Cognitive processing among schizophrenia participants, entailing encoding of presenting stimulation into a format facilitating collateral processes (e.g., memory search), is examined in light of stochastic mathematical models of performance. Results implicate additional encoding operations (encoding subprocesses) as the source of schizophrenia enco...

The Eckblad and Chapman (1983) Magical Ideation Scale was administered to groups of paranoid and nonparanoid schizophrenics and control subjects. Schizophrenics were found to score significantly higher than nonschizophrenic psychiatric patients (mainly cases of affective disorder) and normal control subjects. The potential theoretical and prognosti...

Inconsistent findings within certain areas of schizophrenia research--processing of verbal and pictorial stimuli, and hemispheric functional asymmetry--suggest the importance of examining the attentional resources associated with the cerebral hemispheres among schizophrenics. A cognitive task battery was developed which assessed the functioning of...

The experimental work on cognitive processes in schizophrenia is critically reviewed with respect to its relevance in understanding schizophrenic symptomatology. Several logical and empirical issues that complicate any comprehensive attempt to relate schizophrenic symptoms and information processing are discussed. Studies germane to schizophrenic s...

Imagery and verbal aspects of schizophrenic informational performance were examined. Pictorially and verbally presented pairs of items were compared with respect to both pronounceability of their names and their real-life sizes. Results indicated slower stimulus encoding of pictorial than verbal stimulation among the schizophrenics, especially para...

Three experiments were conducted employing a continuous measure of conditional stimulus/unconditional stimulus (CS/US) contingencies as perceived by the subject (i.e., subjective contingency or SC). It is argues that direct measurement of relational learning, as indexed by SC, can lead to a better understanding of Pavlovian conditioning processes....
