Incidence and recurrence rates of anxiety disorders differed across four diverse developmental periods. The magnitude of comorbidity between anxiety disorders and MDD was comparable across periods.
The current study utilized a multiwave longitudinal design to examine whether dependency and/or self-criticism influence the course of depressive symptoms in a community sample of adults with a history of major depression. In addition, the authors examined whether self-esteem serves as a buffer against the development of depressive symptoms following increases in hassles in individuals possessing such traits. At Time 1, 102 participants completed measures assessing depressive symptoms, self-criticism, dependency, and self-esteem. Every 6 weeks for the next year, participants completed measures assessing depressive symptoms and hassles. High self-criticism was associated with greater elevations in depressive symptoms following elevations in hassles in low but not high-self-esteem individuals. Results with respect to dependency, however, were contrary to hypotheses. High dependency was associated with elevations in depressive symptoms following elevations in hassles in high-self-esteem individuals. In contrast, high dependency was associated with chronically elevated depressive symptoms in low-self-esteem individuals.
We collected data on grooming, proximity, and aggression in long-tailed macaques (Macaca fascicularis) in Kalimantan, Indonesia. We used this data to study how grooming influenced a receiver's (B) behavior towards the bout's initiator (A). In our first analysis, post-grooming samples were collected after A groomed B. These were compared to matched-control samples of similar conditions but A had not previously groomed B. This comparison was performed on 26 individuals (16 female, 3 male, 7 immature) and tested whether A's initial act of grooming increased the pair's time in proximity and the amount of time B groomed A. We also tested if A's grooming decreased B's aggression towards A per time in proximity. Rates of B-->A aggression per time in proximity with A for 39 individuals (18 female, 5 male, 16 immature) were compared between post-grooming and focal sample data. Finally, we studied 248 grooming bouts to test if the first two grooming episodes were time matched. We assessed the influence of age, sex, rank and inferred kinship on time matching, and controlled for individual variation and tendency to groom using a general linear mixed model. Our results showed that A-->B grooming acted to increase B-->A grooming and the pair's proximity, while lowering B-->A aggression. Despite these effects, episodes in grooming bouts were generally not matched, except weakly among similar partners (i.e., female pairs and immature pairs). Grooming imbalance was greatest across age-sex class (i.e., male-female and adult-immature pairs). In similar pairs, grooming duration was skewed in favor of high-ranking individuals. We conclude grooming established tolerance and increased the likelihood that grooming reciprocation would occur, but grooming durations were not typically matched within bouts. Lack of time matching may be the result of grooming that is performed to coordinate interchanges of other social services.
Previous research has indicated robust relationships between implicit motives and various indices of career preference and performance, with the implicit need for power (nPow) and the implicit need for achievement (nAch) found to associate with leadership and entrepreneurship, respectively. However, relatively little work has examined the relationships between implicit motivation and career intention. In the present study, 149 university students completed questionnaires assessing their intention to embark on entrepreneurial, professional, or leadership careers, while implicit motivation was measured using the picture story exercise. nPow was found to positively predict entrepreneurial intent and to negatively predict professional intent, while higher nPow was positively associated with both entrepreneurial and leadership career choice. nAch did not associate significantly with any of the intent or choice measures. These results tentatively suggest a previously undocumented relationship between nPow and entrepreneurial ambition, and possible differences in the motivational profiles of aspiring and actual entrepreneurs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
