"Although linguistic styles shape social media engagement, the cognitive-affective pathways through which warmth- versus competence-oriented styles interact with sharer types (human/virtual influencers) to influence tourist sharing lack empirical verification in video-based contexts. Through three experimental studies with cross-cultural tourist samples, we demonstrate: (1) Person perception asymmetry: Human influencers\u2019 warmth-oriented styles and virtual influencers\u2019 competence-oriented styles trigger synergistic effects on sharing intention; (2) Serial mediation mechanism: Processing fluency (cognitive) initiates a causal chain culminating in psychological richness (affective)\u2014providing initial evidence for this affective driver in sharing behaviors; (3) Contextual constraint: Temporal perception moderates this relationship, where queue management interventions (reducing perceived duration) boost sharing. We propose: a) Matched linguistic strategies: Warmth-oriented communication for human vs. competence-oriented for virtual influencers; b) Psychological richness priming through experiential narratives paired with temporal perception optimization. Theoretical contributions include: (i) Psychological richness as a personality-relevant affective mediator beyond satisfaction, (ii) Temporal perception as a socio-cognitive boundary condition, advancing person-agent interaction theory in digital environments."

The rich factors and number of genes involved in each pathway derived from a comparison of gene expression in TBvsTL, OTBvsOTL, TBvsOTB and TL2vsOTL2. TBvsOTB stands for tea buds versus oil tea buds, TBvsTL for tea buds versus tea leaves, TLvsOTL for tea leaves versus oil tea leaves and OTBvsOTL for oil tea buds versus leaves. (XLSX 16Â kb)
