OBJECTIVES Various studies have demonstrated that organic solvent exposure may induce auditory damage. Studies conducted in workers occupationally exposed to solvents suggest, on the one hand, poorer hearing thresholds than in matched non-exposed workers, and on the other hand, central auditory damage due to solvent exposure. Taking into account the potential auditory damage induced by solvent ...
OBJECTIVE We measured late cortical potentials in a psychophysical procedure for binaural unmasking of a dichotically-embedded pitch. METHODS Late-latency auditory evoked potentials were measured from 128 recording channels in 13 healthy subjects. Control stimuli consisted of 500 ms segments of broadband acoustic noise presented identically to both ears via earphones, evoking a perception of ...
OBJECTIVE To assess the effect of memory impairment on central auditory function. DESIGN Case-control study. SETTING The Virginia Merrill Bloedel Hearing Research Center, Seattle, Washington. PARTICIPANTS The study cohort of 313 volunteers from a dementia surveillance research program comprised 3 groups: (1) controls without memory loss (n = 232); (2) memory-impaired participants with mil...
background and aim: auditory processing disorders may have detrimental consequences on a child’s life, if undiagnosed and untreated. the multiple auditory processing assessment (mapa), as a valid model, has been introduced for central auditory processing assessment and diagnosis in school children. the purpose of this study was to design and evaluate the persian version of mapa for auditory pro...
Subjects heard two lists of 4 items each presented simultaneously to the two ears at a rate of four pairs of items per sec. A recall cue presented immediately after the test list signalled report of 4 of the 8 items. In recall by spatial location, the cue indicated whether the items on the right ear on left ear should be recalled. In recall by category name, the cue indicated the superset categ...
In previous behavioral studies, a prime syllable was presented just prior to a dichotic syllable pair, with instructions to ignore the prime and report one syllable from the dichotic pair. When the prime matched one of the syllables in the dichotic pair, response selection was biased towards selecting the unprimed target. The suggested mechanism was that the prime was inhibited to reduce confli...
Dichotic stimulus pairs were constructed with one word that was emotionally neutral and another that evoked either negative or positive feelings. Temporal and spectral overlap between the members of each pair was so great that the two words fused into a single auditory percept. Subjects were consciously aware of hearing only one word from most pairs; sometimes the emotion-evoking word was heard...
