Music acquisition: effects of enculturation and formal training on development

Musical structure is complex, consisting of a small set of elements that combine to form hierarchical levels of pitch and temporal structure according to grammatical rules. As with language, different systems use different elements and rules for combination. Drawing on recent findings, we propose that music acquisition begins with basic features, such as peripheral frequency-coding mechanisms and multisensory timing connections, and proceeds through enculturation, whereby everyday exposure to a particular music system creates, in a systematic order of acquisition, culture-specific brain structures and representations. Finally, we propose that formal musical training invokes domain-specific processes that affect salience of musical input and the amount of cortical tissue devoted to its processing, as well as domain-general processes of attention and executive functioning.     

Body image and explicit and implicit anti-fat attitudes: the mediating role of physical appearance comparisons

Prejudice against overweight people is rife. However, there is a paucity of research on the underlying reasons for it. In two studies the relationship between body image, the tendency to make physical appearance-related comparisons (PACS), and both explicit and implicit anti-fat attitudes was examined. In Study 1 (n = 227) people with a high tendency to make physical appearance-related comparisons (high PACS scorers) reported lower self-appearance evaluation, but higher appearance orientation and explicit anti-fat attitudes. The PACS fully mediated the relationship between appearance orientation and explicit anti-fat attitudes. Study 2 (n = 134) found that the PACS also mediated the relationship between appearance orientation and implicit anti-fat attitudes. Thus, individual differences in factors such as body image and the tendency to make appearance-related comparisons, appear to play a central role in both explicit and implicit anti-fat attitudes.     

Hypermnesia: Age-related differences between young and older adults

Hypermnesia is a net improvement in memory performance that occurs across tests in a multitest paradigm with only one study session. Our goal was to identify possible age-related differences in hypermnesic recall. We observed hypermnesia for young adults using verbal (Experiment 1) as well as pictorial (Experiment 2) material, but no hypermnesia for older adults in either experiment. We found no age-related difference in reminiscence (Experiments 1 and 2), though there was a substantial difference in intertest forgetting (Experiments 1 and 2). Older, relative to young, adults produced more forgetting, most of which occurred between Tests 1 and 2 (Experiments 1 and 2). Furthermore, older, relative to young, adults produced more intrusions. We failed to identify a relationship between intrusions and intertest forgetting. We suggest that the age-related difference in intertest forgetting may be due to less efficient reinstatement of cues at test by older adults. The present findings reveal that intertest forgetting plays a critical role in hypermnesic recall, particularly for older adults.     

Playing the Woman Card: Ambivalent Sexism in the 2016 U.S. Presidential Race

Late in the 2016 U.S. Presidential primary, Donald Trump attacked Hillary Clinton for playing the “woman’s card.” Theories of system justification suggest that attitudes about gender, particularly endorsement of hostile and benevolent sexism, likely shaped reactions to this campaign attack. Using a set of two studies, we find that hostile sexists exposed to the attack showed increased support for Trump and decreased support for Clinton. Benevolent sexists, however, reacted to Trump’s statements with increased support for Clinton, consistent with benevolent sexism’s focus on protecting women (Study 1). We further found that the woman card attack produced distinct emotional reactions among those with low and high levels of hostile and benevolent sexism. The attack also increased political participation among hostile sexists (Study 2). Our results offer new insights into the role of sexism in the 2016 presidential contest and further the discipline’s understanding of the gendered dimension of negative campaigning.     

Using self-evaluation to improve difficult-to-read handwriting of secondary students

We used delayed multiple-baseline and multiple-probe techniques to assess the effects of self-evaluation training on the legibility of cursive handwriting. Five secondary special education students with difficult-to-read handwriting served as participants. All participants improved the legibility of their handwriting during self-evaluation training. A systematic withdrawal of the training package demonstrated maintenance of treatment effects. For the most part, the students' handwriting remained at least 90% legible to judges following the systematic withdrawal of the self-evaluation training.     

阅读中自然学习生词的实验研究

本研究对儿童阅读时从语境中自然学习生词的过程及其多个影响因素进行了探讨。301名三、五年级小学生参加了实验。首先要求他们阅读文章,然后测验他们对文章中生词的知识。本研究在不同年级和能力的儿童中都发现了显著的自然学习效应。结果还表明,词的概念难度、词结构的语义透明度、语境线索强度和儿童课外阅读量对儿童的自然学习有重要影响。     

Sensitive Topics,Missing Data,and Refusal in Social Network Studies: An Ethical Examination

We describe our ethics‐driven process of addressing missing data within a social network study about accountability for racism, classism, sexism, heterosexism, cis‐sexism, ableism, and other forms of oppression among social justice union organizers. During data collection, some would‐be participants did not return emails and others explicitly refused to engage in the research. All refusals came from women of color. We faced an ethical dilemma: Should we continue to seek participation from those who had not yet responded, with the hopes of recruiting more women of color from within the network so their perspectives would not be tokenized? Or, should we stop asking those who had been contacted multiple times, which would compromise the social network data and analysis? We delineate ways in which current discussions of the ethics of social network studies fell short, given our framework and our community psychology (CP ) values. We outline literature that was helpful in thinking through this challenge; we looked outside of CP to the decolonization literature on refusal. Lessons learned include listening for the possible meanings of refusals and considering the level of engagement and the labor required of participants when designing research studies.
