We studied 49 patients with partial epilepsy divided into lesional cases (i.e. with lesions on CT scan) and non-lesional cases (i.e. without CT scan lesions), in relation to the Wechsler Intelligence Scale subtests (Coding, Digit span), dichotic listening CV task and Central Auditory Test (SSI, PSI). The aim of this paper was to study the hemispheric prevalence in dichotic listening task with r...

Four patients who preferred monaural as compared with binaural amplification were evaluated. For these patients, audiometric data, recognition performance on a dichotic digit task, and monaural and binaural hearing aid performance using four amplification strategies (National Acoustic Laboratories-Revised, a speech in noise algorithm, multiple-microphone arrays, and frequency modulated [FM]) ar...

PURPOSE To verify the speech recognition processes in a monoaural task and in a binaural integration task with dichotic listening, and to compare them to the cognitive processing in elderly subjects pre and post hearing aid acclimatization. METHODS Participants were 60 elderly subjects of both genders, ranging in age from 61 to 85 years. They were evaluated for cognitive aspects by means of t...

Research has demonstrated that a higher level of education is associated with better performance on cognitive tests among middle-aged and elderly people. However, the effects of education on auditory processing skills have not yet been evaluated. Previous demonstrations of sensory-cognitive interactions in the aging process indicate the potential importance of this topic. Therefore, the primary...

Perception of dichotic chords (free recall and directed recall), nonsense syllables (CVs), and three-pair digits was assessed on 24 musicians and 24 nonmusicians. On the dichotic-CV and dichotic-digit free-recall tasks, there was a significant right-ear advantage, but there were no group differences. With the dichotic-chords, free-recall condition, a significant left-ear advantage was observed ...

Dichotic digit listening was made more difficult by interleaving one-, two-, three-, and four-pair digits within a test list in which the subjects did not know a priori the number of digit pairs presented on a given trial, thereby introducing listener uncertainty. Twenty right-handed (mean age = 26.8 years) and 20 left-handed adults (mean age = 24.0) with normal hearing and 40 right-handed adul...

BACKGROUND/AIMS Central auditory function can be studied to monitor the progression of mild cognitive impairment to dementia. Our aim was to address this issue in a prospective longitudinal setting. METHODS Tests of central hearing function were performed on 70 subjects with either Alzheimer's disease (AD) or mild cognitive impairment, and in controls with subjective memory complaints but nor...

PURPOSE To establish normative data for children and to characterize developmental differences in performance with the free recall version of the Randomized Dichotic Digits Test. RESEARCH DESIGN Group comparison of behavioral data derived from administration of the Randomized Dichotic Digits Test. STUDY SAMPLE Children from 10 to 18 years of age (167) and young adults from 19 to 28 years of...

background and aim: aging is associated with reduced cognitive abilities including attention and memory. there is some evidence that shows randomized dichotic digits test (rddt) has enough difficulty to show the ear asymmetry in dichotic listening. this study aimed to compare the effect of free and focused attention on dichotic listening ability of young and elderly listeners. methods: the cros...

background and aim: dichotic listening tests have been used to study right ear advantage (rea). fused dichotic rhymed word test (fdrwt), using rhymed words, is advantage­ous because of reducing the effect of attention on the test results. development of persian version of the fdrwt, and evaluation of its psychometric properties in normal children were the aims of the present study. methods: thi...
