Abstract [en]

Purpose: The study aimed to assess the relationship between 1) speech-recognition-in-noise, mask type, working memory capacity (WMC), inhibitory control, and 2) self-rated listening effort, speech material, and mask type, in older adults with and without hearing-impairment. It was of special interest to assess the relationship between WMC, inhibitory control, and speech-recognition-in-noise when informational maskers masked target speech.

Method: A mixed design was used. A group (N= 24) of older (mean age = 69.7 years) HI individuals, and a group of age-normal hearing adults (mean age = 59.3 years, SD = 6.5) participated in the study. The participants were presented with auditory tests in a sound attenuated room and the cognitive tests in a quiet office. The participants were asked to rate listening effort after being presented with energetic and informational background maskers in two different speech materials used in this study (i.e., Hearing in Noise Test and the Hagerman Test). Linear-Mixed Effects models were set up to assess the effect of the two different speech materials, energetic and informational maskers, hearing ability, WMC, inhibitory control, and self-rated listening effort.

Results: Results showed that WMC and inhibitory control was of importance for speech-recognition-in-noise, even when controlling for PTA4 (pure tone average 4) hearing thresholds and age, when the maskers were informational. Concerning listening effort, on the other hand,  the results suggest that hearing ability, but not cognitive abilities, is important for self-rated listening effort in speech-recognition-in-noise.

Conclusion: Speech-in-noise recognition is more dependent on WMC for older adults in informational maskers than in energetic maskers. Hearing ability is a stronger predictor than cognition for self-rated listening effort.

Abstract [en]

Objectives:

Actively following a conversation can be demanding and limited cognitive resources must be allocated to the processing of speech, retaining and encoding the perceived content, and preparing an answer. The aim of the present study was to disentangle the allocation of effort into the effort required for listening (listening effort) and the effort required for retention (memory effort) by means of pupil dilation.

Design:

Twenty-five normal-hearing German speaking participants underwent a sentence final word identification and recall test, while pupillometry was conducted. The participants task was to listen to a sentence in four-talker babble background noise and to repeat the final word afterward. At the end of a list of sentences, they were asked to recall as many of the final words as possible. Pupil dilation was recorded during different list lengths (three sentences versus six sentences) and varying memory load (recall versus no recall). Additionally, the effect of a noise reduction algorithm on performance, listening effort, and memory effort was evaluated.

Results:

We analyzed pupil dilation both before each sentence (sentence baseline) as well as the dilation in response to each sentence relative to the sentence baseline (sentence dilation). The pupillometry data indicated a steeper increase of sentence baseline under recall compared to no recall, suggesting higher memory effort due to memory processing. This increase in sentence baseline was most prominent toward the end of the longer lists, that is, during the second half of six sentences. Without a recall task, sentence baseline declined over the course of the list. Noise reduction appeared to have a significant influence on effort allocation for listening, which was reflected in generally decreased sentence dilation.

Conclusion:

Our results showed that recording pupil dilation in a speech identification and recall task provides valuable insights beyond behavioral performance. It is a suitable tool to disentangle the allocation of effort to listening versus memorizing speech.

Abstract [en]

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.

Abstract [en]

Purpose: To examine repetition of stress and tonal word accents in real words and non-words in Swedish-speaking children with developmental language disorder (DLD), and to investigate the relation of prosodic repetition to measures of language ability.

Method: A cross-sectional study was undertaken with 30 monolingual Swedish-speaking children with DLD, mean age 4;11 (years;months) and 29 age-matched controls, mean age 5;1, who repeated words and non-words with systematically varying prosody. Group differences for the repetition of prosodic features, and correlations between repetition and phonology, grammar, and vocabulary, were explored.

Result: Children with DLD performed below controls on repetition of prosodic features of words and non-words. Repetition of stress and tonal word accent was not correlated with phonological production or receptive vocabulary, but a significant correlation was found between stress repetition in words and expressive grammar.

Conclusion: Repetition of stress and tonal word accents is challenging for children with DLD acquiring Swedish as their first language, but may not be a good indicator of general language ability. Prosody should be taken into account when interpreting results from clinically used word repetition (WR) and non-word repetition (NWR) tasks.

Abstract [en]

The purpose of this study is to examine whether the neural correlates of lexical expectations could be used to predict speech in noise perception. We analyse mag-netoencephalography (MEG) data from 20 normal hearing participants, who read a set of couplets (a pair of phrases with rhyming end words) prior to the experiment. During the experiment, the participants are asked to listen to the couplets, whose intelligibility is set to 80%. However, the last word is pronounced with a delay of 1600 ms (i.e. expectation gap) and is masked at 50% of intelligibility. At the end of each couplet, the participants are asked to indicate if the last word was cor-rect, i.e. corresponding to the expected word. Given the oscillatory characteristics of neural patterns of lexical expectations during the expectation gap, can we predict the participant’s actual perception of the last word? In order to approach this re-search question, we aim to identify the correlation patterns between the instances of neural pre-activation, occurring during the interval of the expectation gap and the type of the given answer. According to the sequential design of the experiment, the expectation gap is placed 4400 ms prior to the time interval dedicated to the participant’s answer. Machine Learning approach has been chosen as the main tool for the pattern recognition.

