Using stressful films to analyze risk factors for PTSD in analogue experimental studies – which film works best?

Abstract

To understand mental disorders, analogue paradigms provide an indispensable contribution. In posttraumatic stress disorder (PTSD), the stressful film paradigm is a frequently used analogue approach: Films depicting traumatic events are shown to non-clinical participants in order to elicit stress responses analogue to responses to traumatic events in real life. Previous studies used a large variety of films, which is problematic with regard to the comparability of results. The main goal of this study was to identify a film clip that (a) consistently provokes stress reactions and (b) provokes reactions that are as similar as possible to traumatic stress.

We randomly exposed 105 male and female participants to one of four stressful films, differing, e.g., in content and origin. Intrusive memories of the film, reported immediately after the film and during a diary phase of three days, as well as distress, heart rate, and several mood states were measured. A film clip depicting rape elicited the most consistent reactions that were characterized by a higher heart rate, more distress and more intrusive memories, compared to the other three clips. Intrusive memories across all films were especially related to an increase in heart rate and disgust in response to the film.     

Psychotherapy with children in refugee families who have survived torture: Containment and understanding of repetitive behaviour and play

Children of refugee families who have survived torture often have emotional, psychosomatic and behavioural problems as well as problems with learning. In order to understand the difficulties of these children, we have to recognize the complicated interaction of cumulative traumatic strain and recurring exposure to shocking violence. The traumatic experiences of the child in the country of origin take place in the broader context of chronic danger and persecution, often to be followed in the country of exile both by recurrent family strain and social estrangement. In the transference this complicated mixture of repeated trauma and chronic strain may show as a pervasive tendency to retreat to defensive survival strategies combined with continual repetition of more specific traces of the impact of the trauma on the individual. This paper focuses on how the enacted survival strategies can be contained and understood in the transference. In due course the compulsive repetition can be given meaning as a precondition for better integration through symbolic thought and self-understanding.     

Theistic Multiverse and Slippery Slopes: A Response to Klaas Kraay

Abstract

Most recently, Klaas Kraay has argued that God could have created a subset of all logically possible universes, the member universes of which are chosen by God due to their axiological status. In the present paper, we first argue that Kraay fails in developing an axiological basis for his theistic multiverse. In particular, we demonstrate that science provides no evidence for a multiverse constituted only by universes above a certain axiological threshold. In the second part of this paper, we argue that the idea of the theistic multiverse might be made fruitful in the context of Open Theism.     

Self-esteem and the Dual Processing of Interpersonal Contingencies

Social cognitive research has shown that individuals with low self-esteem exhibit contingency expectations involving interpersonal acceptance and rejection (e.g., If I fail, then I will be rejected). We examined whether the processing differences between low and high self-esteem individuals would be evident in their most spontaneous reactions, or only in relatively deliberate responses. A lexical decision task measured people's reaction times to positive or negative interpersonal words, following success or failure primes. The stimulus onset asynchrony was manipulated to allow spontaneous or deliberate processing. Individuals with low self-esteem exhibited contingencies at the spontaneous level. These contingencies were not evident in individuals with high self-esteem. The findings support interpersonal models of self-esteem, and confirm that controlled, deliberate thought is not required for the activation of relational expectations.     

Multidimensionality of Well-Being and Spillover Effects Across Life Domains: How Do Parenthood and Personality Affect Changes in Domain-Specific Satisfaction?

Whether having children improves our well-being is a long-standing topic of debate. Demographic and sociological research has investigated changes in individuals’ overall well-being and partnership satisfaction when they become parents. However, little is known about how becoming parent may produce vulnerability—observable as an enduring decrease in well-being—in life domains that are strongly interdependent with the family domain, such as work and leisure. Linking life-course and personality psychology perspectives, the authors examine the trajectories of subjective well-being—measured as satisfaction with life, work, and leisure—3 years before and 3 years after the transition to parenthood. The authors particularly focus on the moderating effects of gender and personality. Using data from the German Socio-Economic Panel (1984–2013) and multilevel growth curve modeling, the authors show strong gender-based vulnerability in how people react to parenthood. Although men display a nonlinear pathway of decreasing life satisfaction and a stable trajectory of job satisfaction, women experience more changes in their satisfaction with work and more dramatic decreases in leisure satisfaction. Contrary to most of our expectations, the moderating effects of personality were modest. Extraversion influenced the trajectories of work satisfaction, whereas neuroticism and conscientiousness affected the pathway of leisure satisfaction for women only. This article shows that the transition to parenthood influences well-being trajectories in specific domains, and this influence differs between women and men.     

