Examined the impact of information activation on individuals in different mood states. Results of two experiments suggest that happy mood supports judgmental inferences based on general knowledge structures, whereas sad mood facilitates the conservation of information. Findings support assertions that affective states influence the style of…

Discusses the relationship between personal knowledge in a domain and online searching proficiency in that domain, and the relationship between searching proficiency and database-assisted problem-solving performance based on a study of medical students. Search results, selection of terms, and efficiency were found to be related to problem-solving…

Examined self-perception during late adolescence as a correlate of individual temperament. Found that positive self-perception correlated with approaching, flexible, and positive mood patterns, and with high task orientation. Different aspects of self-perception showed distinct relationships with specific temperament dimensions. Noted men's and…

Examined the relationship of personality and physical variables to bulimic symptoms. Hierarchical regression analysis of a sample of Mexican American female students revealed that body mass and endorsement of United States societal values concerning attractiveness were related positively to bulimic symptomatology; age, body satisfaction, and…

The ability of 2 components, interpretation of a question and memory, to forecast the test-retest association coefficients of reading test items was studied with initial samples of 916 elementary and 949 secondary school students. For both populations, both components forecast the relative sizes of test-retest correlation coefficients. (SLD)

Develops a list of graded mathematical terms which gives a quick estimate of a child's reading ability in mathematics. Asserts that this instrument could identify students who need instruction in mathematics vocabulary and who have difficulty reading their mathematics textbooks. Finds a high correlation between teacher estimates and results…

This study compared the object naming, object recognition, reading, and spelling abilities of 22 adults, half with written language difficulties and half without. Significant positive relationships were obtained between object naming ability and reading ability, object naming and spelling, and reading and spelling performance. Results suggest that…

An equation derived by W. A. Nicewander and J. M. Price relating statistical power to reliability of dependent variable measures when true score regression is homogeneous across treatment conditions is enhanced through overcoming the problem of directly estimating the squared linear correlation between true scores for X and Y. (SLD)

A technique is presented to transform incomplete categorical data into complete data by imputing appropriate scores into missing cells. A solution of the optimization problem is suggested, and relevant psychometric theory is discussed. The average correlation should be at least 0.50 before the method becomes practical. (SLD)

The degree of agreement between two raters rating several objects for a single characteristic can be expressed through an association coefficient, such as the Pearson product-moment correlation. How to select an appropriate association coefficient, and the desirable properties and uses of a class of such coefficients--the Euclidean…

Describes an ongoing project that is investigating the correlation between journal cost and citation ratings in the fields of political science and genetics. Previous studies that relate journal costs to other variables are reviewed; the conceptual framework is explained; limitations of the study are considered; and further research is suggested.…

Investigated correlations between two intelligence measures for exceptional children. Corrected correlations between the tests indicated differences with correlations reported in one manual. Relationships were generally higher than those reported elsewhere. Implications are discussed, especially those involving the use of correlations between…

Three heuristic methods of assessing the dimensionality of binary item pools were evaluated in a Monte Carlo investigation. The indices were based on (1) the local independence of unidimensional tests; (2) patterns of second-factor loadings derived from simplex theory; and (3) the shape of the curve of successive eigenvalues. (SLD)

A brief overview is provided of the Conger-Lipshitz approach to estimating the reliability of a profile or test battery. A computational example from a recent study shows how canonical reliability can be obtained through existing statistical software. (SLD)

Describes a study comparing the grades of community college students under and over 25 years of age in selected classes at 6 Virginia community colleges. Older students had higher grades on their first major exam and higher final grades in both transfer and development courses. Reviews prior research. (DMM)
