This study examined whether the effects of stereotype threat on memory and subjective age were moderated by positive age stereotypes and self-perceptions of aging among older adults. Perceived threat as a mechanism underlying these effects was also explored. Results showed that stereotype threat (high vs. low threat) did not affect the dependent variables. Moreover, self-perceptions of aging did not moderate the effect of stereotype threat on the dependent variables. However, for people with more positive age stereotypes, older people under highthreat perceived more threat than people under low threat. This could be explained by an effect of age stereotypes in the high-threat group: the more positive age stereotypes held by participants, the more they perceived threat, which in turn decreased their memory performance and made them feel mentally older. We hypothesized that age group identity is stronger in people with more positive age stereotypes, which increase perceived threat.  相似文献

Consumers tend to relate to brands in similar ways as they relate to individuals and groups. However, relatively little is known about the attribution of human traits to brands in online contexts. The current research focused on the role of attributed brand traits in interactive corporate social responsibility (CSR) communication and positive electronic word‐of‐mouth intentions. Results of an online survey (N = 174) revealed that higher levels of perceived interactivity were associated with stronger attributions of morality, sociability, and competence traits to brands. Yet only attributed brand morality was associated with consumers' willingness to endorse the brand and its CSR message on social networking sites. These findings underline the importance of brands' openness to dialogue regarding the promotion of CSR activities. Furthermore, these findings suggest that consumers are most likely to feel that brands can represent their identity when brand morality is considered to be high.  相似文献

Parents can influence their children’s problematic mobile phone involvement (PMPI) by engaging in parental mediation activities, such as restrictions or co-use, by being a role model, and by their general and domain-unspecific parenting style that facilitates more or less attachment security of the child. This study tested the associations between these different routes of influence—parental mediation of the mobile phone, parental PMPI, and secure child-parent attachment—with children’s PMPI. Data was acquired from a quota-sample survey with 500 children, between 8 and 14 years of age, and one of their parents. Results point to the importance of open and empathic parent-child-communication, as well as a positive relationship quality, and demonstrate the detrimental effects of parents’ own PMPI on children’s PMPI.  相似文献

Background/ObjectiveDepressive disorders have a high prevalence around the world. They present a great comorbidity with other disorders like anxiety, thereby making a differential diagnosis very difficult. The Basic Depression Questionnaire was designed to palliate this issue by isolating specific depression symptoms. Our aim is to study the reliability, factorial structure, and differential item functioning of this questionnaire. Method: The sample consisted of 1,397 adults without psychological problems (Mage = 29.76, SD = 11.25, 64.78% women) who completed the CBD. Results: We observed that none of the items presented differential functioning. A monofactorial structure was established. In this model a good fit was obtained by confirmatory factor analysis and a strict invariance by sex. The ordinal alpha was used to check the reliability and it fetched an index of .95. Conclusions: The Basic Depression Questionnaire has adequate psychometric properties. The absence of differential item functioning and the invariance by sex are guarantees of an adequate use to diagnose depression for men and women. So, its clinical use can help to differentiate between the specific diagnoses for depressive disorders and anxiety disorders.  相似文献

Research on factors associated with poor adherence to self-care focuses primarily on psychiatric emotional disorders such as depression and anxiety, whereas non-psychiatric chronic-disease-related emotional distress has received little attention in hypertensive patients. The objective of this study was to evaluate the association of hypertension-related distress with the lack of self-care including low adherence to pharmacological treatment, lack of regular physical activity, low intake of fruits and vegetables and frequent intake of high-salt foods. A cross-sectional survey was conducted in 2014 in two family medical units affiliated with the Mexican Institute of Social Security. The study included 487 hypertensive patients >19 years of age. The conceptual framework for the study was based on the Health Promotion Model. The analysis included multiple Poisson regression models. We found that 21.1% of participants had hypertension-related distress. Low adherence to pharmacological treatment was identified in 45.8% of patients, whereas 46.8% lacked regular physical activity, 30.8% reported a low consumption of fruits and vegetables, and 54.6% frequently consumed foods high in salt content. Hypertension-related distress was associated with lack of regular physical activity and low intake of fruits and vegetables. These findings highlight the importance of addressing distress in order to improve self-care of hypertensive patients.  相似文献

Comparative analysis of the gestural communication of our nearest animal relatives, the great apes, implies that humans should have the biological potential to produce and understand 60–70 gestures, by virtue of shared common descent. These gestures are used intentionally in apes to convey separate requests, rather than as referential items in syntactically structured signals. At present, no such legacy of shared gesture has been described in humans. We suggest that the fate of “ape gestures” in modern human communication is relevant to the debate regarding the evolution of language through a possible intermediate stage of gestural protolanguage.  相似文献
