Objectives: The purpose of this research was to explore the possible differences in the working memory of monolingual (Persian) and bilingual  (Persian-Baluchi) children. We wanted to examine if there is a statistically significant relationship between working memory and bilingualism. Methods: Four working memory (WM) tests, assessing three WM components, were administered to 140 second...

Decreased information processing speed is often cited as the primary cognitive deficit occurring in conjunction with multiple sclerosis (MS). Two common tools for assessing this deficit are the Stroop Test and the Symbol Digit Modalities Test (SDMT). However, there are procedural variations in these rapid serial processing (RSP) tests pertaining to the response format (e.g., verbal or manual) a...

OBJECTIVES The purpose of the study was to examine recognition of degraded melodic stimuli in dichotic listening with or without frequency-place mismatch. DESIGN Melodic stimuli were noise vocoded with various number-of-channel conditions in a dichotic and monaural processor. In the dichotic zipper processor, the odd-indexed channels were tonotopically matched and presented to the left ear wh...

Subjects gave magnitude estimates of the loudness of monaurally presented pure tones (1000, 1040, and 1080 Hz) and dichotically presented pairs of tones (1000 Hz to one ear plus 1040 or 1080 Hz to the other). For each monaural frequency or dichotic pair, the magnitude estimates approximated power functions of sound pressure; moreover, the monaural and dichotic loudness functions were separated ...

We compared self-reported handicap (Hearing Handicap Inventory for the Elderly, HHIE) scores before and after a 6-week period of hearing aid use in subjects drawn from a pool of 115 elderly persons with hearing impairment. Study patients (PTs) were divided into two categories according to whether scores on a dichotic listening test (Dichotic Sentence Identification Test, DSI) were normal or abn...

Thirteen adult patients were operated on for symptomatic arachnoid cysts in the left temporal fossa; seven with an internal shunt procedure during local anaesthesia, and five with a craniotomy with fenestration of the cyst to the basal cisterns. In one patient, an initial internal shunt was transformed to a cystoperitoneal shunt. After surgery, all patients experienced relief of symptoms. Reduc...

Modern physiologically based models of the binaural system incorporate internal delay lines in the pathways from left and right peripheries to central processing nuclei. Different binaural models for the formation of dichotic pitch employ these delay lines in different ways. Consequently, the different models make different predictions for the relative strengths of dichotic pitches made with pa...

The market for self-monitoring of blood glucose (SMBG) approached $8.8 billion worldwide in 2008. Yet despite dramatic double-digit growth in sales of SMBG products since 1980, the business is now facing declining prices and slower dollar growth. Given that SMBG meters and test strips are viewed by consumers and insurers as essentially generic products, it will be extremely challenging for new ...
