Considerable research and theory have focused on the concept of life stress, defined as major changes occurring in an individual's life, such as divorce, loss of employment, or the death of a significant other. To examine the role of irrational beliefs in the life stress-depression relationship, 286 college students completed the Beck Depression…

In the present study Monte Carlo methods were employed to evaluate the degree to which canonical function and structure coefficients may be differentially sensitive to sampling error. Sampling error influences were investigated across variations in variable and sample (n) sizes, and across variations in average within-set correlation sizes and in…

A survey was sent to the principals of all regular public schools in the Cincinnati school district in April 1986 to determine the distribution of instructional computers in the schools and to examine the relationship of computer distribution to other school characteristics. Responses to the questionnaire were broken down by elementary,…

Correlation-based approaches to causal analysis contain too much irrelevant information that masks and modulates the true nature of causal processes in the world. Both causal modeling and path analysis/structural equations give the wrong answers for certain conceptions of causation, given certain assumptions about the "error" variables.…

The relationship between perceptual sensitivity and stimulus emotionality was investigated employing a methodology aimed to preclude the intervention of response variables. (Editor)

The purpose of this study was to determine what effects manifest anxiety has on the achievement of selected reading variables (also tasks or skills) of children who, according to their CMAS scores, vary in general drive or anxiety levels. (Author)

It is the purpose of this paper to investigate the chance nature of overfit as it relates to a regression formulation of research, to describe a model for projecting the overfit, and to empirically validate the model. (Author)

The purpose of the present study was to determine whether the reported relationship between IE scores and self-reported anxiety would be found when a nonobtrusive measure of aniety was employed. (Author)

In a previous paper (Hartley and Holt, 1971) the development of a three-minute reasoning test was described, and its validity and reliability assessed. In this paper three experiments are reported which look in greater detail at these aspects of the test in different situations. (Author)

Holland's hexagonal model for six occupational groups was tested with data on estimated occupational rewards. Data on rated occupational reward characteristics were available for 148 occupations. Although the hexagonal shape was distorted, the groups were arrayed in the order postualted by Holland. (Author)

The purpose of this study was to investigate the construct validity of the Occupational scales on the Strong Vocational Interest Blank. Five personality factors derived from the California Psychological Inventory were correlated with each of the Occupational scales. The significant relationships were consistent with Holland's personality theory of…

Presents a new approach for estimating missing observations together with the results of a Monte Carlo study of the relative strengths and weaknesses of this technique and three other available methods. These techniques are then examined with respect to their ability to use incomplete data to estimate the correlation matrix obtained using a full…

This paper considers the case of two predictor variables. Figures are obtained which show the regions of significance of joint regression coefficients, regression coefficients considered separately, and the multiple correlation. The intersection of these regions of significance and non-significance illustrates how the various apparent…
