认知负荷视角下数字图书馆用户从众信息使用行为研究

Research on User Herd Information Use Behavior in the Context of Digital Library from the Perspective of Cognitive Load

[目的/意义]认知负荷是从众行为产生的重要影响因素,从认知负荷视角出发,对数字图书馆环境下从众信息使用行为及其前置动因进行考察,有助于深入理解用户信息使用活动中的从众行为,为数字图书馆用户服务优化提供参考。[方法/过程]首先,结合从众行为相关研究和认知负荷理论构建研究模型;然后采用问卷调查法,搜集308份有效样本数据;最后利用偏最小二乘结构方程模型方法对研究模型进行验证。[结果/结论]研究发现,模仿他人、导航结构和流体验显著正向影响从众信息使用意愿,任务复杂度对从众信息使用意愿的影响被流体验所抑制;流体验和任务复杂度显著正向影响模仿他人,导航结构对模仿他人的影响不显著;模仿他人分别部分中介任务复杂度、导航结构、流体验对从众信息使用意愿的作用。基于上述研究结果,从提供商和用户层面出发,为数字图书馆的长远发展、用户服务优化及信息使用行为引导提供若干建议。

[Purpose/Significance]Cognitive load is an important factor for herd behavior.This paper explores herd information use behavior and its antecedents in the context of digital library from the perspective of cognitive load,which could help understand users’herd behavior of information user behavior better,and provide reference for the optimization of user services in the digital library.[Method/Process]Firstly,this paper constructed the research model based on herd behavior research and cognitive load theory.Then,it collected data using questionnaire survey and got 308 valid data.Finally,the partial-least-squares structural equation model was used to verify the research model.[Result/Conclusion]The findings show that imitating others,navigation structure and flow experience positively affect herd information use intention,while the effect of task complexity on herd information use intention is overpowered by flow experience.Flow experience and task complexity have a significant positive effect on imitating others,while navigation structure has no significant effect on imitating others.Imitating others partially mediates the effects of task complexity,navigation structure,and flow experience on herd information use intention.Based on the above results,this paper provides some suggestions for the long-term development of the digital library,user service optimization,and information use behavior guidance from the providers and users.
