Conflict adaptation is reflected by response interference

The conflict monitoring theory suggests that the occurrence of conflict in previous trials leads to a reduction in interference in current trials through conflict adaption. The present study included two experiments that used a colour-based flanker task and a Stroop task in combination with a 2:1 stimulus-to-response mapping manipulation and a crossing of transition types (Previous trial type×Current trial type) with stimuli to investigate conflict adaption in relation to stimulus and response interference. The results demonstrate that response interference, but not stimulus interference, was reduced following both stimuli and response conflicts in previous trials. In contrast to some recent evidence, we conclude that conflict adaptation is limited to response interference.     

Developing Moral Decision-Making Competence: A Quasi-Experimental Intervention Study in the Swiss Armed Forces

Moral development has become an integral part in military training and the importance of moral judgment and behavior in military operations can hardly be overestimated. Many armed forces have integrated military ethics and moral decision-making interventions in their training programs. However, little is known about the effectiveness of these interventions. This study examined the effectiveness of a 1-week training program in moral decision making in the Swiss Armed Forces. The program was based on a strategy-based interactional moral dilemma approach. Results of this quasi-experimental intervention study showed significant improvements in content-related (moral and instrumental awareness, quality of moral information processing, development of compensatory actions) as well as process-related (situational analysis, development and evaluation of alternative solutions, justification of decision) aspects in moral decision making. Results of a follow-up test indicated positive long-term effects with regard to moral and instrumental awareness and process-related aspects. Findings are discussed, and consequences for leadership development programs and further research are explored.     

Teacher stress: An eight-year follow-up study on teachers' work,stress, and health

Abstract

The purpose of this study was to compare teacher stress between the years 1983 and 1991. Seventy teachers in comprehensive and upper secondary schools participated in the study. The teachers were studied first during the school year 1983–84 and again eight years later during the autumn term of 1991 by means of repeated questionnaires. During this 8-year period the general working situation among the teachers had remained quite stable: Most of them had remained at the same school teaching the same subjects at the same level. The results showed a drop in the teachers' well-being over the period. In particular, those over 55 years of age showed more emotional stress reactions in 1991 than eight years earlier. Furthermore, they evaluated their social relations with pupils as worse in 1991 compared to 1983. A half both of those with low emotional stress reactions and those high in them in 1983 were stilll in the same categories in 1991. Emotional stress reactions were reflected in simultaneous work ability and psychosomatic health data. Moreover, long-term stress was seen to lead to various psychosomatic complaints, but these were not reflected in self-rated health status. The results suggest that teacher stress is not necessarily a short-lived problem, and ways of preventing or reducing stress (e.g. continuing education, counseling, co-operation) should be employed.     

Daily fluctuations in teachers' well-being: a diary study using the Job Demands–Resources model

Abstract

The study tests the dynamic nature of the Job Demands–Resources model with regard to both motivational and health impairment processes. It does so by examining whether daily fluctuations in co-workers' support (i.e., a typical job resource) and daily fluctuations in work/family conflict (i.e., a typical job demand) predict day-levels of job satisfaction and mental health through work engagement and exhaustion, respectively. A total of 61 schoolteachers completed a general questionnaire and a daily survey over a period of five consecutive work days. Multilevel analyses provided evidence for both the above processes. Consistently with the hypotheses, our results showed that day-level work engagement mediated the impact of day-level co-workers' support on day-level job satisfaction and day-level mental health, after general levels of work engagement and outcome variables had been controlled for. Moreover, day-level exhaustion mediated the relationship between day-level work/family conflict and day-level job satisfaction and day-level mental health after general levels of exhaustion and outcome variables had been controlled for. These findings provide new insights into the dynamic psychological processes that determine daily fluctuations in employee well-being. Such insights may be transformed into job redesign strategies and other interventions designed to enhance work-related psychological well-being on a daily level.     

