Reduction of implicit cognitive bias with cathodal tDCS to the left prefrontal cortex

Implicit associations can interfere with cognitive operations and behavioral decisions without direct intention. Enhancement of neural activity with anodal transcranial direct current stimulation (tDCS) was proposed to reduce implicit associations by means of improved cognitive control. However, a targeted reduction of distractive implicit associations by inhibitory cathodal tDCS, recently shown in spatial–numerical associations, provides an interesting alternative approach to support goal-directed behavior with transcranial brain stimulation. To test this rationale with a sham-controlled cross-over design, a standardized Implicit Association Test (IAT) was performed by 24 healthy participants parallel to 1 mA cathodal or sham tDCS to the left prefrontal cortex. In this double-classification task, insect versus flower pictures and negative versus positive words are mapped together onto two shared response keys with crossed response assignments in separate blocks. Responses were faster when insect + negative and flower + positive stimuli required the same answer (IAT effect). Most critically, the IAT effect was reduced during cathodal tDCS as compared to sham stimulation. Thus, results are consistent with the proposed stimulation rationale, with previous observations, and complementary to previous studies using different tDCS configurations.     

How socioemotional setting modulates late-stage conflict resolution processes in the lateral prefrontal cortex

The goal-directed control of behaviour critically depends on emotional regulation and constitutes the basis of mental well-being and social interactions. Within a socioemotional setting, it is necessary to prioritize effectively the relevant emotional information over interfering irrelevant emotional information to orchestrate cognitive resources and achieve appropriate behavior. Currently, it is elusive whether and how different socioemotional stimulus dimensions modulate cognitive control and conflict resolution. Theoretical considerations suggest that interference effects are less detrimental when conflicting emotional information is presented within a “positive socioemotional setting” compared with a “negative socioemotional setting.” Using event-related potentials (ERPs) and source localization methods, we examined the basic system neurophysiological mechanisms and functional neuroanatomical structures associated with interactive effects of different interfering facial, socioemotional stimulus dimensions on conflict resolution. We account for interactive effects of different interfering socioemotional stimulus dimensions on conflict resolution, i.e., we show how the socioemotional valence modulates cognitive control (conflict processing). The data show that conflicts are stronger and more difficult to resolve in a negative emotional task-relevant setting than in a positive emotional task-relevant setting, where incongruent information barely induced conflicts. The degree of emotional conflict critically depends on the contextual emotional valence (positive or negative) in which this conflict occurs. The neurophysiological data show that these modulations were only reflected by late-stage conflict resolution processes associated with the middle (MFG) and superior frontal gyrus (SFG). Attentional selection processes and early-stage conflict monitoring do not seem to be modulated by interactive effects of different interfering socioemotional stimulus dimensions on conflict resolution.     

Affordances in Interaction: The Case of Aikido

Our title can be read as trivially true, namely, that perceived affordances shape real-time interaction dynamics. A less trivial reading suggests that affordances themselves interact in a shared dyadic field, such that the number and quality of As and Bs affordances are dynamically coupled with bidirectional causality. In dance, martial arts, or team sports agents strategically comodulate each other's affordances while pursuing their aims. In Aikido, where agents try to break their opponents' balance, this trade-off globally approximates a zero-sum game—the better A's affordances are, the lousier B's affordances get. The agents are subject to ceaseless cross-causation in this shared field. They seek to obstruct their opponents' options while strategically enabling, augmenting, and sculpting their own by employing subtle perceptual manipulation skills, redirecting force, brinkmanship, and switching techniques opportunistically. To overcome static views, we conceptualize affordances as cascading and having fluid onsets; we also identify nested affordances in goal hierarchies and describe a spectrum of affordance functions. Ultimately, we suggest rethinking the ontology of affordances as being sensitive to dynamic engagements, hence defined relative to interpersonal emergence.     

Reappraisal inventiveness: impact of appropriate brain activation during efforts to generate alternative appraisals on the perception of chronic stress in women*

Background and objectives: Previous research indicated that more left-lateralized prefrontal activation during cognitive reappraisal efforts was linked to a greater capacity for generating reappraisals, which is a prerequisite for the effective implementation of cognitive reappraisal in everyday life. The present study examined whether the supposedly appropriate brain activation is relevant in terms of more distal outcomes, i.e., chronic stress perception.

Design and methods: Prefrontal EEG alpha asymmetry was recorded while female participants were generating reappraisals for stressful events and was correlated with their self-reported chronic stress levels in everyday life (n?=?80).

Results: Women showing less left-lateralized brain activity in the ventrolateral prefrontal cortex during cognitive reappraisal efforts reported experiencing more stress in their daily lives. This effect was independent of self-efficacy beliefs in managing negative emotions.

Conclusion: These findings underline the practical relevance of individual differences in appropriate brain activation during emotion regulation efforts and the assumedly related basic capacity for the generation of cognitive reappraisals to the feeling of being stressed. Implications include the selection of interventions for the improvement of coping with stress in women in whom the capability for appropriate brain activation during reappraisal efforts may be impaired, e.g., due to depression or old age.     

