对综合性文献数据库大学生用户心智模型的影响因素和效应进行探索。研究采用实验法收集数据,采用独立样本t检验、单因素方差分析和多元线性回归法分析数据。61名大学生参与了此项试验。研究表明:①用户心智模型影响因素方面:网龄和认知风格是造成差异的两个重要因素。就网龄而言,高网龄组的心智模型平均得分高于低网龄组,体现在内容认知、用户负面情感和用户正面情感3个维度。就认知风格而言,场独立组用户的心智模型得分显著高于场依存组,体现在用户界面功能认知维度。年龄的不同对用户心智模型及其各个维度均未产生差异。此外,虽然性别、学科、年级、使用频率、学习风格在用户心智模型整体上没有差异,但却在相应的维度上有差异。②用户心智模型效应方面:用户心智模型在用户特征与用户检索绩效之间存在中介效应。就网龄变量而言,用户心智模型起着完全中介效应;就用户认知风格变量而言,用户心智模型可能起着部分中介效应(仍有待今后进一步验证)。本研究可为大学生个性化信息素养培训提供参考。

The mental model plays an important role in users' interaction with academic database. This paper explores the influences factors and effects of undergraduate students' mental models in comprehensive academic databases. An experiment is conducted to collect data, which is analyzed with independent-sample test, one-way analysis of variance and multiple linear regressions to analyze data. Sixty-one undergraduate students participate in this study. ①on the aspect of influences factors of user mental model, it finds that: network age and cognitive style are two important factors for the individual difference; in terms of network age factor, the mental model score of high network age group is higher than low one; in perspectives of content cognitive, user positive and negative emotions dimensions; in terms of cognitive style factor, the mental model score of field independence group is higher than field dependence one in perspective of interface capabilities cognitive of user; the difference of age does not affect user mental model and each dimension; the factors of gender, major, grade, use frequency and learning style have not significant effect on user mental model but have some difference in corresponding dimensions. ②On the effect of user mental model aspect, it finds that: user mental model has a mediation effect between user character and search performance; in terms of cognitive style factor, user mental model may play a partial mediation effect, but remains to be further proved and discussed; in terms of network age factor, user mental model has a full mediation effect. This study has implications in the personalized information literacy training of undergraduate students.
