The proportions of visual-first responses (V-first) for each exposure lag (−100 ms sound-first, 100 ms light-first) for each combination of location of exposure sound (central, lateral) and location of the test sound (central, lateral)

Schematic illustration of the experimental conditions. In the exposure phase, the subject was exposed to a sound–light pair with 100 ms temporal offset (either sound-first or light first). During exposure, sounds were either presented from central (a, c) or lateral location (b, d). In the test phase, sound–light pairs were presented with a particular SOA ranging between −240 and 240 ms, with negative values indicating that the sound was presented first. Sounds of the test-stimulus pair either came from central (a, b) or lateral location (c, d )
