background: pragmatics is appropriate use of language across a variety of social contexts  that  provides accurate interpretation   of   intentions.   the   occurrence    of   the right hemisphere lesions can interfere with pragmatic abilities, and particularly with the processing of nonliteral speech acts. methods: since the objective of this study was to assess different  aspects of pragmatic...

Right unilateral spatial neglect (USN) was investigated on three left brain-damaged patients suffering from the right homonymous hemianopsia and hemiplegia. A test battery consisted of visuo-constructive praxis; 1) putting blocks into a box, 2) bisecting a horizontal line, 3) figure drawing, 4) drawing of a dial plate and 5) copying drawing. The investigation revealed that USN of left brain-dam...

To explain the prevalence of unilateral spatial neglect in patients with right brain damage, Heilman et al have suggested that the attentional neurons of the right parietal lobe might have bilateral receptive fields, whereas the homologous cells of the left hemisphere would have strictly contralateral receptive fields. One implication of this theory is that patients with right brain damage shou...

Hemispheric specialization for spatial frequency processing was investigated by measuring the contrast sensitivity curves of sine-wave gratings in 30 left or right brain-damaged patients using different spatial frequencies compared with healthy participants. The results showed that left brain-damaged patients were selectively impaired in processing high frequencies, whereas right brain-damaged ...

OBJECTIVE To study eye movements during cervical proprioceptive stimulation by passive body rotation in darkness, with the head held stationary, in patients with right brain damage and hemineglect. BACKGROUND At very low frequency, this stimulation is reported to produce an illusion of head turning in space and eye deviations directed opposite to trunk rotation (in the direction of the illuso...

Two subtests—Sarcasm Comprehension and Metaphor Comprehension—of Gardner and Brownell’s (1986) Right Hemisphere Communication Battery, adapted to Hebrew, were administered to 27 right-brain-damaged (RBD) patients, 31 left-brain-damaged (LBD) patients, and 21 age-matched normal controls. RBD patients tended to score somewhat lower than LBD patients on Sarcasm Comprehension METAPHOR AND SYMBOL, 1...
