The purpose of this study was to specify the relationship between positive and harsh parenting and maternal scaffolding behavior. A 2nd aim was to disentangle the effects of maternal education and parenting quality, and a 3rd aim was to test whether parenting quality mediated the association between maternal education and scaffolding practices. We examined associations between positive and harsh parenting practices and contingent and noncontingent tutoring strategies. Ninety-six mother-child dyads (49 boys, 47 girls) from working- and middle-class English families participated. Mothers reported on parenting quality at Time 1 when children were 5 years old and again approximately 5 years later at Time 2. Mother-child pairs were observed working together on a block design task at Time 2, and interactions were coded for contingent (contingent shifting) and noncontingent (fixed failure feedback) dimensions of maternal scaffolding behavior. Positive and harsh parenting accounted for variance in contingent behavior over and above maternal education, whereas only harsh parenting accounted for unique variance in noncontingent scaffolding practices. Our findings provide new evidence for a more differentiated model of the relation between general parenting quality and specific scaffolding behaviors.  相似文献

Exergames are videogames that require gross motor activity, thereby combining gaming with physical activity. This study examined the role of competitive versus cooperative exergame play on short-term changes in executive function skills, following a 10-week exergame training intervention. Fifty-four low-income overweight and obese African American adolescents were randomly assigned to a competitive exergame condition, a cooperative exergame condition, or a no-play control group. Youths in the competitive exergame condition improved in executive function skills more than did those in the cooperative exergame condition and the no-play control group. Weight loss during the intervention was also significantly positively correlated with improved executive function skills. The findings link competitive exergame play to beneficial cognitive outcomes for at-risk ethnic minority adolescents.  相似文献

We examined a procedure consisting of a preference assessment, prompting, contrived conditioned establishing operations, and consequences for correct and incorrect responses for teaching children with autism to mand “which?” We used a modified multiple baseline design across 3 participants. All the children learned to mand “which?” Generalization occurred to the natural environment, to a novel activity, and to a novel container; the results were maintained over time.Key words: mand for information, verbal behavior, verbal operant, whichContrived motivating operations have been used to teach mands for information to children with autism, including the mands “what?” (e.g., Williams, Donley, & Keller, 2000), “where?” (e.g., Betz, Higbee, & Pollard, 2010; Lechago, Carr, Grow, Love, & Almason, 2010), and “who?” (e.g., Endicott & Higbee, 2007; Sundberg, Loeb, Hale, & Eigenheer, 2002). More recently, researchers have examined the effects of contriving establishing operations (CEOs) in four different ways to teach children with autism to acquire the mands “what?” (Marion, Martin, Yu, & Buhler, 2011; Roy-Wsiaki, Marion, Martin, & Yu, 2010) and “where?” (Marion, Martin, Yu, Buhler, & Kerr, in press). Like the mands “what?” and “where?,” the mand “which?” is a mand for information that gives the speaker the ability to gather specific information regarding an item (e.g., “Which book is mine?”). Given the dearth of research that has examined interventions to teach mands for information using “which?,” the purpose of the present study was to extend the work of Marion et al. (2011, in press) by contriving one of four CEOs for teaching the mand “which?” to children with autism, and to assess for generalization to the other CEOs, the natural environment, and over time.  相似文献

The primary objective of this investigation was to examine the joint influences of intention strength, executive control resources (ECRs) and implementation intentions on physical activity performance in differentially supportive environmental conditions. In two studies, participants were randomly assigned to implementation intentions or control conditions. Individual differences in ECRs, intention strength and physical activity behavior were measured at baseline in the laboratory; follow-up physical activity was measured via an online questionnaire 7 days after the baseline laboratory session. Study 1 was conducted under activity-supportive environmental conditions (i.e., warm weather, little precipitation), whereas Study 2 was conducted under non-supportive environmental conditions (i.e., cold weather, moderate precipitation). In Study 1, a two-way interaction between ECR and intention strength was observed, such that those with relatively stronger ECR demonstrated stronger intention–behavior relationships than those with relatively weaker ECR; this effect was invariant across experimental conditions. In Study 2, a significant 3-way interaction was observed, such that those with lower ECRs showed greater intention–behavior correspondence in the experimental group compared to the control. Together these findings suggest that the beneficial effects of implementation intentions on intention–behavior correspondence for physical activity may be more potent under challenging environmental conditions, and that they may be of special benefit for those with initially low ECRs.  相似文献

Teenage drivers have been shown to have some of the highest crash risks. Crash data provide some insights on factors related to crash likelihood, but rarely capture all issues that can arise from driver distraction. The goal of this study was to assess teenage drivers’ opinions and perceptions of driver distraction. A survey of 1893 Iowa teenagers was conducted to determine and compare the frequency of engagement in distracting activities while driving to their opinions of what they actually consider to be distractions. A cluster analysis was conducted based on their indicated engagement in distracting activities with three groups emerging and classified as INFREQUENT, MODERATE, and FREQUENT engagers. Across all cluster groups, the majority (over 80%) indicated that they considered text messaging to be a distracting task. However, those clustered as FREQUENT engagers still reported a high level of texting while driving even though they considered this task to be distracting. A binary logistic regression model (adjusted for miles driven and license type) showed that FREQUENT and MODERATE engagers were more likely to be involved in a crash when compared to INFREQUENT engagers. The study demonstrates that not all teenagers place themselves at risk. There are subgroups of teenage drivers that often engage in activities they know are distracting, potentially putting themselves in danger. However, this is not the case for all teenage drivers and it is important to target interventions appropriately as well as foster a culture of safety both in schools and at home.  相似文献

