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 The...

BACKGROUND The authors reviewed the evidence regarding the existence of age-related declines in central auditory processes and the consequences of any such declines for everyday communication. PURPOSE This report summarizes the review process and presents its findings. DATA COLLECTION AND ANALYSIS The authors reviewed 165 articles germane to central presbycusis. Of the 165 articles, 132 art...

background and aim: the double dichotic digit test (ddt) is a simple test for assessing and screening auditory processing system. the purpose of this study was to develope a double ddt, in persian language and find its basic norm values in girls aged 7 to 11 years. methods: the persian version of double ddt is composed of 3 different 25 numerical lists. numbers in each list were recorded dichot...

OBJECTIVE Using signals processed to simulate speech received through cochlear implants and low-frequency extended hearing aids, this study examined the proposal that low-frequency signals facilitate the perceptual organization of broader, spectrally degraded signals. DESIGN In two experiments, words and sentences were presented in diotic and dichotic configurations as four-channel noise-voco...

BACKGROUND auditory processing and co-occurrence of pathologies. AIM to investigate the performance of children with Dyslexia and attention deficit hyperactivity disorder (ADHD) in behavioral and auditory processing tests, comparing the results to a control group. METHOD participants of the study were 30 children, with ages between 7 and 12 years, divided into three groups: a control group ...

background and aim: research shows that 13-18 percent of the people suffer from tinnitus, almost 5 percent of which, have chronic or bothersome tinnitus. chronic tinnitus may be accompanied by anxiety, depression, insomnia, and impairment in cognitive functions such as memory and attention. the purpose of this study was to compare the verbal auditory memory and divided attention between individ...

Seniors often have more difficulty understanding speech than younger adults, particularly in noisy environments. While loss in peripheral hearing sensitivity explains many of the listening problems of elderly persons, age-related declines in general cognitive skill and central auditory processing also appear to contribute. In this article, we focus primarily on the effects of age on central aud...

Sensorineural loss is characterized by increased hearing threshold, reduction in the dynamic range of hearing and loudness recruitment, and increased temporal and spectral masking, resulting in degraded speech perception. Several techniques including spectral contrast enhancement, multi-band frequency compression, and dichotic binaural presentation have been investigated for reducing the advers...

OBJECTIVE The association between deficits in verbal processing skills and disruptive psychopathology remains one of the most frequently replicated findings in all of child psychiatry. This study uses a dichotic consonant-vowel listening test to examine the potential neural basis for this association. METHOD A series of 87 young boys recruited from a sample at risk for disruptive disorders re...

Two patterns of appropriately filtered acoustic white noise can be binaurally fused by the human auditory system to extract pitch and location information that is not available to either ear alone. This phenomenon is called dichotic pitch. Here we present a new method for generating more effective and useful dichotic pitch stimuli. These novel stimuli allow the psychophysical assessment of dich...
