A recent re-operationalisation of grandiose narcissism has resulted in the distinction of two narcissistic strategies based on the cognitive, affective-motivational and behavioural dynamics: admiration (assertive self-enhancement) and rivalry (antagonistic self-protection). The Narcissistic Admiration and Rivalry Questionnaire (NARQ) was developed to assess this model with two higher-order dimensions. However, cross-validations of the NARQ have not been extensively conducted across diverse population groups and languages. This study aimed to test the internal and external validity (through the relation with envy and self-esteem), reliability and cross-cultural equivalence of the Spanish version of the NARQ. The psychometric properties were evaluated in a Spanish sample (N = 310), and cross-cultural equivalence was tested in participants from Chile (N = 234) and Colombia (N = 256). The results supported the reliability and validity of the Spanish NARQ, as well as the cross-cultural equivalence across Spanish-speaking countries. In addition, we discuss obtained differences across Spanish, Chilean and Colombian sample within two narcissistic strategies.  相似文献

Using data from a longitudinal study, the present study employed a latent class mover-stayer analytical strategy to examine both the cross-sectional and longitudinal (+33 months) relationship between membership of stress classes, and subjective life expectancy. Participants were from 21 High schools in Scotland and Northern Ireland. Data were collected in the first year of High school (mean age = 12.5 years), and at +33 months (fourth year, or school year 11). Sample 1 consisted of 1171 adolescents (40.82% females, 2.56% unreported) in Northern Ireland. Sample 2 consisted of 1059 adolescents (52.79% females, 1.32% unreported) in Scotland. Adolescents with the lowest levels of stress projected the highest subjective life expectancy scores. Longitudinal analyses were jumbled and not in keeping with cross-sectional results. More research may be needed on the trajectory of subjective life expectancy over time before it can be depended upon as a reliable outcome variable in adolescent development.  相似文献

Founded and led by a U.S.-born white pastor, Amor Poderoso is a nondenominational, evangelical megachurch in El Paso, Texas, almost entirely composed of Mexican-Americans, recent Mexican immigrants, and current Mexican citizens. Ethnographic fieldwork from 2014 to 2017, supplemented with interviews with pastors, worship leaders, and attendees, reveal that much of congregational life orients around intentionally showcasing “Mexican” culture through sounds, images, and artifacts that appropriate an array of idealized ethnic references (e.g., food, dress, mannerisms, clichés) from Northern Mexico. Ongoing ethnic displays do not originate spontaneously or impromptu from membership but rather serve as a form of tactical authenticity derived from U.S. racial schemas mobilized by congregational leaders as a distinctive religious resource. Weekly worship services featuring dialect-inflected Spanish preaching and singing project ethnic signals that elicit connections to both a common ancestral heritage and a common religious identity. In short, church leaders at this southern border Latino church deliberately deploy sounds, images, and artifacts to assert racialized performances of being “Mexican” for distinctly religious purposes, especially evangelization. In the process, the distinctive practices of religious racialization effectively structure church members’ ethnic and religious identities around racial tropes to buttress a cogent corporate identity for enacting institutionalized evangelical narratives and legitimating charismatic authority.  相似文献

Studies have shown that the multiple-stimulus without replacement (MSWO) preference assessment is an effective assessment format for identifying preferred items. However, it is possible that factors other than reinforcer quality might influence selections by some individuals when the MSWO array consists of edible items. The validity of the MSWO results was evaluated by comparing items identified as most and least preferred by the MSWO assessment in a concurrent-schedule (CS) format. Varying edible items were used in each study. The MSWO format accurately identified the higher quality edible item for most participants across studies (76%); however, the MSWO format did not predict the highest quality edible item in the CS assessment for 20% to 30% of participants in each study.  相似文献