Where the Whole Thing Fell Apart

Abstract

This article examines the intersection of societal prejudice and psychological trauma. In an instrumental case study created through a layered narrative analysis, the author highlights the potentially traumatic effects of racism and discrimination, while also exploring the phenomenon of resilience in a complex ecological system. The findings suggest that the enduring and continual strain of racial prejudice may cause significant psychological distress, particularly when those experiences reinforce early negative experiences within a family; and that assessments of resilience need to consider the contribution of ecological context to psychological outcomes as well as to an individual's ability to mobilize personal resources when such a context finally shifts.     

Cognitive Control in the Face of Fear: Reduced Cognitive-Emotional Flexibility in Women with a History of Child Abuse

Child abuse can negatively affect neurobiological systems involved in regulating emotions. Adults who were maltreated as children show diminished capacity to flexibly integrate the prefrontal and limbic circuits underlying emotion regulation. Using a facial identification Stroop task with nonemotional and emotional stimuli, we found that women who reported more childhood abuse (N = 44) were no different from women reporting less childhood abuse (N = 45) on nonemotional conflict adaptation, but were significantly less able to adapt to emotional conflict. Women who reported more abuse were especially impaired in adapting to emotional conflict when incongruent stimuli involved a fearful face. These results help characterize the relation between cognitive control and emotion regulation and highlight the far-reaching effects of childhood abuse on cognitive-emotional flexibility.     

A Longitudinal Analysis of Loneliness Among Older People in Great Britain

Longitudinal studies of loneliness among older people are comparatively rare. At 8 years after the initial survey in 1999–2000, we followed up on the 999 people aged 65+ years who were living in the community in the United Kingdom. We found that 583 participants were still alive, and 287 (58%) participated in the follow-up survey. The overall prevalence of loneliness at both time points was very similar, with 9% reporting severe loneliness; 30% reporting that they were sometimes lonely, and 61% reporting that they were never lonely. We developed a 12-category typology to describe changes in loneliness across the follow-up period and report that 60% of participants had a stable loneliness rating, with 40–50% rating themselves as never lonely, and 20–25% rating themselves as persistently lonely; 25% demonstrated decreased loneliness, and approximately 15% demonstrated worse loneliness. Changes in loneliness were linked with changes in marital status, living arrangements, social networks, and physical health. Importantly improvements in physical health and improved social relationships were linked to reduced levels of loneliness. This result suggests that strategies to combat loneliness are not confined to the arena of social interventions such as befriending services, which aim to build and support social embeddedness, but may also result from the treatment of chronic and long-term health conditions.     

Effects of Cortical Lesions upon the Onset of Hoarding in Rats

Psychologists agree that play is an essential ingredient in a child's development. The present investigation evaluated the effects of an intensive period of dramatic play upon the cognitive structures of young children (N = 12 boys and girls, ages 3 to 5 years) using repertory grids to extract their systems of personal constructs. The period of dramatic play produced substantial and sustained improvements in the numbers of constructs, which confirms the importance of play in cognitive growth. The findings are also taken to support the value of drama therapy in bringing about cognitive change in the mentally ill.     

Development of Force Adaptation During Childhood

Humans learn to make reaching movements in novel dynamic environments by acquiring an internal motor model of their limb dynamics. Here, the authors investigated how 4- to 11-year-old children (N = 39) and adults (N = 7) adapted to changes in arm dynamics, and they examined whether those data support the view that the human brain acquires inverse dynamics models (IDM) during development. While external damping forces were applied, the children learned to perform goal-directed forearm flexion movements. After changes in damping, all children showed kinematic aftereffects indicative of a neural controller that still attempted to compensate the no longer existing damping force. With increasing age, the number of trials toward complete adaptation decreased. When damping was present, forearm paths were most perturbed and most variable in the youngest children but were improved in the older children. The findings indicate that the neural representations of limb dynamics are less precise in children and less stable in time than those of adults. Such controller instability might be a primary cause of the high kinematic variability observed in many motor tasks during childhood. Finally, the young children were not able to update those models at the same rate as the older children, who, in turn, adapted more slowly than adults. In conclusion, the ability to adapt to unknown forces is a developmental achievement. The present results are consistent with the view that the acquisition and modification of internal models of the limb dynamics form the basis of that adaptive process.
