Understanding the Covariation Among Childhood Externalizing Symptoms: Genetic and Environmental Influences on Conduct Disorder,Attention Deficit Hyperactivity Disorder,and Oppositional Defiant Disorder Symptoms

Conduct disorder (CD), attention deficit hyperactivity disorder (ADHD), and oppositional defiant disorder (ODD) are common childhood externalizing disorders that frequently co-occur. However, the causes of their comorbidity are not well understood. To address that question, we analyzed data from > 600 Finnish twin pairs, who completed standardized interviews at age 14. Behavior genetic methods were used to examine how genetic/environmental factors contribute to each disorders symptoms and to their covariation. We found significant genetic effects on each disorder with only modest evidence of shared environmental influences. Our data suggest the comorbidity among CD, ADHD, and ODD is primarily explained by shared genetic influences; however, each disorder was also under unique genetic influence, supporting the distinction of each disorder.     

Aging affects both perceptual and lexical/semantic components of word stem priming: An event-related fMRI study

In this event-related fMRI study, brain activity patterns were compared in extensive groups of young (N=25) and older (N=38) adults, while they were performing a word stem completion priming task. Based on behavioral findings, we tested the hypothesis that aging affects only the lexical/semantic, but not the perceptual component of word stem priming. To this end, we distinguished between priming-related activity reductions in posterior regions involved in visual processing, and regions associated with lexical/semantic retrieval processes, i.e., left lateral temporal and left prefrontal regions. Both groups revealed significant priming-related response time reductions. However, in accordance with earlier findings, a larger priming effect was found in the group of young participants. In line with previous imaging studies, the groups showed common priming-related activity reductions in the anterior cingulate, and the left inferior prefrontal cortex extending into the anterior portion of the left superior temporal gyrus, and at lower thresholds also in the right occipital lobe. However, when directly comparing the groups, greater priming-related reductions were found for the young group in the left anterior superior temporal gyrus and the right posterior occipital lobe. These findings suggest that, converse to current psychological views, aging affects both perceptual and lexical/semantic components of repetition priming.     

Reassessing carbamazepine in the treatment of bipolar disorder: clinical implications of new data

This monograph summarizes the proceedings of a roundtable meeting convened to discuss the role of carbamazepine in the treatment of bipolar disorder, in light of new data and the recent indication of carbamazepine extended-release capsules (CBZ ERC) for use in the treatment of acute manic and mixed episodes. Two lectures were presented, followed by a panel discussion among all 6 participants. A summary of the two pivotal trials of CBZ ERC and their pooled data along with other relevant data is presented first. Next, historical trends of carbamazepine and the agent's use in acute mania, bipolar depression, and maintenance are reviewed, emphasizing clinical implications of efficacy, safety, tolerability, and drug interactions. Finally, the panel discussion provides recommendations for the use of carbamazepine in different phases of the illness, taking into account adverse effects and drug-drug interactions. Panel discussants agree that current data confirm the utility of CBZ ERC as an effective treatment for acute manic and mixed episodes in bipolar disorder. Carbamazepine may also prove to be an option for maintenance treatment. Tolerability of the drug is related to dose and titration, and overall safety limitations regarding carbamazepine usage are comparable to other medications. For some patients, the main challenges to use of carbamazepine may be common drug-drug interactions and increased side effects related to aggressive introduction during treatment of acute manic and mixed episodes. Thus, carbamazepine may be a lower priority option for patients who are taking multiple medications, such as elderly individuals with medical comorbidity, due to the potential for drug interactions. Important benefits of carbamazepine include the low propensity toward weight gain and evidence of good tolerability with long-term treatment. (At present there are no available data from long-term, placebo-controlled studies evaluating the effects of carbamazepine or CBZ ERC on weight.) Thus, carbamazepine may be a good option for patients who are concerned about weight gain or who are intolerant of or respond poorly to other medications. Further efforts are needed to update physicians on the use of carbamazepine relative to other medications in the treatment of bipolar disorder.     

Innovation across cultures: Connecting leadership,identification, and creative behavior in organizations

Innovation is considered essential for today's organizations to survive and thrive. Researchers have also stressed the importance of leadership as a driver of followers' innovative work behavior (FIB). Yet, despite a large amount of research, three areas remain understudied: (a) The relative importance of different forms of leadership for FIB; (b) the mechanisms through which leadership impacts FIB; and (c) the degree to which relationships between leadership and FIB are generalizable across cultures. To address these lacunae, we propose an integrated model connecting four types of positive leadership behaviors, two types of identification (as mediating variables), and FIB. We tested our model in a global data set comprising responses of N = 7,225 participants from 23 countries, grouped into nine cultural clusters. Our results indicate that perceived LMX quality was the strongest relative predictor of FIB. Furthermore, the relationships between both perceived LMX quality and identity leadership with FIB were mediated by social identification. The indirect effect of LMX on FIB via social identification was stable across clusters, whereas the indirect effects of the other forms of leadership on FIB via social identification were stronger in countries high versus low on collectivism. Power distance did not influence the relations.     

