Self-efficacy and resource allocation: support for a nonmonotonic, discontinuous model

Self-regulation theories are paving the way to integrating motivational theories of behavior. However, a review of the motivation literature reveals several possible relationships between self-efficacy and motivation. Past findings were reduced to 4 empirical models, which were compared within a single study using undergraduates playing a computer task. The effects of 2 manipulations of self-efficacy on resource allocation decisions were assessed. Consistent with a multiple goal process conceptualization, self-efficacy was found to relate positively to directing resources toward a goal but negatively to the magnitude of resources allocated for accepted goals. Differences in methods are used to reconcile current and past findings.     

A Dimensional Model of Psychopathology Among Homeless Adolescents: Suicidality,Internalizing, and Externalizing Disorders

The present study examined associations among dimensions of suicidality and psychopathology in a sample of 428 homeless adolescents (56.3% female). Confirmatory factor analysis results provided support for a three-factor model in which suicidality (measured with lifetime suicidal ideation and suicide attempts), internalizing disorders (assessed with lifetime diagnoses of major depressive episode and post-traumatic stress disorder), and externalizing disorders (indicated by lifetime diagnoses of conduct disorder, alcohol abuse, and drug abuse) were positively intercorrelated. The findings illustrate the utility of a dimensional approach that integrates suicidality and psychopathology into one model. Kevin A. Yoder and Susan L. Longley made equal contributions to this paper.     

Social Status, Not Gender Alone, Is Implicated in Different Reactions By Women and Men to Social Ostracism

Williams and Sommer found that ostracized women, but not men, worked harder on a subsequent collective task, speculating that women’s social compensation was motivated by threatened belongingness. The present 2?×?3 design with 180 U.S. women and men replicated this gender gap in work contributions then closed it using two status-manipulations that favored women’s task abilities or the higher education of undergraduates with high school partners. Additional analyses identified three clusters of participants who failed to compensate: only men in the replication control, women scoring low in self-monitoring, and participants who persisted unsuccessfully to resist exclusion. These patterns shift our focus away from gender and threatened belongingness toward control and status as explanations for the original gender difference.     

Can dogs defy gravity? A comparison with the human infant and a non-human primate

We conducted four experiments with 56 adult dogs (Canis lupus familiaris) involving tasks where food was dropped through an opaque tube connected either vertically or diagonally to one of two or three goal boxes. In the first experiment, modelled after studies with children and primates, the dogs first searched significantly more often in the location directly beneath the drop-off point (a gravity bias), although this box was not connected with the tube. These results are comparable to those of human infants and cotton-top tamarins. Experiments 2–4 tested which problem solving strategy the dogs applied to find the food. Results show that they do not understand the physical mechanism of the tube itself, and they apply one of three search strategies: search the gravity box (the one below the drop-off box); search the box in the middle; learn the correct location of the goal box. When the goal box was in the same location the dogs learned to search there over trials, that is, they learned to ‘defy gravity’, but when the location of the goal box changed over trials they showed no learning. These findings are compared with those from human infants and cotton-top tamarins: like these species, the dogs can learn to overcome a gravity bias, but only when the reward is to be found in a consistent location.     

Does “Making a Difference” Still Make a Difference?: A Textbook Author’s Reflections

Drawing on my experiences with teaching Psychology of Women and writing three editions of a textbook across two decades starting in 1990, I reflect on the core feminist call to make the personal political. By tracing the chronology and interplay of my textbook writing with my teaching, research, and editing, I speculate about an apparent disconnection between my experiences and research with students (who embrace the feminist call to make a difference) and the textbook market to veer toward less women-centeredness and activism in the pursuit of gender studies. I make my case that the activist goal of making a difference continues to make a difference in individual women’s lives, in women’s relationships, and in a social justice agenda.
