A new inventory for assessing worry in managers: correlates with job involvement and self-reliance

This work introduces the ‘Worry Inventory for Managers’ (WIM), a 24-item measure of jobrelated worries in managers. A sample of 138 managers responded to the WIM and to measures of pathological worry, job involvement, and self-reliance. Factor analysis of the WIM revealed two facets of job-related worry, namely worry about

1. (1) organizational processes and about

2. (2) work overload.

Results indicate that job-related worry shows differential correlations from pathological worry with the three factors of self-reliance (counterdependence, overdependence, and interdependence).     

Coping with systematic bias during bilateral movement

The present studies examined the nature of kinematic interlimb interference during bilateral elbow movements of 1:1, 2:1 and 3:1 frequency ratios and the manner in which subjects cope with coordination bias. Analysis of movement trajectories in the first experiment indicated progressively greater angular velocity assimilation across 2:1 and 3:1 conditions. The desired temporal relationship was maintained by slowing or pausing the low-frequency movement at peak extension while the high-frequency arm produced intervening cycles. An increase in amplitude was also evident for concurrent, homologous cycles. Movement smoothness was emphasized and additional practice was provided in a second experiment. This resulted in dissociated peak angular velocity between limbs and eliminated hesitations and amplitude effects. Bias was still evident, however, as an intermittent approach toward a 1:1 ratio within each cycle. This systematic tendency was somewhat greater at the lower of two absolute frequency combinations but was not influenced by the role of each arm in producing the higher or lower frequency movement. The findings from the first experiment suggest that subjects initially accommodate interlimb kinematic assimilation, while producing the intended timing ratio, by intermittently slowing or pausing the lower-frequency movement. This attenuates the need for bilaterally-disparate movement parameters and provides additional time for organizing residual kinematic differences, perhaps reducing transient coupling. Evidence from the second experiment indicates that subtle relative motion preferences are still evident following sufficient practice to perform the movements smoothly. The within-cycle locations of the points of greatest interlimb bias for the 2:1 rhythms were positively displaced from those previously observed for 1:1 oscillations. The persistent coordination tendencies noted in both experiments perhaps reflect an assimilation/compensation cycle and constitute one potential source of the systematic error that often emerges during the acquisition of complex skills.     

Commentary on "Family dynamics and children in medical research.

Gordon and Bonkovsky describe a disturbing case of research involving minors in their article "Family Dynamics and Children in Medical Research." As presented in the case, there is little doubt that the assent obtained from the children was inadequate for the proposed research and that the institutional review board (IRB) failed to assess sufficiently the risk-benefit ratio of the research to the child-subjects.     

Attitudes Toward Rape Among African American Male and Female College Students

The purpose of this study was to investigate how African American male and female college students differ in their attitudes concerning rape. Two-hundred and ten college students completed a 12-item questionnaire designed to measure their views toward this issue. A 2-group multivariate analysis of variance (MANOVA) revealed statistically significant differences between African American men and women, with men being more accepting of stereotypes and myths about rape. These differences are discussed in the context of sexism and rape myths. Strategies for changing students' attitudes toward rape are proposed.     

The Effects of Cooperation and Competition on Ingroup-Outgroup Bias1

A matrix game format was employed in a 2 × 2 design to study the effects of within group cooperation and competition under conditions of success and failure on subjects' subsequent treatment of own group and outgroup persons. Subjects in two-person groups either succeeded or failed at a cooperative or competitive game and then awarded points (worth money) to themselves, their partner, and two other people. A review of the relevant literature suggested that ingroup-outgroup bias would be greater after successful competition than after unsuccessful competition. The results supported this hypothesis. It was also found that subjects in the Cooperation-Failure condition displayed greater ingroup-outgroup bias than subjects in the Cooperation-Success condition. A qualification of the previous research supporting a positive relationship between group cohesiveness and ingroup-outgroup bias was suggested on the basis of the results.     

School psychology and early education: Contributions of Boyd R. McCandless

The writings of Boyd R. McCandless and his colleagues concerned with socialization, sex role development, research methodology, early education, and the relationship of his work to school psychology and early education are discussed. McCandless' interests were diverse, but revolved around a central and continuous concern for those who have less access to experiences which are basic to productive and self-fulfilling lives. There is much in a review of this person's life and work that is instructive for both the academic and the practitioner.     

An investigation of relationships between teachers' ratings of behavior and children's personality traits

This study examined the relationships between teachers' ratings of children's behavior on the Behavior Problem Checklist and children's selfreported personality source traits on ageappropriate Personality Questionnaires. The sample consisted of 254 children from first through eighth grades and 13 teachers in a rural Maine elementary school. Analysis of the data revealed that teachers' ratings and children's self-reports in grades four through six agreed more frequently about problematic behavior than did children's self-reports and teachers self-ratings in grades one through three and seven and eight. In general, the study (1) supported the validity of teacher judgments made with the Behavior Problem Checklist, (2) demonstrated the ckitical need for more than one perspective when identifying and defining maladaptive behaviors potentially indicative of emotional disturbance, and (3) suggested the need to increase the accuracy of teachers' perceptions and evaluations of children's behavior.     

Some implications of computer networks for psychology

Computer networking as a subject of psychological research has varied facets, including the social psychology of scientists, the role of group “labeling” practices, and the paradigm development process, as well as the definitions of software, hardware, and communication systems and interfaces that fit the research styles, aspirations, and work habits specific to psychologists.     

The measurement of self-esteem for program evaluation

The purpose of this paper is to examine the area of self-esteem in the professional literature, its relationship to educational programs, its measurement problems, and one approach to program evaluation in terms of students' self-esteem. Self-esteem has been an important topic in the educational literature in recent years. There have been many important contributions by investigators on the relationship between self-esteem and educational achievement. Until recently, the results of self-esteem investigations have yielded a somewhat negative appraisal from reviewers, but there is optimism for the future possibilities of assessing this elusive construct. The investigator focusing upon program evaluation has advantages over his predecessors. He can utilize different measurement strategies. The strengths and criticisms of Q methodology are discussed. The L-L Q-Sort is presented as one approach to the evaluation of self-esteem in educational program evaluation.     

On a statistic arising in testing correlation

This paper is devoted to the study of a certain statistic,u, defined on samples from a bivariate population with variances ₁₁, ₂₂ and correlation . Let the parameter corresponding tou be . Under binormality assumptions the following is demonstrated. (i) If ₁₁ = ₂₂, then the distribution ofu can be obtained rapidly from theF distribution. Statistical inferences about = may be based onF. (ii) In the general case, allowing for _{11 22}, a certain quantity involvingu,r (sample correlation between the variables) and follows at distribution. Statistical inferences about may be based ont. (iii) In the general case a quantityt may be constructed which involves only the statisticu and only the parameter . If treated like at distributed magnitude,t admits conservative statistical inferences. (iv) TheF distributed quantity mentioned in (i) is equivalent to a certaint distributed quantity as follows from an appropriate transformation of the variable. (v) Three test statistics are given which can be utilized in making statistical inferences about = in the case ₁₁ = ₂₂. A comparison of expected lengths of confidence intervals for obtained from the three test statistics is made. (vi) The use of the formulas derived is illustrated by means of an application to coefficient alpha.This research was supported by the National Institute of Child Health and Human Development, under Research Grant 1 PO1 HD01762.
