Parsing of information from the world into objects and events occurs in both the visual and auditory modalities. It has been suggested that visual and auditory scene perception involve similar principles of perceptual organization. This study investigated cross-modal scene perception by determining whether an auditory stimulus could facilitate visual object segregation. Specifically, we examine...

OBJECTIVE Patients with auditory neuropathy spectrum disorder (ANSD) exhibit altered neural synchrony in response to auditory stimuli. Cochlear implantation (CI) is thought to improve neural synchrony in response to auditory stimuli and improve speech perception relative to conventional hearing amplification (HA). STUDY DESIGN Retrospective review. SETTING Tertiary otologic practice. SUBJ...

Whether human speech perception depends on a biologically based link between production and perception or whether it is best characterised as a series of acoustic, phonetic, and semantic transformations has remained an unresolved issue. We addressed this question via the use of objective brain research methods combined with advanced stimulus production methodology. We removed the contribution o...

  Background :Older adults with cerebrovascular accident (CVA) show evidence of auditory and speech perception problems. In present study, it was examined whether these problems are due to impairments of concurrent auditory segregation procedure which is the basic level of auditory scene analysis and auditory organization in auditory scenes with competing sounds.   Methods : Concurrent auditory...

Speech perception involves multiple input modalities. Research has indicated that perceivers establish cross-modal associations between auditory and visuospatial events to aid perception. Such intermodal relations can be particularly beneficial for speech development and learning, where infants and non-native perceivers need additional resources to acquire and process new sounds. This study exa...

Audiovisual speech perception is likely based on the association between auditory and visual information into stable audiovisual maps. Conflicting audiovisual inputs generate perceptual illusions such as the McGurk effect. Audiovisual mismatch effects could be either driven by the detection of violations in the standard audiovisual statistics or via the sensorimotor reconstruction of the distal...

OBJECTIVES To determine whether adults with persistent developmental stuttering (PDS) have auditory perceptual deficits. METHODS The authors compared the mismatch negativity (MMN) event-related brain potential elicited to simple tone (frequency and duration) and phonetic contrasts in a sample of PDS subjects with that recorded in a sample of paired fluent control subjects. RESULTS Subjects ...

The current study examined older and younger adults’ perception of auditory and auditory-visual Lombard speech. A staircase procedure was used to estimate the SNR required for participants to achieve 50% correct auditory identification of Quiet and Lombard speech (CVC and VCV stimuli). Stimuli were then presented in auditory only (AO), visual only (VO) and auditory visual (AV) conditions in a s...

Visible speech enhances the intelligibility of auditory speech when listening conditions are poor [1], and can modify the perception of otherwise perfectly audible utterances [2]. This audiovisual perception is our most natural form of communication and one of our most common multisensory phenomena. However, where and in what form the visual and auditory representations interact is still not co...
