Intrusive images and intrusive thoughts as different phenomena: Two experimental studies

According to the dual representation theory of PTSD, intrusive trauma images and intrusive verbal thoughts are produced by separate memory systems. In a previous article it was shown that after watching an aversive film, participants in non-movement conditions reported more intrusive images than participants in a free-to-move control condition (Hagenaars, Van Minnen, Holmes, Brewin, & Hoogduin, 2008). The present study investigates whether the experimental conditions of the Hagenaars et al. study had a different effect on intrusive thoughts than on intrusive images. Experiment 2 further investigated the image–thoughts distinction by manipulating stimulus valence (trauma film versus neutral film) and assessing the subsequent development of intrusive images and thoughts. In addition, both experiments studied the impact of peri-traumatic emotions on subsequent intrusive images and thoughts frequency across conditions. Results showed that experimental manipulations (non-movement and trauma film) caused higher levels of intrusive images relative to control conditions (free movement and neutral film) but they did not affect intrusive thoughts. Peri-traumatic anxiety and horror were associated with subsequent higher levels of intrusive images, but not intrusive thoughts. Correlations were inconclusive for anger and sadness. The results suggest intrusive images and thoughts can be manipulated independently and as such can be considered different phenomena.     

The role of standing in the psychology of procedural justice: Towards theoretical integration

In the current chapter, the authors explore the relation between social standing and procedural justice. Standing is an important construct in procedural justice theories and tends to be broadly defined as the position that people have in social groups. It is argued that the standing construct suffers from conceptual ambiguity: In procedural justice literature two distinct interpretations of standing can be distinguished, one defining standing as intragroup status and one defining standing as the extent to which people are included in social groups. Furthermore, it is argued that research findings on the relation between standing and procedural justice are not conclusive. The authors review recent empirical findings that address these concerns, and conceptually integrate these findings. In closing, the authors outline avenues for future research that the procedural justice field may want to take, and discuss implications of the work reviewed here.     

Physical distancing during the COVID-19 crisis: The roles of threat and moralization

One reason why the COVID-19 pandemic presented a challenge to public health is that individuals struggled to adhere to virus protective behaviors, such as physical distancing. To aid understanding why people engaged in distancing practices, we investigated the role of threat perceptions and the moralization of physical distancing. We collected longitudinal data from 340 US citizens across five measurement waves from April 2020 to June 2021. Results showed that individuals who perceived COVID-19 as more threatening, and those who more strongly moralized physical distancing, were more likely to engage in physical distancing behavior. Moreover, the effect of threat perceptions on physical distancing behavior was mediated by moralization of physical distancing. These results provide new insights into the adherence to physical distancing behaviors during pandemics and underscore the importance of moralization in shaping behavior.     

Competitive Memory Training for treating depression and rumination in depressed older adults: a randomized controlled trial

Although rumination is an important mediator of depressive symptoms, there is insufficient proof that an intervention that specifically targets rumination ameliorates the clinical condition of, depressed patients. This study investigates whether a time-limited cognitive behavioral intervention (Competitive Memory Training, or COMET for depressive rumination) is an effective treatment for depression and rumination. This intervention was tested in older adult depressed outpatients. A total of 93 patients (aged ≥65 years with major depression and suffering from rumination) were treated in small groups according to the COMET protocol in addition to their regular treatment. Patients were randomized to two treatment conditions: 7 weeks of COMET + treatment-as-usual (TAU) versus TAU only. COMET + TAU showed a significant improvement in depression and rumination compared with TAU alone. This study shows that the transdiagnostic COMET protocol for depressive rumination might also be successful in treating depression and rumination in older adults.     

Should I save or should I not kill? How people solve moral dilemmas depends on which rule is most accessible

The literature on how people solve moral dilemmas often focuses on situations in which individuals have to make a decision where different moral rules are in conflict. In some of these situations, such as in footbridge dilemmas, people have to choose between sacrificing a few people in order to save many. The present research focuses on how people decide what to do in dilemmas involving conflicting moral rules. We propose that the rule that is cognitively most accessible during the decision making process (e.g., “Save lives” or “Do not kill”) will influence how people solve these moral dilemmas. Three studies are reported that indeed demonstrate that the most accessible rule influences willingness to intervene within footbridge dilemmas. This effect is found even when the accessibility of the rule is induced subliminally.     

Guiding trustful behavior: The role of accessible content and accessibility experiences

Trust has been identified as a key ingredient to the prosperity of close relationships, organizations, and societies. While research mainly focused on the antecedents and consequences of trust, much less is known about how individuals assess whether there are enough reasons to warrant trustful action. Two experiments explored the how and when of this assessment, suggesting that antecedents may not only be integrated as content information per se (as generally assumed), but in a feeling‐based summary form. Specifically, our results show that the ease or difficulty associated with the identification of antecedents to trust may guide trustful behavior. Furthermore, it is shown that such a feeling‐based influence is particularly likely to occur in conditions of personal certainty. Together these results extend prior research in the domains of trust and economic games, and further attest to the fundamental role cognitive feelings play in social life.

Assessing the Incremental Algorithm: A Response to Krahmer et al.

This response discusses the experiment reported in Krahmer et al.’s Letter to the Editor of Cognitive Science. We observe that their results do not tell us whether the Incremental Algorithm is better or worse than its competitors, and we speculate about implications for reference in complex domains, and for learning from ‘‘normal” (i.e., non‐semantically‐balanced) corpora.     

Model-guided implementation of an instrument for program evaluation: The use of social policy and innovation models

A research program in the Netherlands is aimed at the implementation of an instrument for program evaluation in organizations for intramural treatment of juveniles with psychosocial and/or behavioral problems. The basis and guide for the implementation is a sequence of three complementary models, each model being more specific than its predecessor. The results of the research program in nine organizations suggest that the choice of an adequate guiding model depends on the policy level at which the organization is operating, the number of persons involved in the implementation, and the culture of decision-making in the organization. K. Mesman Schultz is senior investigator at the Leyden Institute for Social Policy Research (LISPOR) and director of the Research Centre for Youth-at-Risk (RCY) at the State University of Leyden, Rijnsburgerweg 100, 233 AE Leiden The Netherlands. His research mainly refers to diagnosis, decision-making and social policy in the field of youth care. W.I. Poot is investigator at LISPOR and RCY. She is in charge of the execution of utilization and implementation research projects in the field of youth care. P.H.M. van den Bogaart is senior investigator at LISPOR and RCY.

Culture and Gender Differences in the Perception of Friendship by Adolescents

This study examines personal collectivism and individualism (or allocentrism and idiocentrism) in relation to the perception of same-sex friendships among adolescents living in a multi-ethnic context in the Netherlands. Respondents originally from collectivist cultures were more allocentric than respondents originally from individualist cultures. Among the former group allocentrism was unrelated to idiocentrism, whereas a negative relation was found among the latter group. Allocentrism was related to a greater sensitivity to friends, using more ascribed features in describing friends, having fewer friends but seeing their relationship as closer, perceiving less intimacy with other-than-best-friends, and endorsing rules about relations with third parties more. Idiocentrism was related to less sensitivity to friends, using more personal characteristics in describing friends, but also to having fewer friends, talking less intimately with others, and endorsing friendship rules about intimacy less. Additionally, gender had independent effects on the perception of friendship, suggesting that cultural and gender differences cannot be characterized by the same set of features.
