Can self-affirmation exacerbate adverse reactions to stress under certain conditions?

Objective: Self-affirmation has repeatedly been shown to reduce adverse psychological and physiological responses to stress. However, it is plausible that self-affirmation could exacerbate negative reactions to stress under certain conditions. The current research explored whether self-affirmation would increase negative psychological responses to a stressor occurring in a central life domain characterised by low levels of control.

Design: Female participants (Study 1 N = 132; Study 2 N = 141) completed baseline measures of anxiety and mood. They were then randomly allocated to complete a self-affirmation or control task, before reading a narrative documenting a stressful birth and imagining themselves in the place of the woman giving birth. After completing this task, participants again reported their levels of anxiety and positive mood.

Main outcome measures: Anxiety and positive mood assessed at follow-up.

Results: Study 1 demonstrated that self-affirmed women experienced increased anxiety and less positive mood at follow-up, compared both to baseline and to women in the control condition. Study 2 revealed that the effect of self-affirmation on outcomes was moderated by fear of childbirth.

Conclusion: These results provide preliminary evidence that self-affirmation may worsen negative responses to stressors under certain conditions and for certain individuals.     

White-matter microstructure and language lateralization in left-handers: A whole-brain MRI analysis

Most people are left-hemisphere dominant for language. However the neuroanatomy of language lateralization is not fully understood. By combining functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI), we studied whether language lateralization is associated with cerebral white-matter (WM) microstructure. Sixteen healthy, left-handed women aged 20–25 were included in the study. Left-handers were targeted in order to increase the chances of involving subjects with atypical language lateralization. Language lateralization was determined by fMRI using a verbal fluency paradigm. Tract-based spatial statistics analysis of DTI data was applied to test for WM microstructural correlates of language lateralization across the whole brain. Fractional anisotropy and mean diffusivity were used as indicators of WM microstructural organization. Right-hemispheric language dominance was associated with reduced microstructural integrity of the left superior longitudinal fasciculus and left-sided parietal lobe WM. In left-handed women, reduced integrity of the left-sided language related tracts may be closely linked to the development of right hemispheric language dominance. Our results may offer new insights into language lateralization and structure–function relationships in human language system.     

Procedural Fairness and Creativity: Does Voice Maintain People's Creative Vein Over Time?

Although some research suggests a link between procedural fairness and creativity, so far no study has directly tested whether a real manipulation of procedural fairness affects creativity. Additionally, research on procedural fairness effects consists mostly of unique studies, but more realistic, life-like longitudinal experiments with repeated fairness manipulations are lacking. This study investigated the influence of procedural fairness (i.e., having voice) on similar creativity tasks over a period of 4 weeks. Participants in the fair procedure condition maintained their level of creativity during the course of the experiment, whereas participants who were treated unfairly showed a decline in creativity. This research confirms the supporting role of conditions of procedural fairness regarding creativity and the importance of longitudinal designs to fully explore procedural fairness effects.     

Young adult female fragile X premutation carriers show age- and genetically-modulated cognitive impairments

The high frequency of the fragile X premutation in the general population and its emerging neurocognitive implications highlight the need to investigate the effects of the premutation on lifespan cognitive development. Until recently, cognitive function in fragile X premutation carriers (fXPCs) was presumed to be unaffected by the mutation. Here we show that young adult female fXPCs show subtle, yet significant, age- and FMR1 gene mutation-modulated cognitive impairments as tested by a quantitative magnitude comparison task. Our results begin to define the neurocognitive endophenotype associated with the premutation in adults, who are at risk for developing a neurodegenerative disorder associated with the fragile X premutation. Results from the present study may potentially be applied toward the design of early interventions wherein we might be able to target premutation carriers most at risk for degeneration for preventive treatment.     

Empowerment to participate: a case study of participation by indian sex workers in HIV prevention

The popularity of ‘participation’ and ‘empowerment’ in international development discourse is not matched by sophisticated conceptualisation of these terms. Critics have argued that their vagueness allows ‘participation’ and ‘empowerment’ to be used indiscriminately to describe interventions which vary from tokenism to genuine devolving of power to the community. This paper suggests that conceptualising empowerment and participation simply in terms of a scale of ‘more or less’ participation or ‘more or less’ empowerment does not capture the qualitatively different forms of empowerment that are necessary for different activities. Instead, the paper conceptualises participation in terms of concrete domains of action in which people may be empowered to take part. An ethnographic case study of a participatory HIV prevention project run by sex workers in Kolkata illustrates the argument. Four domains of activity in which sex workers may participate are distinguished: (1) participating in accessing project services; (2) participating in providing project services; (3) participating in shaping project workers' activity; (4) participating in defining project goals. To be empowered to participate in each domain depends upon a different set of resources. Asking the question ‘empowerment to do what?’ of health promotion projects is proposed as a way of facilitating appropriate project design. Copyright © 2006 John Wiley & Sons, Ltd.

Synaesthesia,creativity and art: What is the link?

It has been suggested that individuals with synaesthesia may show heightened creativity as a result of being able to form meaningful associations between disparate stimuli (e.g. colour, sound). In this study, a large sample (N=82) of people with various kinds of synaesthesia were given two psychometric tests of creativity (Remote Associates Test, Alternate Uses Test) and were also asked about the amount of time engaged in creative arts (visual art, music). There was a significant tendency for synaesthetes to spend more time engaged in creative arts and this was, at least in part, dependent upon the type of synaesthesia experienced. For example, synaesthetes experiencing vision from music were far more likely to play an instrument than their other synaesthetic counterparts. There was no relationship between this tendency and the psychometric measures of creativity, but synaesthetes did outperform controls on one of the two psychometric measures (Remote Associates). We conclude that the tendency for synaesthetes to be more engaged in art is likely to have a different mechanism to psychometric measures of creativity, and that there is no direct link between them. Although synaesthetes may well perform better on some measures of creativity, we suggest that synaesthetes have better bottom‐up access to certain associations, but are not necessarily better able to use them flexibly (in divergent thinking).     

Weight‐Based Discrimination in Occupational Hiring and Helping Behavior1

This study explored weight‐based discrimination using a range of weight categories, as represented by images of real women with known body mass index (BMI). In the first study, 30 men rated each image according to likelihood of occupational hiring for a managerial post. In the second study, 28 men rated the same images for likelihood of helping behavior following a minor accident. Study results showed that individuals with a slender body weight (BMI = 19–20) were most likely to be hired and helped, while obese (BMI > 30) participants were least likely to be hired and helped. However, results also showed that emaciated (BMI < 15) individuals were likely to be discriminated against. Implications for real‐life settings are discussed.     

The Social Conditions for Successful Peer Education: A Comparison of Two HIV Prevention Programs Run by Sex Workers in India and South Africa

Peer education is a community-based intervention being implemented worldwide as an approach to HIV prevention. However, its results are inconsistent, with little consensus on why some projects succeed while others fail. Considering peer education as an ‘intervention-in-context’, we systematically compare the context and the implementation of two peer education interventions run by sex workers, one in India and one in South Africa, which produced contrasting outcomes. In so doing, we aim to identify key factors in the projects’ successes or failures that may inform future peer education efforts. The Indian project’s relative success was facilitated (1) by a more stable and supportive social, material and political context, and (2) by a community development ethos which devoted significant resources to sex workers’ involvement, ownership and empowerment, as opposed to a biomedical approach which marginalised sex workers’ concerns. We conclude with lessons learned and implications for current trends in peer education.