Research on rail passenger crowding often tacitly subscribes to a measurement of crowding based on density (i.e. physical conditions involving space limitations) and rarely considers the possible role psychological factors may play in measuring this construct. This paper describes the development of an instrument that captures the dimensionality of rail passenger crowding and its relationship to the experience of stress and feelings of exhaustion. The proposed instrument is a 20-item self-rating questionnaire consisting of three sub-scales designed to assess subjective crowding experiences among rail users (n = 525). Findings from the factor analyses generally support the hypothesised three-factor structure of the measurement model (evaluation of the psychosocial aspects of the crowded situation, evaluation of the ambient environment of the crowded situation, and affective reactions to the crowded situation). All sub-scales demonstrate excellent internal consistency and construct validity as well as good convergent and discriminant validity values. The instrument was further tested using structural equation modelling to examine the impact of crowding on commuters’ stress and feelings of exhaustion. With the addition of the “passenger density” variable as an indicator of objective measurement of crowding operating in tandem with the crowding sub-scales, the results reveal that: (1) commuters’ evaluations of the psychosocial aspects of the crowded situation and of its ambient environment, alongside their rating of passenger density, significantly predict affective reactions to the crowded situation; (2) these affective reactions, in turn, significantly predict stress and feelings of exhaustion; and (3) evaluations of the psychosocial aspects of the crowded situation and of its ambient environment as well as passenger density do not directly predict stress and feelings of exhaustion. The link between rail passenger crowding and the negative outcomes therefore does not appear as a simple, direct relationship, but is mediated by affective feelings of crowdedness. Overall, these results provide satisfactory psychometric properties for the proposed instrument and support its use as an assessment tool for measuring crowding experience in the rail setting.  相似文献

ObjectivesLittle is known about elite athletes who are mothers within the context of sociocultural expectations concerning motherhood and sport. The aim of this study was to extend such understanding by examining how the media manages and constructs one elite athlete's (Paula Radcliffe) identities within the context of motherhood and sport.DesignA qualitative approach grounded in cultural sport psychology was used to explore motherhood and athletic identity as socio-cultural creations shaped by cultural narratives (i.e., media). The psychological and behavioural implications were of interest.MethodA textual analysis (see McKee, 2003) of two issues of Runner's World magazine (March 2008, October, 2010) surrounding elite British marathon runner Paula Radcliffe's pregnancies was conducted. Visual data analysis of 37 images (see Griffin, 2010) further contextualized textual meaning(s).ResultsRadcliffe's identities were constructed within a higher order narrative: pregnancy and motherhood as redemption. This narrative had fluid meanings depending on how it framed two contrasting identities: 1. athlete and mother as one and 2. primarily a mother; athlete as secondary. An athlete and mother as one identity reinforced an elite athlete identity and high performance narrative. A primarily mother, athlete as secondary identity was linked to athletic accomplishments being downplayed and/or sacrificed in favour of motherhood.ConclusionsThis study opens a new window of cultural understanding and possibility for research and application concerning motherhood and athletic identities. These findings add to the cultural sport psychology and qualitative literature exploring elite mothering athletes.  相似文献

A peer instruction model was used whereby 78 residence dons (36 males, 42 females) provided instruction regarding academic integrity for 324 students (125 males, 196 females) under their supervision. Quantitative and qualitative analyses were conducted to assess survey responses from both the dons and students regarding presentation content, quality, and learning. Overall, dons consistently identified information-based slides about academic integrity as the most important material for the presentations, indicating that fundamental information was needed. Although student ratings of the usefulness of the presentations were middling, students did indicate knowledge gains. Both interest and personal value for academic integrity were highly predictive of positive evaluations of the presentations. Dons and students provided suggestions for improvement and identified more global concerns.  相似文献

We often remember in groups, yet research on collaborative recall finds "collaborative inhibition": Recalling with others has costs compared to recalling alone. In related paradigms, remembering with others introduces errors into recall. We compared costs and benefits of two collaboration procedures--turn taking and consensus. First, 135 individuals learned a word list and recalled it alone (Recall 1). Then, 45 participants in three-member groups took turns to recall, 45 participants in three-member groups reached a consensus, and 45 participants recalled alone but were analysed as three-member nominal groups (Recall 2). Finally, all participants recalled alone (Recall 3). Both turn-taking and consensus groups demonstrated the usual pattern of costs during collaboration and benefits after collaboration in terms of recall completeness. However, consensus groups, and not turn-taking groups, demonstrated clear benefits in terms of recall accuracy, both during and after collaboration. Consensus groups engaged in beneficial group source-monitoring processes. Our findings challenge assumptions about the negative consequences of social remembering.  相似文献

Cultural intelligence (CQ) – the capability to function effectively in intercultural settings – has gained increasing attention from researchers and practitioners due to its contemporary relevance to globalization, international management, and workforce diversification. Research‐to‐date demonstrates that CQ predicts a variety of important outcomes in intercultural contexts, such as cultural adaptation, expatriate performance, global leadership, intercultural negotiation, and multicultural team processes. Moving beyond past research that tends to focus on the four primary factors of CQ – metacognitive CQ, cognitive CQ, motivational CQ, and behavioral CQ, we introduce an expanded conceptualization of CQ that delineates sub‐dimensions for each of the four factors. We briefly review psychometric evidence supporting the proposed second order 11‐factor structure and convergent/discriminant validity of the sub‐dimensions. We propose that the next wave of CQ research should be guided by a deeper understanding of each of four factors of CQ.  相似文献
