Posttraumatic growth: why do people grow from their trauma?

In two experimental studies we found that participants who recalled a highly traumatic autobiographical event (trauma recall) compared with a lesser traumatic event (stress recall) reported having increasingly grown (posttraumatic growth, PTG). Moreover, participants who recalled a traumatic (vs. stressful) event perceived more death-related thoughts (Study 1) and reported coping with this event in a more emotion-focused and in a less problem-focused way (Study 2). Mediation analyzes revealed that the effect of trauma versus stress recall on PTG was mediated by emphasizing the positive, a subscale of emotion-focused coping. These results imply that growth resulting from traumatic events can be traced back to an illusion. No evidence was found that real PTG took place or that the effects shown resulted from death-related thoughts (terror management theory).     

Assessment of Situational Demands in a Selection Interview: Reflective style or sensitivity?

Correctly understanding situational demands is necessary to handle social situations appropriately. Past selection research has shown that candidates who are better at identifying the targeted dimensions in an interview or an assessment center, in fact, perform better in these procedures. However, at least two different processes might be responsible for the obtained findings. First, candidates might differ in their ability to correctly interpret given cues, meaning that some candidates generate better (i.e., more accurate) ideas than others. Second, some candidates might generally reflect more upon potential demands and therefore generate more ideas concerning potentially targeted dimensions. The present study used signal detection theory to investigate to what degree these two processes are related to interview performance. The interview was administered during a selection simulation for university graduates (N = 147). Interviewees' assumptions concerning the targeted dimensions were assessed in a postinterview questionnaire in which they had to write down any hypotheses as to what a certain question was trying to assess. We found that generating better ideas was essential for candidates' interview performance and not the degree to which they generally generated ideas about targeted interview dimension.     

Empirically based dimensions of externalizing symptoms in children and adolescents: a multitrait-multisource approach

The present study sought to refine knowledge about the structure underlying externalizing dimensions. From a “top-down” ICD/DSM-based perspective, externalizing symptoms can be categorized into attention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD). From a “bottom-up” developmental theory-based perspective, disruptive behaviors can be meaningfully described as aggressive (AGG) and rule-breaking (RB) behaviors. We analyzed five large data sets comprising externalizing symptom ratings obtained with a screening instrument using different sources (parents, teachers, self-ratings) from different samples. Using confirmatory factor analyses, we evaluated several factor models (unidimensional; correlated factors; bifactor (S-1) models) derived from an ICD/DSM- and theory-based perspective. Our optimally fitting models were assessed for measurement invariance across all sources, sample settings, and sex. Following several model-based criteria (model fit indices; factor loadings; omega statistics; model parsimony), we discarded our models stepwise and concluded that both the ICD/DSM-based model with three correlated factors (ADHD, ODD, CD) and the developmental theory-based model with three correlated factors (ADHD, AGG, RB) displayed a statistically sound factor structure and allowed for straightforward interpretability. Furthermore, these two models demonstrated metric invariance across all five samples and across sample settings (community, clinical), as well as scalar invariance across sources and sex. While the dimensions AGG and RB may depict a more empirically coherent view than the categorical perspective of ODD and CD, at this point we cannot clearly determine whether one perspective really outperforms the other. Implications for model selection according to our model-based criteria and clinical research are discussed.

     

Assessment of Callous-Unemotional Traits in 6 to 12 Year-Old Children with Oppositional Defiant Disorder/Conduct Disorder by Parent Ratings

The factorial structure of the Inventory of Callous-Unemotional Traits (ICU; Frick 2004) has been inconsistent across previous studies using different rater versions (self-report, parent, teacher) and versions in different languages applied to both clinical and nonreferred samples predominantly of adolescents. The present study examined the factorial structure of the parent-report version of the ICU in a clinical sample of boys aged 6–12 years with Oppositional Defiant Disorder/Conduct Disorder (n?=?131) using confirmatory factor analysis (CFA) and exploratory factor analysis (EFA). Results from the CFA supported previous findings, but even the preferred model with three independent factors (Callousness, Uncaring, and Unemotional) showed inadequate model fit. Subsequent EFA revealed a three-factor model consisting of two new subscales (Callousness/Lack of Guilt or Remorse, Unconcerned about Performance) and the original subscale Unemotional. Internal consistencies of the three subscales and total score were satisfactory, and intercorrelations of the subscales were weak, except for a moderate correlation between the subscales Callousness/Lack of Guilt or Remorse and Unconcerned about Performance. The corresponding subscales of the original and new versions were highly correlated. As expected, the ICU subscale Callousness/Lack of Guilt or Remorse showed associations with other measures of aggressive and oppositional behavior. The other two ICU subscales were not associated with aggression or oppositional/antisocial behavior, but Unconcerned about Performance correlated with a measure of attention problems and Unemotional correlated with the internalizing problem withdrawn. The implications of these findings are discussed, especially as a callous unemotional specifier for the diagnosis of Conduct Disorder is included in DSM-5.     

