a b s t r a c t introduction:we investigated differential role of cortical and subcortical regions in verbal and non-verbal sound processing in ten patients who were native speakers of persian with unilateral cortical and/or unilateral and bilateral subcortical lesions and 40 normal speakers as control subjects. methods: the verbal tasks included monosyllabic, disyllabic dichotic and diotic tas...

High traffic density can be expected to increase the attentional processing requirements of driving. Establishing methods of assessing the differential demands placed on drivers by environmental variables has been the focus of a recent series of investigations. Results of an initial examination of the impact of traffic density on mental workload are reported here. The current investigation util...

The Paced Auditory Serial Addition Task (PASAT) is a neuropsychological instrument designed to measure attention, working memory and speed of information processing in complex manner. It currently used evaluate different neurological diseases. the purpose this study was establish PASAT normative data for healthy Italian population using standardized methodology Equivalents Scores. brief auditor...

We present a case that is unusual in many respects from other documented incidences of auditory agnosia, including the mechanism of injury, age of the individual, and location of neurological insult. The clinical presentation is one of disturbance in the perception of spoken language, music, pitch, emotional prosody, and temporal auditory processing in the absence of significant deficits in the...

The challenge of understanding how the brain processes natural signals is compounded by the fact that such signals are often tied closely to specific natural behaviors and natural environments. This added complexity is especially true for auditory communication signals that can carry information at multiple hierarchical levels, and often occur in the context of other competing communication sig...

The basis for multiple representations of equivalent frequency ranges in auditory cortex was studied with physiological and anatomical methods. Our goal was to trace the convergence of thalamic, commissural, and corticocortical information upon two tonotopic fields in the cat, the primary auditory cortex (AI) and the anterior auditory field (AAF). Both fields are among the first cortical levels...

A review of research examining the relationship of auditory-visual integration and reading achievement is presented. The techniques of meta-analysis were used to integrate statistically the findings from 31 studies. A total of 146 correlations were collected and aggregated across assessment procedures, reading skills, grade levels, and subject characteristics. Also, partial correlations and a s...

Purpose: The objective of this research was to assess the auditory abilities of Portuguese children and compare such abilities to the score of the Scale of Auditory Behaviors (SAB). Methods: Fifty-one children were evaluated with audiometry, speech audiometry, acoustic immittance measures, and eight behavioral tests involving dichotic listening, monotic listening, temporal processing, and sound...
