Interest in nostalgia has blossomed, yet its nature in older adulthood and potential for intergenerational transfer to younger adults has remained neglected. In Experiment 1, we focused on the content of older adults’ nostalgic (vs. ordinary) recollections and asked whether older adults’ nostalgia could be transferred to younger adults. We showed that nostalgia expressed in older adults’ narratives was positively associated with nostalgia reported by young-adult readers. In Experiment 2, undergraduates read a nostalgic or ordinary narrative written by an older adult. Then they rated their own nostalgia as well as their perceived social connectedness, self-continuity, and meaning in life. Exposure to older adults’ nostalgic (vs. ordinary) narratives promoted concurrent nostalgia among young adults, along with associated psychological benefits (social connectedness, self-continuity, meaning). The findings illustrate the potential for intergenerational transfer of nostalgia through written narratives, and attest to the universality of nostalgic themes across younger and older adults.  相似文献

The popularity of remote work continues to rise, but uncertainty remains about how it influences employee well-being. We extend the Demand-Control-Person (DCP) model to test both person and job factors as important considerations in remote work, suggesting that emotional stability influences the utility of autonomy as a job resource in protecting employees from strain. Additionally, we test self-determination theory (SDT), positioning need satisfaction for autonomy, relatedness, and competence as mechanisms explaining the relationship between remote work and strain. In two field studies, high–emotional stability employees reporting high levels of autonomy experienced the lowest levels of strain, with negative relationships between extent of remote work and strain. In contrast, low–emotional stability employees who also have high autonomy appear more susceptible to strain, and this may increase when they work remotely more often. Our multilevel structural equation modelling revealed that high–emotional stability employees with high autonomy appear best positioned to meet their needs for autonomy and relatedness, even when remote work is more frequent; these in turn reduced the likelihood of strain. Thus, our results support the DCP and SDT models, revealing theoretical and practical implications for designing and managing remote work arrangements.  相似文献

The classic Aesop’s fable, Crow and the Pitcher, has inspired a major line of research in comparative cognition. Over the past several years, five articles (over 32 experiments) have examined the ability of corvids (e.g., rooks, crows, and jays) to complete lab-based analogs of this fable, by requiring them to drop stones and other objects into tubes of water to retrieve a floating worm (Bird and Emery in Curr Biol 19:1–5, 2009b; Cheke et al. in Anim Cogn 14:441–455, 2011; Jelbert et al. in PLoS One 3:e92895, 2014; Logan et al. in PLoS One 7:e103049, 2014; Taylor et al. in Gray R D 12:e26887, 2011). These researchers have stressed the unique potential of this paradigm for understanding causal reasoning in corvids. Ghirlanda and Lind (Anim Behav 123:239–247, 2017) re-evaluated trial-level data from these studies and concluded that initial preferences for functional objects, combined with trial-and-error learning, may account for subjects’ performance on key variants of the paradigm. In the present paper, we use meta-analytic techniques to provide more precise information about the rate and mode of learning that occurs within and across tasks. Within tasks, subjects learned from successful (but not unsuccessful) actions, indicating that higher-order reasoning about phenomena such as mass, volume, and displacement is unlikely to be involved. Furthermore, subjects did not transfer information learned in one task to subsequent tasks, suggesting that corvids do not engage with these tasks as variants of the same problem (i.e., how to generate water displacement to retrieve a floating worm). Our methodological analysis and empirical findings raise the question: Can Aesop’s fable studies distinguish between trial-and-error learning and/or higher-order causal reasoning? We conclude they cannot.  相似文献

Inclusion of children in medical decision making, to the extent of their ability and interest in doing so, should be the default position, ensuring that children are routinely given a voice. However, optimizing the involvement of children in their health care decisions remains challenging for clinicians. Missing from the literature is a stepwise approach to assessing when and how a child should be included in medical decision making. We propose a systematic approach for doing so, and we apply this approach in a discussion of two challenging clinical cases. The approach is informed by a literature review, and is anchored by case studies of teenagers' refusal of clinical care, regulatory requirements for research assent, and the accepted approach to involving cognitively impaired adults in medical decisions.  相似文献

