Formulas for estimating cross-validated hit-rates, the number of correct classifications into an a priori grouping structure, were examined. The following mathematical formulas were compared: McLachlan's formula estimator, two Snappin and Knoke smoothed formula estimators, and the analytic leave-one-out estimator. The R method was included as a…

Two experiments were performed to study inductive reasoning as a set of thought processes that operates on the structure, as opposed to the content, of organized memory. The content of the reasoning consisted of inductions concerning the names of mammals, assumed to occupy a Euclidean space of three dimensions (size, ferocity, and humanness) in…

This study uses two methods of analysis to examine the degree to which items within the cells of the Hill Interaction Matrix correlate. It is found that the table of specifications does not hold up. But the author recommends caution in interpreting this finding. (Author/BP)

Defining population diversity as the distribution along a continuum of homogeneity to heterogeneity with respect to one or more variables, measures are described with variance-based interpretations which can be applied to qualitative data. It is possible to use these statistics to define relationships in multivariate distributions. (Author/CTM)

This study investigated both relational and physical aggression in preschool children, explored potential differences in informant reporting and child sex on these subtypes, and examined relationships between types of aggressive behaviors and other types of negative and positive social behaviors. Naturalistic observations of social behavior,…

Overview: Behavioural data reveal an inverted U-shaped function in the efficiency of prospective memory from childhood to young adulthood to later adulthood. However, prior research has not directly compared processes contributing to age-related variation in prospective memory across the lifespan, hence it is unclear whether the same factors…

Although the primary use of the speaking section of the Test of English as a Foreign Language Internet-based test (TOEFL[R] iBT Speaking) is to inform admissions decisions at English medium universities, it may also be useful as an initial screening measure for international teaching assistants (ITAs).
