Contaminants in drinking water, such as lead, nitrate, and arsenic, have been linked to negative physical health outcomes. We know less, however, about whether such pollutants also predict mental health problems and, if so, the conditions under which such effects are strongest. In this longitudinal study, we examined whether drinking water contaminants interact with negative family environments (parental psychological control) to predict changes in depressive symptoms in 110 adolescents—a developmental period when symptoms often first emerge. We found that for adolescents in psychologically controlling families, levels of drinking water contaminants prospectively predicted depressive symptoms 2 years later; this effect was not present in adolescents in non‐controlling families. Importantly, these associations were not accounted for by family‐ or community‐level socioeconomic resources, demographic features, or by the adolescents’ stress exposure. These findings highlight the interplay of physical and psychological environments in influencing depressive symptoms in adolescents.

Normal-hearing students (n = 72) performed sentence, consonant, and word identification in either A (auditory), V (visual), or AV (audiovisual) modality. The auditory signal had difficult speech-to-noise relations. Talker (human vs. synthetic), topic (no cue vs. cue-words), and emotion (no cue vs. facially displayed vs. cue-words) were varied within groups. After the first block, effects of modality, face, topic, and emotion on initial appraisal and motivation were assessed. After the entire session, effects of modality on longer-term appraisal and motivation were assessed. The results from both assessments showed that V identification was more positively appraised than A identification. Correlations were tentatively interpreted such that evaluation of self-rated performance possibly depends on subjective standard and is reflected on motivation (if below subjective standard, AV group), or on appraisal (if above subjective standard, A group). Suggestions for further research are presented. 相似文献

Focusing on similarities between the mood regulation approach and dissonance theory, this article addresses the interplay between dissonance and mood by examining how individuals search for information after making a decision while under the influence of positive versus negative mood. Study 1 suggested that negative mood increased the preference for consonant over dissonant information after decisions, whereas positive mood led to a more balanced information search. In Study 2, participants in negative mood rated consonant information as more pleasant and dissonant information as more annoying than participants in positive mood. In addition, the results suggested that mood regulation processes took place. In Study 3, the findings from Study 1 were replicated with a paradigm in which higher stakes were involved. 相似文献

Jonas Landberg PhD 《Suicide & life-threatening behavior》2009,39(4):452-460
The aim of this paper was to estimate how suicide rates in the United States are affected by changes in per capita consumption during the postwar period. The analysis included Annual suicide rates and per capita alcohol consumption data (total and beverage specific) for the period 1950–2002. Gender‐ and age‐specific models were estimated using the Box‐Jenkins technique for time series analysis. No significant estimate was found for males. For females the total alcohol estimate (0.059) was significant at the 10% level whereas the spirits estimate was significant with an effect of 0.152. The results imply that a change in U.S. per capita consumption would result in a change in female suicide rates, whereas the male rates would not be affected. 相似文献

Late Abrahamic reunion? Religious fundamentalism negatively predicts dual Abrahamic group categorization among Muslims and Christians 下载免费PDF全文
Although extensive research has documented the effectiveness of common or dual in‐groups on improving intergroup relations, little is known about how individual‐difference variables affect people's willingness to make such re‐categorizations in the first place. Here, we demonstrate that individual differences in religious fundamentalism predict willingness to categorize in terms of the common Abrahamic religious origins of Christianity and Islam among Christians and Muslims. Study 1 (n = 243 Christians, 291 Muslims) uses multigroup structural equation modeling and Study 2 (n = 80 Christians) an experimental manipulation to show that religious fundamentalism causes lower dual Abrahamic categorization, which, in turn, predicts more positive attitudes toward the respective out‐group, mediating the negative effects of religious fundamentalism on religious intergroup bias. While making the general case that individual differences may play important roles for dual categorizations, these results also highlight the specific positive potential of dual ecumenical categorizations for improving interreligious relations. Research and societal implications are discussed. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

Effects of testing on subsequent re‐encoding and long‐term forgetting of action‐relevant materials: On the influence of recall type 下载免费PDF全文
Veit Kubik Lars‐Göran Nilsson Jonas K. Olofsson Fredrik U. Jönsson 《Scandinavian journal of psychology》2015,56(5):475-481
Testing one's memory of previously studied information reduces the rate of forgetting, compared to restudy. However, little is known about how this direct testing effect applies to action phrases (e.g., “wash the car”) – a learning material relevant to everyday memory. As action phrases consist of two different components, a verb (e.g., “wash”) and a noun (e.g., “car”), testing can either be implemented as noun‐cued recall of verbs or verb‐cued recall of nouns, which may differently affect later memory performance. In the present study, we investigated the effect of testing for these two recall types, using verbally encoded action phrases as learning materials. Results showed that repeated study–test practice, compared to repeated study–restudy practice, decreased the forgetting rate across 1 week to a similar degree for both noun‐cued and verb‐cued recall types. However, noun‐cued recall of verbs initiated more new subsequent learning during the first restudy, compared to verb‐cued recall of nouns. The study provides evidence that testing has benefits on both subsequent restudy and long‐term retention of action‐relevant materials, but that these benefits are differently expressed with testing via noun‐cued versus verb‐cued recall. 相似文献
