The abstraction of prototypical information and the classification of new exemplars was investigated as a function of category size and the number of categories that had to be distinguished during learning. (Editor)

The present series of experiments attempted to analyze more fully the contributions of stimulus-reinforcer and response-reinforcer relations to autoshaping within a single conditioning situation. (Author)

Four experiments examined the effects of various instructions on the rate of false recognitions of synonyms, antonyms, nonsemantic associates, and homonyms. (Editor)

Article compared reception with selection stimulus-presentation procedures as research methods in human conceptual behavior. (Author/RK)

Article attempted to find whether there are experimental paradigms that can be employed to determine a sensory scale that is capable of accounting for judgments of differences, ratios, and similarities. (Author/RK)

The central thesis of the present article is that balance theory (Heider, 1946, 1958) or affective-cognitive consistency theory (Rosenberg, 1956, 1965; Rosenberg & Abelson, 1960) provides a framework that can be used to account for all dissonance results . (Author/RK)

The present experiments were directed to the general question of how grouped presentation affects recall and organization. (Author)

The purposes of the present experiments were to attempt to reproduce the Estes and Taylor (1964) results (the number of items identified from a many-item array was as much as twice the full-report span of four or five items) and to compare them with the number of items reported in the full-report procedure.

Previous work on recalling prose material can be criticized for its limited use of quantitative analysis and for neglecting the theoretical implications of the distinctions between verbatim and other forms of recall. Nine specially written passages used clauses and actual words to split reproduced material into verbatim, non-verbatim and intrusive…

Analyzed choices made by researchers concerning factor model, retention criteria, rotation, interpretation of factors and other issues relevant to factor analysis. Results indicate that choices made by researchers have generally been poor and that reporting practices have not allowed for informed review, cumulation of results, or replicability.…

Attempts to determine how far orthodox concept attainment tasks are representative of corresponding real-world activity. (Author/RK)

Evaluates the effect of E's sex on the word association and concomitant state of physiological arousal of hospitalized schizophrenic Ss. (Author/RK)

Compares spatial with nonspatial reasoning ability within the same patients to determine whether spatial reasoning deficits in schizophrenics are specific to spatial types of tasks or are indicative of generalized reasoning difficulties. (Author/RK)

Tests the relationship between the success of psychotherapeutic efforts and the client's expectation-reality discrepancy, i.e., as the number of disconfirmed expectations increases the possibility for successful psychotherapy (positive therapy outcomes and low drop out rates) decreases. (Author/RK)

The experiment in physics has often been pictured as an ideal for the less mature social sciences, especially by positivist philosophy of science. The thesis to be presented here is that the physical experiment as a paradigm for psychology is merely a pretext, a smoke-screen for a more fundamental and concealed technological paradigm for the study…
