Relations between first grade stress, temperament, and behavior problems

This paper examines relations between first grade stress, temperament, and behavior problems in 164 children after the completion of first grade. Specifically, the goals of the study were (a) to examine relations between both child and parent reports of the child's stress in first grade and behavior problems in school, (b) to determine if school stress interacts with the moderator variable temperament in predicting behavior problems, and (c) to examine such relations separately for boys and girls to assess if gender differences are present. Child and parent reports of the occurrence and upsettingness of 18 items associated with first grade were collected. Parents completed a temperament inventory; behavior problems were assessed by teacher ratings. Both child and parent reports of event upsettingness correlated significantly with externalizing behavior problems for boys, and with both internalizing and externalizing problems for girls. There was also evidence for interactions between first grade stress and temperamental characteristics in predicting externalizing behavior problems. Implications for research on childhood stress resulting from developmentally relevant life transitions are discussed.     

Relations between psychological stress and EEG correlations

In the present study inquiries have been made about the changes EEG cross-correlation in mental activities is subject to. The EEG recordings were made at rest, in visual and acoustical response, when reading and in the solution of an acoustical differentiation problem. In conjunction with plain reflex processes a decline in the intrahemispherical correlation was observed. During complex-structured psycho-request situations dissimilar changes in the EEG correlation have occurred on the scalp. Between the cerebral regions functionally essential for the solution of the problems, an increase in the bio-electric correlation and between other cerebral areas a decline were registered. The findings in conclusion come to realize that the topographic EEG cross-correlation analysis is appropriate to give an insight into the present situation of cerebral functional organization.     

Relations between the family environment scale (FES) and the MMPI

This study investigated the relations between FES scales and MMPI scales and the relation of social desirability and endorsement of FES items in a sample of 185 college students. FES scales were found generally not to be highly redundant with MMPI variables although MMPI Scale K (defensiveness) was significantly related to several FES scales. The social desirability and the endorsement rates of FES items were found to correlate approximately .80. Implications of these findings for the research and clinical use of the FES are discussed.     

Relations between embedded figures test performance and dimensions of the I-E scale

Relations between an embedded figures measure of field independence and various dimensions of Rotter's internal-external locus of control scale were investigated. The general absence of significant correlations suggests that these variables are essentially unrelated.     

Relations between mechanisms of CNS arousal and mechanisms of stress

In the centennial year of the birth of Hans Selye, this review compares his classical concepts of stress with a modern approach to mechanisms of CNS arousal. Relations between the two concepts are described. Neuroanatomical, neurophysiological, and functional genomic mechanisms underlying CNS arousal are briefly reviewed. Controls over stress responses and arousal are compared to particular concepts of control system engineering. Understanding these two systems is of crucial importance because their dysregulation is associated with large numbers of disease states.     

Visual discrimination of horizontal and vertical rectangles by rats on a new discrimination training apparatus

A new visual shape discrimination apparatus for use with rats is described. Rats were trained on a simultaneous discrimination using stereometric shapes, and the reward was milk which was delivered through the middle of the shapes. Animals were trained to discriminate vertical and horizontal rectangles on the apparatus, and it was found that they took as many trials to learn as on a Lashley jumping stand. Because of the speed at which individual trials may be conducted, less actual time is spent on training in this apparatus than in a Lashley jumping stand. Some transfer tests were conducted and indicated that: (1) although the bottom halves of the shapes were more important for rats than the top halves, animals had learned something about the shapes as a whole; (2) animals transferred to discontinuous shapes; (3) they transferred better to larger shapes than to smaller; (4) they had learned both to approach the positive shape, and to avoid the negative shape.     

Relations between stress and work outcomes: The role of felt challenge, job control, and psychological strain

Recent research on reported work stress indicates stress may not always be deleterious for an individual or organization. Research in this area, however, has not yet examined a variety of work outcomes, the mechanism by which stress leads to such outcomes, and the moderators of this effect. The present study hypothesized that two types of reported stress (challenge- and hindrance-related) have a divergent relationship with work outcomes (relating to desirable and undesirable outcomes, respectively) and a similar (positive) relationship with psychological strain. We also hypothesize felt challenge as a mechanism through which challenge stress relates to desirable outcomes and job control as a moderator of the effect. Results from a heterogeneous sample of university staff employees (N=461) supported many of the hypotheses. The two types of stress differentially related to work outcomes yet both positively related to psychological strain. In addition, felt challenge mediated the relationship between challenge-related stress and work outcomes, yet the effect of challenge-related stress did not depend on job control.