People performance enablers in relation to employees’ psychological attachment to the organisation

This study investigated the relationship between a set of people performance enablers and psychological attachment behavioural states in a variety of South African work settings. The sample (N?=?582) comprised mostly males (69%) and black Africans from organisations in the manufacturing (17%), financial services (14%), information technology (16%) and the non-profit sectors (53%). Data on employees’ perceptions of performance enablers and their psychological attachment to the particular organisation were collected using the Psychological Work Immersion Scale (PWIS: Veldsman, 2013 Veldsman, D. (2013). Moving towards a strategic human capital return on investment model: An exploratory study of the Psychological Work Immersion Scale. Unpublished research report, Rocketfuel Consulting, Randburg, South Africa. [Google Scholar]). The data were analysed using confirmatory factor analysis to reveal the structure of the people enablers and psychological attachment variables in the South African work settings. Structural equation modelling was used to predict psychological attachment from the performance enabler indicators. The findings provided evidence that employees’ perceptions of performance enablers significantly explain their level of psychological attachment (commitment, motivation and work absorption). Manager credibility appears as a key performance enabler and commitment as a strong element of psychological attachment. The research contributes to the literature on individual and organisational performance by extending research on work psychology in the South African context.     

How equivalent are the action execution,imagery, and observation of intransitive movements? Revisiting the concept of somatotopy during action simulation

Jeannerod (2001) hypothesized that action execution, imagery, and observation are functionally equivalent. This led to the major prediction that these motor states are based on the same action-specific and even effector-specific motor representations. The present study examined whether hand and foot movements are represented in a somatotopic manner during action execution, imagery, and action observation.     

The effect of hypnosis therapy on the symptoms and disease activity in Rheumatoid Arthritis

Abstract

The present study aimed to assess the effectiveness of clinical hypnosis on the symptoms and disease activity of Rheumatoid Arthritis (RA). Sixty six RA patients participated in a controlled group design. Twenty six patients learnt the hypnosis intervention, 20 patients were in a relaxation control group and 20 patients were in a waiting-list control group. During hypnosis, patients developed individual visual imagery aimed at reducing the autoimmune activity underlying the RA and at reducing the symptoms of joint pain, swelling and stiffness. Subjective assessments of symptom severity and body and joint function, using standardised questionnaires and visual analogue scales, were obtained. Objective measures of disease activity via multiple blood samples during the therapy period and at the two follow-ups were also taken. These measurements were of erythrocyte sedimentation rate. C-reactive protein, haemoglobin and leukocyte total numbers. Results indicate that the hypnosis therapy produced more significant improvements in both the subjective and objective measurements. above relaxation and medication. Improvements were also found to be of clinical significance and became even more significant when patients practised the hypnosis regularly during the follow-up periods.     

Moral prototypes and moral behavior: Specific effects on emotional precursors of moral behavior and on moral behavior by the activation of moral prototypes

The present studies investigated the extent to which three basic moral prototypes, “just,” “brave”, and “caring”, are related to moral, prosocial behavior. In five studies, we tested (a) whether people would associate three basic types of moral behavior (helping behavior, moral courage, and heroism) with three moral prototypes, and (b) whether specific emotional precursors of moral behavior and moral behavior itself could be promoted by activating the respective moral prototype. As expected, Studies 1–3 revealed that people associated helping behavior with the caring prototype, moral courage with the just prototype, and heroism with the brave prototype. Studies 4 and 5 showed that the activation of the three prototypes differentially influenced emotional precursors of the three types of moral behavior (Study 4) as well as actual moral behavior (Study 5). Thus, the five studies revealed that people associate different moral behaviors with different moral prototypes and that a certain moral behavior can be activated by the priming of the related prototype.

Strategies in visuospatial working memory for learning virtual shapes

This study investigated visuospatial working memory (WM) strategies people use to remember unfamiliar randomly generated shapes in the context of an interactive computer‐based visuospatial WM task. In a three‐phase experiment with random shapes, participants (n = 94) first interactively determined if two equivalent shapes were rotated or reflected; second, memorized the shape; and third, determined if an imprint in a profile view of the ground was a rotated, reflected imprint of the shape, or an imprint not matching the original shape. Participants self‐reported these strategies: Key feature, shape interaction, association/elaboration, holistic/perspective, divide and conquer, mental rotation/reflection and others. Participants reporting key features strategy were significantly more accurate on the computer‐based visuospatial WM task. These results highlight the importance of strategy in visuospatial WM.

Ceci n'est pas la mort: Evidence for the recruitment of self‐reference from surrealistic art under mortality salience

Previous research has demonstrated that death reminders influence how we perceive art. In the context of terror management theory, this has been explained by the death‐transcending quality of art to convey cultural meaning. In two studies, we examined psychological and neurocognitive responses to naturalistic and surrealistic art when death was primed. We found that naturalistic paintings were evaluated similarly in terms of personal reassurance in both mortality salience and control condition, whereas surrealistic paintings were evaluated as more reassuring in the mortality salience condition than in the control condition. Using high‐field functional magnetic resonance imaging in a second study, we found a similar pattern of results, showing specific activation in the precuneus, a brain area associated with self‐related operations, in all prime conditions for the viewing of naturalistic paintings, but only in the death and disgust prime conditions when viewing surrealistic paintings. Our results suggest motivated self‐reference when viewing both naturalistic and surrealistic artworks under mortality salience. Copyright © 2014 John Wiley & Sons, Ltd.