Abstract [en]

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.

Abstract [en]

Purpose: The aim of the study was to explore aspects of learning, from a lifelong perspective, in individuals with Alstrom syndrome (AS). AS is an autosomal recessive disorder causing early blindness, progressive sensorineural hearing loss, cardiomyopathy, endocrine disorders, metabolic dysfunction, and abbreviated lifespan. Method: Eleven individuals with AS participated. The study had a qualitative explorative design, giving voice to the participants perspectives on their situation. Data were collected using semi-structured interviews, which were subjected to conventional (inductive) qualitative content analysis. Results: The analysis revealed in the participants a quest for independence and an image of themselves as capable people willing to learn, but in constant need of support to continue learning throughout their lives to be as independent as possible. Conclusion: Based on the levels of functioning, i.e. personal resources, revealed in the interviews, supervisors, caregivers, and teachers are encouraged to allow people with AS to be their own advocates, as they know best how, what, and with whom they learn, and what type of sensory material - tactile, auditory, visual, or a combination - is most helpful.Implications for RehabilitationIndividuals with AS strive for independence, and to be independent they need to continue to learn throughout their lives.Individuals with AS know best how they learn, and should be asked what modalities are the most effective for them.The tactile modality for learning will continue throughout life and should be emphasized early in the individuals education and rehabilitation.

Abstract [en]

Objective: The aim of the current study was to assess aided speech-in-noise outcomes and relate those measures to auditory sensitivity and processing, different types of cognitive processing abilities, and signal processing in hearing aids.

Material and method: Participants were 200 hearing-aid wearers, with a mean age of 60.8 years, 43% females, with average hearing thresholds in the better ear of 37.4 dB HL. Tests of auditory functions were hearing thresholds, DPOAEs, tests of fine structure processing, IHC dead regions, spectro-temporal modulation, and speech recognition in quiet (PB words). Tests of cognitive processing function were tests of phonological skills, working memory, executive functions and inference making abilities, and general cognitive tests (e.g., tests of cognitive decline and IQ). The outcome test variables were the Hagerman sentences with 50 and 80% speech recognition levels, using two different noises (stationary speech weighted noise and 4-talker babble), and three types of signal processing (linear gain, fast acting compression, and linear gain plus a non-ideal binary mask). Another sentence test included typical and atypical sentences with contextual cues that were tested both audio-visually and in an auditory mode only. Moreover, HINT and SSQ were administrated.

Analysis: Factor analyses were performed separate for the auditory, cognitive, and outcome tests.

Results: The auditory tests resulted in two factors labeled SENSITIVITY and TEMPORAL FINE STRUCTURE, the cognitive tests in one factor (COGNITION), and the outcome tests in the two factors termed NO CONTEXT and CONTEXT that relates to the level of context in the different outcome tests. When age was partialled out, COGNITION was moderately correlated with the TEMPORAL FINE STRUCTURE and NO CONTEXT factors but only weakly correlated with the CONTEXT factor. SENSITIVITY correlated weakly with TEMPORAL FINE STRUCTURE and CONTEXT, and moderately with NO CONTEXT, while TEMPORAL FINE STRUCTURE showed weak correlation with CONTEXT and moderate correlation with NO CONTEXT. CONTEXT and NO CONTEXT had a  moderate correlation. Moreover, the overall results of the Hagerman sentences showed 0.9 dB worse SNR with fast acting compression compared with linear gain and 5.5 dB better SNR with linear  gain and noise reduction compared with only linear gain.

Conclusions: For hearing aid wearers, the ability to recognize speech in noise is associated with both sensory and cognitive processing abilities when the speech materials have low internal context. These associations are less prominent when the speech material has contextual cues.

Abstract [en]

Objective: The aim of the study was to investigate the utility of an internet-based version of the trail making test (TMT) to predict performance on a speech-in-noise perception task.

Design: Data were taken from a sample of 1509 listeners aged between 18 and 91 years old. Participants completed computerized versions of the TMT and an adaptive speech-in-noise recognition test. All testing was conducted via the internet.

Results: The results indicate that better performance on both the simple and complex subtests of the TMT are associated with better speech-in-noise recognition scores. Thirty-eight percent of the participants had scores on the speech-in-noise test that indicated the presence of a hearing loss.

Conclusions: The findings suggest that the TMT may be a useful tool in the assessment, and possibly the treatment, of speech-recognition difficulties. The results indicate that the relation between speech-in-noise recognition and TMT performance relates both to the capacity of the TMT to index processing speed and to the more complex cognitive abilities also implicated in TMT performance.
