How can children's natural perceptuo-motor skills be harnessed for teaching and learning mathematical structure? We address this question in the case of the integers. Existing research suggests that adult mental representations of integers recruit perceptuo-motor functionalities involving symmetry. Building on these findings, we designed a hands-on curriculum that emphasizes symmetry to teach integer concepts to fourth graders. Compared to two control conditions, children who went through the experimental curriculum showed evidence of incorporating symmetry into their mental representations of integers and performed higher on problems beyond the scope of instruction, including negative fractions and algebra-readiness problems. Gains did not come at the expense of basic integer computation skill. This study has direct practical implications, as current integers curricula generally omit symmetry. The research demonstrates an approach to designing instruction that involves identifying perceptuo-motor functionalities underlying numerical cognition and creating learning activities to recruit them.  相似文献

This article will present an approach for accommodating the benefits of mindfulness into therapy with Christians struggling with worry. Given the psychological benefits of mindfulness and its connection to spirituality, it is not surprising that both therapists and Christian clients are attempting to incorporate it into counselling. Centering prayer, which is a form of Christian Devotion Meditation, provides an accommodative approach to managing worry for Christian clients. The results of this study indicate that surrender, a key component of centering prayer, provides an empirical link for incorporating the benefits of mindfulness for Christians.  相似文献

We tested a model of antecedents and outcomes of commitment to the environment, defined as psychological attachment and long‐term orientation to the natural world, hypothesizing that satisfaction with, investments in, and subjective norms about the environment would predict commitment, which, in turn, would predict willingness to sacrifice for the environment. In two studies, the model was supported in undergraduate and community samples, and for general commitment to the environment as well as commitment to specific proenvironmental behaviors. Individuals who are satisfied with and invested in the natural world, and who believe that those close to them value it as well, are likely to be committed to the environment and be willing to forego selfish interests to behave proenvironmentally.  相似文献

This study examined the associations among chronic stress, activation in the prefrontal cortex (PFC), executive function, and coping with stress in at-risk and a comparison sample of adolescents. Adolescents (N = 16; age 12–15) of mothers with (n = 8) and without (n = 8) a history of depression completed questionnaires, neurocognitive testing, and functional neuroimaging in response to a working memory task (N-back). Children of depressed mothers demonstrated less activation in the anterior PFC (APFC) and both greater and less activation than controls in distinct areas within the dorsal anterior cingulate cortex (dACC) in response to the N-back task. Across both groups, activation of the dorsolateral PFC (DLPFC; Brodmann area [BA9]) and APFC (BA10) was positively correlated with greater exposure to stress and negatively correlated with secondary control coping. Similarly, activation of the dACC (BA32) was negatively correlated with secondary control coping. Regression analyses revealed that DLPFC, dACC, and APFC activation were significant predictors of adolescents’ reports of their use of secondary control coping and accounted for the effects of stress exposure on adolescents’ coping. This study provides evidence that chronic stress may impact coping through its effects on the brain regions responsible for executive functions foundational to adaptive coping skills.  相似文献

We explore the nature and evolution of the role of candidates' spouses in U.S. presidential election campaigns through a lens of social psychological theorizing that sees leadership as emerging from activities of identity construction of leaders and followers. Our discursive analysis examines how aspiring First Lady speeches at party national conventions construct both their husbands and the particular national identity construction most presently politically relevant in a way that strategically aligns the two. Building on previous social identity work on leadership, we show how it is not only the leader or their followers who are active participants in leadership construction but that there may also be a role for “third parties” who link prospective leaders with followers. We propose that, as “entrepreneurs” of identity, leaders may use others as “identity mediators” to co‐construct and mediate both the leader's identity and the identity of those they seek to lead.  相似文献

