探索式学术信息搜索行为研究——感知示能性的调节效应

An Empirical Study on Exploratory Search Behavior of Academic Information——The Moderating Effect of Perceived Affordance

[目的/意义]探索式学术信息搜索是科研工作者科学研究过程中重要一环。结合有限理性理论,探究用户对信息复杂性刺激的应对,进而构建学术信息搜索行为理论模型。[方法/过程]借鉴前人研究成果初步提炼影响因素,采用线上专家学者访谈方式确定研究采用的具体影响因素,并基于外部刺激(S)—机体认知(O)—行为反应(R)3个层次,通过二阶结构方程模型进行分析。[结果/结论]研究显示信息维度和方法维度刺激显著增强期望确认,而期望确认促进学术信息搜索行为,但是感知示能性会显著减弱外部刺激对期望确认的影响。结果证明学术搜索行为不是简单的需求-搜索行为,而是受到认知期望与认知能力影响的有限理性行为。

[Purpose/Significance]The exploratory search for academic information is an important part of the scientific research process of scientists.From the bounded rational theory to explore the response of users to the stimuli of information complexity,and then constructs theoretical models of academic information search behavior.[Method/Process]The paper used the results of previous scientists research to initially refine the influencing factors,and used online interviews with experts and scholars to determine the specific influencing factors used in the research and based on external stimulus(S )-organism cognition(O )-behavioral response(R),analyzed by a second-order structural equation model.[Result/Conclusion]Studies showed that information dimension stimulation and method dimension stimulation significantly enhanced organism expectation confirmation,while expectation confirmation promoted the academic information search behavior,but perceived affordance performance significantly reduced the influence of external stimulation on expectation confirmation.The results proved that academic search behavior was not a simple demand-search behavior but a bounded rational behavior influenced by cognitive expectations and cognitive ability.
