Mind the Gaps: Are Conclusions About Mindfulness Entirely Conclusive?

Mindfulness has emerged as an important construct in the mental health field. Although evidence suggests benefits, it also appears that excitement over the clinical applications of mindfulness has largely suspended concentrated efforts to clarify fundamental elements of the construct. This article explores conceptual confusion and contrasts primary mindfulness‐based techniques before investigating attrition factors, adverse effects of mindfulness practices, and populations contraindicated for mindfulness‐based techniques. Implications for practice are provided.     

A pilot study of women’s affective responses to common and uncommon forms of aerobic exercise

Objective: To test the extent to which participants exposed to an uncommon versus common exercise stimulus would result in more favourable affect at post-task.

Design: Experimental design. Participants (N = 120), American women aged 18–45 years, were randomly assigned to complete 30-min of either the uncommon (HOOP; n = 58) or common (WALK; n = 62) exercise stimulus.

Main outcome measures: Self-reported affect and intentions for future exercise were measured before and after the 30-min exercise bout.

Results: Analyses of covariance were run to compare post-task affect across the HOOP and WALK conditions. At post-task, participants assigned to HOOP reported more positively valenced affect, higher ratings of positive activated affect, lower ratings of negative deactivated affect, and stronger intentions for future aerobic exercise compared to participants assigned to WALK.

Conclusions: Participants who completed an uncommon bout of aerobic exercise (HOOP) reported more favourable affect post-exercise, as well as stronger intentions for future exercise, compared to participants who completed a common bout of aerobic exercise (WALK). Future work using a longitudinal design is needed to understand the relationships between familiarity with an exercise stimulus, affective responses to exercise, motivation for future exercise behaviour and exercise maintenance over time.     

Sexual Nature? (Re)presenting Sexuality and Science in the Museum

The past 15 years have seen dramatic changes in social norms around sex and sexuality in the UK and worldwide. In 2011, the London Natural History Museum (NHM) contributed to these debates by opening the temporary exhibition Sexual Nature, which aimed to provide ‘a candid exploration of sex in the natural world’ whilst also drawing in an under-represented audience of young adults. Sexual Nature provides an opportunity to explore Macdonald's ‘politics of display’ in the mutual construction of (public) scientific knowledge, society and sexuality, at a time of intense contestation over sexual norms. Whilst Sexual Nature both reflected and contributed to major reframings of sexuality and what science can say about it, the assumption that it would be possible to present this topic as morally neutral, reliable and uncontested, in line with traditions of public science, proved to be problematic. The language of the exhibition moved back and forth between human/animal similarity and difference, and between scientific and cultural tropes as the NHM tried to maintain epistemic authority whilst also negotiating the moral boundaries of acceptable sexual behaviour. The topic of sex pushed the museum far beyond its usual expertise in the natural sciences towards the unfamiliar territory of the social and human, resulting in an ad hoc search for, and negotiation with, alternative sources of expertise. Boon et al.’s co-curation approach to exhibition building has the potential to extend the NHM's audience-driven strategy, whilst also producing a more coherent and nuanced exhibition about the science of sex.     

Similarity to the self influences cortical recruitment during impression formation

Prior work has shown that whether or not someone is similar to the self influences person memory—a type of self-reference effect for others. In this study, we were interested in understanding the neural regions supporting the generation of impressions and subsequent memory for targets who vary in similarity to the self. Participants underwent fMRI scanning while forming positive or negative impressions of face–behavior pairs. We tested participants’ memory for their generated impressions and then back-sorted the impression trials (encoding) into different levels of self-similarity (high, medium, low) using a self-similarity posttest that came after recognition. Extending prior behavioral work, our data confirmed our hypothesis that memory would be highest for self-similar others and lowest for self-dissimilar others. Dorsal anterior cingulate cortex (dACC) activity increased with self-similarity (high > medium > low) to targets, regardless of later memory for them. An analysis of regions supporting impression memory revealed a double dissociation within medial temporal lobe regions: for similar others, amygdala recruitment supported memory, whereas for dissimilar others, hippocampal activation supported memory. These results suggest that self-similarity influences evaluation and memory for targets but also affects the underlying neural resources engaged when thinking about others who vary in self-similarity.     

