The current study examines parents’ reactions to making social comparisons of their children on school-related domains. Parents (N = 117; ages 25 to 49; 94% women) of elementary school-age children (ages 5 to 10; 57.3% girls) were recruited online from Facebook parenting groups and several school districts in Atlantic Canada. Participants were randomly assigned to make either an upward, a downward, or a lateral social comparison about their child’s ability in school. Participants reported the time since the event in comparison, their emotional reactions, their evaluations of their child’s ability in the domain, and how important they perceived the domain to be for their child’s future. Domain importance and evaluations of the child’s abilities also were measured prior to making the comparison. Significant differences based on social comparison condition were found for temporal distance, post-comparison domain importance, and post-comparison assessments of the child’s ability in the domain. The effect of social comparison on post-comparison domain importance was not mediated by post-comparison assessments of the child’s ability, suggesting a direct effect of comparisons on perceived domain importance. These findings suggest that the act of social comparison caused parents to reevaluate the importance of the domain of comparison and their child’s abilities in that domain. Implications for parents and educators are discussed.  相似文献

Although significant strides have been made for sexual and gender minority (SGM) rights in the United States, there continues to be opposition to SGM rights from many conservative Christians and political conservatives. In this study, we investigate this opposition by examining support for Christian hegemony (i.e., the idea that Christianity should be the norm and Christians should be in power in the United States) and unawareness of Christian privilege (i.e., unearned advantages for Christians) as religiopolitical variables that help to explain the association between Christian and political conservatism and opposition to a host of SGM rights (same-sex marriage, same-sex adoption, nondiscrimination policies in jobs and housing for SGMs, and bills regarding transgender public bathroom use). Based on structural equation modeling analysis with heterosexual cisgender Christian (n = 688) and Areligious (n = 327) students, we demonstrate that support for Christian hegemony and unawareness of Christian privilege help to explain the association between Christian and political conservatism and opposition to SGM rights. These findings advance our understanding of a new type of religious-based variable focused on religious power and privilege to help understand conservative religious and political opposition to SGM rights. Limitations, implications, and directions for future research also are discussed.  相似文献

Research has shown that neighborhoods play a role in the etiology of violence. However, few adolescent relationship aggression (ARA) studies have objective measures of violent neighborhoods. Drawing on a nationally representative sample of youth, this study examines the association between ARA and local levels of violent crime (measured using geocoded Uniform Crime Report data from each of the youths’ residential neighborhoods). Study analyses are based on survey data from 723 youth (ages 10–18) in current or recent dating relationships (351 males and 372 females) in the Survey on Teen Relationships and Intimate Violence (STRiV), a national representative household panel survey exploring interpersonal violence and related aggression among adolescents. About 19% of the sample reported ARA victimization in their most recent dating relationship (ARA perpetration was 17%). Neighborhood violent crime in the study (males living in 86.9 and females 99.8) was slightly lower than the national average of 100. With a broad national sample, 40% non-Whites, hypotheses guided by theories of neighborhood influence were tested. The study did not find an association between neighborhood violent crime and ARA victimization and perpetration, controlling for key demographic factors. The results, for a broad range of high- and low-crime neighborhoods, suggest that neighborhood violence does not seem to affect individual rates of ARA. The results suggest the ARA victimization and perpetration are perhaps ubiquitous and found both in low and high violent crime neighborhoods, suggesting that addressing local violent crime rates alone does not seem to be a path to also reducing ARA.  相似文献

Penile plethysmography (PPG) is an objective measure of male sexual arousal in response to the presentation of a series of erotic and neutral stimuli. This measure is now widely recognized as the most reliable means of objectively measuring male sexual arousal to specific stimuli. Many clinicians and researchers consider PPG to be a vital contribution to the assessment and treatment of adult men with paraphilic interests and men who have committed sex crimes. PPG contributes to the clinical assessment of paraphilic interests, appraisal of risk of recidivism, and provides an objective measurement of changes in sexual arousal in response to treatment. There is strong support for the utility of PPG within clinical and legal contexts. This article addresses ways in which PPG has been utilized in the courts as part of expert clinical opinion. History of its use, details regarding admissibility in court, and case law are explored within the legal systems of Canada, the UK and the USA. Support for the inclusion of PPG as expert evidence is provided and judicial misunderstandings on the rationale for PPG use and its clinical utility in forensic assessments are discussed.  相似文献

