摘　　要：实验探讨了时间应激对不同结构超文本信息搜索绩效的影响效应。采用 3× 2被试间设计 ,自变量为超文本结构 (层次、混合、网状 )和时间应激(应激组和对照组 ) ,因变量为答题速度和迷路指数。 48名大学生或研究生被试参与实验。结果发现 ,时间应激对超文本搜索绩效有重要影响。更具体地说 ,时间应激对网状结构超文本搜索绩效的影响尤为明显。因此 ,在需对用户浏览时间进行控制的情况下 ,最好不要采用网状结构的超文本设计。另外 ,超文本结构对超文本搜索绩效的影响效应再次得到证实。The influence of time stress on search performances for information with different hypertext structures was examined in this study.The 3×2 experiment design with 8 repeats was employed.The independent variables were hypertext structure(hierarchical,mixed,and network)and time stress(stress group and control group).The dependent variables were the mean search speed and missing.Forty-eight undergraduate and graduate students participated in the study.It was found that time stress had significant influence on search performances of hypertext information.Particularly,the search performance was impaired in the case of network hypertext under time stress.Therefore,the network hypertext should be avoided in time-limited situation.
