Provides example applications of constrained principal component analysis (CPCA) that illustrate the method on a variety of contexts common to psychological research. Two new analyses, decompositions into finer components and fitting higher order structures, are presented, followed by an illustration of CPCA on contingency tables and the CPCA of…

Taxometric procedures provide an empirical means of determining which psychiatric disorders are typologically distinct from normal behavioral functioning. Although most disorders reflect extremes along continuously distributed behavioral traits, identifying those that are discrete has important implications for accurate diagnosis, effective…

The question asked in the present study is whether individuals record their experiences with sentences in a manner that provides information about the number of times the same basic meaning or idea has been expressed. (Author)

In two experiments on whether similarity grouping is based on the retinal or the perceived slopes of lines, observers judged the grouping of diagonal lines when a display of vertical and diagonal lines was presented upright and when it was slanted 75 degrees toward the floor. (Editor/RK)

If an attentional cue affects retroactive interference, perhaps a similar mechanism underlies release from proactive interference. This study tested this hypothesis by inserting an attentional cue before the final trial in Wickens' paradigm. (Author/RK)

Two experiments tested whether short-term memory accounts for the recency effect observed with rapid sequential presentation of nonverbal stimuli. (Editor)

The main purpose of the present work was to bring together methods that had generated different patterns of results in order to determine whether those differences would persist if the same subjects were performing the two types of tasks. (Author)

The purpose of the present investigation was to explore the extent to which a subject's ability to conjure up an image of a visual stimulus can substitute for the presence of that stimulus when a comparison with another is required. (Author/RK)

In this experiment an attempt was made to determine whether the perceptual system is capable of discriminating a moving pattern that is presented within the currently non-dominant field in binocular rivalry. (Author/RK)

It has been suggested that subliminal perception phenomena may be in part due to experimenter bias effects. Two studies that obtained positive evidence of subliminal perception were therefore replicated with experimenters tested under blind and not blind conditions. (Editor)

The purpose of this investigation was to explore two related aspects of the associations to compounds, particularly adjectival compounds. (Author/RK)

The recall of categories represented by varied versus repeated pictorial specimens was assessed with mixed and unmixed lists and with a control for the chance conjunction of particular subjects with particularly strong items when the items were varied. (Editor)

This study provides a cross-validation of several control/hostility scales by comparing mental health center patients who later were arrested for felony crimes with those who were not. (Author)

The purpose of this research was to study the feasibility of estimating the major CPI factors directly from CPI scale scores and to determine whether such estimates of factor scores could be used to formulate personality types. (Author)

THIS STUDY CRITICALLY EVALUATED MAJOR PUBLISHED STUDIES DEALING WITH PSYCHOLOGICAL AND EDUCATIONAL ASPECTS OF MENTAL RETARDATION AND PREPARED AN EXTENSIVE, DETAILED ANALYSIS OF RESEARCH METHODOLOGY ON THIS SUBJECT. THIS WAS A LIBRARY RESEARCH PROJECT IN WHICH A GREAT BODY OF LITERATURE WAS SURVEYED, ESPECIALLY PERIODICALS. SELECTED CLUSTERS OF…
