Individual differences in musical training and executive functions: A latent variable approach

Learning and performing music draw on a host of cognitive abilities, and previous research has postulated that musicians might have advantages in related cognitive processes. One such aspect of cognition that may be related to musical training is executive functions (EFs), a set of top-down processes that regulate behavior and cognition according to task demands. Previous studies investigating the link between musical training and EFs have yielded mixed results and are difficult to compare. In part, this is because most studies have looked at only one specific cognitive process, and even studies looking at the same process have used different experimental tasks. Furthermore, most correlational studies have used different “musician” and “non-musician” categorizations for their comparisons, so generalizing the findings is difficult. The present study provides a more comprehensive assessment of how individual differences in musical training relate to latent measures of three separable aspects of EFs. We administered a well-validated EF battery containing multiple tasks tapping the EF components of inhibition, shifting, and working memory updating (Friedman et al. in Journal of Experimental Psychology: General, 137, 201–225, 2008), as well as a comprehensive, continuous measure of musical training and sophistication (Müllensiefen et al., in PLoS ONE, 9, e89642, 2014). Musical training correlated with some individual EF tasks involving inhibition and working memory updating, but not with individual tasks involving shifting. However, musical training only predicted the latent variable of working memory updating, but not the latent variables of inhibition or shifting after controlling for IQ, socioeconomic status, and handedness. Although these data are correlational, they nonetheless suggest that musical experience places particularly strong demands specifically on working memory updating processes.     

Thin Is In? Think Again: The Rising Importance of Muscularity in the Thin Ideal Female Body

Research has documented an increased emphasis on fitness in media targeting women. However, it is unclear whether this emphasis has resulted in increased muscularity in the perceived ideal female body shape. We sought to evaluate whether the ideal female figure has incorporated increased muscularity into the existing ideal body type that already emphasizes thinness. In Study 1, 78 female undergraduates evaluated images of U.S. beauty pageant winners over the past 15 years on dimensions of thinness, muscularity, and attractiveness. Results indicated that muscularity and thinness ratings of pageant winners significantly increased over time. In Study 2, 64 female undergraduates evaluated two different versions of the same image of a model: a Thin Muscular image and a Thin Only image in which the appearance of muscularity was removed through digital editing. When images were presented in pairs, results indicated that participants found the Thin Muscular image more attractive than the Thin Only image. These results suggest that the current perceived ideal female figure includes both extreme thinness and muscularity and that women prefer this muscular thin figure to a solely thin figure. These findings have implications for clinical treatments related to body image, compulsive exercise, and media literacy.     

DARWIN AND CHRISTIANITY: TRUTH AND MYTH

In recent years many historical myths about the relations between science and religion have been corrected but not always with sensitivity to different types and functions of “myth.” Correcting caricatures of Darwin's religious views and of the religious reaction to his theory have featured prominently in this myth‐busting. With the appearance in 2017 of A. N. Wilson's depiction of Darwin himself as a “mythmaker,” it is appropriate to reconsider where the myths lie in discourse concerning Darwin and Christianity. Problems with Wilson's account are identified and his provocative demeaning of Darwin is contrasted with an image gleaned from Darwin's friend and colleague George Romanes. The article concludes with a brief reference to the problem of suffering and to the work of Christopher Southgate.     

Perspective taking in conflict settings: Can perspective taking smooth tensions between Trump and Clinton supporters in the aftermath of 2016 U.S. presidential election?

Can perspective taking improve intergroup attitudes in conflict contexts? How does a context of conflict shape people's responses to perspective-taking tasks and their ultimate effectiveness? The present study addressed these questions by examining the effect of perspective taking (compared with a perspective giving and a control condition) on intergroup attitudes between Trump and Clinton supporters (N = 537) one month after the 2016 presidential election. Perspective taking had positive effects on some intergroup attitudes: It increased warmth toward the outgroup (thermometer ratings), outgroup tolerance, perceived similarities between groups, and marginally increased positive outgroup evaluation. This study also sheds light on the mechanisms that might reduce the effectiveness of perspective taking in conflict settings by assessing the content and the effects of the induced perspectives in response to perspective-taking task. About half of the induced perspective-taking narratives involved negative views of the other, which were associated with worse intergroup outcomes. In addition, higher perceived intensity of the conflict between Trump and Clinton supporters and more negative emotions about the election outcome predicted more induced negative perspectives as a response to the perspective-taking task. In turn, negative perspectives were associated with more negative intergroup attitudes. To sum up, while perspective taking had an overall positive impact on intergroup attitudes in this conflict setting, its impact seems to be contingent upon the content of induced perspective-taking narratives.

Raising One Eyebrow and Re‐envisioning Justice,Gender, and the Family

As part of a celebration of Susan Okin's Justice, Gender, and the Family (JGF), this article notes how some impacts of the book were so accepted that their original source (JGF) has been forgotten. It goes on to make three critical arguments about 1) Okin's pared‐down account of gender injustice, 2) her choice to embrace the Rawlsian distributive view of justice, and 3) her treatment of the family as the linchpin of gender injustice.     

Psychometric Evaluation of the Spiritual Transcendence Scale in a Chinese Sample: Is There Factorial Invariance Across Gender,Occupation, and Religion?

This study investigated the reliability and validity of the widely used 23-item Spiritual Transcendence Scale and tested whether there was factorial invariance of the scale by demographic variables such as gender, occupation, and religion in a large Chinese sample (n = 1,894). Exploratory factor analysis with a random subsample supported the original 3-factor structure (prayer fulfillment, universality, and connectedness) in a revised 16-item scale. Confirmatory factor analysis suggested that a 15-item model provided a good fit to the data of the remaining subsample. The scale had alpha reliabilities ranging from .64 to .92 in the exploratory factor analysis and .60 to .92 in the confirmatory factor analysis. Subsequent factorial invariance tests indicated that the scale was invariant across gender and occupation but not religion. Evidence of construct validity was equivocal. Additional empirical studies should be conducted to evaluate the psychometric properties of the scale in other culturally and religiously diverse settings.
