An examination of previous claims for virtually perfect time-sharing in dual-task situations reveals confounding effects that may have obscured dual-task interference. Two experiments are conducted in which these confounding effects are minimized, revealing statistically significant dual-task interference. These results support the hypothesis that…

Some task variables that influence sentence coding, and the ways in which those influences appear to be manifested in performance were outlined. Trends in empirical data were examined as evidence for two classes of coding strategies. (Author/RK)

Research into brain physiology and dream psychology have helped to illuminate the biological purposes and processes of dreaming. Physical and functional characteristics shared by dreaming and television include the perception of visual and auditory images, operation in a binary mode, and the encoding of visual information. Research is needed in…

A series of four experiments was performed based on a model of human information processing. The model postulates four stages in the processing of an external stimulus: encoding (stage 1), central processing (stage 2), response selection, e.e. decoding (stage 3), and response execution (stage 4). The total reaction time can be decomposed into two…

Two accounts explain why studying pictures reduces false memories within the Deese-Roediger-McDermott paradigm (J. Deese, 1959; H. L. Roediger & K. B. McDermott, 1995). The impoverished relational-encoding account suggests that studying pictures interferes with the encoding of relational information, which is the primary basis for false memories…

Evidence is reviewed which suggests that there may be little or no direct introspective access to higher order cognitive processes. It is proposed that when people attempt to report on their cognitive processes they do not do so on the basis of any true introspection. (Editor/RK)

The knowledge-assembly theory is proposed to explain the acquisition, representation, and processing of knowledge. The theory assumes that both the representation and processing of knowledge change qualitatively as learning progresses. (Editor)

Article attempted to show that new findings are emerging that may bring the study of probability learning closer to the mainstream of research on human memory and information processing. (Author/RK)

Studies measured selective exposure to information by open-" and closed-minded" subjects within a consistency perspective. (Authors)

This research presents an integrative theoretical framework to explain and to predict psychological changes achieved by different modes of treatment. This theory states that psychological procedures, whatever their form, alter the level and strength of "self-efficacy". (Editor/RK)

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

This set of papers was originally developed for a conference on Issues and Directions in Mathematics Problem Solving Research held at Indiana University in May 1981. The purpose is to contribute to the clear formulation of the key issues in mathematical problem-solving research by presenting the ideas of actively involved researchers. An…

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)
