Psychobiology of mindfulness

There is controversy about whether mindfulness-based approaches to psychotherapy represent a new wave of cognitive-behavioral therapy or a core process in all psychotherapies. One way of conceptualizing mindfulness is in terms of emotion regulation; mindfulness is a strategy aimed at opposing suppression and avoidance. Dispositional mindfulness has been associated with greater activation in prefrontal cortex and greater deactivation of amygdala during affect labeling. A number of rigorous studies of mindfulness-based cognitive therapy for depression have been positive. However, much remains to be discovered about the underlying mechanisms of and clinical indications for mindfulness-based approaches.     

Cognitive performance and morning levels of salivary cortisol and alpha-amylase in children reporting high vs. low daily stress perception

The aim of the present study was to assess the effects of daily stress perception on cognitive performance and morning basal salivary cortisol and alpha-amylase levels in healthy children aged 9-12. Participants were classified by whether they had low daily perceived stress (LPS, n = 27) or a high daily perceived stress (HPS, n = 26) using the Children Daily Stress Inventory (CDSI). Salivary cortisol and alpha-amylase were measured at awakening and 30 minutes later. Cognitive performance was assessed using the Cognitive Drug Research assessment system. The HPS group exhibited significantly poorer scores on speed of memory (p < .05) and continuity of attention (p < .05) relative to the LPS group. The HPS group also showed significantly lower morning cortisol levels at awakening and at +30 minutes measures in comparison with the LPS group (p < .05), and mean morning cortisol levels were negatively correlated with speed of memory (p < .05) in the 53 participants. No significant differences were observed between both groups in alpha-amylase levels. These findings suggest that daily perceived stress in children may impoverish cognitive performance via its modulating effects on the HPA axis activity.     

Differences in perceptions on sexual and reproductive health between service providers and people living with HIV: a qualitative elicitation study

The sexual and reproductive health (SRH)-related needs of people living with HIV/AIDS (PLHA) have not been sufficiently recognised in research and clinical care. Fifteen study sites in 13 European countries participated in this qualitative study to assess differences in perceptions between service providers (SP) and PLHA on SRH-related problems and needs of PLHA. Factors influencing SRH were determined to collect evidence on how to improve service provision. Qualitative data were obtained using an interpretative ethnographical approach. Data were analysed inductively on country level; a cross country data matrix was developed to facilitate the contextual analysis. Thirty-seven FGD discussions were organised with a total of 254 participants. A short survey was distributed to assess demographic characteristics. Results revealed insufficient information and lack of behavioural skills regarding SRH issues among PLHA. Intra- and interpersonal, provider-related, and social factors were found to influence the SRH behaviours of PLHA. Although from patients' perception SRH is a prioritized issue, it rarely comes up during routine HIV clinical care. SP need adequate counseling training to tackle SRH-related issues. A better integration between HIV care programs and SRH care settings is needed to improve effective service provision.     

Do wild New Caledonian crows (<Emphasis Type="Italic">Corvus moneduloides</Emphasis>) attend to the functional properties of their tools?

New Caledonian crows are the most proficient non-hominin tool manufacturers but the cognition behind their remarkable skills remains largely unknown. Here we investigate if they attend to the functional properties of the tools that they routinely use in the wild. Pandanus tools have natural barbs along one edge that enable them to function as hooking implements when the barbs face backwards from the working tip. In experiment 1 we presented eight crows with either a non-functional (‘upside-down’) or a functional pandanus tool in a baited hole. Four of the crows never flipped the tools. The behaviour of the four flipping birds suggested that they had a strategy of flipping a tool when it was not working. Observations of two of the eight crows picking up pandanus tools at feeding tables in the wild supported the lack of attention to barb direction. In experiment 2 we gave six of the eight crows a choice of either a barbed or a barbless pandanus tool. Five of the crows chose tools at random, which further supported the findings in experiment 1 that the crows paid little or no attention to the barbs. In contrast, a third experiment found that seven out of eight crows flipped non-functional stick tools significantly more than functional ones. Our findings indicate that the crows do not consistently attend to the presence or orientation of barbs on pandanus tools. Successful pandanus tool use in the wild seems to rely on behavioural strategies formed through associative learning, including procedural knowledge about the sequence of operations required to make a successful pandanus tool.

