§ 1. It is well-known that in the special theory of relativity the simultaneity of distant events is frame-relative: two events simultaneous according to the standard Einstein criterion as applied in one inertial frame are not simultaneous according to the same criterion applied in a relatively moving inertial frame. Not so well known is whether, given a fixed inertial frame, there is a fact of...

Information about an event takes diVerent amounts of time to be processed depending on which sensory system the event activates. However, despite the variations in processing time for lights and sounds, the point of subjective simultaneity (PSS) for brieXy presented audio/ visual stimuli is usually close to true simultaneity. Here we conWrm that the simultaneity constancy mechanism that achieve...

Attended stimuli are perceived as occurring earlier than unattended stimuli. This phenomenon of prior entry is usually identified by a shift in the point of subjective simultaneity (PSS) in temporal order judgements (TOJs). According to its traditional psychophysical interpretation, the PSS coincides with the perception of simultaneity. This assumption is, however, questionable. Technically, th...

The 'temporal rule' of multisensory integration (MI) proposes that unisensory stimuli, and the neuronal responses they evoke, must fall within a window of integration. Ecological validity demands that MI should occur only for physically simultaneous events (which may give rise to non-simultaneous neural activations), and spurious neural response simultaneities unrelated to environmental multise...

Multisensory interactions are well established to convey an array of perceptual and behavioral benefits. One of the key features of multisensory interactions is the temporal structure of the stimuli combined. In an effort to better characterize how temporal factors influence multisensory interactions across the lifespan, we examined audiovisual simultaneity judgment and the degree of rapid reca...
