“…However, in ISTS noise there was no significant difference between performance in AV and A-only conditions. The better performance in A-only modality compared to AV has been reported in dual task paradigm studies as well (Fraser et al, 2010;Gosselin & Gagné, 2011). This may be because loading on executive functions makes it difficult to prioritize task-related processing in the presence of low-priority stimuli (Lavie, 2005).…”

“…However, this comes at the cost of reduced cognitive resources, which is demonstrated as higher listening effort or fatigue (Edward, 2007;Picou, Ricketts & Hornsby, 2011). Recently, listening effort has been defined in cognitive terms, where it has been defined as the cognitive resources that are consumed for speech recognition (Picou, et al 2011;Fraser, Gagné, Alepins & Dubois, 2010). From this definition it can be assumed that listening effort will be more pronounced when CSC for the individuals is reduced.…”

“…Fraser et al (2010) compared sentence recognition in noise in the A-only and AV modalities of presentation with a concurrent tactile pattern recognition task. When the A-only and the AV stimuli were presented at same SNR ratio, performance was better in the AV modality of presentation while performance was equal in the concurrent tactile task.…”

Exploring Cognitive Spare Capacity : Executive Processing of Degraded Speech

Cognitive resources, specifically working memory capacity are used for listening to speech, especially in noise. Cognitive resources are limited, and if listeners allocate a greater share of these resources to recovering the input signal in noise, fewer resources are available for interpreting and encoding its linguistic content. Although the importance of CSC for individual success in communicative situations has been acknowledged, this concept has not hitherto been explored experimentally. In this thesis, a CSC test (CSCT) was developed and administered to young adults with normal hearing and older adults with age-related hearing loss. CSCT required executive processing of speech at different memory loads with and without visual cues in different noise conditions. A free recall task using the same material was administered for comparison purposes and a battery of cognitive tests was administered to understand the relation between CSC and established cognitive concepts. The aims of the thesis were to investigate how CSC is influenced by 1) different executive demands and memory loads; 2) background noise; 3) visual cues; 4) aging and concomitant hearing loss. The results showed that 1) CSC was sensitive to memory load, and updating demands reduced CSC more than inhibition demands; 2) CSC was reduced in background noise compared to quiet; 3) visual cues enhanced CSC especially in noise; 4) CSC was reduced with ageing and concomitant hearing loss especially when visual cues were absent, memory demands were increased and background noise was speech-like. The main finding of this thesis was that visual cues enhanced CSC for older individuals with hearing loss, specifically in adverse listening conditions. This demonstrates the importance of audiovisual testing in audiological assessment. Further, specific cognitive resources depleted during listening in noise were at least partially compensated by other cognitive functions. This thesis is the first step towards a theoretical understanding of CSC and in future, tests of CSC may play a crucial role in planning rehabilitation of persons with hearing loss.

Objective: To explore areas of functioning, disability and environmental factors of adults with hearing loss (HL) by using the ICF classification as a tool to determine and document each element. Design: A qualitative study applying mainly focus-group methodology was applied). Conclusions: The present study illustrates the complexity and comprehensiveness of aspects involved in functioning and disability of adults with HL. The findings highlight the necessity of using a multidimensional tool, such as the ICF, where both internal and external aspects are valued and considered in the analysis.

“…The results from the present experiments revealed an advantage for auditory-visual speech in noise as compared to other experimental stimuli, in both behavioral measures of task performance and the associated neural correlates. Comparisons were made at each SNR level, however, and when speech was presented in a noisy environment, accurate auditory-visual speech perception may have required less effort than is required with auditory-only speech (Fraser, Gagné, Alepins, & Dubois, 2010).…”

Speech perception, especially in noise, may be maximized if the perceiver observes the naturally occurring visual-plus-auditory cues inherent in the production of spoken language. Evidence is conflicting, however, about which aspects of visual information mediate enhanced speech perception in noise. For this reason, we investigated the relative contributions of audibility and the type of visual cue in three experiments in young adults with normal hearing and vision. Relative to static visual cues, access to the talker's phonetic gestures in speech production, especially in noise, was associated with (a) faster response times and sensitivity for speech understanding in noise, and (b) shorter latencies and reduced amplitudes of auditory N1 eventrelated potentials. Dynamic chewing facial motion also decreased the N1 latency, but only meaningful linguistic motions reduced the N1 amplitude. The hypothesis that auditory-visual facilitation is distinct to properties of natural, dynamic speech gestures was partially supported. Keywords Evoked potentials . Multisensory processing . Speech perceptionEveryone experiences difficulty understanding speech at some point, especially in noisy environments or in the presence of a hearing loss. The natural setting for speech communication is in a face-to-face environment where people can both hear the speech and see the face of the talker. Considerable evidence has shown that performance on speech perception tasks improves when information from both auditory and visual modalities is available
