Six samples of CCVC phoneme sequences were devised to represent linguistically specifiable distances from existing French words, distance being measured in terms of number of substitutions needed to make an existing French word. Fifty-four native speakers of French rated the sound sequences for their subjective proximity to French, using ungraded rating scales. Results showed a general correspondence between the linguistic and psychological measurements, although certain phoneme sequences did not follow the predicted order. These were examined to see if their displacement could be attributed to the number of different French words reached through substitutions.  相似文献

This is the report of the application of the principles of factorial design to an investigation of individual educational development. The specific type of factorial design formulated was a 2 × 3 × 3 × 3 arrangement, that is, the effect of sex, grade location, scholastic standing, and individual order, singly and in all possible combinations was studied in relation to educational development as measured by theIowa Tests of Educational Development. An application of the covariance method was introduced which resulted in increased precision of this type of experimental design by significantly reducing experimental error. The two concomitant measures used to increase the sensitiveness of the experiment were initial status of individual development and mental age. Without these statistical controls all main effects and two first-order interactions would have been accepted as significant. With their use only sex (doubtful), scholastic standing, and individual order demonstrated significant effects. The chief beauty of the analysis of variance and covariance as an integral part of a self-contained experiment is demonstrated in the complete single analysis of the data. The statistical utilization of the experimental results has also been developed for purposes of estimation and prediction. The mathematical statistician is being continuously required to develop and analyze experimental designs of increasing complexity since the introduction of the analysis of variance and covariance. The mathematical formulation and solution of the problem of this investigation is carried out. The methods illustrated and explained in this study, and modifications and extensions of them are capable of very wide application. The general principles can be used to various degrees and in a number of ways.For the research grant to finance this study, grateful acknowledgment is given to the Graduate School, the University of Minnesota.  相似文献

We report the case of a woman who pursued direct access genetic testing and then presented with concerns regarding a positive test result for Long-QT syndrome. Although the result ultimately proved to be a false positive, this case illustrates that costs associated with follow-up of direct access genetic testing results can be non-trivial for both the patient and for health care systems. Here we raise policy questions regarding the appropriate distribution of these costs. We also discuss the possibility that, when confronted by a direct access genetic test result that reports high risk for one or more actionable diseases, a family physician might feel compelled to act out of a desire to avoid liability, even when information regarding the accuracy and validity of the testing were not easily accessible. This case outlines lessons that can easily be translated into clinical practice, not only by genetic counselors, but also by family physicians, medical specialists and members of the public.  相似文献

Relative to the merits of authoritative parenting, potential adverse outcomes are well documented for authoritarian and permissive parenting. However, conclusions are typically drawn from single informants. The ability of youths’ emotion regulation skills to mediate outcomes in emerging adults has also not been fully explored. This study investigated whether emotion regulation mediated parenting style history and potential outcomes of mental health and delinquency. Parenting style history and emerging adults’ emotion regulation ability were reported by 110 youth and their caregivers; youth reported on mental health functioning and delinquency. Emerging adults’ emotion regulation ability partially mediated the association between authoritative parenting history and mental health functioning and authoritative parenting history was indirectly related to delinquency through emotion regulation; however, based on all reporters, emotion regulation ability was not associated with authoritarian or permissive parenting style history. Results support that the merits of authoritative parenting may lie in fostering better emotion regulation skills.  相似文献

There is increasing concern about the large civic engagement gap between Whites and Latina/o and African American youth. Some suggest this may be because traditional models and measures of civic engagement may not be as applicable for youth from historically marginalized groups. With an urban sample of middle and high school‐age youth (n = 903, 52% female), we used structural equation modeling to identify differences in civic pathways between youth from different racial/ethnic backgrounds. We found significant differences between groups including much stronger relationships between exposure to democratic practices and civic self‐efficacy and knowledge for African American and Latina/o youth than for White youth and a stronger relationship between civic knowledge and future civic engagement for Whites and Latina/os than for African Americans. These findings suggest that educators and researchers interested need to take into account the diversity of youths' racial experiences when examining youth civic development.  相似文献

Discussions about diversity rarely focus on overweight, obesity, and bias about body size (i.e., weight bias). These discussions allow students to develop self-awareness about how their biases can affect their clinical work, as well as the challenges and subsequent bias clients may face in their everyday lives and from clinical providers. One consequence of the rising prevalence of overweight and obesity in the United States is the increase in the level of weight bias and discrimination towards individuals who are overweight, which has been documented among mental and healthcare professionals. Thus, it is imperative that training programs integrate weight bias as a part of diversity training. The authors will review weight bias in mental and healthcare professions, and describe several trainings focused on self-awareness about weight bias. The purpose of this study was to pilot and evaluate a training program for marriage and family therapy (MFT) students about developing self-awareness around weight bias and working with clients who are overweight. Following the program, focus groups were conducted to explore participants’ experiences, learning, and feedback on the content and delivery method. Focus Group methodology was used to guide the analysis process. Four themes emerged: training program feedback, challenges for the MFT field, self-of-therapist, and etiology of weight loss/gain. Implications for MFT training programs are discussed.  相似文献
