Selective Attention Modulates the Direction of Audio-Visual Temporal Recalibration - Figure 1

A) Schematic representation of a fragment of the adaptation phase in Experiments 1 and 2. The sequence was composed by a flash, a tone and a flash (in the example, RED appears leading the tone and GREEN lagging the tone). The tone was displayed at the perceptual temporal middle between the flashes (SOA adjusted individually and fixed during the adaptation phase). The inset depicts an example of one standard flash (95%) and the corresponding two possible oddball target stimuli (5%) presented during adaptation and re-adaptation phase in Experiment 1 and 2. B) Example of a test trial in Experiments 1 and 2. The fixation cross changed from white to red and after a 1000 ms pause, the test trial (duration = 1000 ms) started. After 500 ms one GREY flash was presented in the centre of the screen and one tone was displayed at one of nine asynchronies ranging from −353 to +353 ms with respect to the flash. Participants responded whether the GREY flash and the tone were simultaneous or not. The fixation turned back to grey and a new re-adaptation sequence started. (The white background surrounding the black pedestal was not included in the figure).
