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 :Older adults with cerebrovascular accident (CVA) show evidence of auditory and speech perception problems. In present study, it was examined whether these problems are due to impairments of concurrent auditory segregation procedure which is the basic level of auditory scene analysis and auditory organization in auditory scenes with competing sounds.   Methods : Concurrent auditory...

OBJECTIVE To confirm that central auditory dysfunction (CAD) may be a precursor to the onset of Alzheimer dementia (AD). DESIGN Cohort study. SETTING Research study center. PARTICIPANTS Two hundred seventy-four volunteers from a dementia surveillance cohort were followed up for as long as 4 years after undergoing complete audiometric assessment. Twenty-one received a consensus diagnosis o...

INTRODUCTION Evaluation of the objective results in the clinical examination of central auditory disorders requires the use of reliable language tests which provide the means for the estimation of patients' audio-verbal communicative skills. MATERIALS AND METHODS The authors present a new set of more difficult language tests in Polish, including a filtered speech test, numeral and verbal dich...

Central auditory processing assessment has been used as a diagnostic tool for almost 50 years. The dichotic listening paradigm was introduced by Broadbent (1954) and, following Kimura’s first studies (1963), a large volume of research has been produced. Processing of auditory information during childhood may be altered if any predisposing factor is present during the course of development. Neur...

We compared auditory, cognitive, and language test results in a pair of dizygotic twins, one of whom showed symptoms of central auditory processing disorder (CAPD). Results highlight the importance of testing binaural function. In particular, electrophysiologic measures of dichotic listening effectively demonstrated the auditory-specific nature of this child's listening problems. The importance...

Objectives: All subjects suspected of Central Auditory Processing Disorder (CAPD) were previously tested by free recall dichotic digits test (DDT). The study objective was normalization and reliability evaluation of two-pair DDT in 750 native Persian subjects aged 8 to 12 years. Materials: A total of 750 subjects were divided into five age groups varying between 8 years and 12 years and 11 mon...

UNLABELLED Speech understanding disorders in the elderly may be due to peripheral or central auditory dysfunctions. Asymmetry of results in dichotic testing increases with age, and may reflect on a lack of inter-hemisphere transmission and cognitive decline. AIM To investigate auditory processing of aged people with no hearing complaints. STUDY DESIGN clinical prospective. MATERIALS AND M...

background and aim: aging is accompanied with changes in cognitive capacities. in spite of advances in neural imaging technologies, there is not a straightforward method to observe cognitive functions. for assessing brain functions, researchers mainly use psychometric tests. the aim of this study was using consonant-vowel (cv) dichotic test as a non-invasive behavioral test for auditory attenti...
