Fatigue, cognitive functioning and psychological distress in Marfan syndrome, a pilot study

Marfan patients report fatigue as a major subjective complaint. We found no studies exploring the subject. The aim of this study was in a strictly defined Marfan population to assess self-reported fatigue, cognitive functions and psychological distress, correlations among them and correlations to visual acuity, joint hypermobility and use of beta-blockers. Sixteen subjects aged 18 - 30 years, fulfilling the Gent criteria, were assessed with the Fatigue Severity Scale, Fatigue Questionnaire, a comprehensive battery of neuropsychological tests and the General Health Questionnaire (GHQ). Self-reported fatigue was comparable with fatigue reported in other severe chronic diseases and disabilities, and was primarily in the mental/psychological domain. Psychological distress was higher than expected compared with the population at large. All neuropsychological test results were within the normal range, except for tests of visuo-motor coordination and speed of information processing. There was a significant inverse correlation between Fatigue Questionnaire ratings and some neuropsychological tests. Fatigue seems to be a serious problem for persons with Marfan syndrome and seems related to some areas of cognitive functioning. We found no overall impairment in cognitive functioning, but slightly reduced speed of information processing. Reduced visuo-motor coordination could be explained by impaired visual acuity.     

Contributions of Religious Actors to Peace and Security

The past decade has seen a shift of rhetoric, where religious actors are presented not just as aberrations in the secular and democratic order, but also as significant players in the development of peaceful and diversified societies. However, experiences of extremist religious groups raise questions about the legitimacy of involving religious actors in these kinds of processes, in particular in relation to security, which according to a classical perspective is a matter of national and international security agencies. This paper analyzes the challenges relating to the inclusion of religious actors in security situations in East Africa, particularly those involving confrontations between religious actors, in which the concept of the “religious other” has a specific reference. The main finding is that religious actors have a contribution to make in relation to security and conflict involving religion and faith, given that security is understood in a broader sense than the classical.     

Diplomacy and Psychology: Psychological Contributions to International Negotiations,Conflict Prevention,and World Peace

Psychological science has the potential to contribute to international diplomacy, and thereby indirectly to the prevention of conflicts between and within states that may escalate to wars. In this introduction of the Special Issue on Diplomacy and Psychology, different varieties of diplomacy are first briefly introduced. Then follows an enumeration of areas of psychological research that show the greatest promise of being directly or indirectly relevant to diplomacy. These research areas include judgement and decision making in negotiations and social dilemmas, social justice, intergroup conflicts, and intercultural processes. An additional area is research on environmental policy making, whose important role needs to be better recognized in international diplomacy. Overviews are also given of the articles included in the Special Issue.     

Respect,Coercion, and Religious Reasons

It is often assumed that people of faith should not endorse a law for religious reasons, since such an endorsement is considered to be disrespectful. Such a position is increasingly opposed by scholars who argue that such demands unjustifiably force people of faith to compromise their religious ideals. In order to defend their opposition to such demands, some scholars have invoked thought experiments as reductio arguments against the claim that endorsing laws dependent on religious reasons is necessarily disrespectful. I argue that these attempts have failed, and present an alternative thought experiment that demonstrates that such a law is not necessarily disrespectful. Because I conclude that previously proposed principles cannot defend this conclusion, I defend an alternative way of accommodating this intuition; a post‐secular deliberative approach based on the principle of double effect.     

Type of learning task impacts performance and strategy selection in decision making

In order to be adaptive, cognition requires knowledge about the statistical structure of the environment. We show that decision performance and the selection between cue-based and exemplar-based inference mechanisms can depend critically on how this knowledge is acquired. Two types of learning tasks are distinguished: learning by comparison, by which the decision maker learns which of two objects has a higher criterion value, and direct criterion learning, by which the decision maker learns an object's criterion value directly. In three experiments, participants were trained either with learning by comparison or with direct criterion learning and subsequently tested with paired-comparison, classification, and estimation tasks. Experiments 1 and 2 showed that although providing less information, learning by comparison led to better generalization (at test), both when generalizing to new objects and when the task format at test differed from the task format during training. Moreover, learning by comparison enabled participants to provide rather accurate continuous estimates. Computational modeling suggests that the advantage of learning by comparison is due to differences in strategy selection: whereas direct criterion learning fosters the reliance on exemplar processing, learning by comparison fosters cue-based mechanisms. The pattern in decision performance reversed when the task environment was changed from a linear (Experiments 1 and 2) to a nonlinear structure (Experiment 3), where direct criterion learning led to better decisions. Our results demonstrate the critical impact of learning conditions for the subsequent selection of decision strategies and highlight the key role of comparison processes in cognition.     