Functional magnetic resonance imaging study of Piaget's conservation-of-number task in preschool and school-age children: a neo-Piagetian approach

Jean Piaget’s theory is a central reference point in the study of logico-mathematical development in children. One of the most famous Piagetian tasks is number conservation. Failures and successes in this task reveal two fundamental stages in children’s thinking and judgment, shifting at approximately 7 years of age from visuospatial intuition to number conservation. In the current study, preschool children (nonconservers, 5-6 years of age) and school-age children (conservers, 9-10 years of age) were presented with Piaget’s conservation-of-number task and monitored by functional magnetic resonance imaging (fMRI). The cognitive change allowing children to access conservation was shown to be related to the neural contribution of a bilateral parietofrontal network involved in numerical and executive functions. These fMRI results highlight how the behavioral and cognitive stages Piaget formulated during the 20th century manifest in the brain with age.     

Emotional plasticity: conditions and effects of improving emotional competence in adulthood

This study aimed to investigate (a) whether it is possible to increase emotional competence (EC) in adulthood; (b) whether this improvement results in better mental, physical, and social adjustment; (c) whether this improvement can be maintained 1 year later; and (d) whether these benefits are accompanied by a reduction in stress-hormone secretion (i.e., cortisol). One hundred and thirty-two participants were randomly assigned to an EC-enhancing intervention (in group format) or to a control group. Participants in the intervention group underwent a specifically designed 15-hr intervention targeting the 5 core emotional competencies, complemented with a 4-week e-mail follow-up. Results reveal that the level of emotional competencies increased significantly in the intervention group in contrast with the control group. This increase resulted in lower cortisol secretion, enhanced subjective and physical well-being, as well as improved quality of social and marital relationships in the intervention group. No significant change occurred in the control group. Peer reports on EC and quality of relationships confirmed these results. These data suggest that emotional competencies can be improved, with effective benefits on personal and interpersonal functioning lasting for at least 1 year. The theoretical implications of these results as well as their practical implications for the construction and the development of effective emotional competencies interventions are discussed.     

Using the Black Sheep Effect to reveal normative stakes: The example of alcohol drinking contexts

The present study shows that the paradigm relative to Black Sheep Effect (BSE) may be used to reveal normative stakes whose existence is not clearly identified. To this end, our study focuses on alcohol drinking practices among students, specifically with regard to drinking contexts (solitary vs. group). Our hypothesis was that the drinking norms are determined by their context (i.e. social vs. solitary drinking). More specifically, we suggested that social drinking is viewed by students as pro‐normative, while solitary drinking is viewed as anti‐normative. The results confirmed our hypotheses and enable us to consider that the BSE paradigm has the potential to reveal normative stakes. Copyright © 2010 John Wiley & Sons, Ltd.     

The paddle move commonly used in magic tricks as a means for analysing the perceptual limits of combined motion trajectories

Following Gustav Kuhn's inspiring technique of using magicians' acts as a source of insight into cognitive sciences, we used the 'paddle move' for testing the psychophysics of combined movement trajectories. The paddle move is a standard technique in magic consisting of a combined rotating and tilting movement. Careful control of the mutual speed parameters of the two movements makes it possible to inhibit the perception of the rotation, letting the 'magic' effect emerge--a sudden change of the tilted object. By using 3-D animated computer graphics we analysed the interaction of different angular speeds and the object shape/size parameters in evoking this motion disappearance effect. An angular speed of 540 degrees s(-1) (1.5 rev. s(-1)) sufficed to inhibit the perception of the rotary movement with the smallest object showing the strongest effect. 90.7% of the 172 participants were not able to perceive the rotary movement at an angular speed of 1125 degrees s(-1) (3.125 rev. s(-1)). Further analysis by multiple linear regression revealed major influences on the effectiveness of the magic trick of object height and object area, demonstrating the applicability of analysing key factors of magic tricks to reveal limits of the perceptual system.
