Brain structure abnormalities in young women who presented conduct disorder in childhood/adolescence
Meenal Budhiraja Ivanka Savic Philip Lindner Jussi Jokinen Jari Tiihonen Sheilagh Hodgins 《Cognitive, affective & behavioral neuroscience》2017,17(4):869-885
The phenotype and genotype of antisocial behavior among females are different from those among males. Previous studies have documented structural brain alterations in males with antisocial behavior, yet little is known about the neural correlates of female antisocial behavior. The present study examined young women who had presented conduct disorder (CDW) prior to age 15 to determine whether brain abnormalities are present in adulthood and whether the observed abnormalities are associated with comorbid disorders or maltreatment that typically characterize this population. Using magnetic resonance imaging and voxel-based morphometry, we compared gray matter volumes (GMV) of 31 women who presented CD by midadolescence and 25 healthy women (HW), age, on average, 23 years. Participants completed structured, validated interviews to diagnose mental disorders, and validated questionnaires to document physical and sexual abuse. Relative to HW, CDW presented increased GMV in the left superior temporal gyrus that was associated with past alcohol and drug dependence, current use of alcohol and drugs, and current anxiety and depression symptoms and maltreatment. Additionally, CDW displayed reduced GMV in lingual gyrus, hippocampus, and anterior cingulate cortex that was associated with past comorbid disorders, current alcohol and drugs use, current anxiety and depression symptoms, and maltreatment. The CDW also presented reduced total GMV that was associated with past comorbid disorders and current anxiety/depression symptoms. Alterations of brain structure were observed among young adult females with prior CD, relative to HW, all of which were associated with internalizing and externalizing disorders and maltreatment that typically accompany CD. 相似文献

Decades of research and more than 20 randomized controlled trials show that Virtual Reality exposure therapy (VRET) is effective in reducing fear and anxiety. Unfortunately, few providers or patients have had access to the costly and technical equipment previously required. Recent technological advances in the form of consumer Virtual Reality (VR) systems (e.g. Oculus Rift and Samsung Gear), however, now make widespread use of VRET in clinical settings and as self-help applications possible. In this literature review, we detail the current state of VR technology and discuss important therapeutic considerations in designing self-help and clinician-led VRETs, such as platform choice, exposure progression design, inhibitory learning strategies, stimuli tailoring, gamification, virtual social learning and more. We illustrate how these therapeutic components can be incorporated and utilized in VRET applications, taking full advantage of the unique capabilities of virtual environments, and showcase some of these features by describing the development of a consumer-ready, gamified self-help VRET application for low-cost commercially available VR hardware. We also raise and discuss challenges in the planning, development, evaluation, and dissemination of VRET applications, including the need for more high-quality research. We conclude by discussing how new technology (e.g. eye-tracking) can be incorporated into future VRETs and how widespread use of VRET self-help applications will enable collection of naturalistic “Big Data” that promises to inform learning theory and behavioral therapy in general. 相似文献

We present a discussion of some of the lessons the investigators learned during the development and implementation phases of the Parents Matter! Program (PMP). Lessons were learned that are relevant to various groups involved in large scale, multi-site, community-based intervention studies: investigators, community leaders, community members, project staff, and participants. Specific lessons learned include: (1) forge collaboration early: (2) maintain communication; (3) clearly delineate policies and procedures; and (4) develop proactive strategies. We also include a list of important questions to consider when contemplating similar projects. 相似文献

Two-choice response times are a common type of data, and much research has been devoted to the development of process models for such data. However, the practical application of these models is notoriously complicated, and flexible methods are largely nonexistent. We combine a popular model for choice response times-the Wiener diffusion process-with techniques from psychometrics in order to construct a hierarchical diffusion model. Chief among these techniques is the application of random effects, with which we allow for unexplained variability among participants, items, or other experimental units. These techniques lead to a modeling framework that is highly flexible and easy to work with. Among the many novel models this statistical framework provides are a multilevel diffusion model, regression diffusion models, and a large family of explanatory diffusion models. We provide examples and the necessary computer code. 相似文献