MPTinR: Analysis of multinomial processing tree models in R

We introduce MPTinR, a software package developed for the analysis of multinomial processing tree (MPT) models. MPT models represent a prominent class of cognitive measurement models for categorical data with applications in a wide variety of fields. MPTinR is the first software for the analysis of MPT models in the statistical programming language R, providing a modeling framework that is more flexible than standalone software packages. MPTinR also introduces important features such as (1) the ability to calculate the Fisher information approximation measure of model complexity for MPT models, (2) the ability to fit models for categorical data outside the MPT model class, such as signal detection models, (3) a function for model selection across a set of nested and nonnested candidate models (using several model selection indices), and (4) multicore fitting. MPTinR is available from the Comprehensive R Archive Network at http://cran.r-project.org/web/packages/MPTinR/.     

POST-TRAUMATIC STRESS REACTIONS AMONGST RESCUE WORKERS AFTER A MAJOR RAIL ACCIDENT

Abstract

Rescue tasks under heavy strain may act as traumatic events creating stress reactions among the rescue workers. After a major rail accident the rescue workers were examined by questionnaire at 3 and 7 months postaccident using the General Health Questionnaire-28 (GHQ), Impact of Event Scale (IES) and a structured questionnaire made for the purpose. Eighteen percent of the 77 rescue workers who participated in the study had GHQ-case-score and 10% had IES-case-score at 7 months using the usual GHQ-cut-off (4/5) and a low IES-cut-off (19/20). For the case-scorers there was a tendency towards increased GHQ- and IES-scores from 3 to 7 months. Five (6%) had post-traumatic stress disorders (PTSD) of low to moderate severity at 7 months.     

Suppression of negative and expression of positive emotions: Divergent effects of emotional display rules in a hostile service interaction

Cross-sectional studies have found that demands to express positive emotions have more desirable associations with service providers' well-being and service quality than demands to suppress negative emotions. Despite their potential importance, emotional labour research has not clarified the nature of these differences yet. The present experimental study aimed to investigate the causal effects of demands to suppress negative emotions, demands to express positive emotions, and their interaction in a simulated service interaction. In total, 101 participants were instructed to play the role of a service employee, who had to interact with a dissatisfied and uncivil customer. Participants were randomly given information that the organization expected them to (1) express genuinely felt emotions, (2) suppress negative emotions, (3) express positive emotions, or (4) suppress negative emotions and express positive emotions. Results confirmed that demands to suppress negative emotions decreased well-being, whereas demands to express positive emotions led to a better service quality. Moreover, service quality was only increased if demands to express positive emotions were not supplemented by demands to suppress negative emotions. These findings suggest that not only demands to express positive emotions can reduce the cost/benefit ratio of emotional labour, but also organizations should avoid imposing demands to suppress negative emotions.     

Variations of the past. Reflections on memory in contemporary psychoanalysis

In Jewish thought, contradictory positions may be legitimate. This is seen in Freud´s position in relation to tradition and memory: remembrance is valuable, but so is a movement forward. The main claim of this paper is that psychoanalysis in this respect has changed. While in especially the early Freudian position, one could see a stress on the importance of going back to earlier times, object relation theory mainly stresses the importance of facilitating new functions. This change has been especially clear during the last two decades. As cases of example, the use of neurocognitive models in psychoanalysis as well as Fonagy’s theory are discussed. The consequences of the shift from a bidirectional to a unidirectional, forward-looking, psychoanalysis, are discussed.
