"Explaining"or"Leaving Blank":A Study on the Cognitive Effects of Different Syntactic-Graphical Content Structures in Data Journalism
This research evaluates the cognitive impacts of five text-graphic structures within data journalism-graph-dominated,text-dominated,overlapping,dialogue,and negotiation-on encoding,storage,and retrieval processes,through an experiment with 76 participants.Anchored in the LC4MP theoretical framework,the study uncovers significant variance in cognitive processing based on the content structure.Specifically,text-dominated structures excel in fostering short-term cognitive performance,whereas overlapping and text-dominated arrangements are more effective for enhancing long-term memory and improving overall information quality.Notably,graph-dominated structures are particularly efficient at aiding the recall of central information,thus facilitating the deeper assimilation of news content into knowledge.Despite technological advancements,this study reaffirms the critical role of text in data journalism and suggests that news producers can optimize information dissemination by strategically selecting and combining content structures to match intended cognitive outcomes.
