Reversal of Subjective Temporal Order due to Arm Crossing

How does the brain order successive events? We have recently shown that crossing the arms caused many subjects to misreport (that is, invert) the temporal order of two stimuli delivered in succession, one to each hand, at moderately short intervals (< 300 ms), though at longer intervals (> 1 s) they generally responded correctly. In contrast, when the arms were uncrossed, the subjects could respond correctly at intervals as short as 70 ms. We conclude that it is not until the spatial locations of the hands are taken into account that the cutaneous signals from the respective hands are ordered in time.