Expression and interpretation of emotions in multilingual psychotherapy: A literature review

This review aimed at presenting the findings of 19 original studies that were published in the period from 2000 to 2022 in order to outline the current state of the art in the field of emotion communication (i.e., expressing and interpreting emotions) in multilingual psychotherapy. This analysis involves in particular the studies that investigate multilingual phenomena (e.g., code-switching and language-mixing) that occur during psychotherapeutic sessions when client and therapist can speak more than one language, as well as the articles that research emotion communication in this multilingual setting. With this in mind, the articles selected for this review are divided into two main categories: linguistic phenomena in multilingual psychotherapy and emotion communication in multilingual psychotherapy. Results of the studies in the current analysis reveal that code-switching remains one of the main linguistic phenomena that arises in the area of multilingual psychotherapy. Switching languages in therapy tends to be considered as beneficial for both client and therapist. Besides, findings suggest a connection between speaking L1/LX and one's identity (e.g., feeling different depending on the language). Additionally, studies that investigate emotion communication in multilingual psychotherapy show that an individual's first language (L1) is predominantly viewed as more emotionally charged than their language(s) learned later in life (LX). However, some studies also demonstrate that the relationship between L1 and LX is more fluid and context-dependent than it has traditionally been regarded. Propositions are given for future research in the field of emotion communication in multilingual psychotherapy.     

RELIGION AND EMPIRICISM IN THE WORKS OF PETER BERGER

Abstract. Peter Berger established himself in the sociological profession in large part through his functional interpretations of religion and its ostensible demise in relation to the empirical bent of modern intellectual thought. Yet, in his ef–fort to expand the scope of empiricism such that it might address nontrivial concerns, Berger found himself attempting to understand the "substance" of religiori—that is, the conviction that there exists an "other" which confronts us unconditionally and consequently forms the basis of all issues concerning value and meaning. Berger's writings deserve critical attention in that they disclose both the problems and the promises of utilizing empirical methods for the task of rehabilitating, rather than debunking, humanity's religious propensities.     

Automation and cognition in air traffic control: An empirical investigation

Several investigators have expressed concern that the imminent automation of air traffic control may have negative consequences on cognitive functioning, and ultimately on performance. We investigated these possibilities empirically by comparing normal, conventional air traffic control with an experimental condition designed to resemble an extreme version of automation. Overall, measures of performance were comparable between conditions. Most of the cognitive measures (attentional demands, visual search, recall of flights, recall of flight data) were not impaired by the automation analogue. Instead, two prospective measures (prospective memory, planning) showed improved performance. The prospective memory advantage is particularly surprising given that the automation-analogue group was unable to manipulate external memory aids. Possible reasons for the prospective memory advantage include a reduced workload, which allows the controller to get the necessary information in other ways, and a change in the nature of the task resulting from the “automation” of the strip management module.     

The 3DPT dimensions S,E, and N: A critical evaluation of Eysenck's Psychoticism model

In this article a critical evaluation is given of Eysenck's Psychoticism model. It is argued that in this model two sub-models can be distinguished, which, contrary to Eysenck's presentation, cannot be regarded as true extensions of each other. With respect to one of these models, the ?genotypic’? P-model, the theory is criticized in that both schizophrenia and affective psychosis are determined by a common genetic predisposition which can phenotypically manifest itself in variations of P. Instead of this theory, the likelihood is put forward that a high EPQ-P score, albeit in combination with a high N and a low E score (and notwithstanding the fact that criminals or psychopaths can also obtain high P scores), is (only) related to the schizoid state, and hence, that P seems to be relevant either as a predisposing factor contributing to the development of schizophrenic psychosis, or as a factor on which biological relatives of schizophrenics obtain higher scores on average than normals do. In this respect, Eysenck's theory that the non-schizoid form of psychopathy can also be found among first-degree relatives of schizophrenics, and hence, that psychopathy and schizoidia are genetically related, is also criticized. Furthermore, it is argued that Eysenck's EPQ-P scale is not optimal for measuring those traits of the schizoid personality which are independent of N and/or E. Both arguments regarding the contents of this scale and arguments with respect to the demonstrated lack of invariance of the EPQ-P factor are adduced to support this statement. Thus, an alternative scale for measuring ?P’? (labelled S or Insensitivity) was designed by us. The S-scale is based on literature concerning the schizoid state and reflects the results of a series of principal components analyses of (potential) S items, together with N and E items, put into execution with the intention of investigating the invariance of the S factor (and of E and N) with respect to six sample and other parameters. These investigations were carried out on a large, representative sample of the Dutch population. Additional investigations were carried out concerning the reliability and validity of the three newly formed scales. The results of these investigations turned out to be very satisfactory or, in some respects, at least promising. Finally, in this article, comments are made on the nature of the S factor, comparing this dimension with both Eysenck's P factor and the dimensions Agreeableness and Conscientiousness, as proposed, for instance, in McCrae and Costa's version of Nor-man's 5-factor model. As against P, the S or Insensitivity factor seems to be only (negatively) related to Agreeableness and not to Conscientiousness. It is also argued that this finding seems to be in accord with the supposed schizoid nature of S and the criticisms levelled at Eysenck's EPQ-P scale.