Children with autism spectrum disorder (ASD) who have limited speech are often taught to communicate using a speech-generating device (SGD). We evaluated procedures for teaching a mand for information (i.e., Where is [item]?) using an interrupted behavior chain procedure. In Experiment 1, all participants (3 children with ASD who communicated using an SGD) acquired the target mand but transfer to a novel stimulus did not occur. In the second experiment, 2 participants were taught to approach alternative communication partners when the first partner did not provide the information. The second experiment also included procedures to test whether the responses were under the control of appropriate motivating operations (MOs). Generalization across communication partners occurred with both participants, but transfer across behavior chains with only 1 participant. The results of both experiments suggest that teaching multiple behavior chains and evaluating MO control may be necessary to establish generalized manding for information.  相似文献

Creativity is an understudied topic in elementary school mathematics research. Nevertheless, we argue that creativity plays an important role in mathematics, but that more research is needed to understand this relation. Therefore, this study aimed to investigate this relation, specifically between domain-general creativity, domain-specific mathematical creativity, and mathematical ability. Measures for these constructs were administered to 342 Dutch fourth graders. In order to examine the nature of the relation between creativity and mathematics, two competing models were tested, using Structural Equation Modeling. The results indicated that models in which general creativity and mathematical ability both predict mathematical creativity fitted the data better than models in which mathematical and general creativity predict mathematical ability. This study showed that both general creativity and mathematical ability are important to think creatively in mathematics.  相似文献

Habit reversal training (HRT) has been a mainstay of behavior analysts' repertoire for nearly the last 50 years. HRT has been effective in treating a host of repetitive behavior problems. In the face of the current coronavirus pandemic, HRT has practical public health importance as a possible intervention for reducing hand-to-head behaviors that increase the risk of viral infection. The current paper provides a brief review of HRT for hand-to-head habits that is designed for a broad audience and concludes with practical suggestions, based on HRT, for reducing face-touching behaviors.  相似文献

Two experiments evaluated whether rats' occupancy of a restraint tube is reinforcing. In Experiment 1, each rat in the 0-min group moved freely in a chamber where a wall blocked access to a restraint tube. After 10 min the wall was removed, permitting 15 min of chamber access and tube entry. The other 2 groups were locked in the tube for 10 and 20 min respectively before release into the chamber for 15 min. Across sessions, rats locked up for 10 and 20 min entered the tube more frequently than rats in the 0-min group, and during the first 2 sessions rats in the 20-min group stayed in the tube longer than the other groups. Over sessions this difference disappeared. However, for all groups and sessions the mean percentage of session time in the tube exceeded chance expectations. This result suggests tube occupation was reinforcing. In Experiment 2’s Phase 1, rats could enter an open tube. On exiting, the tube door closed. A lever press opened the door for the rest of the 1-hr session. In Phase 2, these rats were locked in the tube for 10 min before the door opened. Upon exiting, the door closed. As in Phase 1, a lever press opened the door for the rest of the session. The latency between pressing and tube entry decreased over sessions, indicating that tube entry reinforced lever pressing. These results are difficult to reconcile with accounts of rat empathy based on the thesis that tube restraint distresses occupants.  相似文献

The present work investigates the endorsement, antecedents, relationships, and consequences of young immigrants’ social identities in Norway. Despite increasing numbers of refugees and immigrants entering Norway in recent years, little is known about the relationship between immigrants’ different social identities and their feeling of integration into Norwegian society. The main goal of the present research is to fill this gap by investigating whether relationships found in other European countries replicate in the Norwegian context. In line with theoretical considerations and earlier international findings, results from two studies with different immigrant groups (Study 1: high school students; N = 97; Study 2: university students; N = 93) show that the more young immigrants in Norway endorse their national (i.e., Norwegian) identity, the less they endorse their ethnic identity (e.g., Kurdish). We further show that perceived conflict between the two cultures cannot explain the negative relationship between national and ethnic identity. In addition, immigrants’ national identity endorsement is positively related to their dual identity endorsement (e.g., Kurdish-Norwegian). Positive contact with members of the receiving society predicts young immigrants’ feeling of being integrated in Norwegian society and this relationship is mediated by national identity. Results are discussed in terms of the crucial role social identities play in immigrants’ feeling of integration into European societies.  相似文献
