How do conspiratorial explanations differ from non-conspiratorial explanations? A content analysis of real-world online articles

The present research aims to identify unique characteristics of written conspiracy theories. In two pre-registered quantitative human-coded content analyses, we compared 36 pairs of conspiratorial and non-conspiratorial online articles about various events. As predicted, conspiratorial articles—compared to non-conspiratorial articles—contained less factual, more emotional and more threat-related information. Also, we predicted and found that conspiratorial articles presented more argumentation against the opposing standpoint and that they provided explanations that were more dispositional and less falsifiable. Contrary to our predictions, we did not consistently observe that conspiratorial articles presented less argumentation for their own standpoint. Also, we did not find consistent support that conspiratorial articles provided less information about the specific process or more information about the underlying goals of the respective events, or that conspiratorial explanations attributed the events to a lesser extent to situational factors. We discuss the relevance of our findings for the understanding of conspiracy theories.     

A program for parsing mouse movements into component submovements

Most current movement control theories include the idea that movement toward a target can be broken into several submovements. The complexity of analyzing a movement into its constituent submovement structure and the additional complexity imposed by the problem of noise in the data and hand tremor seem to be daunting to researchers. This paper discusses a program that can ameliorate both of these problems and parse movements into their constituent submovements. It also contains a graphing feature that is useful as a visual tool for analyzing submovement structure. The programs are easily modifiable, so that researchers can specify their own parsing rules on the basis of different assumptions about movement control and use the parser for data from different experimental tasks.     

Reading about explanations enhances perceptions of inevitability and foreseeability: a cross-cultural study with Wikipedia articles

In hindsight, people often perceive events to be more inevitable and foreseeable than in foresight. According to Causal Model Theory (Nestler et al. in J Exp Psychol Learn Mem Cogn 34: 1043–1054, 2008), causal explanations are crucial for such hindsight distortions to occur. The present study provides further empirical support for this notion but extends previous findings in several ways. First, ecologically valid materials were used. Second, the effect of causal information on hindsight distortions was investigated in the realm of previously known events. Third, cross-cultural differences in reasoning (analytic vs. holistic) were taken into account. Specifically, German and Vietnamese participants in our study were presented with Wikipedia articles about the nuclear power plant in Fukushima Daiichi, Japan. They read either the version that existed before the nuclear disaster unfolded (Version 1) or the article that existed 8 weeks after the catastrophe commenced (Version 2). Only the latter contained elaborations on causal antecedents and therefore provided an explanation for the disaster. Reading that version led participants to perceive the nuclear disaster to be more likely inevitable and foreseeable when compared to reading Version 1. Cultural background did not exert a significant effect on these perceptions. Hence, hindsight distortions were obtained for ecologically valid materials even if the event was already known. Implications and directions for future research are discussed.     

Black identity and workplace oppression

This paper is primarily aimed at counselling and psychotherapy practitioners who meet issues of workplace conflict in their practice and the resulting stress and trauma faced by their clients. I define workplace conflict as complex and enduring situations arising from diverse forms of harassment. These include bullying, scapegoating and other discriminatory and oppressive practices that affect health, esteem and work performance. This paper reports the findings from my doctoral research project which investigated and sought to understand the specific experience and nature of workplace conflict for black workers in three institutional settings: the National Health Service (NHS), education and social services. The inspiration for this research came from psychotherapy practice, where it was repeatedly observed that black workers appeared to be suffering significantly more negative and damaging effects of workplace stress and trauma than white workers. I describe these experiences as workplace oppression and differentiate them from other workplace conflicts.

"Dwelling in the Past": The Role of Rumination in the Treatment of Posttraumatic Stress Disorder

Prolonged exposure, a cognitive behavioral therapy including both in vivo and imaginal exposure to the traumatic memory, is one of several empirically supported treatments for chronic posttraumatic stress disorder (PTSD). In this article, we provide a case illustration in which this well-validated treatment did not yield expected clinical gains for a client with PTSD and co-occurring major depression. After providing an overview of the literature, theory, and treatment protocol, we discuss the clinical cascade effect that underlying ruminative processes had on the treatment of this case. Specifically, we highlight how ruminative processes, focusing on trying to understand why the traumatic event happened and why the client was still suffering, resulted in profound emotional distress in session and in a lack of an "optimal dose" of exposure during treatment.     

Mental reinstatement of context and return of fear in spider-fearful participants

Extant findings in the animal and human conditioning literature demonstrate that renewal, termed return of fear in studies with humans, occurs when reexposure to a previously feared phobic stimulus occurs in a context different than the one present during extinction. The present study investigated whether mental reinstatement of the treatment context at follow-up could attenuate context-based return of fear. Forty-eight spider-fearful individuals received exposure therapy in one of two contexts, and were followed-up 1 week later in the treatment or a new context. Half of the participants received instructions to mentally reinstate the treatment context before the follow-up test. Self-report data replicated previous research on contextually driven return of fear. Furthermore, participants who mentally reinstated the treatment context, before encountering the phobic stimulus in a new context at follow-up, had less return of fear than those who did not. Limitations of the current study, as well as implications for phobia treatment, are discussed.     

Parent Stress and Coping: Waiting for a Child to Receive a Kidney Transplant

The current study examined the degree of parent stress and depression among mothers and fathers of children with end-stage renal disease (ESRD) listed for a kidney transplant, to determine whether demographic factors, stress, and coping would predict parent depression. Eighty-six mothers and 58 fathers of children with ESRD preparing for a kidney transplant completed standardized measures of parent stress related to the child’s chronic illness (PIP), coping style (Brief Cope), and depression (BDI-II). Information about the disease was obtained from the medical record. Maternal depression was predicted by having a lower family income, higher degree of parent stress associated with the child’s illness, and the use of avoidant coping strategies. Paternal depression was only predicted by higher parent stress. Illness related variables did not contribute significantly to the understanding of parent outcomes. Pre-transplant evaluations should screen for elevated levels of stress and depression, and develop interventions to help parents cope with their child’s renal disease.
