“…This direction of bias in PSS has been reported repeatedly for passive audiotactile TOJ (Zampini et al, 2005; Nishi et al, 2014; Hao et al, 2015), suggesting that the tactile event should be presented slightly earlier than the auditory one for it to be perceived simultaneously with the auditory event. We observed no significant differences of PSSs between the conditions.…”

“…Previous studies have examined the effects of voluntary movements on temporal perception of sensory events without causal relationship between voluntary movements and sensory events (Frissen et al, 2012; Nishi et al, 2014; Hao et al, 2015). In contrast, the present study examined whether voluntary movements improve perceptual sensitivity to temporal disparity between mutltisensory events when those events are virtually caused by the voluntary movements.…”

“…They compared the effects of voluntary and involuntary movements on multisensory temporal sensitivity, but the findings are not consistent even among the studies from the same laboratory. Although no significant differences in JNDs for the temporal disparity of auditory-somatosensory events between the voluntary and involuntary movement conditions have been reported (Frissen et al, 2012; Hao et al, 2015), improvement (Nishi et al, 2014) and even deterioration (Hao et al, 2016) of the JNDs has also been observed in the voluntary movement condition compared to passive and involuntary ones. The reason for this inconsistency between the findings of the previous studies is unclear.…”

“…More recent studies have tried to further assess the effects of voluntary movements on multisensory temporal perception by introducing an involuntary movement condition in which the participants’ arm or finger is moved passively by a device (Frissen et al, 2012; Nishi et al, 2014; Hao et al, 2015, 2016). They compared the effects of voluntary and involuntary movements on multisensory temporal sensitivity, but the findings are not consistent even among the studies from the same laboratory.…”

When we actively interact with the environment, it is crucial that we perceive a precise temporal relationship between our own actions and sensory effects to guide our body movements. Thus, we hypothesized that voluntary movements improve perceptual sensitivity to the temporal disparity between auditory and movement-related somatosensory events compared to when they are delivered passively to sensory receptors. In the voluntary condition, participants voluntarily tapped a button, and a noise burst was presented at various onset asynchronies relative to the button press. The participants made either “sound-first” or “touch-first” responses. We found that the performance of temporal order judgment (TOJ) in the voluntary condition (as indexed by the just noticeable difference (JND)) was significantly better (M = 42.5 ms ± 3.8 SEM) than that when their finger was passively stimulated (passive condition: M = 66.8 ms ± 6.3 SEM). We further examined whether the performance improvement with voluntary action can be attributed to the prediction of the timing of the stimulation from sensory cues (sensory-based prediction), kinesthetic cues contained in voluntary action, and/or to the prediction of stimulation timing from the efference copy of the motor command (motor-based prediction). When three noise bursts were presented before the target burst with regular intervals (predictable condition) and when the participant’s finger was moved passively to press the button (involuntary condition), the TOJ performance was not improved from that in the passive condition. These results suggest that the improvement in sensitivity to temporal disparity between somatosensory and auditory events caused by the voluntary action cannot be attributed to sensory-based prediction and kinesthetic cues. Rather, the prediction from the efference copy of the motor command would be crucial for improving the temporal sensitivity.

“…In a TOJ task, the participants are required to judge the temporal order of the two stimuli. These tasks have revealed that people tend to perceive different modal stimuli as occurring simultaneously when they are presented with a short lag ( Slutsky and Recanzone, 2001 ; Lewald and Guski, 2003 ; Kayser et al, 2008 ; Shi et al, 2008 ; Nishi et al, 2014 ). More specifically, the PSS differs from the point of physical simultaneity.…”

The simultaneous perception of auditory–tactile stimuli in voluntary movement

The simultaneous perception of multimodal information in the environment during voluntary movement is very important for effective reactions to the environment. Previous studies have found that voluntary movement affects the simultaneous perception of auditory and tactile stimuli. However, the results of these experiments are not completely consistent, and the differences may be attributable to methodological differences in the previous studies. In this study, we investigated the effect of voluntary movement on the simultaneous perception of auditory and tactile stimuli using a temporal order judgment task with voluntary movement, involuntary movement, and no movement. To eliminate the potential effect of stimulus predictability and the effect of spatial information associated with large-scale movement in the previous studies, we randomized the interval between the start of movement and the first stimulus, and used small-scale movement. As a result, the point of subjective simultaneity (PSS) during voluntary movement shifted from the tactile stimulus being first during involuntary movement or no movement to the auditory stimulus being first. The just noticeable difference (JND), an indicator of temporal resolution, did not differ across the three conditions. These results indicate that voluntary movement itself affects the PSS in auditory–tactile simultaneous perception, but it does not influence the JND. In the discussion of these results, we suggest that simultaneous perception may be affected by the efference copy.
