A dual task priming investigation of right hemisphere inhibition for people with left hemisphere lesions

Differential effects of semantic and identity priming in patients with left and right hemisphere lesions.

Abstract Patients with single brain lesions in the anterior or posterior left and right hemispheres and a group of controls were studied in two priming experiments. The first experiment employed associative pairs (DOCTOR-NURSE) and the second employed identical pairs (NURSE-nurse). Short and long prime-target stimulus onset asynchronies (SOAs) (i.e., 250 and 1850 msec) were manipulated within b...

Illness Narrative Complexity in Right and Left-Hemisphere Lesions

A variety of reading disability associated with right hemisphere lesions.

Dyslexia, the apparently selective impairment in the ability to read words, or even individual letters, has been repeatedly described in association with left (major) hemisphere lesions. Verbal dyslexia, affecting the reading of words but not of isolated letters, may be characterized by paralexic errors (misreading of words). The paralexias may accompany similar (paraphasic) errors in spoken sp...

A Case Report of A Persian Patient with Crossed Aphasia: Agrammatism after Right Hemisphere Lesion

Crossed aphasia in dextral (CAD) refers to aphasia occurring after right brain damage in dextral persons. CAD is a rare phenomenon in the world and there has not been any report of crossed aphasia in Persian, that is why we measured to report a Persian patient with crossed aphasia and this is a first report of incidence of CA in Persian. In this case report study, we offered a complete report o...

Letter-case-specific priming in the right cerebral hemisphere with a form-specific perceptual identification task.

In a form-specific perceptual identification task, subjects identify and write letter strings in the same letter case as they appear on a computer display. Letter-case-specific repetition priming was observed in this task when test items were presented directly to the right hemisphere, but not when they were presented directly to the left hemisphere, similar to results in previous word-stem com...
