In numerous applications of the analysis of variance, it is necessary to compute the power of F tests having numerically high alpha (significance) levels. This article tabulates the power of F tests for a variety of degrees of freedom. (Author/JKS)

One approach to the problem of analyzing classroom interaction by use of a Markoff chain is presented. The two sections of the paper present (1) a discusion of Hoel's test of order of a Markoff chain, and a Likelihood Ratio Criterion (LRC) for a two-dependent Markoff chain is given, and (2) a discussion of possible adjustments of Darwin's LRC with…

This study tested competing interpretations of IQ deficit in schizophrenic patients. One interpretation (concomitancy hypothesis) holds that IQ loss is a product of schizophrenic symptoms and is remedied as the symptoms remit. The second (prodromal hypothesis) holds that IQ deficit preceeds and facilitates the development of schizophrenic disorder…

Previous research investigating the relationship of attraction and aggression has yielded somewhat equivocal results. The present study investigated the influence of two variables, attitudinal similarity and exposure, on interpersonal attraction and physical aggression. (Editor)

The present study was designed to assess the cortical concomitants of selective mode-specific attention in subjects differing in the capacity for sustained attentional involvement. (Editor)

The present study predicted that, if arousal is unitary, then stressors which separately induce it should be additive in their effects on behavioral efficiency. (Editor)

Special cases of the factor analysis model are developed for four selection situations. Methods are suggested whereby parameters in each case can be estimated using a maximum likelihood procedure recently developed by Joreskog. (Author)

Videotapes of two 17-month old children -- each child sometimes described as a boy and sometimes as a girl -- were shown to 85 adult middle-class subjects, who rated attributes of the children on questionnaires containing sex role items. (Authors/RY)

Forty-nine Ss learned a unidimensional concept with a six-dimensional stimulus set. Instructions specified the 12 possible unidimensional concepts, and the response on each trial was to give confidence ratings to each of the 12 corresponding hypotheses. (Author)

The absolute normal scores test is described as a test for the symmetry of a distribution of scores about a location parameter. The test is compared to the sign test and the Wilcoxon test as an alternative to the "t"-test. (Editor/RK)

If intentional forgetting is to be understood, research must focus on the specification of exactly how memory search and decision processes are altered when a subject is instructed to forget. This research addresses that problem. (Author/RK)