Recent research has described the structure of psychopathology as including one general and multiple specific factors, and this structure has been found in samples across development. However, little work has examined whether this structure is consistent across time, particularly in young children, within the same sample. Further, few studies have examined factors that influence the magnitude of the stability of latent dimensions of psychopathology. In the present study, we examine these issues in a community sample of 545 children assessed at ages 3 and 6. In addition, we explored child temperament, parental history of psychopathology, and parenting behaviors as potential moderators of the longitudinal stability of latent dimensions of psychopathology. We found that the same bifactor model structure identified at age 3 provided an adequate fit to the data at age 6. Further, our model revealed significant homotypic stability of the general, internalizing, and externalizing specific factors. We also found evidence of differentiation of psychopathology over time with the general factor at age 3 predicting the externalizing factor at age 6. However, we failed to identify moderators of the longitudinal associations between psychopathology latent factors. Overall, our results bolster support for the bifactor structure of psychopathology, particularly in early childhood.  相似文献

Tolerating or condoning practices that one finds objectionable is typically considered a positive way to negotiate intergroup differences. However, being the target of tolerance might harm well-being, which we examined in three studies (a survey and two experiments) among a total of 1,054 members of various racial/ethnic minority groups in the United States. In Study 1, we found that perceiving oneself to be tolerated on the basis of one’s ethnic group membership was associated with more negative well-being. In Study 2, we found that bringing to mind experiences of being tolerated results in less positive and more negative affect than thinking about experiences of acceptance, but more positive and less negative outcomes than thinking about overt discrimination experiences. In Study 3, we replicated the results of Study 2 while demonstrating that threat to social identity needs mediates the tolerance–well-being link. These results suggest that being tolerated is related to minority targets’ well-being in ways that are intermediate between being treated with outright discrimination and full acceptance, but that being tolerated follows a pattern closer to discrimination.  相似文献

Research suggests that parent–child conflict is a salient family process in Asian immigrant families and often a stressful experience for Asian American youth due to value discrepancies between Asian and Western cultures. The present study examined ratings of parent–child conflict across conflict topics from parents' and children's perspectives in a sample of Chinese American immigrant families with school‐age children (N = 239; age = 7.5–11 years). Latent profile analyses identified three parent‐rated conflict profiles and four child‐rated conflict profiles. Parent and child conflict profiles were unrelated to each other and differentially related to family sociocultural factors and children's psychological adjustment. Parents' moderate conflict profile scored highest on parent‐rated child behavior problems and had the highest household density and lower parent Chinese orientation. Children's moderate‐specific and high conflict profiles scored higher on child‐reported behavior problems than the low conflict profile. These results highlight the need to assess family conflict from both parents' and children's perspectives and target parent–child conflict communication as a pathway to prevent or reduce behavioral problems in Chinese American children of immigrant families.  相似文献

Several studies have observed heightened Pavlovian fear conditioning in PTSD. However, it is unclear how fear conditioning in PTSD is related to risk factors for the disorder, such as anxiety sensitivity. Fifty-one combat-exposed veterans (20 with PTSD, 31 without PTSD) completed a differential fear conditioning task in which one colored rectangle (CS +) predicted a loud scream (US), whereas a different colored rectangle (CS-) predicted no US. Veterans with PTSD were characterized by greater anxiety to the CS + but not the CS- during acquisition and extinction, and greater US expectancy during the CS + but not the CS- at extinction. Also, veterans with PTSD had greater pupil dilation to both CSs at extinction, but not at acquisition. Anxiety sensitivity was correlated with anxiety and US expectancy in response to the CS +, but not the CS-, at both acquisition and extinction, and also with pupil diameter to both the CS + and CS- at extinction. Nearly all of these relations held when covarying for PTSD symptoms and trait anxiety. These findings suggest that increased fear conditioning in PTSD may be related to elevated anxiety sensitivity.  相似文献

The progressive increase in life expectancy and the verticalization of the family mean that the provision of family care can be stressful and risky for the health of grandmothers who act as caregivers. One hundred and twenty grandmothers were interviewed in southwest Spain; they were daughters of a generation still characterized by high levels of dependence. A questionnaire with standardized psychological scales and items specifically designed for the study was used. Results showed that the burden of the instrumental and economic support had a detrimental effect on their health through stress, which in turn increased when they used coping strategies of denial and self-blame, and decreased with acceptance of reality and when they sought emotional support.  相似文献