The Development,Pilot, and Process Evaluation of a Parent Mental Health Literacy Intervention Through Community Sports Clubs

The mental health literacy of parents may be critical in facilitating positive child and adolescent mental health outcomes. The purpose of this study was to develop, pilot, and evaluate a targeted parent mental health literacy intervention through community sports clubs. Sixty six parents (M_age?=?44.86?±?5.2 years) participated in either a brief mental health literacy intervention workshop delivered through community sporting clubs (n?=?42) or a community-matched control group (n?=?24). Participants’ mental health literacy was assessed at baseline, post-intervention and at 1 month follow-up. A mixed methods process evaluation was conducted with intervention participants to determine the acceptability and feasibility of the intervention. Participants in the experimental group showed greater increases in depression literacy, anxiety literacy, knowledge of help seeking options and confidence to assist an adolescent experiencing a mental health disorder, compared to those in the control group. Post-intervention changes in the experimental group were maintained at 1 month follow-up. A mixed methods process evaluation revealed that parents found the intervention content engaging, relevant to their needs, and practically useful in terms of actively supporting adolescent mental health. Findings provide evidence that a brief, targeted intervention through community sports clubs might be a particularly useful method of improving parental mental health literacy and facilitating positive youth mental health outcomes.     

Advancing Ego Development in Adulthood Through Study of the Enneagram System of Personality

A rapidly growing number of working professionals, academic communities, and businesses have applied the Enneagram personality system of nine types to enhance psychological growth in their personal and professional lives. However, there are no existing studies that measure the effects of the application of Enneagram training programs to promote ego development. This study examined if ego development took place among individuals enrolled in Enneagram training programs in the Narrative Tradition. Two groups of participants (N?=?122) were assessed using the Washington University Sentence Completion Test (WUSCT) at baseline (pretest) before the training began and then again 18 months later (posttest); one of the groups participated in Enneagram Intensive training programs (n?=?73) and the other group participated in introductory Enneagram trainings (n?=?49). Data revealed an advancement in ego development among some of the participants who received at least 40–50 h of training. The findings suggest that Enneagram Intensive trainings may be beneficial for promoting psychological growth and ego development. Clinical applications and future research directions are discussed.     

Acceptability,Feasibility, and Effectiveness of Internet-Based Cognitive-Behavioral Therapy for Obsessive-Compulsive Disorder in New York

Cognitive-behavioral therapy (CBT), consisting of exposure and response prevention (EX/RP), is both efficacious and preferred by patients with obsessive–compulsive disorder (OCD), yet few receive this treatment in practice. This study describes the implementation of an Internet-based CBT program (ICBT) developed in Sweden in individuals seeking OCD treatment in New York. After translating and adapting the Swedish ICBT for OCD, we conducted an open trial with 40 adults with OCD. Using the RE-AIM implementation science framework, we assessed the acceptability, feasibility, and effectiveness of ICBT. The Yale–Brown Obsessive Compulsive Scale (Y-BOCS) was the primary outcome measure. Of 40 enrolled, 28 participants completed the 10-week ICBT. In the intent-to-treat sample (N = 40), Y-BOCS scores decreased significantly over time (F = 28.12, df = 2, 49, p < . 001). Depressive severity (F = 5.87, df = 2, 48, p < . 001), and quality of life (F = 12.34, df = 2, 48, p < . 001) also improved. Sensitivity analyses among treatment completers (N = 28) confirmed the intent-to-treat results, with a large effect size for Y-BOCS change (Cohen’s d = 1.38). ICBT took less time to implement than face-to face EX/RP and participants were very to mostly satisfied with ICBT. On a par with results in Sweden, the adapted ICBT program reduced OCD and depressive symptoms and improved quality of life among individuals with moderate to severe OCD. Given its acceptability and feasibility, ICBT deserves further study as a way to increase access to CBT for OCD in the United States.     

Who Wants to Follow the Leader? Using Personality and Work Value Profiles to Predict Preferences for Charismatic,Ideological, and Pragmatic Styles of Leading

Despite the contributions of charismatic and transformational theories, their universal applicability has recently been called into question. Dovetailing this debate is a growing interest in followers. We contribute to these discussions by examining the impact of follower individual difference profiles on preferences for charismatic, ideological, and pragmatic styles of leading. Drawing on Weber’s (1924) taxonomy of managerial authority in its reconceptualized form as the charismatic-ideological-pragmatic (CIP) model, we conducted a vignette study in which 415 working adults first completed an online survey assessing their personality and work values. Eight weeks later, a second survey asked them to read a fictional scenario about an organization and three speeches depicting each leader’s style. Participants then indicated their leader preference, which we sought to predict using their personality and work values profiles. Results of discriminant function analyses indicated certain linear combinations of personality and work values variables discriminated between participants’ leader preferences.     

Trust,Reliance, and Democracy

Abstract

From the perspective of philosophy and political science it is often pointed out that trust is of central value for democracy. The paper critically examines this claim and argues that we should not overestimate the role of trust in democracy. In order to do that, I argue for a specific understanding of the notion of trust that appropriately accounts for the distinction between trust and mere reliance. In a second step, I argue that we have no reason to put this kind of trust in our elected officials and representatives, but should instead focus on legislative and institutional ways to make sure that they are reliable in particular respects. After contrasting my suggestion with the position of Hardin, I point to two advantages of my account: (1) The avoidance of political analysis through the lens of trust allows us to react more flexibly to unforeseen circumstances and resist populist attempts to emotionalize public debates; (2) at the same time, diffusing the tension between trust and civic vigilance solves a systematic problem in political philosophy. In a concluding section, I briefly discuss the question whether there is an alternative role for trust to play in the field of politics.
