Arousal Mechanism of Visual Discrete Emotions on Public Involvement in Health Crisis Public Opinion Videos:An Empirical Study Based on VAR Model
[Purpose/significance]Health crisis events may have a sustained impact on the audience.Clarifying the emotional os-cillation patterns and involvement mechanisms of the public in public opinion videos can help the industry and academia grasp and pre-dict the dynamic development trends of the public opinion field.[Method/process]This paper takes the Bilibili video social platform as an example,constructs a VAR time series model using the theory of emotional contagion,and deeply analyzes the facial discrete emo-tional oscillation patterns and public dynamic involvement mechanisms of publishers in 420 public opinion videos.[Result/conclusion]Different types of facial emotions have a differentiated impact on public involvement,with aversion being an important trigger in health crises,triggering the fastest and most rapid climax of public involvement among all emotions.Overall,the strongest impact on public in-volvement is on negative high arousal emotions,followed by negative low arousal emotions,and the weakest impact is on positive and neutral emotions.
