摘要
目的探讨老年人在汉语阅读中的知觉广度。方法采用呈现随眼动变化技术,设定的可视窗口分为6个水平(无预视、R1、R2、L1R1、L1R2和整行条件),以双字词组成的句子作为阅读材料,对18名老年人在汉语阅读中的知觉广度进行研究。结果①在确定知觉广度左侧范围的比较中,各眼动指标差异均不显著;②在确定知觉广度右侧范围的比较中,无预视条件与R2条件在阅读时间、注视次数、阅读速度上差异显著,R1与R2条件在各指标上均不显著。结论①老年人汉语阅读知觉广度的范围为注视点及注视点右侧1个词;②老年人汉语阅读知觉广度具有不对称性。
Objective To explore the size of the perceptual span in older adults during the Chinese sentence reading.Methods The participants were eighteen older adults with normal or corrected-to-normal vision.The eye movement contingent display change technique was used in theis experiment.Results All the sentences were composed by two character words.There were six different display conditions.They were no preview,R1,R2,L1R1,L1R2 and whole line condition.Conclusions ①The perceptual span of older adults in reading Chinese is extended from fixated word to one word to its right.②The perceptual span of older adults in reading Chinese is also asymmetric.
