Some 80, white, schizophrenic patients were administered the Taylor Personality Scale of Manifest Anxiety (MAS), the Maudsley Personality Inventory (MPI) and were tested on an operant conditioning task. Hypotheses tested were: (1) effectiveness of social reinforcement (verbal approval) on a verbal conditioning task would be enhanced by subjecting…

The current interest in using non-professional therapists to work with chronic schizophrenics is usually focused on the effect on the patients. Relatively little attention has been paid to the effect this particularly intransigent patient population may have on clinically unsophisticated students, especially students who are planning a career as…

The present study reports data obtained from chronic schizophrenic patients which relate formal categories of language behavior to performance on the Stroop Color-Word Interference Test--a task of verbal encoding under distracting and nondistracting conditions. (Editor)

The relation between intelligence at admission and subsequent rehospitalization was examined in 91 schizophrenic males. (Editor)

A brief discussion of neurophysiology, neurotransmitters, and the effect of psychoactive drugs on brain diseases such as schizophrenia. (BB)

School and hospital records were used to examine childhood social competence, adult premorbid competence, and psychiatric outcome in adult schizoaffective, paranoid, and undifferentiated schizophrenics. A significant difference existed in childhood interpersonal competence and adult social competence among the subtypes. Results reflect…

This research examines different types of encoding strategies, in addition to semantic and organizational encodings, and their effects on schizophrenics' remembering. Based on Craik and Lockhart (1972), i.e., memory performance is a function of depth of encoding processing, this analysis compares schizophrenics' encoding processing with that of…

Explores whether it is possible to isolate some of the traditional cognitive controls in a group of seriously disturbed psychiatric patients then evaluates whether various diagnostic groups differ from each other and from normals with respect to these cognitive controls. (Author/RK)

This study compared the effects of contextual constraint, "the extent to which the choice of a particular word depends upon the words that precede it" (Miller and Selfridge, 1950), and list length on short-term recall of word lists by 24 chronic schizophrenics and 120 normal subjects. (Editor/RK)

Research shows a relationship between diagnoses of schizophrenia among twins. It was studied whether information that a twin was schizophrenic would bias diagnoses. Such information almost doubled the rater's estimates of probability of schizophrenia in a hypothetical case history. (NG)

Based upon reports of parents and guardians, with subjects at an average age of 21 years, it was found that 11 of the youngsters who had exhibited torque had in the interim been diagnosed as schizophrenic. (Author)

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)
