摘要
随着老龄化进程的加剧,老年人的需要得到了越来越多的关注。阅读是老年人重要的认知活动之一,但老年人阅读时的体验并没有得到足够的关注。前人研究已经证明文本的排版因素对于阅读有着重要的影响,但是字体大小和行距因素对于文本阅读影响的研究结论并不一致,同时针对汉语文本材料的研究也不足。本研究结合眼动分析技术和阅读主观体验分析字体大小因素与行距因素对城市低龄老人阅读的影响。研究采用2(字体大小:20磅vs24磅)X2(行距:1倍行距vs 1.5倍行距)二因素重复测量设计。以28名经过视力和认知能力筛查的城市低龄老人(60-69周岁)为有效被试,采用由德国SMI公司开发的RED型桌面式眼动仪记录被试的眼动轨迹,使用8篇经过同质被试评定过的报纸材料作为实验材料(材料的难度与主题熟悉性不存在显著差异),材料字体均为宋体。研究发现:(1)字体大小效应显著,随着字体大小的增加,老年人阅读时的注视次数会增加,平均注视时间会缩短,眼跳距离更短;阅读速度会加快,总注视时间缩短;(2)较宽的行距条件下,老年人的阅读速度更快,总注视时间更短;(3)大号字体和较宽的行间距能够显著改善老年人阅读时的主观体验。
With the aging society process intensified,researchers pay more and more attention of the demand of elderly people. The study of reading experience of the old hasn`t been drawn enough attention by researchers, even though reading is very important among the cognitive activity. Previous researchers studied the effects of typographic variables on eye-movement measures in reading Chinese, but the effect between front size and spacing for elderly people is still unsure. To investigate the most efficient way to represent text in reading Chinese, two typographic variables, font size(0.705 /20 pound and 0.806/24 pound), line spacing(one line and one and half line) were manipulated. Thirty-two native unban low-age senior Chinese readers, aged 60 to 69, were asked to read 8 simple passages and then answer four multiple-choice questions. The factor of difficulty(F(7,136)=0.875,p=0.534) and familiarity(F(7,128)=0.862,p=0.687) of each text was manipulated to equal. All of the texts were displayed on Song font style.Participants were seated 60 cm from the screen, and head movements were minimized through the use of a chin rest. Eye movements were recorded with an iV iew X RED manufactured by Senso-Motoric Instruments(SMI). The eye tracker sampled at 250 Hz.The eye-movement analyses revealed that text in larger-size characters had shorter fixation duration, fewer fixations and faster reading rate than text in small-size characters. While under the wider line spacing condition, the elderly read faster with shorter total fixation time than in narrow line spacing. Considering the reading experience, the subjects prefer larger charter and wider line-spacing condition.
