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)

Described are the methods and procedures of a research strategy for understanding the etiology of schizophrenia through the study of children at risk. (Author/IM)

Schizophrenic and normal subjects' responses to the Stanford-Binet Vocabulary items, the Wechsler Adult Intelligence Scale (WAIS) Vocabulary items, and the WAIS Similarities items were scored by two methods, one relatively strict and the other relatively lenient. (Editor)

Levitz and Ullmann's research (1969) was replicated, based on the findings that normal subjects can increase their number of uncommon associations in response to instructions and reinforcement. Results show that normals change their responses by means of an editing process and suggests this response is a "symptom" of normal flexibility rather than…

By assessing the competitive performance of schizophrenics on different types of tasks and by using nonschizophrenic groups, an attempt was made to determine more accurately whether schizophrenics respond differently to competition than nonschizophrenics, and if the effects of competition tend to be task-specific with schizophrenics. (Author/RK)

Several explanations have been offered in recent research for schizophrenic symptomatology within an interpersonal situation. This study attempts to separate two possible antecedent conditions, contextual emotionality and demand for self-disclosure, in order to clarify the immediate antecedents of symptomatic expression. (Editor/RK)

Thirty chronic schizophrenics (15 process and 15 reactive) and 15 normal control speakers described colors displayed in three-chip sets containing a referent and two nonreferent colors. Concludes that poor communication accuracy in long-term schizophrenics results from failure to include a self-editing stage as a part of the communication process.…

This paper examines methodological challenges inherent in conducting research on families of children with autism and in comparing these families with others who are coping with different types of disabilities or who have nondisabled children. Although most comparative research has contrasted families whose child has autism with those whose child…

This experiment tested a theory of schizophrenia which views the central defect as an inadequate integration of perceptual and cognitive processes. (Editor)

This study investigated the perceptual functioning of individuals whose Minnesota Multiphasic Personality Inventory (MMPI-168) profiles indicated schizophrenic tendencies, but who did not exhibit marked thought disorder. (Author)

The process of short-term memory scanning and recognition of common English words in 16 schizophrenics, 16 nonschizophrenic psychiatric patients, and 16 normals was investigated using the Sternberg item recognition procedure. This procedure has proved effective in isolating and clarifying the processes underlying mnemonic information processing.…

Recognition memory is one of the few areas of cognition in schizophrenia in which deficit has not been found. Such a finding has important theoretical implications for the understanding of schizophrenia. This research presents a study of recognition in long-term episodic memory in schizophrenia in which previous findings of no deficit were…

The objective assessment of thought disorder in schizophrenia is problematic in clinical psychology. Recently, an individually administered instrument (WIST) was introduced as a brief, objective, and quantitative measure of schizophrenic thought processes. Possible shortcomings of the WIST are noted; experimental findings that concern extension to…

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…

Reviews the methodological issues raised by previous research into the language used by thought-disordered and nondisordered schizophrenics. (FL)
