文本结构和时间应激对网页阅读绩效的影响

探讨了文本结构和时间应激对网页阅读绩效的影响效应。采用 2× 3被试间设计 ,自变量为文本结构和阅读时间 ,因变量为找到相关信息的时间及途径的额外节点数。结果发现 ,主效应及交互作用的影响均十分显著。其中 ,当阅读时间为 10和 2 0min时 ,超文本阅读的绩效均显著低于线性文本 ,而在 30min时两者无显著差异 ;对超文本 ,三种阅读时间的效应存在显著差异 ,而对线性材料 ,阅读时间的效应无显著差异。结论 :时间应激对超文本阅读绩效的影响更为明显

A Study of the Practice Effect of Cognitive Process in Categorical and Metric Spatial Relation Encoding

The effects of text structure and time stress on web reading performance were examined. The 2*3 experiment design was employed. The independent variables were text structure and reading time respectively. The mean time for seeking related information and the mean number index of extra node passed by were employed as dependent variables. It was found that text structure, reading time and their interaction had significant effects on the web reading performance. In other words, the efficiency of hypertext reading was significantly lower than linear text reading when reading time was set for 10 or 20 min, whereas they were not significantly different from each other when reading time was set for 30 min. There were significantly differences in reading performance among three reading times for hypertext, whereas there was non for linear text material. It was concluded that time stress exercised a notable impact on hypertext reading in particular.
