Feeling time in nature: The influence of directed and undirected attention on time awareness

In the present study, we examined the impact of the interaction of environmental and task-induced attentional focus on time perception, specifically awareness of the time flow. We tested 48 participants in either a natural or urban setting over three 25- to 35-min sessions. We manipulated the within-subjects factor task by means of two tasks—one requiring directed attention on the task itself, the other undirected attention on the environment—alongside a control condition with no specific task. We measured time awareness, passage of time judgments, felt time judgments, and estimated time as dependent variables. For time awareness, we found an interaction between environment and task: in the natural environment, only a task requiring directed attention reduced time awareness; whereas, in the urban environment, both tasks reduced time awareness compared to the control condition. The results suggest that natural environments increase time awareness unless we focus our attention on a task.     

Persistence and relapse of reinforced behavioral variability

The present study examined persistence and relapse of reinforced behavioral variability in pigeons. Pigeons emitted four‐response sequences across two keys. Sequences produced food according to a lag schedule, in which a response sequence was followed by food if it differed from a certain number of previous sequences. In Experiment 1, food was delivered for sequences that satisfied a lag schedule in both components of a multiple schedule. When reinforcement was removed for one component (i.e., extinction), levels of behavioral variability decreased for only that component. In Experiment 2, food was delivered for sequences satisfying a lag schedule in one component of a multiple schedule. In the other component, food was delivered at the same rate, but without the lag variability requirement (i.e., yoked). Following extinction, levels of behavioral variability returned to baseline for both components after response‐independent food delivery (i.e., reinstatement). In Experiment 3, one group of pigeons responded on a lag variability schedule, and the other group responded on a lag repetition schedule. For both groups, levels of behavioral variability increased when alternative reinforcement was suspended (i.e., resurgence). In each experiment, we observed some evidence for extinction‐induced response variability and for variability as an operant dimension of behavior.     

Comparing different boosters of planning interventions on changes in fat consumption in overweight and obese individuals: A randomized controlled trial

Single planning interventions have been found to promote short‐term dietary change. Repeated planning interventions may foster long‐term effects on behavior change. It remains unknown whether there is a critical number of boosters to establish long‐term maintenance of behavioral changes. This study aimed at investigating what social‐cognitive variables mediate the effects of the interventions on dietary behavior change. Overall, 373 participants (n = 270 women, 72.4%; age M = 52.42, SD = 12.79) were randomly allocated to one of five groups: a control group, a single planning group, and three groups with 3, 6, or 9 weeks’ repeated planning interventions. Follow‐ups took place 4, 6, and 12 months after baseline. Change in fat consumption was not promoted by any of the interventions. In terms of social‐cognitive variables, intentions, self‐efficacy and coping planning displayed a time × group interaction, with the 9 weeks’ planning group showing the most beneficial effects. Effect sizes, however, were very small. None of the tested planning interventions successfully promoted change in fat consumption across the 12 month period. This, however, could not be explained by problems with adherence to the intervention protocol. Potential explanations for this unexpected result are discussed.     

The interplay of received social support and self-regulatory factors in smoking cessation

Objective: In smoking cessation, individual self-regulation and social support have both proven to be useful. However, the roles of self-regulatory processes and social support are mostly examined separately. The present study aims at examining the unique and joint interactive effects of self-regulation as specified in the health action process approach (HAPA) and social support on smoking cessation. The study tested whether social support can compensate for low levels of self-regulation or whether synergistic effects emerge.

Design & Measures: Around a self-set quit date, 99 smokers completed baseline questionnaires on HAPA-variables, smoking-specific received social support and smoking cessation (continuous abstinence and point prevalence), with a follow-up Cpproximately 29?days after the quitdate.

Results: Social support moderated the association between volitional self-efficacy and smoking, as well as coping planning and smoking but not between action planning and smoking. No compensatory effect of social support for lower levels of individual regulation emerged but the combination of high levels of the individual variables and social support was related to successful smoking cessation, indicating a synergistic effect.

Conclusions: The results confirm the importance of examining both self-regulation and social factors in smoking cessation. This should be considered when developing future interventions for smoking cessation.     

Keeping adolescents safe from harm: management strategies of African-American families in a high-risk community

In this study, we investigated changes in parents' use of restrictive and promotive management strategies from early to middle adolescence. We also examined the antecedents of these changes and their effects on adolescents' achievement and mental health. Longitudinal data included 50 African American adolescents and their parents living in a low-income school district. There were three major findings. First, parents, on average, used less restrictive and promotive management strategies from early to middle adolescence. Second, parents who experienced increased depressive symptoms reported using more restrictive management strategies from early to middle adolescence. Third, adolescents whose parents increased their use of restrictive management strategies experienced more anger and lower grade point averages, whereas adolescents whose parents increased their use of promotive management strategies experienced less anger, higher grade point averages, and less absences from early to middle adolescence. These findings suggest that increasing parents' use of promotive rather than restrictive management strategies may be more beneficial in supporting the academic achievement and mental health of adolescents living in high-risk neighborhoods.     

After the Fall of the Wall: The Impact of the Transition on East German Women

This article addresses the impact of unification on East German families and on the situation of women in the East. The main hypothesis is that women are the losers of German unification, not only in terms of their decreasing participation in the labor force, but also in terms of their weakened position in partnerships and their increasing responsibilities in the domestic sphere. The findings are based primarily on personal interviews of different types of families. The first part of the article describes respondents' recollections of their everyday lives during the days of the former DDR (East Germany) and analyzes the specific family structures and relations between family members that prevailed. It focuses on the domestic division of labor and discusses the impact of high female employment on gender roles in the family and in the socialist society. The second part deals with the effects of German unification on families in East Germany.     

Psychische Faktoren gastrointestinaler Erkrankungen

The list of potential or proven associations between psychological and intestinal functions in healthy subjects and in patients with functional and organic bowel disorders demonstrates that although these associations are manifold they are to a large extent incompletely understood, primarily of academic interest and not yet ready to be integrated into everyday clinical practice. However, of immediate practical relevance are psychotherapeutic as well as psychopharmacological approaches. It is, however, required that clinicians, both medical and psychological, are aware of the mechanisms of regulation of intestinal functions through central (CNS) and peripheral (ENS) neural circuits.
