■ Durational patterns provide cues to linguistic structure, and so variations in rhythm skills may have consequences for language development. Understanding individual differences in rhythm skills, therefore, could help explain variability in language ability across the population. We investigated the neural foundations of rhythmic proficiency and its relation to language skills in young adults...

BACKGROUND central auditory processing and exposure to metallic mercury. AIM to evaluate the performance on tests of central auditory processing in adolescents exposed to metallic mercury. METHOD participants were 52 adolescents, of both genders, who presented hearing thresholds within normal limits. The study group (SG) was composed by 21 adolescents who worked on the burning of gold-mercu...

OBJECTIVE To assess cognition in major depressed (MD), Alzheimer's disease (AD), and depression in AD elderly. METHOD Subjects were evaluated by Mini Mental, Rey Auditory Verbal Learning Test, Rey Complex Figure, Digit Span, Similarities, Trail Making A/B, Verbal Fluency and Stroop. One-way ANOVA and multivariate models were used to compare the performance of each group on neuropsychological ...

OBJECTIVE To determine the effects of a formal auditory training program on the behavioral, electrophysiological and subjective aspects of auditory function in individuals with bilateral high-frequency hearing loss. METHOD A prospective study of seven individuals aged 46 to 57 years with symmetric, moderate high-frequency hearing loss ranging from 3 to 8 kHz was conducted. Evaluations of audi...

OF THESIS Objects can be identified from a number of perceptual attributes, including visual, auditory and tactile sensory input. The integration of these perceptual attributes constitutes our semantic knowledge of an object representation. This research uses functional neuroimaging to investigate the brain areas that integrate perceptual features into an object representation, and how these re...

Auditory agnosia refers to the defective recognition of auditory stimuli in the context of preserved hearing. There has been considerable interest in this topic for over a hundred years despite the apparent rarity of the disorder and potential diagnostic confusion with deafness or even Alzheimer's disease (Mendez and Rosenberg, 1991—see Case P593 below). Following Lissauer's (1890) distinction ...

The supramarginal gyrus (SMG) is activated for phonological processing during both language and verbal working memory tasks. Using rTMS, we investigated whether the contribution of the SMG to phonological processing is domain specific (specific to phonology) or more domain general (specific to verbal working memory). A measure of phonological complexity was developed based on sonority differenc...

Functional neuroimaging has highlighted a left-hemisphere conceptual system shared by verbal and nonverbal processing despite neuropsychological evidence that the ability to recognize verbal and nonverbal stimuli can doubly dissociate in patients with left- and right-hemisphere lesions, respectively. Previous attempts to control for perceptual differences between verbal and nonverbal stimuli in...

The audiometric and self-assessed handicap data of 180 elderly persons with presbyacusic-type hearing impairment were submitted to principal components analysis in order to study the factor structure underlying auditory processing. Audiometric data included pure-tone threshold sensitivity, speech understanding scores for monosyllabic words without competition, synthetic sentences within competi...

Pure word deafness is a disorder of auditory verbal comprehension without dysfunction of speaking, reading, or writing. This rare symptom arises from bilateral lesions in the temporal lobes or disconnection between the primary auditory cortex and Wernicke’s area. I present a right-handed 33-year-old woman who presented with pure word deafness and complex auditory hallucination with intermittent...
