Frequency Theory, deriving from word recognition studies, was applied to immediate recognition of nonrepresentational pictorial items by 12-year old Ss. (Author)

An analysis of changes in CA, MA, and IQ in 324 patients, representative of the population of a hospital for mentally retarded, indicated that the decrement in IQ in mentally retarded children is due primarily to increases in CA and not to decreases in MA. It appears that MA is the more meaningful index of intelligence level. (Author/WY)

To a small degree, team teachers express more satisfaction with their work than do traditional teachers. (CK)

A study of various accents characteristics of certain groups in Great Britain and the prestige associated with these accents is presented. (CK)

The results of this study indicate that the most feasibly sized high school from an economic standpoint is a small one of approximately four to five hundred students. (CK)

The statistical power of nine k-sample tests against ordered location alternatives under completely randomized designs are investigated. The results are intended to aid researchers in selecting appropriate statistical procedures. (Author/JKS)

Methods for comparing the suitability of alternative models for covariance matrices are examined. A cross-validation procedure is suggested and its properties examined. A series of examples using longitudinal data are examined. (Author/JKS)

Current computer programs for analyzing linear structural models will apparently handle only two types of constraints: fixed parameter and equal parameters. In this paper, a method for imposing several types of inequality of parameter constraints is described. Several examples are presented. (Author/JKS)

An alternative analysis of the two-group single response variable design is proposed. It involves the classification of experimental units to populations represented by the two groups. Three real data sets are provided to illustrate the utility of the classification analysis. A table of sample sizes required for the analysis is presented.…

To determine the effect of violating the assumption of homogeneity of covariance for the Tukey Wholly Significant Difference (WSD) test, Monte Carlo simulations varied the number of treatment groups, sample size, and degree of covariance heterogeneity. As covariance heterogeneity was increased, the empirical significance levels increased beyond…
