Investigating cognitive transfer within the framework of music practice: genetic pleiotropy rather than causality 下载免费PDF全文
Miriam A. Mosing Guy Madison Nancy L. Pedersen Fredrik Ullén 《Developmental science》2016,19(3):504-512
The idea of far transfer effects in the cognitive sciences has received much attention in recent years. One domain where far transfer effects have frequently been reported is music education, with the prevailing idea that music practice entails an increase in cognitive ability (IQ). While cross‐sectional studies consistently find significant associations between music practice and IQ, randomized controlled trials, however, report mixed results. An alternative to the hypothesis of cognitive transfer effects is that some underlying factors, such as shared genes, influence practice behaviour and IQ causing associations on the phenotypic level. Here we explored the hypothesis of far transfer within the framework of music practice. A co‐twin control design combined with classical twin‐modelling based on a sample of more than 10,500 twins was used to explore causal associations between music practice and IQ as well as underlying genetic and environmental influences. As expected, phenotypic associations were moderate (r = 0.11 and r = 0.10 for males and females, respectively). However, the relationship disappeared when controlling for genetic and shared environmental influences using the co‐twin control method, indicating that a highly practiced twin did not have higher IQ than the untrained co‐twin. In line with that finding, the relationship between practice and IQ was mostly due to shared genetic influences. Findings strongly suggest that associations between music practice and IQ in the general population are non‐causal in nature. The implications of the present findings for research on plasticity, modularity, and transfer are discussed. 相似文献

Attachment theory assumes that trust in caregivers’ support and exploration are closely related. Little research tried to investigate this link, nor focuses on mechanisms that might explain this association. The present studies examined whether trust is related to exploration through a serial indirect effect of openness to negative affect and self‐regulation. In Study 1, 212 children, aged 8–13, completed questionnaires assessing trust, openness to negative affect, self‐regulation and exploration. The results showed that trust predicted exploration, but only to the extent to which openness to negative affect and self‐regulation were involved too. Study 2 refined these findings (n = 59, aged 9–12) using a behavioral measure of openness to negative affect and exploration, and with mother‐reported self‐regulation. Replicating this serial indirect effect of openness to negative affect and self‐regulation with multiple informants and methods, the present studies advance our understanding of how trust might foster exploration in preadolescence. 相似文献

Contract cheating, or plagiarism via paid ghostwriting, is a significant academic ethical issue, especially as reliable methods for its prevention and detection in students’ assignments remain elusive. Contract cheating in academic assessment has been the subject of much recent debate and concern. Although some scandals have attracted substantial media attention, little is known about the likely prevalence of contract cheating by students for their university assignments. Although rates of contract cheating tend to be low, criminological theories suggest that people who employ ghostwriters for their assignments are likely to re-offend, and little is known about re-offence rates in this form of academic misconduct. We combined previously-collected datasets (N = 1378) and conducted additional, and previously-unreported, analyses on self-report measures of contract cheating prevalence. We found that few students (3.5%), on aggregate, ever engaged in contract cheating but this varied substantially among samples (from 0.3% to 7.9%). Of those who ever engaged in contract cheating, 62.5% did so more than once. The data also suggested that engagement in contract cheating is influenced by opportunity. These figures may help policy makers, and researchers who are creating contract cheating detection methods, to estimate base rates of contract cheating and the likelihood of re-offence. 相似文献

Despite the large literature concerning the impact of hope and expectancy on various outcomes (e.g., nonvolitional), less is known about the constructs of hope and expectancy themselves. In a recent study, Montgomery et al. (2003) demonstrated that hopes and expectancies are separate but related constructs; however, because both hopes and expectancies were measured within the same context, it is possible that these findings were simply a methodological artifact. Furthermore, it is unknown whether these data would generalize to other populations. Taking into account the importance of this distinction for both the expectancy and hope literatures, the present study sought to: (1) Determine if the distinction between hope and expectancy is a general and reliable phenomenon by using a culturally different sample (i.e., Romanian sample); and (2) Examine the robustness of this distinction by controlling for the context effect. One hundred-twenty five volunteers completed items in regard to 10 nonvolitional outcome scenarios in one of five measurement contexts. The results revealed that hope and expectancy were distinct constructs (p<0.0001), and that this distinction is both general and robust across contexts. Implications for theory and research are discussed. 相似文献

Studies of the therapeutic alliance typically use a one-with-many (OWM) design in which each therapist (the one) treats multiple clients (the many). This study used Kenny, Kashy, and Cook's (2006) OWM method to examine the composition of the therapeutic alliance and to analyze the association between alliance and outcome in a sample of 398 adolescents treated for substance abuse by 14 therapists. Both the client and therapist alliance ratings yielded large relationship variances, with limited consensus among clients treated by the same therapist about the quality of the alliance. If a client reported an especially strong alliance with his or her therapist, the therapist was likely to also report an especially strong alliance with that client (dyadic reciprocity). The association between the components of the alliance and treatment outcome was complicated, with different levels of measurement and different components of the alliance (perceiver, partner, or relationship) derived from different informants (therapist or client) relating to different outcomes. 相似文献

Antisocial and psychopathic traits are essential to evaluate when assessing risk for violence using the HCR-20. The role of the PCL-R on the HCR-20 was investigated using a series of meta-analytic tests. Across 34 samples in which both tools were rated, AUCs for violence were similar (~.69), and exclusion of the psychopathy item (H7) did not reduce the HCR-20's accuracy. Quantitative synthesis of results from multivariate analyses conducted in 7 raw datasets that used both tools demonstrated that the average probability of observing violence for every point increase on the HCR-20 (without H7), while controlling for the PCL-R, was 23%, whereas for the PCL-R it was -1%. The HCR-20 (without H7) added incremental validity to the PCL-R, whereas the converse was not true, and only the HCR-20 (without H7) possessed unique predictive validity. Results suggest the HCR-20's predictive validity was not negatively impacted by excluding the PCL-R. Areas for future study are discussed, including research on various ways to assess and incorporate into risk assessment personality traits related to violence. 相似文献

This study explored the relationship between parents' use of conditional regard (PCR, Assor, Roth, & Deci, 2004; Roth, 2008) to promote suppression of sad feelings and the following emotional skills in young children: (1) recognition of sadness in facial expressions, (2) awareness of sad feelings in oneself, and (3) empathic response to others' sad feelings. The study distinguished between two PCR components: conditional negative regard (similar to love withdrawal) and conditional positive regard. Emotion‐focused interviews were conducted with 102 children aged 5–6 years, and their parents completed questionnaires assessing parents' use of conditional regard. As expected, both PCR components correlated negatively with the emotional skills. Regression analyses showed that the seemingly benign practice of conditional positive regard had unique negative associations with the three emotional skills also when effects of negative PCR were controlled.
