The effect of compressed speech on the ability of right-hemisphere-damaged patients to use context.
The ability of RHD patients to use context under conditions of increased processing demands was examined. Subjects monitored for words in auditorily presented sentences of three context types-normal, semantically anomalous, and random, at three rates of speech normal, 70% compressed (Experiment 1) and 60% compressed (Experiment 2). Effects of semantics and syntax were found for the RHD and norm...
متن کاملImageability effects on sentence judgement by right-brain-damaged adults.
BACKGROUND: For decades researchers assumed visual image generation was the province of the right hemisphere. The lack of corresponding evidence was only recently noted, yet conflicting results still leave open the possibility that the right hemisphere plays a role. This study assessed imagery generation in adult participants with and without right hemisphere damage (RHD). Imagery was operation...
متن کاملRight unilateral spatial neglect of the left brain-damaged patients.
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...
متن کاملVisuo-motor control of the ipsilateral hand: evidence from right brain-damaged patients.
We investigated the extent to which the right hemisphere is involved in the control of the ipsilateral hand by analysing the kinematics of right-hand prehension in right brain-damaged (RBD) patients. We required patients to grasp one of five possible objects, equally-sized and distributed over a 40 degrees wide workspace. With the purpose of investigating the right hemisphere contribution to th...
متن کاملNo inherent left and right side in human 'mental number line': evidence from right brain damage.
Spatial reasoning has a relevant role in mathematics and helps daily computational activities. It is widely assumed that in cultures with left-to-right reading, numbers are organized along the mental equivalent of a ruler, the mental number line, with small magnitudes located to the left of larger ones. Patients with right brain damage can disregard smaller numbers while mentally setting the mi...