Study on the relations between temperament,aggression, and anger in children

The present work analyzes the relationships between the dimensions of temperament and the exteriorized emotions of aggression and anger. Temperament was assessed by mothers using the Dimensions of Temperament Survey‐Revised, while aggression and anger were self‐reported by the children using the Scale of physical and Verbal Aggression and the State–Trait Anger Expression Inventory for Children. The sample studied was made up of 293 children (49.83% boys; 50.17% girls) with a mean age of 11.13 years. The results showed that temperamental difficulties give rise to exteriorized emotions, especially anger. Predictive values of temperament on aggression and anger ranged from 1% to 7% of explained variance. Aggr. Behav. 32:207–215, 2006. © 2006 Wiley‐Liss, Inc.     

Dimensionality of rosenberg’s self-esteem scale among normal-technical stream students in Singapore

Dimensionality of the widely used Rosenberg’s Self-Esteem Scale (RSES) was investigated in a sample of 153 seventh-grade Asian students from Singapore. Confirmatory factor analyses performed on the scores of the RSES revealed two factors (positive and negative self-esteem) as hypothesized. Both factors were empirically related to different external variables. Results from multiple regression analyses indicated that positive self-esteem significantly predicted students’ mastery goal orientation and academic self-efficacy scores while negative self-esteem significantly predicted students’ disruptive behavior. These findings provide some preliminary support that the two factors could possibly be measuring substantively distinct dimensions, thus calling into question the unidimensionalty of the RSES in an Asian school-based sample. This study was supported by a grant from Center for Research in Pedagogy and Practice, National Institute of Education (CRP 26/04 RA) to Rebecca P. Ang.     

Are members of low status groups perceived as bad, or badly off? Egalitarian negative associations and automatic prejudice

Three studies explored the hypothesis that implicit measures of prejudice can tap negative, yet egalitarian associations. In Study 1, automatically associating African Americans with oppression predicted greater automatic prejudice. In Studies 2 and 3, classically conditioning associations between the novel group Noffians and words like oppressed, maltreated, and victimized led to greater automatic prejudice against Noffians. Results suggest that White Americans’ negative automatic associations with African Americans may partly result from associating members of low status groups with unfair circumstances. Because automatic associations predict prejudiced behaviors, the burden of proof is on those wishing to argue that egalitarian negative associations complicate the assessment of automatic attitudes rather than contribute to prejudiced responses. Discussion focuses on the implications of egalitarian negative associations for the theory and measurement of automatic prejudice.     

Socio-demographic conditions, subjective somatic health, Axis I disorders and personality disorders in the common population: the relationship to quality of life

Quality of life (QOL) was studied in a population of 2,065 subjects in Norway. A broad concept of QOL was applied, including subjective well-being, self-realization, negative life events, and a number of interpersonal relationships. The assessment of QOL, based on interview, was related to a number of socio-demographic variables, subjectively experienced somatic health, the most common Axis I disorders, and all Axis II personality disorders (PDs). The results of multivariate analyses showed that being female and living with a partner in the outskirts of a city and having good physical health are important positive correlates of QOL. Controlling for all these variables, major depression, dysthymic disorder, and somatoform disorders were the Axis I disorders that have a negative statistical effect on global QOL. Specific anxiety disorders did not add to the effects. Among the PDs, avoidant, schizotypal, paranoid, and schizoid PD traits were the most important statistical negative determinants of QOL, followed by borderline, dependent, antisocial, and also self-defeating and narcissistic PDs, restricted to some specific sub-indexes of QOL. The study also showed that our results vary and are sometimes the opposite, depending on the sub-index of QOL examined. The study showed that it is necessary to apply a broad concept of QOL to disclose the real nature or the relationship between mental disorders and QOL. Furthermore, demographic variables, subjectively experienced somatic health, Axis I disorders, and PD traits appeared to be independently associated with QOL.