The purpose of this content analysis was to illustrate trends related to the use of the term adverse childhood experiences (ACEs), or terms related to the 10 components of ACEs, within 140 peer-reviewed articles published in 22 journals affiliated with the American Counseling Association (ACA) and the American School Counselor Association (ASCA) between 1998 and 2018. Of the 9,120 articles published in the 22 ACA- and ASCA-affiliated journals in that time, only three articles (0.03%) explicitly mentioned the term adverse childhood experiences in the title, abstract, or keywords. Authors of 93 journal articles mentioned terms related to the original 10 categories of ACEs 104 times (1.0% of all published articles). The need for consistent language across research and practice is highlighted. Implications include ways that the counseling field may benefit from an increased clarity and focus around ACEs.  相似文献

English‐monolingual children develop a shape bias early in language acquisition, such that they more often generalize a novel label based on shape than other features. Spanish‐monolingual children, however, do not show this bias to the same extent (Hahn & Cantrell, 2012). Studying children who are simultaneously learning both Spanish and English presents a unique opportunity to further investigate how this word‐learning bias develops. Thus, we asked how Spanish–English bilingual children (Mage = 21.31 months) perform in a novel‐noun generalization (NNG) task, specifically examining how past language experience (i.e. language exposure and vocabulary size) and present language context (i.e. whether the NNG task was conducted in Spanish or English) influence the strength of the shape bias. Participants completed the NNG task either entirely in English (N = 16) or entirely in Spanish (N = 16), as well as language understanding tasks in both English and Spanish to ensure that they understood what the experimenter was asking them to do. Parents completed a language exposure survey and vocabulary checklists in Spanish and English. There was a significant interaction between condition and choice type: Bilingual children in the English condition showed a shape bias in the NNG task, but bilingual children in the Spanish condition showed no reliable biases. No measures of past language experience were related to NNG task performance. These results suggest that when learning new words, bilingual children are attuned to the regularities of the present language context, and prior language experiences may play a more secondary role.  相似文献

The Boston Naming Test has enjoyed increasing use in many research studies since its introduction. However, there is little normative data on the age group above 60 years of age. This study presents data from a sample of 58 well-defined healthy elderly males and females between the ages of 60 and 85. In comparison with published normative data, our sample has higher means, smaller standard deviations, and narrower ranges. These results suggest that aging alone does not significantly alter recognition-cued word-finding ability as defined by the Boston Naming Test. Also there is remarkably consistent performance throughout our age range.  相似文献

Spatial thinking is an important predictor of mathematics. However, existing data do not determine whether all spatial sub‐domains are equally important for mathematics outcomes nor whether mathematics–spatial associations vary through development. This study addresses these questions by exploring the developmental relations between mathematics and spatial skills in children aged 6–10 years (N = 155). We extend previous findings by assessing and comparing performance across Uttal et al.'s (2013), four spatial sub‐domains. Overall spatial skills explained 5%–14% of the variation across three mathematics performance measures (standardized mathematics skills, approximate number sense and number line estimation skills), beyond other known predictors of mathematics including vocabulary and gender. Spatial scaling (extrinsic‐static sub‐domain) was a significant predictor of all mathematics outcomes, across all ages, highlighting its importance for mathematics in middle childhood. Other spatial sub‐domains were differentially associated with mathematics in a task‐ and age‐dependent manner. Mental rotation (intrinsic‐dynamic skills) was a significant predictor of mathematics at 6 and 7 years only which suggests that at approximately 8 years of age there is a transition period regarding the spatial skills that are important for mathematics. Taken together, the results support the investigation of spatial training, particularly targeting spatial scaling, as a means of improving both spatial and mathematical thinking.  相似文献

This study tested Rusbult’s (1980, 1983) investment model of relationship commitment and stability using data from both partners of 3,627 married couples. As pre-dicted, spouses’ satisfaction, investments, and quality of alternatives were unique predictors of their commitment to the marital relationship. Additionally, commitment assessed at the initial testing predicted marital termination or stability 18 months later. Multiple-group path analyses showed that the investment model provided an adequate fit to the data and that the associations among variables were similar for husbands and wives. Limitations of the model as well as directions for future research are consid-ered. This research used the American Couples, 1975-1978, data set [made accessible in 1992, computer data]. These data were collected by Philip Blumstein and Pepper Schwartz and are available through the archive of the Henry A. Murray Research Center of Radcliffe College, Cambridge, Massachusetts (Producer and Distributor). This paper is based on work supported under a National Science Foundation Graduate Fellowship awarded to Emily A. Impett and a UCLA Academic Senate Research Grant to Letitia Anne Peplau. The authors are very grateful to Kevin Kim and Jodie Ullman for statistical consulting and Brian Doss for comments on an earlier draft.  相似文献
