This article reviews and synthesizes recent research regarding auditory processing, attention, and their roles in generating both adaptive and maladaptive behavioral responses. Research in these areas is beginning to converge on the role of polymorphisms associated with catecholamine metabolism and transport, particularly the neurotransmitter dopamine. The synthesis offered in this article appe...

The sense of hearing is the fastest of our senses and provides the first all-or-none action potential in the auditory nerve in less than four milliseconds. Short stimulus evoked latencies and their minimal variability are hallmarks of auditory processing from spiral ganglia to cortex. Here, we review how even small changes in first spike latencies (FSL) and their variability (jitter) impact aud...

Introduction: Tinnitus is a perception of sound without external source. For complete assessment of tinnitus, central auditory processing abilities should be considered in addition to the routine psychological evaluation of tinnitus characteristics. Temporal processing is one of the important auditory skills that are necessary for complex higher level auditory processing.   Materials and Method...

PURPOSE This study compared the temporal processing performance of children with phonological disorders submitted to formal and informal auditory training. METHODS Fifteen subjects with phonological disorder (pure tone thresholds ≤20 dBHL from 0.50 to 4 kHz, and age between 7 years and 10 years and 11 months) were evaluated, divided into three groups: CONTROL GROUP five subjects (mean age 9...

The symptoms of two patients with bilateral cortical auditory lesions evolved from cortical deafness to other auditory syndromes: generalised auditory agnosia, amusia and/or pure word deafness, and a residual impairment of temporal sequencing. On investigation, both had dysacusis, absent middle latency evoked responses, acoustic errors in sound recognition and matching, inconsistent auditory be...

Central auditory processing disorders among school-age children have been challenging to identify and treat. Many issues remain that need to be resolved. Here, we compare and contrast findings on 331 school-age children who were given two of the more common central auditory processing disorder tests (Staggered Spondaic Word [SSW] Test and the SCAN Screening Test for Auditory Processing Disorder...

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...
