Showing papers in "Neuropsychologia in 1971"


Journal ArticleDOI
TL;DR: An inventory of 20 items with a set of instructions and response- and computational-conventions is proposed and the results obtained from a young adult population numbering some 1100 individuals are reported.

33,268 citations


Journal ArticleDOI
TL;DR: Findings indicate the importance of kinesthetic sensation in the subject's own speech when learning to articulate and the auditory discrimination of syllables is possible through practice in speech and hearing from early childhood.

507 citations


Journal ArticleDOI
TL;DR: All monkeys with temporal lobe lesions achieved normal learning scores on nonspatial delayed alternation, but hippocampal monkeys were most efficient, while hippocampal lesion produced a deficit on spatial but not object reversals.

313 citations


Journal ArticleDOI
TL;DR: It has been demonstrated that auditory long-term memory functions are relatively intact, and that the disability is modality-specific to the auditory short-term store.

282 citations


Journal ArticleDOI
TL;DR: It is indicated that little or no syntactic capability exists in the right hemisphere and earlier indications of a right hemisphere speech capacity could not be confirmed.

223 citations


Journal ArticleDOI
TL;DR: Difference between right and left handed reading was investigated in two experiments, finding children were found to be faster and more accurate when reading with fingers of the left than the right hand, and adults no difference was found.

180 citations


Journal ArticleDOI
TL;DR: In this paper, the alpha activity was recorded bilaterally in a sample of 10 high and 10 low hypnotizable subjects, under task conditions designed to activate first the left and then the right hemispheres.

177 citations


Journal ArticleDOI
TL;DR: Comparability of effects of prefrontal ablations to the rat is extended and the inference of the existence of the system in this species' frontal lobe is permitted.

163 citations


Journal ArticleDOI
TL;DR: Twenty normal Ss performed a monocular tachistoscopic word recognition task, and right field superiority was significant across all Ss.

155 citations


Journal ArticleDOI
TL;DR: The results show that left-sided cortical lesions produce significant impairment in the rapidity of repetitive movements with the ipsilateral as well as with the contralateral arm, whereas right-sided lesions produce impairment of movement in the contralsateral arm only.

Journal ArticleDOI
TL;DR: It is suggested that the naming impairment in demented patients may be largely attributable to an impairment of visual recognition, and the two processes of recognising and of labelling have some independence in that they can be independently impaired.

Journal ArticleDOI
TL;DR: Two experiments were carried out using the free recall of lists of words which suggest that both the hypothesised factors operate to produce the overall memory disorder in demented patients.

Journal ArticleDOI
TL;DR: The results are interpreted as supporting the conclusion that the right hemisphere plays a distinctively important role in mediating spatial perception in the tactile as well as in the visual and auditory modalities.

Journal ArticleDOI
TL;DR: Results showed that the span of retention for Korsakoff patients deteriorated significantly faster than either of the two non-brain-damaged groups for materials consisting of either CCC's, one-word or three-words.

Journal ArticleDOI
TL;DR: The results of a systematic study on the effects of medial thalamic lesions in the rat are summarized and interpreted and a role of inhibitory control is ascribed to the CM-Pf complex.

Journal ArticleDOI
TL;DR: The hypothesis that the impairment of the right brain-damaged patients on tasks of complex visual perception may be due, at least in part, to unilateral spatial neglect is supported.

Journal ArticleDOI
TL;DR: The effectiveness of “cued” recall in the amnesic group was demonstrated and this finding is related to an interpretation of theAmnesic syndrome in terms of disinhibition.

Journal ArticleDOI
TL;DR: Two experiments tested the hypothesis that right field recognition superiority (RFRS) in bilateral tachistoscopic word recognition is partly determined by the time of arrival of the two stimuli at left hemisphere language centers, suggesting that temporal factors are importantly involved in this RFRS.

Journal ArticleDOI
TL;DR: Right-handers exhibit a consistent superiority of the right visual half-field for recall of digits; this superiority may reflect the more direct connections between theright visual half field and the speech areas of the left hemisphere.

Journal ArticleDOI
TL;DR: The results give only partial support to the possibility that motor behaviour is differentially controlled by the two hemispheres, but are in general agreement with prior experiments.

Journal ArticleDOI
TL;DR: A direct test of this hypothesis revealed that patients with Huntington's Disease were impaired in a task embodying this compensation function but were unimpaired in other equally difficult spatial-motor tasks not involving this function.

Journal ArticleDOI
TL;DR: Behavior testing for interhemispheric integration in a commissurotomized boy with asymmetric cortical damage indicates a compensatory strengthening in the ipsilateral somesthetic representation of the left hand in the left hemisphere.

Journal ArticleDOI
TL;DR: An analysis of matching tasks in terms of memory demands has two advantages: it accounts for some variations in the difficulty of matching by eye and by hand, and it suggests an analysis of “visual” and “tactual” task in terms that may cut across modalities.



Journal ArticleDOI
TL;DR: It is claimed that careful neuropsychological analysis of memory defects is essential if the authors are to understand the basic factors upon which they depend and the role of the brain in the memory process.

Journal ArticleDOI
TL;DR: Methods for testing and analyzing behavioral deficits in aphasia were derived from a functional analysis of stimulus-response relations (the stimulus control of behavior), demonstrating that repeated testing over a prolonged time may reveal changes in deficit classification that would have been unsuspected on the basis of early tests only.

Journal ArticleDOI
TL;DR: The contingent negative variation, or CNV, a slow, surface negative potential which appears maximally in frontal regions of the brain of man during psychophysiological states of preparation set or expectancy, is shown in a non-patient population to be smaller in amplitude in high anxiety S than in low anxiety S in a moderately stressful experimental situation.

Journal ArticleDOI
TL;DR: Spatial errors were most pronounced in S s with low performance scores on the WISC whether or not their language scores were relatively high, and unlike either normal children or normal and brain-damaged adults, the S of this study had inordinate difficulty taking diagonal routes.

Journal ArticleDOI
TL;DR: It is concluded that the appearance of the ipsilateral somatosensory evoked response goes roughly parallel to the appearance and distinctness of definitive handedness.