Research on sense of community (SOC) has traditionally been approached from a resource perspective. Recently, however, research on the experience of SOC has evolved to include a related but distinct construct of sense of community responsibility (SOC‐R), or feelings of accountability for the well‐being of a community. This study applied item response theory to examine the psychometric properties of a SOC‐R scale used in an evaluation of community‐based substance abuse prevention coalitions. Data were collected in 2017 from coalition members (analytic sample = 309) in the northeastern United States. Findings indicate that the scale was reliable, unidimensional, and functioned well, particularly at low and moderate levels of the construct. The addition of two items intended to capture higher levels of the construct improved the scale's functioning at higher levels of SOC‐R. The adapted SOC‐R scale was also shown to have moderately strong relationships with conceptually relevant variables, including SOC, coalition participation, number of roles performed in the coalition, and engagement in community action activities. These findings provide empirical evidence to support the reliability and validity of the SOC‐R scale, and have critical implications for our conceptualization of the SOC construct, its measurement, and for the evaluation of community‐based prevention interventions.  相似文献

The Internal Consent Scale (ICS) was created to measure feelings associated with a person’s willingness to engage in partnered sexual activity. Although previous studies using the ICS have assessed gender differences, evidence has not been provided to suggest that the ICS functions similarly for women and men. Using data from an online cross-sectional survey of adults (N = 874; 53.1% women), we subjected the 25-item ICS to tests of measurement invariance across gender. We found that only partial measurement invariance was tenable, which indicated that direct comparisons across gender should be interpreted with caution when using the ICS. Therefore, we created a gender-invariant short form. In support of construct validity, we found that this 15-item ICS–Short Form demonstrated similar associations with measures of sexual consent communication as the full 25-item ICS. If researchers aim to compare women and men on internal sexual consent, we recommend using the 15-item ICS–Short Form. Cognitive interviews should be conducted to further understand how women and men might differentially interpret ICS items.

There are few psychometrically sound measures of coping in adults. Widely used measures of coping have highly unstable sub-scale analyses, were developed on homogenous samples, and are outdated. The scarcity of empirically derived instruments is concerning given that coping skills are linked to a variety of positive and negative physical and mental health outcomes (e.g., substance use, depression). Thus, the aim of the current study was to develop a psychometrically sound measure of coping in adults: the Adult Coping Inventory (ACI). The study consisted of three phases: The aim of Phase 1 was to generate an initial item pool. After eliminating redundant items, 124 items remained. The purpose of Phase 2 was to eliminate items based on item frequency and factor loadings. A diverse sample of 526 adults participated in the study. Following item generation and elimination, an exploratory factor analysis produced a 57-item, five-factor model of coping which included the following subscales: Problem Solving, Mindfulness, Maladaptive Coping, Social Support, and Avoidance. Overall, reliability of the ACI was excellent and the internal consistency of the factors ranged from adequate to excellent. Evidence of convergent, concurrent, and incremental validity of the questionnaire was also established. Results provide initial support for the psychometric properties of the ACI.

OBJECTIVE: Evidence indicates that depression is linked to the development and worsening of diabetes, but the mechanisms underlying this link are not well understood. The authors examined the hypothesis that diabetes-related symptoms mediate the effect of both behavioral adherence and body mass index (BMI) on depression. In addition, they examined whether a prior finding that self-efficacy mediates the effect of behavioral adherence and BMI on depression would replicate with a larger sample size (W. P. Sacco, K. J. Wells, C. A. Vaughan, A. Friedman, S. Perez, & R. Morales, 2005). Also, the relative contributions of diabetes-related symptoms and self-efficacy to depression were evaluated. DESIGN AND PARTICIPANTS: Cross-sectional design involving adults diagnosed with Type 2 diabetes (N = 99). MAIN OUTCOME MEASURES: The primary outcome measure was depression (Patient Health Questionnaire: Nine Symptom Depression Checklist). Predictors of depression were diet and exercise adherence (Summary of Diabetes Self-Care Activities Questionnaire), diet and exercise self-efficacy (Multidimensional Diabetes Questionnaire), diabetes symptoms (Diabetes Symptom Checklist), and BMI (based on height and weight data from medical records). RESULTS: Path and mediation analyses indicated that adherence and BMI each contributed to depression indirectly, via their effects on self-efficacy and diabetes-related medical symptoms. CONCLUSION: Results provide evidence consistent with two independent pathways by which BMI and adherence could increase depression in people with Type 2 diabetes. The first pathway indicates that the effects of higher BMI and poor adherence on depression are mediated by lower self-efficacy perceptions. The second pathway indicates that the effect of higher BMI on depression is mediated by increased diabetes symptoms.  相似文献