Background. Students’ perceptions of classroom goals influence their adoption of personal goals. To assess different forms of classroom goals, recent studies have favoured an overall measure of performance classroom goals, compared to a two‐dimensional assessment of performance‐approach and performance‐avoidance classroom goals (PAVCG). Aims. This paper considered the relationship between students’ perceptions of classroom goals and their endorsement of personal achievement goals. We proposed that three (instead of only two) classroom goals need to be distinguished. We aimed to provide evidence for this hypothesis by confirmatory factor analysis (CFA) and also by divergent associations between the respective classroom goal and students’ personal goal endorsement. Sample. A total of 871 (474 female) 10th grade students from several German high schools participated in this study. Method. Students responded to items assessing their perception of mastery, performance‐approach, and performance‐avoidance goals in the classroom. Additionally, the students reported how much they personally pursue mastery, performance‐approach, and performance‐avoidance goals. All items referred to German as a specific school subject. Results. A CFA yielded empirical support for the proposed distinction of three (instead of only two) different kinds of classroom goals. Moreover, in hierarchical linear modelling (HLM) analyses all three classroom goals showed unique associations with students’ personal goal adoption. Conclusions. The findings emphasized the need to distinguish performance‐approach and PAVCG. Furthermore, our results suggest that multiple classroom goals have interactive effects on students’ personal achievement strivings. 相似文献

Self-regulation of behavior frequently requires that people disengage from goals that are too difficult to attain. The current
studies investigate whether self-focused rumination hinders the execution of this crucial self-regulatory competence. In study
one, participants attempted to solve anagrams, some of which were unsolvable, and their predisposition to engage in self-focused
rumination was assessed. The tendency to ruminate was associated with getting stuck in the attempt to solve unsolvable anagrams.
In study two, ruminative thoughts were manipulated by asking participants to focus on their self, personality, and goals in
life, a task frequently employed to induce rumination. Compared to participants undergoing a distraction induction, ruminating
participants were more likely to get stuck trying to solve unsolvable anagrams. These results suggest that self-focused rumination
hinders disengagement from unattainable goals. 相似文献

Previous research has shown that the formation of units or chunks contributes to sequence learning in serial reaction time
(SRT) tasks (Koch & Hoffmann, Psychological Research 63:22–35, 2000). However, some of these results were assumed to be unrelated to sequence learning and to reflect preexistent response tendencies
(Jiménez, Psychological Research 72:387–396, 2008). In the Experiment of this study, we aimed to evaluate this issue. One group of participants responded to a strongly structured
sequence of digits by pressing one out of six response keys depending on digit identity. In a second experimental group, a
weakly structured sequence was presented, which contained comparable transitions among the single items, but did not have
series of ascending and descending triplets of successive digits. The results indicated that serial learning in general as
well as response tendencies to certain fragments of the sequence were modulated by the manipulation of the strength of relational
patterns. The data are consistent with the notion that relational patterns contribute to the formation of chunks as suggested
in the original study. 相似文献

Chronic fatigue syndrome (CFS) is a poorly understood illness that is characterized by profound and prolonged exhaustion and
has no clear pathological marker. This study investigated the role of illness severity and secondary beliefs in depression
among a CFS cohort, using the A–B–C framework of Rational Emotive Behavioral Therapy. Empirical research has consistently
found that CFS patients tend to hold more negative cognitions about their illness, which could be associated with greater
severity and emotional deficits. Specifically, secondary beliefs were explored as a mediating factor; as evidence suggests
that secondary beliefs can result in dysfunctional emotions and/or behaviors, such as depression. Furthermore, it is estimated
that up to 80% of CFS patients concurrently have depression. There were 156 participants with CFS who completed a questionnaire
pack, which included the revised version of the Illness Perception Questionnaire, the Secondary Beliefs Scale (SBS), and the
Cardiac Depression Scale. Hierarchical regression analysis revealed that secondary beliefs mediated the relationship between
illness severity and depression. Specifically, the approval and comfort subscales of the SBS were significantly associated
with depression. The current findings indicated that secondary beliefs could be an important focus in treatment of depression
in chronic illness. As the mediating role of secondary beliefs is a new research finding, it is advised that further exploratory
research is required. 相似文献
