Abstract:
AbstractAudiovisual speech perception has been considered to operate independent of sound location, since the McGurk effect (altered auditory speech perception caused by conflicting visual speech) has been shown to be unaffected by whether speech sounds are presented in the same or different location as a talking face. Here we show that sound location effects arise with manipulation of spatial attention. Sounds were presented from loudspeakers in five locations: the centre (location of the talking face) and 45°/90° to the left/right. Auditory spatial attention was focused on a location by pres

Abstract:
We report the unexpected finding that slowing video playback decreases perception of the McGurk effect. This reduction is counter-intuitive because the illusion depends on visual speech influencing the perception of auditory speech, and slowing speech should increase the amount of visual information available to observers. We recorded perceptual data from 110 subjects viewing audiovisual syllables (either McGurk or congruent control stimuli) played back at one of three rates: the rate used by the talker during recording (the natural rate), a slow rate (50% of natural), or a fast rate (200% of

Abstract:
Language is essentially multi-modal in its sensory origin, the daily conversation depending heavily on the audio-visual (AV) information. Although the perception of spoken language is primarily dominated by audition, the perception of facial expression, particularly that of the mouth, helps us comprehend speech. The McGurk effect is a striking phenomenon where the perceived phoneme is affected by the simultaneous observation of lip movement, and probably reflects the underlying AV integration process. The elucidation of the principles involved in this unique perceptual anomaly poses an interes

Abstract:
Since its discovery 40 years ago, the McGurk illusion has been usually cited as a prototypical paradigmatic case of multisensory binding in humans, and has been extensively used in speech perception studies as a proxy measure for audiovisual integration mechanisms. Despite the well-established practice of using the McGurk illusion as a tool for studying the mechanisms underlying audiovisual speech integration, the magnitude of the illusion varies enormously across studies. Furthermore, the processing of McGurk stimuli differs from congruent audiovisual processing at both phenomenological and n

Abstract:
In 1976 Harry McGurk and I published a paper in Nature, 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 eff

Abstract:
The human brain can quickly adapt to changes in the environment. One example is phonetic recalibration: a speech sound is interpreted differently depending on the visual speech and this interpretation persists in the absence of visual information. Here, we examined the mechanisms of phonetic recalibration. Participants categorized the auditory syllables /aba/ and /ada/, which were sometimes preceded by the so-called McGurk stimuli (in which an /aba/ sound, due to visual /aga/ input, is often perceived as ‘ada’). We found that only one trial of exposure to the McGurk illusion was sufficient to

Abstract:
Speech is perceived with both the ears and the eyes. Adding congruent visual speech improves the perception of a faint auditory speech stimulus, whereas adding incongruent visual speech can alter the perception of the utterance. The latter phenomenon is the case of the McGurk illusion, where an auditory stimulus such as e.g. “ba” dubbed onto a visual stimulus such as “ga” produces the illusion of hearing “da”. Bayesian models of multisensory perception suggest that both the enhancement and the illusion case can be described as a two-step process of binding (informed by prior knowledge) and fus

The McGurk effect is a robust illusion phenomenon in the perception of speech; however, there is little research on its demonstration in nonverbal domains. Thus, we tested for the McGurk effect in the context of self-recognition. We presented a group of people with schizophrenia and a control group of people without mental illnesses, with 2 videos accompanied by a soundtrack featuring different identity information. The first video had a matched face and voice; the other featured conflicting face–voice information. The participants judged if the voice in the video was their own or someone else

Abstract Speech perception ability and structural neuroimaging were investigated in two cases of bilateral opercular syndrome. Due to bilateral ablation of the motor control center for the lower face and surrounds, these rare cases provide an opportunity to evaluate the necessity of cortical motor representations for speech perception, a cornerstone of some neurocomputational theories of language processing. Speech perception, including audiovisual integration (i.e., the McGurk effect), was mostly unaffected in these cases, although verbal short-term memory impairment hindered performance on s

Abstract:
Persons with hearing loss use visual information from articulation to improve their speech perception. Even persons with normal hearing utilise visual information, especially when the stimulus-to-noise ratio is poor. A dramatic demonstration of the role of vision in speech perception is the audiovisual fusion called the ‘McGurk effect’. When the auditory syllable /pa/ is presented in synchrony with the face articulating the syllable /ka/, the subject usually perceives /ta/ or /ka/. The illusory perception is clearly auditory in nature. We recently studied the audiovisual fusion (acoustical /p/

Based on research on the “McGurk Effect” (McGurk & McDonald, 1976) in speech perception, some researchers (e.g. Liberman & Mattingly, 1985) have argued that humans uniquely interpret auditory and visual (motor) speech signals as a single intended audiovisual articulatory gesture, and that such multisensory integration is innate and specific to language.

The McGurk effect is an audiovisual speech illusion in which tacit lip-reading of a spoken syllable influences perception of a synchronized, but discrepant, auditory syllable. The effect works on speakers of different native languages and on prelinguistic infants. The effect is also robust to various image manipulations and to observers’ conscious awareness of the stimulus composition. For these reasons, the effect has become one of the preeminent demonstrations of multisensory perception.

Abstract:
What is the correct procedure for determining the contents of perception? Philosophers tackling this question increasingly rely on empirically oriented procedures. This chapter argues that this strategy constitutes an improvement over the armchair methodology of phenomenal contrast arguments, but that there is a respect in which current empirical procedures remain limited: they are unimodal in nature, wrongly treating the senses as isolatable. The chapter thus has two aims: first, to motivate a reorientation of the admissible contents debate into a multimodal framework. The second is to explore whether experimental studies of multimodal perception support a so-called Liberal account of perception’s admissible contents. The chapter concludes that the McGurk effect and the ventriloquist effect are both explicable without the postulation of high-level content, but that at least one multimodal experimental paradigm may necessitate such content: the rubber hand illusion. One upshot is that Conservatives who claim that the Liberal view intolerably broadens the scope of perceptual illusions, particularly from the perspective of perceptual psychology, should pursue other arguments against that view.

Abstract:
Crossmodal perceptual illusions such as ventriloquism, the McGurk effect, the rubber hand, and the sound-induced flash demonstrate that one sense can causally impact perceptual processing and experience that is associated with another sense. This chapter argues that such causal interactions between senses are not merely accidental. Interactions between senses are part of typical perceptual functioning. Unlike synesthesia, they reveal principled perceptual strategies for dealing with noisy, fallible sensory stimulation from multiple sources. Recalibrations resolve conflicts between senses and weight in deference to the more reliable modality. Coordination between senses thus improves the coherence and the reliability of human perceptual capacities. Therefore, some perceptual processes of the sort relevant to empirical psychology are multisensory.

The McGurk effect is a psycholinguistic phenomenon where an illusion is made by dubbing an auditory element of one sound on a visual element of another sound, which leads to hearing a third sound. The phenomenon demonstrates how the perception of speech does not depend on audio inputs only. Rather, it shows how seeing the shape of the mouth while producing a certain sound can influence what we hear. Thus, it proves the interaction of both vision and auditory parameters in understanding language. In addition, what is known as “lexicality – the property of a word being real or not” influences sp
