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 mont...

Introduction: Emotional words in comparison with neutral words have different hemispheric specialization. It is assumed that the right hemisphere has a role in processing every kind of emotional word. The objective of the present study was the development of a Persian version of the dichotic emotional word test and evaluate its validation among adult Persian speakers.   Materials and Methods: ...

OBJECTIVE The aim of present study was to verify possible cognitive dysfunction in the patients with Juvenile Myoclonic Epilepsy (JME) and its correlation to factors related to epilepsy and patients demographic variables. MATERIAL AND METHODS Thirty two consecutive patients with JME and 32 healthy controls were evaluated in neuropsychological domains including orientation, mental control, log...

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...

Background: The paced auditory serial addition test (PASAT) was primarily developed to assess the effects of traumatic brain injury on cognitive functioning. Working memory (WM) is one of the most important aspects of cognitive function, and WM impairment is one of the clinically remarkable signs of aphasia. To develop the Persian version of PASAT, an initial version was used in individuals wit...

background and aim: today, bilingualism is a developing phenomenon which half of the world population is bilingual. auditory system is the main route to language learning, so it is expected that bilingualism has an effect on functions of the auditory system. auditory memory is one of the auditory processes which is a cornerstone of linguistic skills and learning process growth, so that, it has ...

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...

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...

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 ...
