Based on the Eccles’ expectancy-value theory, the objectives of this study were (1) to examine the longitudinal relations between Latino parents’ science beliefs, parents’ science support, and high school students’ science motivational beliefs, and (2) to test whether these relations varied by familism values and adolescent gender. Multi-informant longitudinal survey data were collected from 104 Latino parents and adolescents during 9th and 10th grade. Parents’ perceptions of their adolescents’ science ability and value of science in 9th grade predicted higher parent science support at home in 10th grade if they were parents of boys. In contrast, these relations were not statistically significant for parents of daughters. Parent support in 9th grade predicted higher adolescent motivational beliefs one year later. This work provides evidence that parent support is important for high school student success in this understudied population.  相似文献

Scholars have paid an increasing amount of attention to organizational citizenship behaviors (OCBs), with a particular emphasis on helping others at work. In addition, recent empirical work has focused on how OCB is an intraindividual phenomenon, such that employees vary daily in the extent to which they help others. However, one limitation of this research has been an overemphasis on well‐being consequences associated with daily helping (e.g., changes in affect and mental depletion) and far less attention on behavioral outcomes. In this study, we develop a self‐regulatory framework that articulates how helping others at work is a depleting experience that can lead to a reduction in subsequent acts of helping others, and an increase in behaviors aimed at helping oneself (i.e., engaging in political acts). We further theorize how two individual differences—prevention focus and political skill—serve as cross‐level moderators of these relations. In an experience sampling study of 91 full‐time employees across 10 consecutive workdays, our results illustrate that helping is a depleting act that makes individuals more likely to engage in self‐serving acts and less likely to help others. Moreover, the relation of helping acts with depletion is strengthened for employees who have higher levels of prevention focus.  相似文献

Online mental health services provide a point-of-access to mental healthcare that may otherwise be unavailable or limited, particularly in developing countries. Nevertheless, there is a lack of research into individual differences between those who prefer online mental health services and those who prefer traditional in-person services, and whether these differences vary as a function of culture. This study investigated differences in preferences for online or in-person mental health services on e-health literacy, age, education level, and comfort using the internet in a general community sample recruited from Australia and India. A total of 487 participants (31.6% male; mean age?=?33.55, SD?=?12.20, range 18–78), 297 Australians and 190 Indians, completed an online or paper-and-pencil survey. A significant negative relationship between age and e-health literacy was found with younger ages associated with higher e-health literacy. Furthermore, e-health literacy scores were significantly higher for the Australian sample. Age, e-health literacy, country-of-residence, education level, and comfort in using the internet did not predict mental health service preference. The results suggest that preference for in-person or online mental healthcare is independent of demographic and cultural factors and indicate that online mental health services may be acceptable to Indian health service consumers.  相似文献

When an automobile driver overtakes a lead vehicle while avoiding oncoming traffic, does he or she do so with reference to the limits of his or her car? We investigated overtaking from the perspective of the theory of affordances. We define the overtake-ability affordance as a ratio of the minimum satisfying velocity required for safe overtaking (MSV) to the maximum velocity of the driver's car (Vmax). Two groups of participants performed overtaking maneuvers, if deemed possible, by driving either a slow (Vmax = 25 m/s) or a fast (Vmax = 32.5 m/s) virtual car in overtaking situations constrained by 14 values of MSV. For any given MSV condition, participants in the fast car group were more likely to attempt an overtaking maneuver. However, when MSV was expressed in intrinsic units as a ratio of Vmax for both groups, the frequency of overtaking was not significantly different across groups. Furthermore, overtaking frequency dropped to near 0% for both groups when MSV exceeded Vmax. In accordance with the affordance-based framework (Fajen, 2007), our results suggest that participants select their overtaking maneuvers by perceiving an overtake-ability affordance.  相似文献

Does adherence to Islam predict attitudes about “suicide bombing” among American Muslims? This study examines the effects of religious and political factors on views of politically motivated violence (PMV). We draw from diverse scholarship, emphasizing arguments that are inspired by Samuel Huntington's Clash of Civilizations perspective, as well as recent work in the sociology of Islam. Using a measure that gauges support for “suicide bombing” from the 2007 Pew Survey of American Muslims, results from logistic regression models suggest that political views and religious factors have a minimal effect on Muslim American attitudes toward suicide bombing. Furthermore, we find that Qur’ānic authoritativeness (i.e., the view that the Qur’ān is the word of God and not written by men) is associated with lower odds of supporting this form of PMV. We discuss the implications of our findings for the often anecdotal and alarmist accounts that link Muslim religiosity to support for “radical” extremism. We close with study limitations and avenues of future research.  相似文献

Context variability can be defined as the number of preexperimental contexts in which a given concept appears. Following M. Steyvers and K. J. Malmberg's (2003) work, the authors have shown that concepts that are experienced in fewer preexperimental contexts generally are better remembered in episodic memory tasks than concepts that are experienced in a greater number of preexperimental contexts. The purpose of this article is to demonstrate that low context variability confers its memorial advantage because of stronger item-to-list context associations as compared with high context variability. Three experiments that use environmental context changes from study to test demonstrate that the low context variability advantage is eliminated when item-to-list context associations are not available because of environmental changes at test. In addition, the low context variability advantage is eliminated when inward processing at study prevents the formation of item-to-list context associations.  相似文献

The correlation between depression and dysfunctional marital interaction is well documented, but only a few studies have examined gender-related differences in marital interaction patterns of couples with a depressed partner. In this paper we examined differences in observed marital communication in a sample of 62 Swiss couples presenting for treatment of depression. There were 16 maritally distressed couples with a depressed wife, 21 maritally nondistressed couples with a depressed wife, 18 maritally distressed couples with a depressed husband, and 7 maritally nondistressed couples with a depressed husband. Marital interaction behavior was found to depend on gender, depression, marital distress, as well as gender of the depressed partner. Our results suggest the need for a gender-sensitive model of the link between marital interaction and depression.  相似文献
