Shifts of criteria or neural timing? The assumptions underlying timing perception studies

► Perceived event timing is often investigated with TOJs and SJs to determine a PSS. ► Fitting such data to aid interpretation implies countenancing a psychological model. ► Detection theoretic models of SJs and TOJs leave the meaning of the PSS ambiguous. ► We illustrate these issues by replicating audiovisual temporal recalibration. ► Occam's razor favours changed criteria for judging synchrony over changed latencies.
