摘要

Digital marketing analytics capture behavioral outcomes—clicks, dwell time, conversions—but offer limited insight into how engagement unfolds during interaction. This research develops a multimodal framework that infers engagement-related behavioral configurations from synchronized gesture, gaze, facial, vocal, and linguistic signals, across two overlapping samples of video-mediated sessions (N = 34 and N = 40). Stress-related activation is robustly and negatively associated with attentional stabilization, a result that withstands collinearity diagnostics, bootstrap resampling, and alternative model specifications. Its positive association with intentional engagement is also observed at the session level, but is substantially weaker once features shared across indicators are removed and does not hold at finer temporal resolution—underscoring that not all engagement associations are equally robust to measurement overlap. Multimodal indicators add explanatory power beyond attention-based metrics within the framework, though this should be read as internal incremental contribution pending external validation. This research offers a transparent behavioral inference framework and a methodological template for testing the robustness and temporal structure of such indicators, and identifies external validation as the next step toward establishing them as measures of engagement.
