Dataset and analysis code accompanying the poster Battle for Attention: How Style and Narration Control Gaze in Dual-Screen Viewing, presented at the Society for Cognitive Studies of the Moving Image (SCSMI) Annual Conference, Amsterdam, 2026. Study overview Sixty-four participants (CP: n = 33, fixed TikTok playlist; EV: n = 31, free TikTok browsing; age M = 20.7 ± 3.4 years; 53% female) watched TV clips (Emily in Paris, Reacher, Slow TV; ~36 min of stimuli) while simultaneously using a tablet with TikTok short-form video. Gaze was recorded continuously with Pupil Labs Invisible mobile eye-tracking glasses. Two areas of interest were defined: the TV screen and the tablet. Tablet audio was muted throughout; the TV was the sole audio source. The study examined which formal properties of TV content attract gaze back to the screen during dual-screen viewing. Three findings emerged: (1) salient auditory events increased the probability of a tablet-to-TV gaze return from 17.2% to 24.2% (OR = 1.57, p = .003); (2) expressive close-up faces in Emily in Paris more than doubled the return probability relative to neutral faces (31.3% vs 13.3%; OR = 2.33, p < .001); (3) shot type predicted attentional balance — POV shots showed the highest net Tab→TV pull (+2.18 switches/min), with Reaction shots second (+1.02). Repository contents Raw gaze data are not shared (participant privacy). The repository contains: csv files — aggregated summary statistics: switch probability tables, descriptive switch rates by shot type, and shot-level face annotation lookup. R scripts — three R scripts reproducing all poster results from raw data: SNAP_E2_sound.R (salient sound → gaze switching), SNAP_E2_expressive.R (expressive faces → gaze switching), SNAP_E2_shots.R (shot type ↔ switch rates). figures — the three poster figures at 300 DPI (PNG).
