Abstract [en]

Purpose Seeing the talker's face improves speech understanding in noise, possibly releasing resources for cognitive processing. We investigated whether it improves free recall of spoken two-digit numbers.

Method Twenty younger adults with normal hearing and 24 older adults with hearing loss listened to and subsequently recalled lists of 13 two-digit numbers, with alternating male and female talkers. Lists were presented in quiet as well as in stationary and speech-like noise at a signal-to-noise ratio giving approximately 90% intelligibility. Amplification compensated for loss of audibility.

Results Seeing the talker's face improved free recall performance for the younger but not the older group. Poorer performance in background noise was contingent on individual differences in working memory capacity. The effect of seeing the talker's face did not differ in quiet and noise.

Conclusions We have argued that the absence of an effect of seeing the talker's face for older adults with hearing loss may be due to modulation of audiovisual integration mechanisms caused by an interaction between task demands and participant characteristics. In particular, we suggest that executive task demands and interindividual executive skills may play a key role in determining the benefit of seeing the talker's face during a speech-based cognitive task

Abstract [en]

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.

Abstract [sv]

Kognitiva resurser, speciellt arbetsminneskapacitet, förbrukas när vi lyssnar på tal, framförallt i bakgrundsbrus. De kognitiva resurserna är begränsade och ju större del som används till att rekonstruera en inkommande signal, desto färre finns fortsatt tillgängliga för att koda in och tolka dess språkliga innehåll. Trots att betydelsen av kognitiv reservkapacitet för framgångrik kommunikation är erkänd har kognitiv reservkapacitet hittills inte blivit undersökt experimentellt. I detta avhandlingsarbete utvecklades CSCT som ett test av kognitiv reservkapacitet. CSCT administrerades till unga vuxna med normal hörsel och äldre individer med åldersrelaterad hörselnedsättning. CSCT kräver exekutiv bearbetning av talat språk under olika minnesbelastningar, med och utan tillgång till visuell information och med och utan bakgrundsbrus. En fri återgivningsuppgift, baserad på samma material som i CSCT, administrerades för att kunna göra jämförelser. Slutligen administrerades ett kognitivt testbatteri för att förstå relationen mellan kognitiv reservkapacitet och andra kognitiva funktioner. Avhandlingens syfte var att undersöka hur kognitiv reservkapacitet påverkas av 1) olika krav på de exekutiva förmågorna och olika grad av minnesbelastning; 2) bakgrundsbrus; 3) tillgång till visuell information; 4) åldrande och åldersrelaterad hörselnedsättning. Resultaten visade att kognitiv reservkapacitet 1) var känsligt för minnesbelastning och reducerades mer av uppdaterings- än inhibitionskrav; 2) reducerades av bakgrundsbrus; 3) ökade med tillgång till visuell information, framförallt i bakgrundsbrus; 4) var reducerad hos äldre med åldersrelaterad hörselnedsättning, speciellt när visuell information saknades, minnesbelastningen ökades och bakgrundsbruset bestod av talspråk. Huvudfyndet var att visuell information frigjorde kognitiv reservkapacitet hos äldre individer med nedsatt hörsel, speciellt när lyssningssituationen var ogynnsam. Detta visar på betydelsen av audiovisuell testning vid audiologisk bedömning. Resultaten visade vidare att när specifika kognitiva resurser förbrukades under ogynnsamma lyssningsförhållanden kunde andra kognitiva funktioner kompensera för detta. Denna avhandling utgör det första steget mot en teoretisk förståelse av kognitiv reservkapacitet. På sikt kan utvärdering av kognitiv reservkapacitet spela en avgörande roll för planering av rehabilitering i samband med hörselnedsättning.
