EEG Spectral Analysis of the Cognitive Load Generated by Users Reading Multi-Modal Re-sources of Digital Public Cultural Services——A Case on National Public Culture Cloud
[Purpose/significance]This study focuses on the current situation of multi-modal resource integration in digital public cul-tural service platforms.Taking cognitive load as the starting point,this paper analyzes the cognitive characteristics of users'digital reading in the context of digital public cultural services,and puts forward suggestions to optimize the construction of multi-modal re-sources for digital public cultural services.[Method/process]This paper uses the EEG controlled experimental method to obtain EEG data when users read multi-modal resources of digital public cultural services.Conduct spectrum analysis and statistics on EEG data to clarify the cognitive differences of users reading multi-modal resources.[Result/conclusion]Visual activation of composite multi-modal resources(text-pictures)induces higher cognitive load,working memory load and attention investment;audiovisual activation of composite multimodal resources(text-pictures-video)induces lower Cognitive load,working memory load,and attentional engage-ment.When building multi-modal resources for digital public cultural services,when building multi-modal resources for digital pub-lic cultural services,auditory activation,multivariate audiovisual integration and visually activated multimodal resources should be en-riched to achieve refined construction of resources.[Innovation/limitation]This study explores the feasibility of directly applying neu-rophysiological data to information behavior research,subdivides multi-modal resource types,and puts forward feasible suggestions for the construction of multi-modal resources for digital public cultural services.The research deficiency lies in the use of small-scale controlled experiments for research.Taking the National Public Culture Cloud Platform as an example,the conclusions may have limi-tations.
