Tests three proposed attentional mechanisms as possible behavioral strategies by which schizophrenics could prevent relevant information from registering and considers whether stimulation coming through the visual or the auditory channels is differentially susceptible to motivated attempts to disattend to relevant information. (Author/RK)

The performance of hospitalized paranoid schizophrenics, nonparanoids, and hospitalized controls was compared on motor, perceptual, and cognitive tasks of increasing complexity. The data were examined within the context of comparing differential predictions made by input and central processing theories of information-processing deficit. (Editor)

Paranoid and nonparanoid schizophrenics were compared to normals in their performance on a sentence verification task. Results were related to past evidence and hypotheses about central processing performance among schizophrenics. (Editor/RK)

Assesses the effects of input and output interference on schizophrenic recall. Input interference is the interference resulting from the interpolation of items between presentation and recall of the probed item. Output interference is the interference resulting from the interpolation of responses between the presentation and recall of the probed…

Assesses the effect of an additional year of institutionalization on the dichotic listening performance of paranoid schizophrenics. (Author/RK)

A visual-spatial approach to the study of attention dysfunction was presented. The hypotheses of broadened and narrowed attention were tested by comparing peripheral visual discrimination of acute schizophrenic, chronic schizophrenic, and normal subjects within two regions of the functional visual field. (Editor)

This research was undertaken to explicate the role of behavioral rigidity and hypothesis behavior in concept learning of schizophrenics. (Author/RK)

While it is clear that schizophrenic patients often exhibit disordered thinking, the specific nature of the deficit and its role, either as a basis of abnormal behavior or as a symptom of malfunction in some underlying control process, remain to be clarified by research and by theory. Describes two experiments on the performance of conceptual…

The major aim of this research was to study the ability of schizophrenic patients to solve problems that involve abstract thought and to transfer training from one problem to another. (Author/RK)

Two differing explanations of schizophrenic processing deficit were examined: Chapman and McGhie's and Yates'. Thirty-two schizophrenics, classified on the acute-chronic and paranoid-nonparanoid dimensions, and eight neurotics were tested on two dichotic listening tasks. (Editor)
