Do the Different Sensory Areas Within the Cat Anterior Ectosylvian Sulcal Cortex Represent a Network Multisensory Hub?
Source:Page Count 31Current theory supports that the numerous functional areas of the cerebral cortex are organized and function as a network. Using connectional databases and computational approaches, the cerebral network has been demonstrated to exhibit a hierarchical structure composed of areas, clusters and, ultimately, hubs. Hubs are highly connected, higher-order regions that also facilitate communication between different sensory modalities. One computationally identified network hub is the visual area of the Anterior Ectosylvian Sulcal cortex (AESc) of the cat. The Anterior Ectosylvian Visual area (AEV) is but one ...

Audiovisual Integration Varies With Target and Environment Richness in Immersive Virtual Reality (Advance Article)
Source:Page Count 25We are continually bombarded by information arriving to each of our senses; however, the brain seems to effortlessly integrate this separate information into a unified percept. Although multisensory integration has been researched extensively using simple computer tasks and stimuli, much less is known about how multisensory integration functions in real-world contexts. Additionally, several recent studies have demonstrated that multisensory integration varies tremendously across naturalistic stimuli. Virtual reality can be used to study multisensory integration in realistic settings because it combines ...

Intact Dynamic Visual Capture in People With One Eye (Advance Article)
Source:Page Count 14Observing motion in one modality can influence the perceived direction of motion in a second modality (dynamic capture). For example observing a square moving in depth can influence the perception of a sound to increase in loudness. The current study investigates whether people who have lost one eye are susceptible to audiovisual dynamic capture in the depth plane similar to binocular and eye-patched viewing control participants. Partial deprivation of the visual system from the loss of one eye early in life results in changes in the remaining intact senses such as hearing. Linearly expanding or contrac...

Cybersickness: a Multisensory Integration Perspective
Source:Page Count 30In the past decade, there has been a rapid advance in Virtual Reality (VR) technology. Key to the user ’s VR experience are multimodal interactions involving all senses. The human brain must integrate real-time vision, hearing, vestibular and proprioceptive inputs to produce the compelling and captivating feeling of immersion in a VR environment. A serious problem with VR is that users may develop symptoms similar to motion sickness, a malady calledcybersickness. At present the underlying cause of cybersickness is not yet fully understood. Cybersickness may be due to a discrepancy between the sensory ...

Still no Evidence for Sustained Effects of Multisensory Integration of Duration (Advance Article)
Source:Page Count 22In studies on temporal order perception, immediate as well as sustained effects of multisensory integration have been demonstrated repeatedly. Regarding duration perception, the corresponding literature reports clear immediate effects of multisensory integration, but evidence on sustained effects of multisensory duration integration is scarce. In fact, a single study [Heron, J.et al. (2013). A neural hierarchy for illusions of time: Duration adaptation precedes multisensory integration,J. Vis.13, 1 –12.] investigated adaptation to multisensory conflicting intervals, and found no sustained effects ...

Effects of Auditory Patterns on Judged Displacements of an Occluded Moving Object (Advance Article)
Source:Page Count 21Using displays in which a moving disk disappeared behind an occluder, we examined whether an accompanying auditory rhythm influenced the perceived displacement of the disk during occlusion. We manipulated a baseline rhythm, comprising a relatively fast alternation of equal sound and pause durations. We had two different manipulations to create auditory sequences with a slower rhythm: either the pause durations or the sound durations were increased. In the trial, a disk moved at a constant speed, and at a certain point moved behind an occluder during which an auditory rhythm was played. Participants were...

Segregation and Integration of Cortical Information Processing Underlying Cross-Modal Perception
Source:Volume 31, Issue 5, pp 481 - 500Visual cues from the speaker ’s face influence the perception of speech. An example of this influence is demonstrated by the McGurk-effect where illusory (cross-modal) sounds are perceived following presentation of incongruent audio–visual (AV) stimuli. Previous studies report the engagement of specific cortical modules tha t are spatially distributed during cross-modal perception. However, the limits of the underlying representational space and the cortical network mechanisms remain unclear. In this combined psychophysical and electroencephalography (EEG) study, the participants ...

