摘　　要：以中文阅读内容为实验材料,考察文本结构和个体认知风格对网上信息搜索绩效的影响。结果表明:(1)在信息规模较大的情况下,超文本的信息搜索时间少于纯线性文本,但迷路比线性文本严重;(2)在超文本情境下,被试更多地通过Back键来导航,而Home键相反;(3)没有发现个体认知风格的显著影响,认知风格对信息搜索绩效的效应需进一步探讨。The effects of text structure and cognitive style on information searching performance in WWW were exa-mined. It was found: (1)The searching time of linear text would be longer than hypertext when browsing a large information system, but the degree of disorientation in searching linear text was lower than in hypertext. (2)The Back button was pressed frequently when the hypertext was browsed, whereas the Home button was pressed frequently when the linear text was read.(3)The effects of cognitive style on information searching performance were not significant, which were not in accordance with our assumption and should be studied further.
