“…Therefore, they cannot be ascribed to his lesion in Broca's area specifically. The variability seen across participants in these studies is not specific to aphasic patients but is also seen across studies of healthy subjects (Colin and Radeau, 2003 ). It is likely to be due, not only to variation across participants but also to variation across stimuli (Magnotti and Beauchamp, 2014 ).…”

Lesions to Broca's area cause aphasia characterized by a severe impairment of the ability to speak, with comparatively intact speech perception. However, some studies have found effects on speech perception under adverse listening conditions, indicating that Broca's area is also involved in speech perception. While these studies have focused on auditory speech perception other studies have shown that Broca's area is activated by visual speech perception. Furthermore, one preliminary report found that a patient with Broca's aphasia did not experience the McGurk illusion suggesting that an intact Broca's area is necessary for audiovisual integration of speech. Here we describe a patient with Broca's aphasia who experienced the McGurk illusion. This indicates that an intact Broca's area is not necessary for audiovisual integration of speech. The McGurk illusions this patient experienced were atypical, which could be due to Broca's area having a more subtle role in audiovisual integration of speech. The McGurk illusions of a control subject with Wernicke's aphasia were, however, also atypical. This indicates that the atypical McGurk illusions were due to deficits in speech processing that are not specific to Broca's aphasia.

“…Two different kinds of illusions have been observed: fusions and combinations. While visual presentation of a syllable containing a velar consonant like /gi/ together with an auditory syllable containing a bilabial consonant like /bi/ is likely to elicit a fused response /di/, the reverse presentation will normally give rise to a combination such as /bgi/ (see Massaro, 1987;Hardison, 1996;Colin and Radeau, 2003 for reviews on the McGurk effect). The effect is mandatory and irrepressive, even when the subject has full knowledge of the actual stimuli (Summerfield and McGrath, 1984;Rosenblum and Saldaña, 1996).…”

“…In the redundant condition, several modalities access simultaneously the same object properties and then converge to perceive it [12]. The redundancy enhances learning economy, facilitates a unified view of the world, and sometimes guarantees a degree of sensory compensation [13][14][15]. In the conflicting condition, the sensory modalities receive simultaneously incongruent properties about the same object.…”

Abstract:In the framework of the design process of a multimodal 3D simulation environment to support architects' acoustic tasks, we wanted to gain a better understanding of how architects are able to discriminate the sounds using audio and/or visual inputs. This study explores how 2D pictures of rooms do support or impede the auditory evaluation of a space (specifically reverberation). The paper describes an experiment evaluating participants rankings of perceived acoustic reverberation when presented with congruent (coherent) or non-congruent (conflicting) evocative pictures of architectural spaces. We found that the congruent pictures had a positive impact on task performance while the noncongruent pictures had no significant effect. Moreover the effect of the expertise (professional background) of participants was investigated. We found differences between architects and non-architects in the way they performed the task, and they processed reverberation assessments. Taken together, the findings of this study contribute to the question of usefulness of expensive multimodal 3D simulation environment.
