Neuropsychological deficit and regional cerebral blood flow in schizophrenic patients.

The paper examined the relationship between the scales of the Luria Nebraska Neuropsychological Battery and measures of cerebral blood flow in a sample of 51 chronic schizophrenic patients without a history of brain damage. Of 88 correlations between the two sets of data, 22 were significant at the .05 level.

The Luria-Nebraska Neuropsychological Battery and the Peabody Individual Achievement Test: a correlational analysis.

A group of 100 neurological, psychiatric, and normal subjects were administered both the Luria-Nebraska Neuropsychological Battery and the Peabody Individual Achievement Test. Correlations between LNNB subtests that tap skills necessary for academic achievement (Reading, Writing, Intellectual Processes, Arithmetic) and corresponding PIAT subtests were high. Correlations between LNNB Localization scales and PIAT scores were also high, with the left Parietal-Occipital Scale showing the highest correlation.

Comparison of two methods of administering the Halstead Category Test.

Developed an alternative method of administering Halstead's Category Test that uses answer sheet and latent image developer. The method does not entail bulky apparatus operated by the examiner. There is lessened possibility of examiner error in providing reinforcement and in recording responses.
