personality, and interests: Evidence for overlapping traits
Assembly and use of new task rules in fronto-parietal cortex
Severe capacity limits, closely associated with fluid intelligence, arise in learning and use of new task rules. We used fMRI to investigate these limits in a series of multirule tasks involving different stimuli, rules, and response keys. Data were analyzed both during presentation of instructions and during later task execution. Between tasks, we manipulated the number of rules specified in task instructions, and within tasks, we manipulated the number of rules operative in each trial block. Replicating previous results, rule failures were strongly predicted by fluid intelligence and increased with the number of operative rules. In fMRI data, analyses of the instruction period showed that the bilateral inferior frontal sulcus, intraparietal sulcus, and presupplementary motor area were phasically active with presentation of each new rule. In a broader range of frontal and parietal regions, baseline activity gradually increased as successive rules were instructed. During task performance, we observed contrasting fronto-parietal patterns of sustained (block-related) and transient (trial-related) activity. Block, but not trial, activity showed effects of task complexity. We suggest that, as a new task is learned, a fronto-parietal representation of relevant rules and facts is assembled for future control of behavior. Capacity limits in learning and executing new rules, and their association with fluid intelligence, may be mediated by this load-sensitive fronto-parietal network
The mediating role of attachment and mentalising in the relationship between childhood maltreatment, self-harm and suicidality
Background
Although the relationship between childhood maltreatment, self-harm and suicidality is well-established, less is known about the mediating mechanisms explaining it. Based on a developmental mentalisation-based theoretical framework, childhood adversity compromises mentalising ability and attachment security, which in turn increase vulnerability to later stressors in adulthood.
Objective
This study aimed to investigate the role of attachment and mentalising as potential mechanisms in the relationship between childhood maltreatment, self-harm and suicidality.
Participants and setting
We recruited 907 adults from clinical and community settings in Greater London.
Methods
The study design was cross-sectional. Participants completed self-report questionnaires on retrospectively rated childhood trauma, and current attachment to the romantic partner, mentalising, self-harm, suicidal ideation and attempt. We used structural equation modelling to examine the data and conceptualized childhood maltreatment as a general factor in a confirmatory bifactor model.
Results
The results showed that childhood maltreatment was both directly associated with self-harm and suicidality and indirectly via the pathways of attachment and mentalising.
Conclusions
These findings indicate that insecure attachment and impaired mentalising partially explain the association between childhood maltreatment, self-harm and suicidality. Clinically, they provide support for the potential of mentalisation-based therapy or other psychosocial interventions that aim to mitigate the risk of self-harm and suicidality among individuals who have experienced childhood maltreatment via increasing understanding of self and other mental states
Attachment and personality disorder as the dance unfolds: A quantitative analysis of a novel paradigm
Current research on personality disorders strives to identify key behavioural and cognitive facets of patient functioning, to unravel the underlying root causes and maintenance mechanisms. This process often involves the application of social paradigms — however, these often only include momentary affective depictions rather than unfolding interactions. This constitutes a limitation in our capacity to probe core symptoms, and leaves potential findings uncovered which could help those who are in close relationships with affected individuals. Here, we deployed a novel task in which subjects interact with four unknown virtual partners in a turn-taking paradigm akin to a dance, and report on their experience with each. The virtual partners embody four combinations of low/high expressivity of positive/negative mood. Higher scores on our symptomatic measures of attachment anxiety, avoidance, and borderline personality disorder (BPD) were all linked to a general negative appraisal of all the interpersonal experiences. Moreover, the negative appraisal of the partner who displayed a high negative/low positive mood was tied with attachment anxiety and BPD symptoms. The extent to which subjects felt responsible for causing partners ’distress was most strongly linked to attachment anxiety. Finally, we provide a fully-fledged exploration of move-by-move action latencies and click distances from partners. This analysis underscored slower movement initiation from anxiously attached individuals throughout all virtual interactions. In summary, we describe a novel paradigm for second-person neuroscience, which allowed both the replication of established results and the capture of new behavioral signatures associated with attachment anxiety, and discuss its limitations
Severe personality disorder in the secure estate: continuity and change
The Response to Offender Personality Disorder Consultation was released in October 2011. For some this is a welcome step in the right direction due to its therapeutic optimism, however for practitioners operating in the secure estate there are significant challenges ahead. This aim of this article is to discuss the increasing convergence of health and criminal justice and their inherent ideological and practical difficulties. It does so with reference to the consultation on offender personality disorder pathways and in particular the implications regarding multi-disciplinary and cross agency approaches to risk, public protection and personality disorder respectfully. It concludes that before embarking on a new wave of determining and responding to those with personality disorder, offender or otherwise, a more in-depth and empirically informed critical reflection is warranted
Effect of Key2Teach on Dutch teachers' relationships with students with externalizing problem behavior:A randomized controlled trial
