We are concerned with the hypothesis that two variables have a perfect disattenuated correlation, hence measure the same trait except for errors of measurement. This hypothesis is equivalent to saying, within the adopted model, that true scores of two psychological tests satisfy a linear relation. A statistical test of this hypothesis is derived…

Describes study that investigated the effects of progressive phases of computer literacy on undergraduate students' attitudes, values, and opinions toward information technology (IT) and its applications. The Linear Structural Relations (LISREL) model is explained, and the implications of the findings of this study for changing negative attitudes…

Presents a model that suggests the cognitive style and personality traits that are likely to affect programming stages and empirically investigates 1 portion of that model with 192 college students. Correlations between results from the Group Embedded Figures Test and design and coding tasks are discussed. (LRW)

Describes a study that established a measure and model for use in predicting and explaining electronic mail systems as an example of computer-mediated communication technologies usage and choice. The results indicated that all of the eight hypotheses showed significant correlation between criterion and predictor variates, supported by different…

Given the social nature of many tasks involved in exploring and committing to a career, we hypothesized that social anxiety would correlate to exploration and commitment, even after controlling for general anxiety. We also hypothesized that self-construal and gender would interact with social anxiety in relation to exploration and commitment. In a…

Purpose: The correlation between organizational unit managers' leadership styles and the level of organizational learning in their units was tested. Design/methodology/approach: A positive correlation was hypothesized between transformational leadership and organizational learning as manifested by organizational learning mechanisms--OLMs (the…

The double-deficit hypothesis of dyslexia posits that reading deficits are more severe in individuals with weaknesses in phonological awareness and rapid naming than in individuals with deficits in only one of these reading composite skills. In this study, the hypothesis was tested in an adult sample as a model of reading achievement. Participants…

This study examined the correlates of symptom-seeking behavior for Alzheimer's disease (AD) among middle-aged persons. Symptom seeking, the tendency to search for signs of disease, is one manifestation of an individual's concern about developing AD. The data were obtained from a survey of two subsamples of 40-60 year old adults: 1) 108 adult…

The decline in standardized test scores during the 1960s and 1970s is well documented and is seen in both aptitude and achievement test scores. This paper describes and analyzes the test score trends over the 1960s, 1970s and early 1980s for five aptitude tests: (1) the Scholastic Aptitude Test; (2) the American College Test; (3) the Preliminary…

A survey of 317 faculty members at three institutions of higher education in western Pennsylvania was conducted to determine how online reference services and library automation affect the attitude of faculty toward several variables: (1) centralization or decentralization of online reference services; (2) willingness to learn to use and pay for…

The purpose of this research was to determine, through multiple regression analysis, the strength of the relationship of each of six predictor variables (undergraduate major, undergraduate grade-point average (GPA), graduate major, graduate GPA, Graduate Record Examinations (GRE) Quantitative score, and GRE Verbal score) to academic achievement…

The pretest-posttest design referred to as Design 2 by Campbell and Stanley (1963) is commonly used in educational research and evaluation. The tenability of the assumption of a zero population difference commonly used with this design is questioned. A nonzero population estimate based on the mean difference observed in test-retest reliability…

The degree to which the chosen units of analysis are likely to produce spurious findings in staged combinations of multiple linear regression procedures are examined. The effects of grouping variables (e.g., classroom, school, and school district) on Procedures such as Coleman's semipartial regression and Mayeske's commonalities, in light of…

In order to determine whether the kind of process underlying cloze responses is indeed a systematic and exhaustive search, a study was conducted exploring some corollaries to such a search hypothesis. It was assumed that subjects would generate responses representing a number of word types, that some of these word types would be sensible and some…

We concern ourselves with the hypothesis that two variables have a perfect disattenuated correlation, hence measure the same trait except for errors of measurement. This hypothesis is equivalent to saying, within the adopted model, that true scores of two psychological tests satisfy a linear relation. Statistical tests of this hypothesis are…
