We describe briefly the redevelopment of Space Fortress (SF), a research tool widely used to study training of complex tasks
involving both cognitive and motor skills, to be executed on currentgeneration systems with significantly extended capabilities,
and then compare the performance of human participants on an original PC version of Space Fortress (SF) with the revised Space
Fortress (RSF). Participants trained on SF or RSF for 10 sets of eight 3-min practice trials and two 3-min test trials. They
then took tests involving retention, resistance to secondary task interference, and transfer to a different control system.
They then switched from SF to RSF or from RSF to SF for 2 sets of final tests and completed rating scales comparing RSF and
SF. Slight differences were predicted on the basis of a scoring error in the original version of SF used and on slightly more
precise joystick control in RSF. The predictions were supported. The SF group started better but did worse when they transferred
to RSF. Despite the disadvantage of having to be cautious in generalizing from RSF to SF, we conclude that RSF has many advantages,
which include accommodating new PC hardware and new training techniques. A monograph that presents the methodology used in
creating RSF, details on its performance and validation, and directions on how to download free copies of the system may be

Drawing on the family stress process model and using data from 141 same-sex couples (N = 282 partners), we examined associations between heterosexist discrimination and relational sacrifices (i.e., willingness and behaviors). We also examined the moderating roles of both partners' internalized homophobia and state-level liberalism on same-sex marriage legalization. Actor-partner interdependence moderation models were conducted. Most of our findings supported hypotheses from the family stress process model. One individual's experiences of greater heterosexist discrimination were related to the partner's higher levels of sacrifice willingness and the individual's own higher frequency of sacrifice behaviors. Such associations emerged (a) among couples living in more liberal states that legalized same-sex marriage earlier, and (b) when the individual's partner reported lower levels of internalized homophobia. Yet the moderating role of an individual's internalized homophobia was the opposite of our hypothesis. When individuals reported high (versus low) internalized homophobia, individuals' experiences of more discriminative events were related to partners' higher levels of sacrifice willingness. Collectively, our study findings highlight that—when investigating how same-sex couples forge and maintain romantic bonds—researchers should consider their experiences in the social cultural context of heteronormativity, which includes the focus on discrimination, stigma, and affirmative laws and policies. 相似文献
We provide reporting guidelines for multilevel factor analysis (MFA) and use these guidelines to systematically review 72 MFA applications in journals across a range of disciplines (e.g., education, health/nursing, management, and psychology) published between 1994 and 2014. Results are organized in terms of the (a) characteristics of the MFA application (e.g., construct measured), (b) purpose (e.g., measurement validation), (c) data source (e.g., number of cases at Level 1 and Level 2), (d) statistical approach (e.g., maximum likelihood), and (e) results reported (e.g., intraclass correlations for indicators and latent variables, standardized factor loadings, fit indices). Results from this review have implications for applied researchers interested in expanding their approaches to psychometric analyses and construct validation within a multilevel framework and for methodologists using Monte Carlo methods to explore technical and methodological issues grounded in realistic research design conditions. 相似文献
A proportion of persons affected by coronavirus disease-19 (COVID-19) die and do so in extraordinary circumstances. This can make grief management extremely challenging for families. The Clinical Psychology unit of an Italian hospital offered a bereavement follow-up call to such families. This study aimed to explore the families' experiences and needs collected during these calls, and the role that the psychologists played through the call. A total of 246 families were called over 3 months. Multiple qualitative methods included: (i) written reports of the calls with relatives of patients who died at the hospital for COVID-19; (ii) qualitative semi-structured interviews with psychologists involved in the calls; (iii) observation of psychologists' peer group discussions. A thematic analysis was conducted. Six themes emerged: without death rituals, solitary, unexpected, unfair, unsafe, coexisting with other stressors. Families' reactions were perceived by psychologists as close to a traumatic grief. Families' needs ranged from finding alternative rituals to giving meaning and expressing different emotions. The psychologists played both a social-institutional and a psychological-human role through the calls (e.g., they cured disrupted communication or validated feelings and choices). This study highlighted the potential of traumatic grief of families of COVID-19 victims, and provided indications for supporting them within the space of a short phone call. 相似文献
Low family socioeconomic status (SES) is linked with adolescents’ symptoms of depression, but little is known about the mediating and moderating mechanisms underlying this association. Based on ecosystem theory and the organism-environment interaction model, we tested whether emotional resilience mediated the relationship between family SES and depressive symptoms, and whether parent–child relationship quality moderated the relationship. Adolescents (N?=?724) from one middle school in central China completed self-reported questionnaires regarding demographic variables, family SES, emotional resilience, parent–child relationship quality, and depressive symptoms. Regression-based mediation analysis indicated that emotional resilience mediated the association between family SES and depressive symptoms. Parent–child relationship quality moderated two components of this mediation process, namely the effects of low SES on both emotional resilience and depressive symptoms. In both cases, a high quality parent–child relationship ameliorated the adverse effects of low family SES. That is, adolescents with a higher quality relationship with their parent appeared to be less affected by low family SES. The study reveals how and when family SES may affect adolescents’ depressive symptoms, and highlights the protective effect of a high quality parent–child relationship in a low SES environment.
To address widespread perceptions of a reproducibility crisis in the social sciences, a growing number of scholars recommend the systematic preregistration of empirical studies. The purpose of this article is to contribute to an epistemological dialogue on the value of preregistration in consumer research by identifying the limitations, drawbacks, and potential adverse effects of a preregistration system. After a brief review of some of the implementation challenges that commonly arise with preregistration, we raise three levels of issues with a system of preregistration. First, we identify its limitations as a means of advancing consumer knowledge, thus questioning the sufficiency of preregistration in promoting good consumer science. Second, we elaborate on why consumer science can progress even in the absence of preregistration, thereby also questioning the necessity of preregistration in promoting good consumer science. Third, we discuss serious potential adverse effects of preregistration, both at the individual researcher level and at the level of the field as a whole. We conclude by offering a broader perspective on the narrower role that preregistration can play within the general pursuit of building robust and useful knowledge about consumers. 相似文献