The teacher-student relationship plays an important role in the academic and behavioral development of primary school children with externalizing problem behavior. However, such problem behavior often threatens the quality of the teacher-student relationship. Teacher-focused coaching intervention Key2Teach aims to improve elements of the relationship between teachers and students with externalizing problem behavior and consists of two phases and four building blocks. This intervention provides primary school teachers with insight into their mental representation of the relationship and opportunities to practice functional interaction skills. In a randomized controlled trial (RCT), effects of Key2Teach on different aspects of the relationship between teachers and students with externalizing problem behavior were examined. In two cohorts, 103 dyads consisting of a teacher and a student with externalizing problem behavior in grades 3-6 were assessed three times during a school year. Fifty-three dyads received the intervention (intervention group), whereas 50 dyads received no intervention (control group). Data were collected on teacher-reported teacher-student closeness and conflict, and on teacher interaction skills in various domains. Results show a significant increase in closeness and a decrease in conflict as a result of Key2Teach, with substantial effect sizes. No effects on teacher interaction skills were found. This study indicates that Key2Teach may help teachers to improve elements of the relationship they have with students with externalizing problem behavior. Implications for practice and future research are discussed
Attitudes, Clinical Practices, and Perceived Advocacy Needs of Professionals With Interests in Personality Disorders
Experts in personality disorders (PDs) generally prefer dimensional diagnostic systems to categorical ones, but less is known about experts’ attitudes toward personality pathology diagnoses in adolescents, and little is known about public health shortfalls and advocacy needs and how these might differ geographically. To fill these gaps, the International Society for the Study of Personality Disorders surveyed 248 professionals with interests in PDs about their attitudes toward different diagnostic systems for adults and adolescents, their PD-related clinical practices, and perceived advocacy needs in their area. Results suggested that dimensional diagnostic systems are preferable to categorical and that skepticism about personality pathology in adolescents may not be warranted. The most pressing advocacy need was the increased availability of PD-related services, but many other needs were identified. Results provide a blueprint for advocacy and suggest ways that professional societies can collaborate with public health bodies to expand the reach of PD expertise and services
Schema therapy for emotional dysregulation: Theoretical implication and clinical applications
The term emotional dysregulation refers to an impaired ability to regulate unwanted
emotional states. Scientific evidence supports the idea that emotional dysregulation
underlies several psychological disorders as, for example: personality disorders, bipolar
disorder type II, interpersonal trauma, anxiety disorders, mood disorders and posttraumatic
stress disorder. Emotional dysregulation may derive from early interpersonal
traumas in childhood. These early traumatic events create a persistent sensitization of
the central nervous system in relation to early life stressing events. For this reason,
some authors suggest a common endophenotypical origin across psychopathologies.
In the last 20 years, cognitive behavioral therapy has increasingly adopted an interactiveontogenetic
view to explain the development of disorders associated to emotional
dysregulation. Unfortunately, standard Cognitive Behavior Therapy (CBT) methods are
not useful in treating emotional dysregulation. A CBT-derived new approach called
Schema Therapy (ST), that integrates theory and techniques from psychodynamic and
emotion focused therapy, holds the promise to fill this gap in cognitive literature. In this
model, psychopathology is viewed as the interaction between the innate temperament
of the child and the early experiences of deprivation or frustration of the subject\u2019s
basic needs. This deprivation may lead to develop early maladaptive schemas (EMS),
and maladaptive Modes. In the present paper we point out that EMSs and Modes
are associated with either dysregulated emotions or with dysregulatory strategies that
produce and maintain problematic emotional responses. Thanks to a special focus on
the therapeutic relationship and emotion focused-experiential techniques, this approach
successfully treats severe emotional dysregulation. In this paper, we make several
comparisons between the main ideas of ST and the science of emotion regulation, and
we present how to conceptualize pathological phenomena in terms of failed regulation
and some of the ST strategies and techniques to foster successful regulation in patients
HEXACO Personality Dimensions Do Not Predict Individual Differences in Adolescent Trust Behavior
Adolescence is an important developmental period for both trust behavior and personality maturation, and individual differences in trust decisions may be related to different personality traits. In the current study, a group of adolescents (n = 483, Mage = 13.5, SDage = 0.4) played two counterbalanced conditions of a multi-round trust game. In one condition, the partner displayed trustworthy behavior (the trustworthy condition), while the partner in the other condition played untrustworthy behavior (the untrustworthy condition). Three types of trust behavior were examined: initial trust behavior, the adaptation of trust behavior (trustworthy condition), and the adaptation of trust behavior (untrustworthy condition). Personality was measured using the Brief HEXACO Inventory. We expected the HEXACO personality dimensions of honesty–humility and agreeableness to be positively associated with initial trust behavior, but conscientiousness to be negatively related to initial trust behavior. The examination of the relationship between these dimensions and the adaptation of trust behavior were conducted on an exploratory basis. The investigation of the relationship between the remaining dimensions (emotionality, extraversion, and openness to experience) and the three types of trust behavior were also carried out on an exploratory basis. For each type of trust behavior, a hierarchical multiple regression analysis was undertaken to examine whether the HEXACO personality dimensions were related to trust behavior. Using frequentist analyses, no evidence was found that supported the HEXACO dimensions as significant predictors of the three types of trust behavior. Moreover, additional Bayesian analyses showed evidence that the hypothesized HEXACO dimensions (honesty–humility, agreeableness, and conscientiousness) did not outperform the non-hypothesized HEXACO dimensions (emotionality, extraversion, and openness to experience). The association between personality traits and trust might be less pronounced during adolescence as personality maturates across an individual’s lifespan. Additionally, due to a heightened sensitivity to the environment, contextual cues may affect adolescent decision-making processes, leaving less room for personality-driven behaviors
