“…Their greater difficulty to synchronize to the beat of musical excerpts compared to the performance with the metronome is in line with results found in adults (Sowiński & Dalla Bella 2013;Dalla Bella et al 2017a) and NH children populations (Puyjarinet et al 2017). Specifically for children with HL, this difficulty could be partly due to the greater demands in terms of auditory scene analysis which heavily involves spectral analysis to elaborate and select objects in a complex auditory environment (Oxenham 2008;Shinn-Cunningham et al 2017).…”

Children with hearing loss (HL), in spite of early cochlear implantation, often struggle considerably with language acquisition. Previous research has shown a benefit of rhythmic training on linguistic skills in children with HL, suggesting that improving rhythmic capacities could help attenuating language difficulties. However, little is known about general rhythmic skills of children with HL and how they relate to speech perception. The aim of this study is twofold: (1) to assess the abilities of children with HL in different rhythmic sensorimotor synchronization tasks compared to a normal-hearing control group and (2) to investigate a possible relation between sensorimotor synchronization abilities and speech perception abilities in children with HL.Design: A battery of sensorimotor synchronization tests with stimuli of varying acoustic and temporal complexity was used: a metronome, different musical excerpts, and complex rhythmic patterns. Synchronization abilities were assessed in 32 children (aged from 5 to 10 years) with a severe to profound HL mainly fitted with one or two cochlear implants (n = 28) or with hearing aids (n = 4). Working memory and sentence repetition abilities were also assessed. Performance was compared to an age-matched control group of 24 children with normal hearing. The comparison took into account variability in working memory capacities. For children with HL only, we computed linear regressions on speech, sensorimotor synchronization, and working memory abilities, including device-related variables such as onset of device use, type of device, and duration of use.Results: Compared to the normal-hearing group, children with HL performed poorly in all sensorimotor synchronization tasks, but the effect size was greater for complex as compared to simple stimuli. Group differences in working memory did not explain this result. Linear regression analysis revealed that working memory, synchronization to complex rhythms performances, age, and duration of device use predicted the number of correct syllables produced in a sentence repetition task. Conclusion:Despite early cochlear implantation or hearing aid use, hearing impairment affects the quality of temporal processing of acoustic stimuli in congenitally deaf children. This deficit seems to be more severe with stimuli of increasing rhythmic complexity highlighting a difficulty in structuring sounds according to a temporal hierarchy.

“…Theoretically, both segregation and grouping are important processes for cocktail-447 party listening as they lend support to the formation and selection of perceptual objects in 448 the auditory scene (for a recent review, see Shinn- Cunningham et al, 2017). However, GPR 449 and VTL might contribute differently to these processes.…”

“…Binding stimulus features from a common source is not a unique problem across sensory modalities-within a modality, independently encoded perceptual features (e.g., color, shape and orientation in vision; pitch, timbre, and spatial cues in audition) must also be combined to form a single perceptual object. These perceptual objects are the "units" on which attention operates, both in vision (Desimone and Duncan 1995) and audition (Shinn-Cunningham et al 2017). Given that there is a central limitation in the amount of information the brain can process, attention helps to determine what object(s) the brain analyzes in order to make sense of a complex scene.…”

Visual cues help listeners to follow conversation in a complex acoustic environment. Many audiovisual research studies focus on how sensory cues are combined to optimize perception, either in terms of minimizing the uncertainty in the sensory estimate or maximizing intelligibility, particularly in speech understanding. From an auditory perception perspective, a fundamental question that has not been fully addressed is how visual information aids the ability to select and focus on one auditory object in the presence of competing sounds in a busy auditory scene. In this chapter, audiovisual integration is presented from an object-based attention viewpoint. In particular, it is argued that a stricter delineation of the concepts of multisensory integration versus binding would facilitate a deeper understanding of the nature of how information is combined across senses. Furthermore, using an object-based theoretical framework to distinguish binding as a distinct form of multisensory integration generates testable hypotheses with behavioral predictions that can account for different aspects of multisensory interactions. In this chapter, classic multisensory illusion paradigms are revisited and discussed in the context of multisensory binding. The chapter also describes multisensory experiments that focus on addressing how visual stimuli help listeners parse complex auditory scenes. Finally, it concludes with a discussion of the potential mechanisms by which audiovisual processing might resolve competition between concurrent sounds in order to solve the cocktail party problem.
