Early Adversity and the Prospective Prediction of Depressive and Anxiety Disorders in Adolescents

The current study was a prospective exploration of the specificity of early childhood adversities as predictors of anxiety and depressive disorders in adolescents. Participants were 816 adolescents (414~males, 402 females) with diagnostic information collected at age 15; information on early adversities had been collected from the mothers during pregnancy, at birth, age 6 months, and age 5~years for a related study. Adolescents with pure anxiety disorders were compared with adolescents with pure depressive disorders (major depressive disorder, dysthymia), and these groups were compared to never-ill controls. Analyses controlled for gender and maternal depression and anxiety disorders. Results indicated that adolescents with anxiety disorders were more likely than depressed youth to have been exposed to various early stressors, such as maternal prenatal stress, multiple maternal partner changes, and more total adversities, whereas few early childhood variables predicted depressive disorders. Even when current family stressors at age 15 were controlled, early adversity variables again significantly predicted anxiety disorders. Results suggest that anxiety disorders may be more strongly related to early stress exposure, while depressive disorders may be related to more proximal stressors or to early stressors not assessed in the current study.     

Preschool language exposure and use: A comparison study of dual-language learners and English monolingual children

This study explored the language experiences of dual language learners (DLL; n = 19) and English monolinguals (EM; n = 13) in preschool classrooms where English is the primary language of instruction and many home languages are present. Using the Language ENvironment Analysis™ system as a primary tool, we quantitatively analysed an average of 34 hours of recordings collected over 5–8 days for each participating child (M_age = 52 months) in six classrooms. Results showed that, during a typical preschool day, DLLs spoke as much as EMs but received less adult talk overall and had more 5-min segments with zero adult–child conversations than their EM peers. Follow-up analyses revealed that teachers generally talked less when children initiated the conversations than when adults initiated the conversations, and this pattern was particularly evident for DLLs. Study implications and future research are discussed.     

Predicting Personality Stability Across the Life Span: The Role of Competence and Work and Family Commitments

Longitudinal studies suggest modest continuity in personality from adolescence to early adulthood and greater continuity over successive periods during the adult years. However, individual differences in personality stability do exist. We discuss potential sources of personality change, especially as they relate to development, role assumption and commitment, and loss of roles and commitments. Then, using data from the Intergenerational Studies, we employ measures of competence and of work and family commitments, assessed both in high school and adulthood, to predict personality stability from high school to early and late adulthood. Results indicate that personality stability can be successfully predicted with such measures. Greater personality stability is found for those determined to be more planfully competent, but additional family and work role variables also increase predictive power, in some instances. Using two alternate measures of competence—one from the California Q-sort and the other from the California Psychological Inventory—we replicated the finding that men with more disorderly careers show less personality stability, and that women who have experienced more divorces show less personality stability.     

Representation in the mental lexicon: Implications for theories of the generation effect

Three experiments investigated the finding by McElroy and Slamecka (1982) that the “generation effect” (the retention advantage for self-produced over read items) is not obtained when artificial, meaningless nonwords are used as the to-be-remembered items. In Experiment 1, some subjects were asked to generate or read items that they thought were words, but, in fact, were not; no generation effect was found. In Experiment 2, subjects were taught definitions to experimenter-created items. Despite the fact that these subjects could readily retrieve each item’s assigned semantic properties, no generation effect was found. Finally, Experiment 3 examined the read]generate variable as a function of an item’s frequency of use in the language. Whereas medium- and high-frequency words produced large generation effects, no comparable effects were found for low-frequency words or nonwords. These results indicate that representation in the mental lexicon is a necessary, but not a sufficient, condition for the generation effect. Rather, it may be necessary to consider how related the generated item is to other potential retrieval cues in the memory system.     

Visual search asymmetries in motion and optic flow fields

In visual search, items defined by a unique feature are found easily and efficiently. Search for a moving target among stationary distractors is one such efficient search. Search for a stationary target among moving distractors is markedly more difficult. In the experiments reported here, we confirm this finding and further show that searches for a stationary target within a structured flow field are more efficient than searches for stationary targets among distractors moving in random directions. The structured motion fields tested included uniform direction of motion, a radial flow field simulating observer forward motion, and a deformation flow field inconsistent with observer motion. The results using optic flow stimuli were not significantly different from the results obtained with other structured fields of distractors. The results suggest that the local properties of the flow fields rather than global optic flow properties are important for determining the efficiency of search for a stationary target.     

Body, society, and subjectivity in religious studies

Attention to bodies has transformed the study of religion in the past thirty years, aiding the effort to overcome the discipline's Protestant biases by shifting interest from beliefs to practices. And yet much of this work has unwittingly perpetuated an individualist notion of the religious subject. Although religionists are now well aware that bodies cannot be studied apart from the social forces that shape them, all too often the religious subject stands alone in a crowd, participating in communal rituals, subject to religious authorities and disciplinary practices, but oddly detached from intimate relationships. In this article, I first argue that the turn to the body was motivated by what it appeared to reject: theoretical questions about subjectivity. I then seek to challenge prevailing trends by arguing that these same theoretical insights should now prod us to attend to the import of intimacy and personal relationships.     

Expanding stress generation theory: test of a transdiagnostic model

Originally formulated to understand the recurrence of depressive disorders, the stress generation hypothesis has recently been applied in research on anxiety and externalizing disorders. Results from these investigations, in combination with findings of extensive comorbidity between depression and other mental disorders, suggest the need for an expansion of stress generation models to include the stress generating effects of transdiagnostic pathology as well as those of specific syndromes. Employing latent variable modeling techniques to parse the general and specific elements of commonly co-occurring Axis I syndromes, the current study examined the associations of transdiagnostic internalizing and externalizing dimensions with stressful life events over time. Analyses revealed that, after adjusting for the covariation between the dimensions, internalizing was a significant predictor of interpersonal dependent stress, whereas externalizing was a significant predictor of noninterpersonal dependent stress. Neither latent dimension was associated with the occurrence of independent, or fateful, stressful life events. At the syndrome level, once variance due to the internalizing factor was partialed out, unipolar depression contributed incrementally to the generation of interpersonal dependent stress. In contrast, the presence of panic disorder produced a "stress inhibition" effect, predicting reduced exposure to interpersonal dependent stress. Additionally, dysthymia was associated with an excess of noninterpersonal dependent stress. The latent variable modeling framework used here is discussed in terms of its potential as an integrative model for stress generation research.     

Elevated Appraisals of the Negative Impact of Naturally Occurring Life Events: A Risk Factor for Depressive and Anxiety Disorders

The tendency to appraise naturally occurring life events (LEs) as having high negative impact may be a predisposing factor for the development of depression and anxiety disorders. In the current study, appraisals of the negative impact of recent LEs were examined in relationship to depressive and anxiety disorders in a sample of 653 adolescents who were administered diagnostic and life stress interviews at ages 15 and 20. Participants’ appraisals of the negative impact of LEs reported at age 15 were statistically adjusted using investigator-based ratings to control for objective differences across LEs. Higher appraisals of the negative impact of LEs were associated with both past and current depressive and anxiety disorders at age 15 and predicted subsequent first onsets of depressive and anxiety disorders occurring between ages 15 and 20. In addition, appraisals of the negative impact of LEs were particularly elevated among those experiencing both a depressive and anxiety disorder over the course of the study. The findings suggest that systematically elevated appraisals of the negative impact of LEs are a predisposing factor for depression and anxiety disorders and may represent a specific risk factor for co-morbid depression and anxiety in mid-adolescence and early adulthood.
