Abstract: | Synchrony perception for audio-visual stimulus pairs is typically studied by using temporal order judgment (TOJ) or synchrony judgment (SJ) tasks. Research has shown that estimates of the point of subjective simultaneity (PSS) obtained using these two methods do not necessarily correspond. Here, we investigate the hypothesis that the PSS estimate obtained in a TOJ task is shifted in the direction of the most sensitive part of the synchrony judgment curve, as obtained in an SJ task. The results confirm that criterion shifts in the TOJ task move the PSS toward regions of the audio-visual temporal interval continuum where discriminations are most sensitive. |
