A disgust mood state causes a negative interpretation bias, but not in the specific domain of body-related concerns

The present study was designed to examine the effects of a disgust mood state on negative interpretation bias, in particular in the domain of body and weight concerns. Participants (N = 120) were randomly assigned to one of four mood induction groups (i.e., disgust, anxiety, happy, and neutral) and were afterwards asked to respond to various types of ambiguous scenarios to index general threat interpretations, negative body-related interpretations, and neutral/positive interpretations. Results demonstrated that both the anxiety and disgust mood induction groups displayed higher levels of negative interpretations of the ambiguous threat scenarios than the neutral and happy groups. However, no evidence was obtained for a negative interpretation bias in the body-related domain for these negative mood groups, and this conclusion was also true for participants scoring high on a scale of eating disorder symptoms. Altogether, these findings suggest that disgust does not play a role in eating pathology by inducing a negative interpretation bias in the specific domain of body and weight concerns.     

Executive function and weight status in children: A one-year longitudinal perspective

There is considerable evidence for an association between obesity and impaired executive function (EF) in adolescents and adults. However, little research has examined EF in overweight or obese children. Furthermore, data on EF in underweight individuals is lacking. In addition, there is no consensus on the directionality of the relationship between Body Mass Index (BMI) and EF, and longitudinal studies are rare. Thus, the present study examined whether children differ in their performance on a battery of EF tasks depending on their weight status (underweight, normal-weight, overweight), and investigated the longitudinal cross-lagged associations between EF and BMI. Hot EF (delay of gratification, affective decision-making), cool EF (attention shifting, inhibition, working memory [WM] updating), and BMI were assessed in 1,657 German elementary-school children at two time points, approximately one year apart. Overweight children exhibited slightly poorer attention shifting, WM updating, and affective decision-making abilities as compared to normal-weight children. Unexpectedly, they did not show any deficits in inhibition or delay of gratification. EF levels of underweight children did not differ significantly from those of normal-weight children. Furthermore, poor attention shifting and enhanced affective decision-making predicted a slightly higher BMI one year later, and a higher BMI also predicted poorer attention shifting and WM updating one year later. The latter association between BMI and subsequent EF scores, however, diminished when controlling for socioeconomic status. Results indicate that hot and cool EF plays a role in the weight development of children, and might be a promising factor to address in preventive interventions.     

Erfassung der sozialen Ungleichheit in empirischen Untersuchungen

Background

The interrelationship between social inequality and health problems is well known. This paper evaluates how current empirical studies in the context of social psychiatry, psychosomatics and medical sociology respond to this issue in terms of taking characteristics of socio-economic status (SES) into account.

Material and methods

All empirical studies published in the German journals Psychotherapie, Psychosomatik und Medizinische Psychologie and Psychiatrische Praxis in 2005 and 2006 were evaluated regarding the use of characteristics of SES.

Results

Of the 113 studies examined, 70 (62%) covered characteristics of the SES. The majority included characteristics of both formal and professional education, but often in only few categories. Some studies used a combination of formal and professional education. Half of the studies included categories of occupational status or gainful employment, also often in few categories and 11% of studies included net family income. Three studies formed an index of social class using the categories lower class, middle class and upper class.

Conclusion

Determination of characteristics of SES can be improved both quantitatively and qualitatively. Comparability of population studies can be improved by an increased orientation on demographic standards.     

Theory-of-mind, cognitive development, and children's interpretation of anxiety-related physical symptoms

The present study investigated developmental patterns in children's interpretation of anxiety-related physical symptoms and emotional reasoning, and to what extent these phenomena are influenced by children's level of cognitive development. A large sample of 4-13-year-old children (N=358) were exposed to vignettes in which the presence and absence of physical symptoms was systematically varied. In addition, children completed a series of conservation tasks and a theory-of-mind-test. Results demonstrated that from the age of 7, children were increasingly able to link physical symptoms to anxiety. Furthermore, cognitive development appeared to enhance children's ability to interpret physical symptoms as a sign of anxiety. Further, children's tendency to infer danger from vignettes with physical symptoms (i.e., emotional reasoning) was already prominent in 4-6-year-olds. The implications for physical symptom-based theories of childhood anxiety are briefly discussed.     