Amending Ongoing Upper-Limb Reaches: Visual and Proprioceptive Contributions?
Source:Volume 31, Issue 5, pp 455 - 480In order to maximize the precise completion of voluntary actions, humans can theoretically utilize both visual and proprioceptive information to plan and amend ongoing limb trajectories. Although vision has been thought to be a more dominant sensory modality, research has shown that sensory feedback may be processed as a function of its relevance and reliability. As well, theoretical models of voluntary action have suggested that both vision and proprioception can be used to prepare online trajectory amendments. However, empirical evidence regarding the use of proprioception for onlin...

Grasping and Pointing — Visual Conflict and Interference
Source:Volume 31, Issue 5, pp 439 - 454There have been many debates of the two-visual-systems (whatvs. how or perceptionvs. action) hypothesis that was proposed by Goodale and his colleagues. Many researchers have provided a variety of evidence for or against the hypothesis. For instance, a study performed by Agliotiet al. offered good evidence for the two-visual-systems theory using the Ebbinghaus illusion, but some researchers who used other visual illusions failed to find consistent results. Therefore, we used a perceptual task of conflict or interference to test this hypothesis. If the conflict or interference in perce...

[i] is Lighter and More Greenish Than [o]: Intrinsic Association Between Vowel Sounds and Colors
Source:Volume 31, Issue 5, pp 419 - 437It has recently been reported in the synesthesia literature that graphemes sharing the same phonetic feature tend to induce similar synesthetic colors. In the present study, we investigated whether phonetic properties are associated with colors in a specific manner among the general population, even when other visual and linguistic features of graphemes are removed. To test this hypothesis, we presented vowel sounds synthesized by systematically manipulating the position of the tongue body ’s center. Participants were asked to choose a color after hearing each sound. Results from th...

Reciprocal Interference Between Audition and Touch in the Perception of Duration
Source:Volume 31, Issue 5, pp 351 - 371Audition and touch interact with one another and share a number of similarities; however, little is known about their interplay in the perception of temporal duration. The present study intended to investigate whether the temporal duration of an irrelevant auditory or tactile stimulus could modulate the perceived duration of a target stimulus presented in the other modality (i.e., tactile or auditory) adopting both a between-participants (Experiment 1) and a within-participants (Experiment 2) experimental design. In a two-alternative forced-choice task, participants decided which o...

The Rubber Hand Illusion in Healthy Younger and Older Adults
Source:Page Count 19Percepts about our body ’s position in space and about body ownership are informed by multisensory feedback from visual, proprioceptive, and tactile inputs. The Rubber Hand Illusion (RHI) is a multisensory illusion that is induced when an observer sees a rubber hand being stroked while they feel their own, spatially disp laced, and obstructed hand being stroked. When temporally synchronous, the visual–tactile interactions can create the illusion that the rubber hand belongs to the observer and that the observer’s real hand is shifted in position towards the rubber hand. Importantly, little is unde...

Distinct Autistic Traits Are Differentially Associated With the Width of the Multisensory Temporal Binding Window
Source:Page Count 14Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication and interaction, and restricted interests and behavior patterns. These characteristics are considered as a continuous distribution in the general population. People with ASD show atypical temporal processing in multisensory integration. Regarding the flash –beep illusion, which refers to how a single flash can be illusorily perceived as multiple flashes when multiple auditory beeps are concurrently presented, some studies reported that people with ASD have a wider temporal binding window a...

Transfer of Audio-Visual Temporal Training to Temporal and Spatial Audio-Visual Tasks
Source:Page Count 23Temporal and spatial characteristics of sensory inputs are fundamental to multisensory integration because they provide probabilistic information as to whether or not multiple sensory inputs belong to the same event. The multisensory temporal binding window defines the time range within which two stimuli of different sensory modalities are merged into one percept and has been shown to depend on training. The aim of the present study was to evaluate the role of the training procedure for improving multisensory temporal discrimination and to test for a possible transfer of training to other multisensory t...
