Patients with multiple sclerosis reported less left ear numbers but more right ear numbers than controls in a dichotic listening test. The multiple sclerosis patients were also relatively impaired on three learning tasks; one of these, a test for paired-associate learning of names and faces, correlated with left ear findings; the results are interpreted as supporting a hypothesised disconnectio...

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...

A tremendous amount of experimental work has attempted to identify reliable behavioural predictors of cerebral lateralization. Preferred handedness has been the most popular predictor, but some recent reports suggest that preferred footedness may serve as a more accurate predictor of functional laterality, especially in the left-handed population. The present study sought to test this claim by ...

Background: Individuals' listening styles differs based on their characters, professions and situations. This study aimed to assess the validity and reliability of Listening Styles Profile- Revised (LSP- R) in Iranian students. Methods: After translating into Persian, LSP-R was employed in a sample of 240 medical and nursing Persian speaking students in Iran. Statistical analysis was performed ...

BACKGROUND Far too little attention has been paid to the difference of Digit Span test and category verbal fluency test (CVFT) between normal and mild cognitive impairment (MCI) subjects. OBJECTIVE To investigate the difference of Digit Span test and CVFT between normal subjects and patients with MCI and study the influence of age, gender, and education on the task performance. MATERIAL AND...

Dichotic listening (DL) is the most frequently used method to study language lateralization. The current study investigated the effect of voice-onset-time (VOT) in dichotic listening with consonant-vowel (CV) syllables. Eighty-nine subjects with normal hearing and overall right-ear-advantage (REA) were tested with a PC version of the DL test. Voiced and unvoiced stop-consonants were used in com...

Background: The paced auditory serial addition test (PASAT) was primarily developed to assess the effects of traumatic brain injury on cognitive functioning. Working memory (WM) is one of the most important aspects of cognitive function, and WM impairment is one of the clinically remarkable signs of aphasia. To develop the Persian version of PASAT, an initial version was used in individuals wit...

The effect that the aging process has on recognition performance was studied using a hierarchy of 1-pair, 2-pair, 3-pair, and 4-pair dichotic digits (1, 2, 3, 4, 5, 6, 8, 9, and 10, male speaker). Two groups of right-handed subjects were studied: 20 adults < 30 years of age with normal hearing and 20 adults 60-75 years with mild-to-moderate hearing loss. Each of the multipaired sets contained t...

Studies using dichotic listening tests and electroencephalographic (EEG) measures of hemispheric asymmetry have reported evidence of abnormal brain laterality in patients having depressive disorders. We present new findings from a multigenerational study of risk for depression, in which perceptual asymmetry was measured in dichotic listening tests of emotional and verbal processing. Biological ...
