Heart work after errors: Behavioral adjustment following error commission involves cardiac effort

Posterror slowing (PES) is the observation that people respond slower on trials subsequent to error commissions than on trials subsequent to correct responses. Different accounts have been proposed to explain PES. On the one hand, it has been suggested that PES arises from an adaptive increase in cognitive control following error commission, thereby making people more cautious after making an error. On the other hand, PES has been attributed to an orienting response, indicating that attention is shifted toward the error. In the present study we tested these accounts by investigating the effects of error commission in both flanker and switch tasks on two task-evoked cardiac measures: the interbeat interval—that is, the interval between two consecutive R peaks—and the RZ interval—that is, the interval between the R peak and the Z point—as measured using electro- and impedance cardiography, respectively. These measures allowed us to measure cardiac deceleration (autonomic orienting) and cardiac effort mobilization, respectively. Our results revealed a shorter RZ interval during posterror trials, indicating increased effort mobilization following errors. In addition, we replicated earlier studies that have shown cardiac slowing during error trials. However, multilevel analyses showed that only the posterror decrease in RZ interval predicted posterror reaction times, whereas there was no positive relationship between error-related cardiac deceleration and posterror reaction times. Our results suggest that PES is related to increased cardiac effort, supporting a cognitive-control account of PES.     

Emotional intelligence (EI), conflict resolution patterns,and relationship satisfaction: Actor and partner effects revisited

This study tested for actor and partner effects in the relationship between ability-based EI and adaptive marital relationships and satisfaction employing a standard dyadic design involving 100 young heterosexual couples. Participants were assessed on the MSCEIT along with measures of conflict resolution patterns and perceived marital satisfaction. A series of path analyses provided support for actor effects—but not partner effects—in the association of EI, assessed as ability, and marital variables. Overall, the data provide only partial support for the common claim and some prior research suggesting that EI plays a pivotal role in marital relationships.     

Toward a Conceptualist Solution of the Grounding Problem

This paper defends a conceptualist answer to the question how objects come by their modal properties. It isolates the controversial metaphysical assumptions that are needed to get ontological conceptualism off the ground, outlines the conceptualist answer to the question and shows that conceptualism is not in as bad a shape as some critics have maintained.     

Is knowing believing? The role of event plausibility and background knowledge in planting false beliefs about the personal past

False memories are more likely to be planted for plausible than for implausible events, but does just knowing about an implausible event make individuals more likely to think that the event happened to them? Two experiments assessed the independent contributions of plausibility and background knowledge to planting false beliefs. In Experiment 1, subjects rated 20 childhood events as to the likelihood of each event having happened to them. The list included the implausible target event “received an enema,” a critical target event of Pezdek, Finger, and Hodge (1997). Two weeks later, subjects were presented with (1) information regarding the high prevalence rate of enemas; (2) background information on how to administer an enema; (3) neither type of information; or (4) both. Immediately or 2 weeks later, they rated the 20 childhood events again. Only plausibility significantly increased occurrence ratings. In Experiment 2, the target event was changed from “barium enema administered in a hospital” to “home enema for constipation”; significant effects of both plausibility and background knowledge resulted. The results suggest that providing background knowledge can increase beliefs about personal events, but that its impact is limited by the extent of the individual’s familiarity with the context of the suggested target event.     

Identity avoidance in the Hebrew lexicon: implications for symbolic accounts of word formation

Hebrew frequently exhibits geminates in the root but strictly constrains their location: Root-initial gemination is rare (e.g., ssm), whereas root-final gemination (e.g., smm) is frequent. Four experiments demonstrate that Hebrew speakers generalize this constraint to novel roots. When speakers are encouraged to form a triliteral root from a biconsonantal input (e.g., sm), they frequently reduplicate the root's final radical (e.g., smm), but not its initial radical (e.g., ssm). Likewise, the rejection of novel root foils with root initial geminates is easier than roots with final geminates. In both cases, speakers' performance is inexplicable by the statistical structure of the Hebrew language. Speakers' ability to freely generalize the constraint on root structure suggests that their linguistic competence appeals to mental variables.     

Peritraumatic dissociation and posttraumatic stress after pregnancy loss: a prospective study

This study examined (1). predictors for peritraumatic dissociation, (2). its relations with acute and chronic symptoms of posttraumatic stress disorder (PTSD), and (3). pathways regarding these relations in response to pregnancy loss. In early pregnancy, about 1370 women volunteers completed questionnaires for neuroticism, control over emotions, dissociative tendencies, absorption, and prior life events. Of these, 126 subsequently experienced pregnancy loss and most of them completed measures 1 month (N = 118) and 4 months (N = 104) later. At 1 month, peritraumatic dissociation, memory of pregnancy loss (degree of fragmentation, sensory impressions, and emotional intensity), thought suppression, and PTSD symptoms were assessed, and at 4 months, PTSD symptoms were re-assessed. Peritraumatic dissociation was predicted by prior low control over emotions, dissociative tendencies, and lower education. It was not predicted by neuroticism, absorption, and prior life events. Peritraumatic dissociation was related to acute PTSD symptoms and LISREL analyses indicated that self-reported memory fragmentation and thought suppression of pregnancy loss mediated this relation. It also predicted chronic PTSD symptoms, and this relation was mediated by acute PTSD symptoms.     

Relations of Masculinity and Femininity with Personality Dimensions of the Five-Factor Model

The aim of this study was to examine therelations of masculinity and femininity with five-factorpersonality dimensions in Croatian adolescents. Sampleconsisted of 464 high school graduates, all of them Caucasian, and approximately 90% Croatian.Results were analyzed by multiple regression procedureusing masculinity, femininity, gender, and theirinteractions as independent variables. All three maineffects were found to be statistically significant,with no significant interactions. Masculinitycontributes positively to extraversion andconscientiousness, and negatively to neuroticism andagreeableness, while femininity shows strong positive relationshipwith agreeableness, and weak positive relationships withthe other four dimensions. Results are discussed interms of four proposed models of the relation between gender role orientation and psychologicalhealth.     

Modelling non‐normal data: The relationship between the skew‐normal factor model and the quadratic factor model

Maximum likelihood estimation of the linear factor model for continuous items assumes normally distributed item scores. We consider deviations from normality by means of a skew‐normally distributed factor model or a quadratic factor model. We show that the item distributions under a skew‐normal factor are equivalent to those under a quadratic model up to third‐order moments. The reverse only holds if the quadratic loadings are equal to each other and within certain bounds. We illustrate that observed data which follow any skew‐normal factor model can be so well approximated with the quadratic factor model that the models are empirically indistinguishable, and that the reverse does not hold in general. The choice between the two models to account for deviations of normality is illustrated by an empirical example from clinical psychology.     

An Item Response Theory Analysis of The Questionnaire of God Representations

The Dutch Questionnaire of God Representations (QGR) was investigated by means of item response theory (IRT) modeling in a clinical (n = 329) and a nonclinical sample (n = 792). Through a graded response model and IRT-based differential functioning techniques, detailed item-level analyses and information about measurement invariance between the clinical and nonclinical sample were obtained. On the basis of the results of the IRT analyses, a shortened version of the QGR (S-QGR) was constructed, consisting of 22 items, which functions in the same way in both the clinical and the nonclinical sample. Results indicated that the QGR consists of strong and reliable scales which are able to differentiate among persons. Psychometric characteristics of the S-QGR were adequate.