Linguistic and prosodic aspects of child-directed speech: The role of maternal child-rearing experiences

This study explored if the quality of mothers’ reported child-rearing experiences influences the prosodic and linguistic features of maternal child-directed speech. Lexical, syntactic, functional and prosodic aspects of maternal speech directed towards their 24-month-old children were examined. Results showed that mothers with different child-rearing histories differed in the ways they talked to their children. Mothers who recalled the caregiving they received during childhood as characterized by high levels of care and low levels of control, used a lexically and syntactically more complex speech and expressed more positive emotions. This kind of input seems to be more attuned with the typical growing skills of two-year-old children. Implications for the study of mother–infant relationship as well as for the study of child language development are addressed.

Are reporting errors due to encoding limitations or retrieval failure? Surveys of child vaccination as a case study

Surveys of childhood vaccinations are often highly inaccurate, due to parental misreporting. We conducted three experiments to examine the source of the inaccuracies. In Experiment 1, we provided parents with memory aids; these aids did little to improve reporting accuracy. Two further experiments asked whether parents forgot what they knew about their children's vaccinations, or whether they never knew the information. In Experiment 2 we surveyed parents both immediately and ten weeks after their child's medical visit. Accuracy was only slightly better than chance immediately afterwards; ten weeks later performance had not changed significantly. Experiment 3 compared reports in both recall and recognition conditions. Although the recognition condition lowered the response burden on parents it did not produce more accurate reports. We conclude that low levels of accuracy in parental reports on vaccinations appear to reflect poor initial encoding rather than retrieval failure. Copyright © 1999 John Wiley & Sons, Ltd.     

Processing focus structure and implicit prosody during reading: differential ERP effects

Several recent studies have shown that focus structural representations influence syntactic processing during reading, while other studies have shown that implicit prosody plays an important role in the understanding of written language. Up until now, the relationship between these two processes has been mostly disregarded. The present study disentangles the roles of focus structure and accent placement in reading by reporting event-related brain potential (ERP) data on the processing of contrastive ellipses. The results reveal a positive-going waveform (350-1300 ms) that correlates with focus structural processing and a negativity (450-650 ms) interpreted as the correlate of implicit prosodic processing. The results suggest that the assignment of focus as well as accent placement are obligatory processes during reading.     

We Believe in Being Honest: Examining Subcultural Differences in the Acceptability of Deception1

Perceptions of lie acceptability vary as a function of the motivation for the lie, the relationship between deceiver and deceived, and the perceiver's cultural background. The current study examines the relation between one cultural background—that is, the Church of Jesus Christ of Latter‐Day Saints (LDS)—and perceptions of lie acceptability, and whether this varies as a function of lie and rater characteristics. Participants rated lie acceptability in 12 scenarios varying lie motivation and lie recipient. Overall, the LDS group rated lies as less acceptable than did the non‐LDS group, and lie acceptability varied according to lie motivation and lie recipient. Participant age was negatively correlated with lie acceptability. Implications of the findings and directions for future research are discussed.     

Multicultural experience enhances creativity: the when and how

Many practices aimed at cultivating multicultural competence in educational and organizational settings (e.g., exchange programs, diversity education in college, diversity management at work) assume that multicultural experience fosters creativity. In line with this assumption, the research reported in this article is the first to empirically demonstrate that exposure to multiple cultures in and of itself can enhance creativity. Overall, the authors found that extensiveness of multicultural experiences was positively related to both creative performance (insight learning, remote association, and idea generation) and creativity-supporting cognitive processes (retrieval of unconventional knowledge, recruitment of ideas from unfamiliar cultures for creative idea expansion). Furthermore, their studies showed that the serendipitous creative benefits resulting from multicultural experiences may depend on the extent to which individuals open themselves to foreign cultures, and that creativity is facilitated in contexts that deemphasize the need for firm answers or existential concerns. The authors discuss the implications of their findings for promoting creativity in increasingly global learning and work environments.
