In a recent critique Boles and Barth (2011) argue that their prior study investigating asymmetry/performance relationships (Boles, Barth, & Merrill, 2008) uncovered the “true” association (i.e., negative correlation) between lateralization of visual lexical processes and word recognition performance. They contend that our study reporting positive correlations of lexical asymmetry and reading performance (Chiarello et al., 2009) was flawed and hence inconclusive. In this response we address the two major objections raised by Boles and Barth (2011) regarding our selection of tasks and asymmetry measures. We conclude that the Boles and Barth principle of task purity is not relevant to the stated aims of our investigation, and that our linear regression method of measuring asymmetry is valid given the high level of accuracy for the tasks we reported. Because the aims of each investigation differed, we argue that it is unwise to attempt to fit each study into the framework favored by Boles and Barth (2011). 相似文献
This article features information about a lawsuit brought by a former student against Eastern Michigan University and its counseling program. In addition to describing the major elements of the lawsuit, the authors reflect on lessons learned and offer recommendations for other counseling programs. 相似文献
The shifts in relative phase that are observed when rhythmically coordinated limbs are submitted to asymmetric mass perturbations have typically been attributed to the induced eigenfrequency difference (delta omega) between limbs. Modeling the moving limbs as forced linear oscillators, however, reveals that asymmetric mass perturbations may induce a difference not only in eigenfrequency (i.e., delta omega not equal 0) but also in the covarying low-frequency control gains (i.e., delta k not equal 0). Because the inverse of the low-frequency control gain (k) reflects the level of muscular torque (input) required for a particular displacement from equilibrium (output), asymmetric mass perturbations may result in an imbalance in the muscular torques required for task performance (related to delta k not equal 0). Thus, it is possible that the effects attributed to delta omega were in fact mediated by delta k. In 2 experiments, the authors manipulated delta k and delta omega separately by applying mass perturbations to the lower legs of 9 participants. The relative phasing between the legs was not affected by delta k, but manipulation of delta omega (while delta k remained approximately 0) induced systematic relative phase shifts that were more pronounced for antiphase than for in-phase coordination. That indication that the coordination dynamics is indeed influenced by an imbalance in eigenfrequency is discussed vis-a-vis the question of how such a merely peripheral property may affect the underlying coordination process. 相似文献
Although the detrimental influence of parenting stress on child problem behavior is well established, it remains unknown how these constructs affect each other over time. In accordance with a transactional model, this study investigates how the development of internalizing and externalizing problems is related to the development of parenting stress in children aged 4–9. Mothers of 1582 children participated in three one-year interval data waves. Internalizing and externalizing problems as well as parenting stress were assessed by maternal self-report. Interrelated development of parenting with internalizing and externalizing problems was examined using Latent Growth Modeling. Directionality of effects was further investigated by using cross-lagged models. Parenting stress and externalizing problems showed a decrease over time, whereas internalizing problems remained stable. Initial levels of parenting stress were related to initial levels of both internalizing and externalizing problems. Decreases in parenting stress were related to larger decreases in externalizing problems and to the (stable) course of internalizing problems. Some evidence for reciprocity was found such that externalizing problems were associated with parenting stress and vice versa over time, specifically for boys. Our findings support the transactional model in explaining psychopathology. 相似文献
Recent studies find that Black women experience rates of eating pathology and body dissatisfaction comparable to those of White women. Abundant research suggests that objectification theory could help explain the development and maintenance of eating disorder (ED) symptoms among diverse women. However, research on the applicability of objectification theory to ED symptoms in Black women is equivocal. Specifically, some have suggested that body surveillance might operate differently for Black women. Thus, the current study examined ethnic-racial identity (ERI) commitment and body appreciation as moderators of the mediated associations among body surveillance, body shame, and ED symptoms. Black women (n?=?175) in the United States completed measures of body image, ERI commitment, and ED symptoms. Consistent with objectification theory, body shame mediated the association between body surveillance and ED symptoms. Contrary to our hypothesis, ERI commitment did not moderate the link between body surveillance and body shame. However, body appreciation was a significant moderator, such that the strength of the relation between body surveillance and ED symptoms via body shame was weakened at high levels of body appreciation. Future work should consider interventions that foster body appreciation in Black women.
The purpose of the research was to identify empirically and measurably those dimensions considered important by laity in evaluating their priest. The 83-item questionnaire was developed from existing instruments and from an interview survey carried out on laity from a national selection of Episcopal parishes. 221 parishes responded with complete data. A factor analysis was performed on the data yielding eight useable factors: (a) Pastoral sensitivity, (b) Administrative Skills, (c) Scholarship, (d) Personal Integrity, (e) Innovation, (f) Personal Spirituality, (g) Meaningfulness of Services, and (h) Laity Involvement. The results of the research were seen as a beginning insight into what the laity perceived as important aspects of their parish priest's role, and an instrument to measure these dimensions for further research was produced. 相似文献
CONTEXT: Alcohol use is frequently identified as a contributor to risky sexual behaviors; however, research results are mixed. Given the conflicting evidence, researchers have focused on other factors, such as expectations about alcohol's effects that might help explain the relationship of alcohol use and risky sexual behaviors. METHODS: Cross-sectional data from 312 sexually experienced males aged 18-30 in a shantytown in Lima, Peru, were used in logistic regression models to identify associations of heavy episodic drinking and sex-related expectations about alcohol with sexual risk behaviors. RESULTS: Heavy episodic drinking was associated with having had two or more sexual partners and having had sex with a casual partner in the past year (odds ratios, 2.8 and 2.5, respectively). After controlling for alcohol consumption, sex-related expectations about alcohol were associated with these high-risk sexual behaviors, as well as with not using a condom at last sex (1.2) and not using a condom at last sex with a casual partner (1.3). CONCLUSION: Beliefs about the effect of alcohol on sexual performance could help explain links between alcohol consumption and risky sexual behavior not completely accounted for by the pharmacological effects of alcohol. 相似文献
