TL;DR: Comparisons were made between mean scores obtained at the right and left ears, as well as between the handedness groups, and revealed that more left-handed subjects had ear leads which were the reverse of that found for the groups as a whole.

TL;DR: In this paper, a set of variable characteristics of aphasic speech was described, including rate of speaking, prosody, pronunciation, phrase length, effort, pauses, press of speech, perseveration, word use and paraphasia.

TL;DR: Techniques for study of speech physiology aberrations associated with neuromuscular disorders have been presented and two case descriptions are presented to illustrate the procedures used in attempts to specify the speech physiology problems of dysarthric subjects.

TL;DR: It was found that the Elithorn Mazes have by far the highest potential value in differential diagnosis and can be inferred, from the evidence presented, that this test differentiates right brain-damaged patients from those left brain- damaged patients who understand the instructions.

TL;DR: It is felt that the positive brain scan is as good as or better than any other localizing procedure now used for the study of aphasia in the living patient, but that additional refinements are possible and will further enhance the value of this technique.

TL;DR: In this paper, the authors trace the historical sequence of ideas which eventually permitted the discovery of the medullary crossing of the pyramids, the difficulties surrounding the acceptance of unilateral speech representation, the subsequent hemispheric dominance notions, the current neuropathological evidence questioning such ideas and EEG findings including EEG phase analysis data.

TL;DR: In this article, the authors examined the performance of patients with unilateral hemispheric lesions (57 left hemisphere-damaged patients and 54 right hemispere-Damaged patients) in order to ascertain which of these two factors, implicit verbal mediation and chromatic perceptual discrimination, play the greater role in the performance on two tests of shortterm memory of colored patterns.

TL;DR: In this article, the performances of 40 brain-damaged and 40 control patients on a temporal discrimination task were studied as a function of the interval separating the pair of tone durations compared and the position of the standard tone duration within each pair.

TL;DR: The results indicate that the two temporal lobes in man are not equally concerned with intensity discrimination and suggest further that the transverse gyri of Heschl in the left temporal lobe may be an important component of a descending auditory system.

TL;DR: In this article, two groups of adult aphasic individuals mastered two letter-prediction tasks, one group worked at the tasks daily; the other, on alternate days. But when retested a week after the terminal experimental session, they were found to have retained the tasks they had learned.

TL;DR: It is suggested that two opposite tendencies occur in braindamaged epileptic patients: a tendency towards shortening of RT as a consequence of epileptic discharges, and a tendency away from lengthening of RT a consequences of a severe brain lesion.

TL;DR: In this paper, the authors investigated the grammatical abilities of aphasics through the vehicle of spelling ability and assessed the correlation between age and spelling abilities and between educational level and spelling ability.

TL;DR: In this paper, a picture interpretation task, consisting of 4 TAT cards, was administered to 100 brain-damaged (BD) and 100 control (C) patients, and the results were interpreted in relation to differences in global mental impairment, attention, carefulness and incentive.

TL;DR: Visual temporal acuity (flicker detection) throughout the visual field has been found to be a more sensitive indicant of brain dysfunction than standard visual field examinations, largely due to non-specific and indirect effects of brain injury upon temporal resolving processes.

TL;DR: Patients with unilateral cortical lesions were given two tests of facial recognition, which required recognition of well-known faces and recognition from immediate memory of previously unknown faces, indicating that the tasks were tests of separate and distinct functions.

TL;DR: In this paper, the performance of brain-damaged patients on a series of tasks involving identification and cognition of colors was investigated systematically, including color matching, pointing to color, color verbal memory, and coloring drawings.

TL;DR: In this paper, an experiment of presenting competing verbal stimuli (digit sets) to left and right ears was carried out on a population of children and adolescents having lateralized brain damage of early onset.

TL;DR: It is suggested that spatial abilities might be differently organized in the two hemispheres, their representation being more focalized on the left and more diffuse on the right side of the brain.

TL;DR: The contribution of Carl Wernicke to the study of aphasia, a field which concerned Goldstein throughout his life, was discussed in a recent symposium as mentioned in this paper, where Goldstein was recognized as a pioneer in this field.

TL;DR: Findings seem to indicate that poor visual figure ground discrimination in brain-damaged patients may be due to the impairment of at least two specific abilities, i.e. language (or some intellectual factor closely related to it) and some other ability (perhaps a visuo-spatial ability), preferentially subserved by the right hemisphere.

TL;DR: Four syndromes are discussed in which there occurs failure of naming on confrontation, including anomia occurring as a manifestation of hysteria or malingering, that of non-aphasic misnaming which occurs in disorders which diffusely involve the brain.

TL;DR: There exists a “focus” within the posterior parietal region, along the posterior margin of area 2 of Brodmann and within the anterior extremity of the intra-parietal sulcus, such that a small removal from this focal area will give rise to more severe impairment than a removal of comparable size from elsewhere within the buttocks region.
