- Purpose: To examine the relation between speech recognition and cognitive skills in bimodal cochlear implant (CI) and hearing aid users.Method: Seventeen bimodal CI users (28-74 years) were recruited to the study. Speech recognition tests were carried out in quiet and in noise. The cognitive tests employed included the Reading Span Test and the Trail Making Test (Daneman & Carpenter, 1980; Reitan, 1958, 1992), measuring working memory capacity and processing speed and executive functioning, respectively. Data were analyzed using paired-sample t tests, Pearson correlations, and partial correlations controlling for age.Results: The results indicate that performance on some cognitive tests predicts speech recognition and that bimodal listening generates a significant improvement in speech in quiet compared to unilateral CI listening. However, the current results also suggest that bimodal listening requires different cognitive skills than does unimodal CI listening. This is likely to relate to the relative difficulty of having to integrate 2 different signals and then map the integrated signal to representations stored in the long-term memory.Conclusions: Even though participants obtained speech recognition benefit from bimodal listening, the results suggest that processing bimodal stimuli involves different cognitive skills than does unimodal conditions in quiet. Thus, clinically, it is important to consider this when assessing treatment outcomes.

- When children start formal education, they are expected to be able to express complex thoughts. However, in order to do so, they need to be able to use both complex grammatical structures and a variety of words. One group that is at risk of having a delay in terms of their expressive language ability is children with cochlear implants (CI). In this study, we evaluated whether children with CI perform comparably to children with typical hearing (TH) on a standard expressive spoken grammar and a standard expressive spoken vocabulary task when the groups were matched on non-verbal intelligence and working memory capacity. It was found that the children with CI in this study performed more poorly on a standard expressive spoken vocabulary task but not on a standard expressive spoken grammar task when compared to the children with TH. Differences in terms of expressive spoken vocabulary do not seem to be explained by differences in cognitive ability. In addition, the variation in terms of expressive spoken language ability was larger in the children with CI compared to the children with TH. This might be explained by additional confounding factors, like the time of language deprivation or by a greater influence of cognitive differences for the acquisition of spoken language for children with CI.

Reasons for Language : Language and Analogical Reasoning Ability in Children with Cochlear Implants and Children with Typical Hearing
- 2020

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The usage-based model of language acquisition assumes that language is learned by its usage. General cognitive processes, especially analogical reasoning ability, are assumed to lead to the understanding of words and grammatical structures. It has been argued that the time of language or auditory deprivation children with cochlear implants (CIs) often experience early in life, might affect both their language and their cognitive abilities. Children with CIs have disadvantages in terms of language acquisition as they start receiving language input later than peers with typical hearing (TH), and the perceptual quality of the input is reduced. However, they might have additional difficulties in language acquisition if their analogical reasoning ability is negatively influenced by the language or auditory deprivation early in life. The results found in this thesis show that the language delays often seen in children with CIs are not explained by differences in analogical reasoning ability. Results indicate that analogical reasoning ability has a limited influence on language acquisition for the tested age-group. However, language abilities affect the performance on analogical reasoning tasks which are either verbal or can be supported by verbal strategies. This needs to be taken into consideration when comparing analogical reasoning ability of children with CI sand children with TH. In addition, the results from this thesis indicate that the structure of the mental lexicon is associated with the communication skills of children with CIs. The structure of the mental lexicon is most likely influenced by the amount of language input a child receives. The main implication of the results is that emphasis should be put on reducing the duration of language deprivation and to improve the quality of the language input for children with CIs.

- ObjectiveUsing data from the n200-study, we aimed to investigate the relationship between behavioural (the Swedish HINT and Hagerman speech-in-noise tests) and self-report (Speech, Spatial and Qualities of Hearing Questionnaire (SSQ)) measures of listening under adverse conditions.DesignThe Swedish HINT was masked with a speech-shaped noise (SSN), the Hagerman was masked with a SSN and a four-talker babble, and the subscales from the SSQ were used as a self-report measure. The HINT and Hagerman were administered through an experimental hearing aid.Study sampleThis study included 191 hearing aid users with hearing loss (mean PTA4 = 37.6, SD = 10.8) and 195 normally hearing adults (mean PTA4 = 10.0, SD = 6.0).ResultsThe present study found correlations between behavioural measures of speech-in-noise and self-report scores of the SSQ in normally hearing individuals, but not in hearing aid users.ConclusionThe present study may help identify relationships between clinically used behavioural measures, and a self-report measure of speech recognition. The results from the present study suggest that use of a self-report measure as a complement to behavioural speech in noise tests might help to further our understanding of how self-report, and behavioural results can be generalised to everyday functioning.
