Representative video frames from four ASMR categories: Mic, Proximal, Eating, and Nature. The first three categories featured an on-screen performer engaging in ASMR trigger behaviors. Mic videos included scenes involving direct contact with microphones using fingers, ear picks, balloons, nails, or towels. Proximal videos depicted hand movements and object manipulations occurring in close proximity to the camera, evoking a sense of personal attention. Eating videos presented close-up sounds of consuming various foods. Nature videos served as a control condition and consisted of non-social audiovisual environments. Each video lasted 30 s, and five distinct videos were prepared for each category. Colored borders around video frames indicate individual video conditions and correspond to time-series lines in Fig. 2.
