Steady-State EEG and Psychophysical Measures of Multisensory Integration to Cross-Modally Synchronous and Asynchronous Acoustic and Vibrotactile Amplitude Modulation Rate
In this study we investigated whether cross-modal congruence of AM rate reveals both psychophysical and EEG evidence of enhanced multisensory integration. To achieve this, EEG SSR and psychophysical sensitivity to simultaneous acoustic and/or vibrotactile AM stimuli were measured at cross-modally congruent and incongruent AM rates. While the results provided no evidence of superadditive multisensory SSR activity or psychophysical sensitivity, the complex pattern of results did reveal a consistent correspondence between SSR activity and psychophysical sensitivity to AM stimulation. This indicates that entrained EEG activity...

Hearing Lips and Seeing Voices: the Origins and Development of the ‘McGurk Effect’ and Reflections on Audio–Visual Speech Perception Over the Last 40 Years
In 1976 Harry McGurk and I published a paper inNature, entitled ‘Hearing Lips and Seeing Voices’. The paper described a new audio–visual illusion we had discovered that showed the perception of auditorily presented speech could be influenced by the simultaneous presentation of incongruent visual speech. This hitherto unknown effect has since had a profound impact on audiovisual speech perception research. The phenomenon has come to be known as the ‘McGurk effect’, and the original paper has been cited in excess of 4800 times. In this paper I describe the background to the discovery of the effect, the rationale fo...

Inter-Individual Differences in Vicarious Tactile Perception: a View Across the Lifespan in Typical and Atypical Populations
Source:Page Count 24Touch is our most interpersonal sense, and so it stands to reason that we represent not only our own bodily experiences, but also those felt by others. This review will summarise brain and behavioural research on vicarious tactile perception (mirror touch). Specifically, we will focus on vicarious touch across the lifespan in typical and atypical groups, and will identify the knowledge gaps that are in urgent need of filling by examining what is known about how individuals differ within and between typical and atypical groups.

Vection Latency Is Reduced by Bone-Conducted Vibration and Noisy Galvanic Vestibular Stimulation
Source:Volume 30, Issue 1, pp 65 - 90Studies of the illusory sense of self-motion elicited by a moving visual surround ( ‘vection’) have revealed key insights about how sensory information is integrated. Vection usually occurs after a delay of several seconds following visual motion onset, whereas self-motion in the natural environment is perceived immediately. It has been suggested that this latency relates to th e sensory mismatch between visual and vestibular signals at motion onset. Here, we tested three techniques with the potential to reduce sensory mismatch in order to shorten vection onset latency: noisy galvan...

Muscle Vibration-Induced Illusions: Review of Contributing Factors, Taxonomy of Illusions and User’s Guide
Source:Volume 30, Issue 1, pp 25 - 63Limb muscle vibration creates an illusory limb movement in the direction corresponding to lengthening of the vibrated muscle. Neck muscle vibration results in illusory motion of visual and auditory stimuli. Attributed to the activation of muscle spindles, these and related effects are of great interest as a tool in research on proprioception, for rehabilitation of sensorimotor function and for multisensory immersive virtual environments. However, these illusions are not easy to elicit in a consistent manner. We review factors that influence them, propose their classification in a scheme...

Multisensory Decisions: the Test of a Race Model, Its Logic, and Power
Source:Volume 30, Issue 1, pp 1 - 24The use of separate multisensory signals is often beneficial. A prominent example is the speed-up of responses to two redundant signals relative to the components, which is known as the redundant signals effect (RSE). A convenient explanation for the effect is statistical facilitation, which is inherent in the basic architecture of race models (Raab, 1962,Trans. N. Y. Acad. Sci. 24, 574 –590). However, this class of models has been largely rejected in multisensory research, which we think results from an ambiguity in definitions and misinterpretations of the influential race model te...

Domestic Dogs and Human Infants Look More at Happy and Angry Faces Than Sad Faces
We presented 52 domestic dogs and 24 seven-month-old human infants with two different human emotional facial expressions of the same gender simultaneously, while listening to a human voice expressing an emotion that matched one of them. Consistent with most matching studies, neither dogs nor infants looked longer at the matching emotional stimuli, yet dogs and humans demonstrated an identical pattern of looking less at sad faces when paired with happy or angry faces (irrespective of the vocal stimulus), with no preference for happyversus angry faces. Discussion focuses on why dogs and infants might have an aversion to sad ...

Shape Discrimination Using the Tongue: Implications for a Visual-to-Tactile Sensory Substitution Device (Advance Article)
Source:Page Count 26Sensory substitution devices have the potential to provide individuals with visual impairments with more information about their environments, which may help them recognize objects and achieve more independence in their daily lives. However, many of these devices may require extensive training and might be limited in the amount of information that they can convey. We tested the effectiveness and assessed some of the limitations of the BrainPort device, which provides stimulation through a 20 × 20 electrode grid array on the tongue. Across five experiments, including one with blind individuals, we fou...
