Intraorganizational and interorganizational job change: A discriminant analysis

Using March and Simon's (1958) participation model as a framework, this study employs the 1973–77 Quality of Employment Survey panel data to compare the determinants of intraorganizational and interorganizational job change. Two discriminant functions were significant, the first distinguishing between intraorganizational changers and stayers and the second between interorganizational changers and stayers. Moreover, the variables that distinguished between intraorganizational changers and stayers were either different from or opposite in influence to those distinguishing between interorganizational changers and stayers.     

Age differences in and correlates of identity status from college through middle adulthood

Adults ranging from 20 to 42 years of age were compared on the Extended Objective Measure of Identity Statuses, a questionnaire measure of identity statuses in the domains of ideological and interpersonal development. As hypothesized, compared to current college students, men and women over 30 years of age showed patterns of more mature identity development in both domains with the exception of foreclosure scores in the interpersonal domain that remained stable. Relationships between life commitments and identity statuses were analyzed separately for adults in their 30s compared to those in their 40s, revealing complex interactions with gender and normative cohort expectations. As hypothesized, relationships between identity statuses and adult commitments were more generally observed for the younger adult cohort, for whom individual differences in psychosocial development rather than age-related expectations might be expected to serve as determinants of early life choices.     

Some further tests of the brief confinement effect and the SSDR account of flooding

Although brief confinement in novel or fearful places may occasionally produce flooding-like effects with regard to hastening avoidance response extinction, the results of the three experiments reported here indicate that this is not as robust a phenomenon as is flooding. Experiments 1 and 2 found that any tendency for a brief confinement effect to occur is likely to result from the use of a procedure where extinction is started on the grid floor as opposed to on the ledge of a jump-up box. Experiment 3 found no evidence at all that confinement in either a novel or a fearful place can hasten the extinction of a more well-learned jump-up response than that studied in previous experiments, even when the grids extinction procedure was used. Overall these results do not support the SSDR account of flooding, which has derived its chief support from experiments demonstrating a brief confinement effect.     

Genetic and Environmental Contributions to Common Psychopathologies of Childhood and Adolescence: A Study of Twins and Their Siblings

We report findings based on analyses of self-reports of six common adolescent psychopathologies (attention deficit/hyperactivity disorder, ADHD; conduct disorder, CD; oppositional defiant disorder, ODD; generalized anxiety disorder, GAD; separation anxiety disorder, SAD; and major depressive disorder, MDD) in a sample of 1,162 male and female adolescent (12–19 years) twin pairs and 426 siblings. Prevalence statistics for past year and lifetime reports confirm differences between genders for CD, GAD, SAD, and MDD, and a lack of differences between twins and their non-twin siblings. Biometrical modeling was conducted to ascertain the relative influences of genes, and shared and non-shared environments contributing to these disorders. A more robust estimate of these parameters was obtained by including non-twin siblings. Age-specific thresholds were integrated into the analyses to appropriately model the developmental patterns of behavior. We found evidence for both genetic and non-shared environmental influences for all disorders. Shared environmental influences also seem to be important for MDD and lifetime GAD.     

Healthy Women, Healthy Men, and Healthy Adults: An Evaluation of Gender Role Stereotypes in the Twenty-first Century

An important question often asked when counselors-in-training read textbook discussion of gender role stereotypes, especially of older work such as the classic study by the Brovermans and their colleagues, is “Haven’t these biases been eliminated or at least reduced?” The current study was designed to replicate the work of the Brovermans and their colleagues to answer that specific question and to determine how current counselors-in-training perceive healthy adult women, healthy adult men, and healthy adults. As in the prior research, initial ratings of the social desirability of traditional gender role stereotypes were conducted, and the findings showed many similarities to past research. That investigation was followed by a modified Stereotype Questionnaire, based on the original work of Rosenkrantz, Vogel, Bee, I. Broverman, and D. M. Broverman (1968). Healthy adult women were found to be significantly different from healthy adult men as well as from healthy adults. In addition, the results suggest that there have been changes in counselors’ perceptions of healthy adults. Counselors-in-training were found to hold two standards for mental health—one for women and another for men.     

Spatial relational learning in rufous hummingbirds (Selasphorus rufus)

There is increasing evidence that animals can learn abstract spatial relationships, and successfully transfer this knowledge to novel situations. In this study, rufous hummingbirds (Selasphorus rufus) were trained to feed from either the lower or the higher of two flowers. When presented with a test pair of flowers, one of which was at a novel height, they chose the flower in the appropriate spatial position rather than the flower at the correct height. This response may also have been influenced by a preference for taller flowers as acquisition of the task during experimental training occurred more readily when the reward flower was the taller of the pair. Thus, it appears that although learning abstract relationships may be a general phenomenon across contexts, and perhaps across species, the ease with which they are learned and the context in which they are subsequently used may not be the same.