The role of functional information for infant categorization

This report examines whether knowledge about function influences the formation of artifact categories in 11-12- month old infants. Using an object-examination task, a set of artificial stimuli was presented that could either be grouped according to overall similarity or according to similarity in one functionally relevant part. Experiment 1 revealed that infants categorized the objects according to overall similarity but not part similarity under control conditions. Experiment 2 showed that after having seen the experimenter demonstrating the functional use of the critical part, infants later categorized the stimuli according to part similarity. When the same actions were performed without producing any effect, infants failed to categorize according to the critical part. This set of findings suggests that 11-12-month old infants use functional information as a cue to categorization.     

Post-traumatic growth and optimism as outcomes of an internet-based intervention for complicated grief

This explorative study examines the effects of an internet-based cognitive-behavioural therapy for complicated grief on post-traumatic growth and optimism. The study is part of a larger randomized controlled trial described in Wagner, Knaevelsrud, and Maercker (2006). The patients were randomly assigned to either a treatment group (n = 26) or a waiting list control condition (n = 25). The internet-based intervention consisted of exposure to bereavement cues, cognitive reappraisal exercises, and a module on integration and restoration. A short form of the Post-traumatic Growth Inventory (PTGI), the Life Orientation Test-Revised (LOT-R), and measures of complicated grief and psychopathological outcomes were administered. Results indicate that post-traumatic growth increased in the treatment group. No treatment effect was found for optimism. These findings contribute to the growing literature on personal growth in psychotherapy.

Cause or effect: What matters? How 12‐month‐old infants learn to categorize artifacts

This paper investigates the role of cause and effect relations for infants' learning about artifacts. Two experiments tested whether 12‐month‐olds categorized a given set of unfamiliar artifacts according to overall similarity and/or according to part similarity, depending on what kind of video demonstration was presented before the start of the categorization task. In both experiments, the actions performed with objects were accompanied by interesting effects but the causal relation between object‐structure and effects was teased apart. In one video demonstration (Expt 1), the experimenter used the object part to produce some kind of effect in a causally plausible way. In another video demonstration (Expt 2), the experimenter performed similar actions with the same objects as in Expt 1, followed by the same effects as before. Importantly, however, no plausible cause–effect relation was provided this time. Only infants participating in Expt 1 categorized the set of unfamiliar objects according to part similarity. This finding suggests that 12‐month‐olds attend to the causal relation between specific object parts and their functional use when categorizing artifacts, rather than merely associating form‐characteristics with an interesting effect.     

A Multi-Level Approach to Direct and Indirect Relationships between Organizational Voice Climate,Team Manager Openness,Implicit Voice Theories,and Silence

Employee silence impedes sustainable organizational development, and it can conceal harm for internal and external stakeholders. Established approaches to overcoming silence in organizations draw on the assumption that employees withhold their views based on deliberate elaborations on the effectiveness and risks they associate with voice. Our research aims at complementing these approaches. Applying an information processing approach to culture and using implicit voice theories (IVTs; i.e., taken-for-granted beliefs about when and why speaking up at work is risky or inappropriate) as an example, we introduce a model proposing ways through which shared implicit knowledge structures emerge in teams and organizations, and how they affect motives to remain silent. We examine parts of the model with a sample of 696 employees nested in 129 teams and 67 organizations. Our findings show that IVTs can be shared at the team and organizational level, that shared IVTs explain variance in silence motives above and beyond perceptions of organizational climate and manager openness at the team and organization level, and that IVTs function as a mediator between team manager openness and silence motives. In sum, our findings point at shared IVTs as a way to conceptualize underlying basic assumptions of cultures of silence.
