Article
Temporal synchrony between visual and auditory stimuli plays an important role in audiovisual integration. Audiovisual temporal synchrony is recalibrated by the most-recent timing of audiovisual stimuli. My previous study has shown that this recalibration happens when there is compensation for neural processing speed differences based on spatial fr...

Audio-visual integration relies on temporal synchrony between visual and auditory inputs. However, differences in traveling and transmitting speeds between visual and auditory stimuli exist; therefore, audio-visual synchrony perception exhibits flexible functions. The processing speed of visual stimuli affects the perception of audio-visual synchro...
Article
In research studies on how people perceive simultaneously presented audiovisual information, researchers have often shown that the number of visual flashes participants perceive on a computer screen can be altered by varying the number of accompanying auditory, visual, or combined audiovisual cues or inducers. In the present study, we examined the...

Audiovisual integration relies on temporal synchrony between visual and auditory stimuli. The brain rapidly adapts to audiovisual asynchronous events by shifting the timing of subjective synchrony in the direction of the leading modality of the most recent event, a process called rapid temporal recalibration. This phenomenon is the flexible functio...

The word order that is easiest to understand in a language generally coincides with the word order most frequently used in that language. In Kaqchikel, however, there is a discrepancy between the two: the syntactically basic VOS incurs the least cognitive load, whereas SVO is most frequently employed. This suggests that processing load is primarily...

Multisensory integration is affected by various types of information coming from different sensory stimuli. It has been suggested that emotional information also influences the multisensory integration process. The perceptual phenomena induced by audio-visual integration are modulated by emotional signals through changing individuals’ emotional sta...

Previous studies have not yet investigated sufficiently the relationship between visual processing and negative emotional valence intensity, which is the degree of a dimensional component included in emotional information. In Experiment 1, participants performed a visual search task with three valence levels: neutral (control) and high- and low-int...
Article

Emotional processing that occurs partially in advance of perceptual processing is known as pre-perceptual emotional processing. The facilitation of sensory processing due to pre-perceptual emotional processing can be observed in visual search and attentional blink tasks. However, previous event-related potential studies have suggested that pre-perc...

Temporal consistency between visual and auditory presentations is necessary for integration of visual and auditory information. Subjective simultaneity perception is more important than the synchrony of physical inputs for temporal consistency. Our previous studies have shown that audiovisual integration is difficult even if the visual and auditory...

Audio-visual integration interacts with attentional mechanisms. Additionally, salient auditory stimuli automatically draw attention to an audio-visual event, while spatial attention can modulate audio-visual integration. Attention induced by auditory inputs (sound-driven attention) facilitates visual perception. Similarly, visual attention improves...
Article
When a brief single flash is presented simultaneously with two brief beeps, the number of presented flashes is often perceived as two. This phenomenon is referred to as the fission illusion. Several effects related to the fission illusion have been investigated using both psychophysical and neurophysiological methods. The present study examined the...

Numerosity judgment of visual objects includes various perceptual and cognitive processes. Previous studies have indicated that there are two processes in numerosity judgmentsa subitizing process for up to three or four items and a counting process for over three or four items. These numerosity judgment processes are reported to reflect different t...

Even though auditory stimuli do not directly convey information related to visual stimuli, they often improve visual detection and identification performance. Auditory stimuli often alter visual perception depending on the reliability of the sensory input, with visual and auditory information reciprocally compensating for ambiguity in the other sen...
Article
Auditory stimuli often facilitate visual perception. Audiovisual integration requires spatial and/or temporal proximity between visual and auditory stimuli; additionally, sensory processing speed affects the audiovisual integration process. In the present study we examined the relationship between processing speed and the auditory facilitation effe...

This study examined cortical activity associated with the processing of visual feedback following self-generated finger movement. We used near-infrared spectroscopy (NIRS) to measure cortical activity in the lateral prefrontal cortex. Participants were required to click on the left or the right button of a computer mouse. This action was immediatel...
Article
Several studies have examined the effects of auditory stimuli on visual perception. In studies of cross-modal correspondences, auditory pitch has been shown to modulate visual motion perception. In particular, low-reliability visual motion stimuli tend to be affected by metaphorically or physically congruent or incongruent sounds. In the present st...
Article
The fission illusion is induced by multisensory (audio-visual) integration. In the present study, we assume that perceptual efficiency affects the fission illusion's rate because this illusion occurs in a short temporal range through the integration of visual and auditory information. The present study examined the effect of perceptual efficiency o...

The effect of audiovisual interactions on size perception has yet to be examined, despite its fundamental importance in daily life. Previous studies have reported that object length can be estimated solely on the basis of the sounds produced when an object is dropped. Moreover, it has been shown that people typically and easily perceive the corresp...

We examined the effect of loading a weight on the perception of the end position of the limb. The participants haptically perceived where the end of their limb was located while they swung the limb or statically held it. The results showed that the loading of a weight influenced participants' perception only when they swung the limb; when the weigh...

A fission illusion (also named a double—flash illusion) is a famous phenomenon of audio-visual interaction, in which a single brief flash is perceived as two flashes when presented simultaneously with two brief beeps (Shames, Kamitani, & Shimojo, 2000; 2002). The fission illusion has been investigated using relatively simple visual stimuli like sin...

Auditory stimuli are known to alter visual perception. However, the effects of such stimuli on velocity perception have not yet been examined. A well-known velocity illusion related to object size is described by Brown’s law. We can easily match object size with sound intensity. Therefore, this study examined the potential modification of velocity...

Most of the numerous studies on velocity illusion have focused on the visual velocity illusion, with few studies focusing on the auditory velocity illusion. As a step toward filling this lacuna, the present study concentrated on the auditory velocity illusion through the use of pendulum motion. We attempted to replicate the visual velocity illusion...
