- The Swedish reading span test (Rönnberg, Lyxell, Arlinger, & Kinnefors, 1989) is often used to assess working memory capacity (WMC) in the field of cognitive hearing science. The test has proven useful as a predictor of speech recognition in noise in adverse conditions. It has been used in a wide range of experimental studies and has been translated to several languages. The purpose of this paper was to provide reference data for the Swedish reading span test (Rönnberg et al., 1989) in a large sample of adults with hearing impairment aged 50-89 years that are representative of patients seeking rehabilitation at audiological clinics. Data from finished and ongoing projects were collated and reanalyzed for this purpose. The original full version and a shortened version of the test were compared, in terms of percentage correct. In addition, performance on the full version was compared across two different age-cohorts, 50-69 year olds and 70-89 year olds. Frequency distributions and percentile scores are reported, as well as relations with demographic variables, and speech recognition in noise. Results showed that reading span performance was related to age, but not sex, with lower scores in older participants. Pure tone hearing thresholds accounted for a small but significant amount of the variance such that higher reading span scores were related to better hearing. The frequency distributions of scores did not differ across the two versions of the test, but the long version seemed to be more sensitive to age. Performance in both versions was significantly correlated with speech recognition in noise. Regression analyses however showed that reading span explained additional variance in speech in noise recognition, after the effects of age and pure tone hearing thresholds were accounted for, only in the 50-69 year olds. These findings are discussed in relation to age-related differences in the ability to recruit cognitive resources in the service of speech communication.

- A Swedish Hearing In Noise Test (HINT), consisting of everyday sentences to be used in an adaptive procedure to estimate the speech recognition thresholds in noise and quiet, has been developed. The material consists of 250 sentences, with a length of five to nine syllables, normalized for naturalness, difficulty and reliability. The sentences were recorded with a female speaker. From the sentences, 25 phonemically balanced lists were created. All lists fluctuate less than 1 dB of the overall mean. The standard deviation of the test-retest difference is 0.94 dB when testing with one list, and decreases to 0.68 dB and 0.56 dB for two and three lists, respectively. The average speech recognition thresholds in noise for the Swedish sentences were -3.0 dB signal/noise ratio (SD = 1.1 dB). The present study has resulted in a well-defined and internationally comparable set of sentences, which can be used in Swedish audiological rehabilitation and research to measure speech recognition in noise and quiet. © 2006 British Society of Audiology, International Society of Audiology, and Nordic Audiological Society.

- OBJECTIVE: To study the effect of chronologic age on central auditory functions using dichotic speech tests and to study whether and how the age effect in dichotic listening is related to cognitive ability.DESIGN: Dichotic speech tests and cognitive tests were performed on 30 bilaterally hearing-impaired subjects, with a pure-tone average better than 50 dB HL. They were between 42 and 84 yr of age and were divided into an older and a younger group comprising 15 subjects each. The dichotic test material were digits, low-redundancy sentences and consonant-vowel syllables. The subjects reported stimuli heard in both ears (free report) or in one ear (directed report to left or right ear). The cognitive test battery comprised tests focusing on short-term memory, verbal information-processing speed and phonologic processing.RESULTS: A decreased overall performance in all dichotic speech tests was observed in the older group. In the syllable test the older subjects showed poorer results when focusing on the stimuli heard in the left ear, as compared with when focusing on stimuli heard in the right ear, whereas the younger group showed almost equal results for left- and right ear-focusing conditions. An age effect was also seen in reaction times recorded in the cognitive tests and in the scores of the reading span test. These cognitive parameters correlate with the results of the dichotic test when focusing to the left, but not when focusing to the right in the directed report condition. In the free report condition the overall performance showed a high correlation with cognitive test parameters.CONCLUSIONS: Effects of chronologic age in dichotic speech tests in the elderly have been verified. The degree of effect is dependent on test material, way of reporting and focusing condition. The different listening tasks in dichotic tests put different demands on cognitive ability shown by a varying degree of correlations between cognitive function and dichotic test parameters. Also, the results indicate a strong connection between age-related cognitive decline in the elderly and problems to perceive stimuli presented to the left ear.
