This study aims to explore the relationship between resilience, social support, positive affect and posttraumatic growth among Chinese women with infertility, and to examine the mediating role of positive affect. A convenience sample of 1733 women diagnosed with infertility was recruited from the infertility outpatient clinics at three reproductive hospitals in Shandong Province of China between May 2015 and April 2016. They completed a background questionnaire, the Posttraumatic Growth Inventory, the Perceived Social Support Questionnaire, the Connor-Davidson Resilience Scale, the Positive and Negative Affect Schedule. Individuals reported high levels of PTG (M = 64.81; SD = 16.20). Perceived social support (β = .11, p < .001), resilience (β = .18, p < .001) and positive affect (β = .46, p < .001) were related to PTG. Positive affect may play a mediating role in the relationships between resilience (.125, .201, p < .001), social support (.055, .121, p < .001) and PTG. This study examines the effects of resilience, social support, and positive affect on PTG among Chinese infertile women. Wherein, positive affect may play a mediating role in the relationships between resilience, social support and PTG. 相似文献

The effect of normal aging on lexical production and semantic processing was evaluated in 72 healthy participants. Four tasks were used, picture naming (PN), picture categorization (PC), numerical judgment (NJ), and color judgment (CJ). The dependence of reaction time (RT) and correct responses with age was accounted by mixed-effects models. Participants underwent neuropsychological testing for verbal, executive, and memory functions. The RTs increase significantly with age for all tasks. After parceling out the non-specific cognitive decline, as reflected by the NJ task, the RT for the PN task decreases with age. Behavioral data were interpreted in relation with neuropsychological scores. Our results suggest that (a) naming becomes more automatic and semantic processing slightly more difficult with age, and (b) a non-specific general slowdown of cognitive processing occurs with age. Lexical production remained unaltered, based on compensatory automatic processes. This study also suggests a possible slowdown of semantic processing, even in normal aging. 相似文献

Recent research has shown that over-extraction of latent classes can be observed in the Bayesian estimation of the mixed Rasch model when the distribution of ability is non-normal. This study examined the effect of non-normal ability distributions on the number of latent classes in the mixed Rasch model when estimated with maximum likelihood estimation methods (conditional, marginal, and joint). Three information criteria fit indices (Akaike information criterion, Bayesian information criterion, and sample size adjusted BIC) were used in a simulation study and an empirical study. Findings of this study showed that the spurious latent class problem was observed with marginal maximum likelihood and joint maximum likelihood estimations. However, conditional maximum likelihood estimation showed no overextraction problem with non-normal ability distributions. 相似文献

Pursuing the line of the difference models in IRT (Thissen &; Steinberg, 1986), this article proposed a new cognitive diagnostic model for graded/polytomous data based on the deterministic input, noisy, and gate (Haertel, 1989; Junker &; Sijtsma, 2001), which is named the DINA model for graded data (DINA-GD). We investigated the performance of a full Bayesian estimation of the proposed model. In the simulation, the classification accuracy and item recovery for the DINA-GD model were investigated. The results indicated that the proposed model had acceptable examinees' correct attribute classification rate and item parameter recovery. In addition, a real-data example was used to illustrate the application of this new model with the graded data or polytomously scored items. 相似文献

Three studies were conducted to investigate if children think that physical growth is determined by inheritance. All three studies employed the “switched‐at‐birth” task. Study 1 investigated if children and adults thought that height and weight were determined by parentage. Study 2 examined preschoolers and elementary school children's and adults' understanding of the role of parentage and nutrition in determining weight. Study 2a examined children's and adults' understanding of the role of parentage and nutrition in determining height. Results indicate that overall, preschoolers and third graders have more of an inheritance bias for height than for weight. However, when nutrition was introduced, apart from third graders, all other grades reasoned that nutrition played a greater role in determining weight. Overall, these results indicate that even young children have a rudimentary but differentiated theory of the role of inheritance in determining height and weight.
Highlights
- Participants were presented with switched‐at‐birth tasks to determine if they thought that parentage and/or nutrition influences height and weight.
- Young children viewed height as determined more by parentage than weight, suggesting that they have a differentiated and autonomous theory for the determination of height.

Strong disagreements have stymied today’s political discourse. We investigate intellectual humility – recognizing the limits of one’s knowledge and appreciating others’ intellectual strengths – as one factor that can make disagreements more constructive. In Studies 1 and 2, participants with higher intellectual humility were more open to learning about the opposition’s views during imagined disagreements. In Study 3, those with higher intellectual humility exposed themselves to a greater proportion of opposing political perspectives. In Study 4, making salient a growth mindset of intelligence boosted intellectual humility, and, in turn, openness to opposing views. Results suggest that intellectual humility is associated with openness during disagreement, and that a growth mindset of intelligence may increase intellectual humility. Implications for current political polarization are discussed. 相似文献

Constructive communication is an important correlate to examine for sexual health promotion and HIV prevention among male couples. However, few studies have examined the effect of different relationship dynamics on both partners' perceptions of constructive communication. Using dyadic data collected from 361 male couples, the present authors explore which relationship dynamics were associated with constructive communication patterns. The results highlight the relevance of investment in a sexual agreement and trust within the relationship in perceptions of constructive communication. These findings may be particularly useful to guide the development of future dyadic-focused sexual health and HIV preventive interventions for male couples. 相似文献

This data linkage study aims to examine associations between subgroups of child maltreatment and a range of demographic (e.g., gender) familial (e.g., parental unemployment) and health outcomes. Structured interviews were conducted on 2,980 participants. Data were then linked with information drawn from Danish registries. Multinomial logistic regression analyses indicated out-of-home-care was a shared risk for all forms of maltreatment relative to nonmaltreated controls. Sexual and co-occurring abuse groups had strong associations with psychiatric outcomes at age 21. Findings emphasize how a child’s early environment can impact health, highlighting the need for targeted interventions encompassing a range of risk factors at an early age. 相似文献

Social learning has been shown to be an evolutionarily adaptive strategy, but it can be implemented via many different cognitive mechanisms. The adaptive advantage of social learning depends crucially on the ability of each learner to obtain relevant and accurate information from informants. The source of informants’ knowledge is a particularly important cue for evaluating advice from multiple informants; if the informants share the source of their information or have obtained their information from each other, then their testimony is statistically dependent and may be less reliable than testimony from informants who do not share information. In this study, we use a Bayesian model to determine how rational learners should incorporate the effects of shared information when learning from other people, conducting three experiments that examine whether human learners behave similarly. We find that people are sensitive to a number of different patterns of dependency, supporting the use of a sophisticated strategy for social learning that goes beyond copying the majority, and broadening the situations in which social learning is likely to be an adaptive strategy. 相似文献
