加工难度更为敏感。短时记忆和工作记忆能力对阅读的影响主要反映在眼跳幅度方面，与单个注视点获取的信息量有关，但与课文理解水平的关系不明显。短时记忆能力强的被试在眼跳幅度上以及第二语言言语工作记忆弱的被试在注视时间上均出现语言差异效应。

The Relationship between Perception,Memory and Reading

An experiment was conducted to examine the influence of perception, memory on reading different languages. Twenty- three college students participated in this experiment by measuring perceptual span, digit span, reading span and reading comprehension. Their perfor- mances of reading comprehension were measured and eye movements were monitored during reading. And their reading comprehension perfor- mance, reading time, words recognition and eye movements during reading were analyzed according to perceptual and memory spans. The result suggested： first, the perceptual information processing of lower level had no obvious relationship with test comprehension, while the subjects with larger right perceptual span were proved to be more sensitive to the difficulty of information processing. Second, the influence of short- term memory （STM） and working memory capacity （WMC） which had obscure relationships with test comprehension showed their acute rela- tionship with saccadic amplitude in reading which reflected the amount of information obtained in a single fixation point. Third, the reports also told that the subjects with higher STM capacity and weaker verbal WMC in second language processing were mere sensitive to the difficulty of information processing respectively on saccadic amplitude and the first fixation time.
