The major purpose of this study was two-fold: to determine the level of achievement in selected library skills for freshmen at Central Washington State College (CWSC), and to determine which library skills, as delimited within a test, were possessed by those freshmen and which skills needed to be taught. This study was designed to test the…

It is hypothesized that children with hyperkinesis tend to repeat inappropriate behavior patterns more frequently than do other children. To assess this tendency to perseverate, a new scoring method using the Porteus Maze Test was devised. On a limited sample of children diagnosed as hyperkinetic and not hyperkinetic, analyses indicate that the…

The hypothesis that lessons which demand student involvement through leading a short discussion of required reading would result in greater attitude change in a liberal direction than would lessons taught by the lecture/discussion method was tested. Using members of four sections of a university course in communication, three sections received…

This paper is a first approach to the problems raised by the concept of experimentation in the field of functional literacy. It is divided into three main sections: (1) necessity, limits, and means of experimentation; (2) methods and fields of experimentation; and (3) the fields of experimentation. Hypotheses examined include: (1) The cultural…

In 27 preschoolers observed social activity was significantly and positively correlated with physical, verbal, direct, and indirect aggression in girls (physical and direct aggression, p .05; verbal and indirect aggression, p .01), but negatively correlated with all but verbal aggression in boys (all p's .01). Boys had high physical aggression…

A numerical procedure is outlined for obtaining an interval estimate of true score. The procedure is applied to several sets of test data. (Author)

Testing the hypothesis that socioeconomic status (SES) is related to altruistic behavior, 466 respondents derived from 4,799 households in rural Western Colorado (Woodland Park, Gunnison City, and Durango) were contacted to determine the degree of voluntary basement sharing that might be expected in the event of a nuclear crisis. Respondents were…

A general statistical model for the multivariate analysis of mean and covariance structures is described. Matrix calculus is used to develop the statistical aspects of one new special case in detail. This special case separates the confounding of principal components and factor analysis. (DEP)

Suppose P to the subpower of 1 and P to the subpower of 2 are two competing discrimination procedures. To compare the relative discriminatory power of both procedures, test statistics are suggested for the hypothesis that P to the subpower of 1 and P to the subpower of 2 performed no better than random assignment versus the alternative that P to…

The Dunnett procedure for comparing several treatment means with a control is applied to the problem of comparing several treatment variances with the variance of a control. Appropriate critical values are specified and an example is provided. (Author)

Attention has recently been drawn to experiments on the extent to which items can be recalled and recognized, and the overall level of recognition. A model proposing both direct-access and generation-recognition mechanisms in recall is shown to provide a satisfactory account of the phenomenon. (Editor)

Models relating individual and group problem solving solution times under the condition of limited time (time limit censoring) are presented. Maximum likelihood estimation of parameters and a goodness of fit test are presented. (Author/JKS)

Three dimensional contingency tables in which one variable is considered to be a factor and the other two variables have a natural relationship (such as left and right eye vision) are analyzed. Models involving symmetry and proportional symmetry between the related variables are also presented. (Author/JKS)

Statistical tests for determining whether one pole of an attitude scale is characteristic of a population are examined. A less restrictive procedure and the situations in which it might be used are discussed. (Author/JKS)

Discussed is a model for goal setting, which is based on Locke's theory that difficult but clear and specific goals, if accepted, will result in higher performance than easy goals, nonspecific goals, or no goals at all. (Author/RK)
