基于三元精神病态模型的精神病态认知-情感加工框架

精神病态作为暴力犯罪、累犯和青少年犯罪的重要预测变量, 在临床心理学和司法领域受到了广泛重视。三元精神病态模型通过大胆、卑劣和去抑制三个维度对精神病态进行了操作化定义, 反映了精神病态在神经生物学维度上存在的认知情感加工缺陷。其中, 低威胁敏感性是精神病态大胆的主要病因学基础; 而执行功能受损, 尤其是注意调节缺陷则导致了精神病态的去抑制倾向; 而与情绪识别存在联系的共情缺陷可能是卑劣的深层原因。未来研究中仍需关注精神病态的概念化问题, 以及不同精神病态特质之间是否存在共同的潜在病因学基础, 探索精神病态特质在生命早期阶段的体现从而进行及时有效的干预。     

社会动机理论视角下自闭症谱系障碍者的社交缺陷

社交缺陷是自闭症谱系障碍的核心症状。以往研究更多从社会认知的角度指出该症状是心理理论损伤所致, 但自闭症谱系障碍个体在获得心理理论之前已表现出社会动机不足的特质, 且部分能通过心理理论测试的个体依旧表现出社会动机不足的特点。社会动机理论指出社会动机是促进人类进化、激发和维持个体社会性活动的重要内部动力, 自闭症谱系障碍者的社交缺陷是由于社会动机不足所致。该理论从行为表现、神经科学和生物学三个方面对自闭症谱系障碍者的社交缺陷进行解释。未来应进一步完善自闭症谱系障碍个体社会动机的神经机制研究, 明确社会动机理论在自闭症谱系障碍群体中的适用范围, 探究社会动机理论在评估诊断和临床康复中的应用价值。     

The effect of perceived control on self-reported cardiovascular disease incidence across adulthood and old age

Objective: To examine whether rates of change in perceived control are predictive of cardiovascular disease (CVD) incidence across adulthood and old age.

Design: We used the PATH Through Life Project (n = 7103, M = 40, SD = 16; 52% women), a longitudinal panel survey that encompasses three cohorts at Time 1, ages 20–24, 40–44 and 60–64, who have been assessed three times at four-year intervals.

Method: We examined whether rates of change in perceived control were associated with CVD incidence over 8 years of time, over and above that of baseline levels of perceived control and known risk factors for CVD.

Main Outcome Measures: Self-reported CVD incidence.

Results: Increases in perceived control over time were associated with decreased likelihood of 8-year incidence of CVD and these effects were independent of socio-demographics, covariates and baseline levels of perceived control. The effects were consistent across young adulthood, midlife and old age and for men and women.

Conclusions: Findings demonstrate the importance of changes in perceived control as a predictor of CVD incidence across adulthood and old age. We suggest future research using mediation analysis to test reverse causality and mechanisms underlying the effects of perceived control on CVD incidence.     

青少年早期冲动性的发展轨迹:界定亚群组及其影响因素

以发展的整体互动论和生态系统理论为基础,考察青少年早期冲动性的发展轨迹及其影响因素。采用Barratt冲动性量表、家庭环境量表、青少年感知校园氛围问卷对天津市某中学210名初中生进行了为期1年的3次追踪调查,使用潜变量增长模型、潜类别增长模型、多元Logistic回归进行数据分析。结果发现:(1)青少年早期冲动性的发展呈线性增长趋势,并可分为三个亚群组:恒低组(16.67%)、恒高组(41.43%)和居中升高组(41.91%);(2)家庭环境亲密度和教师支持对亚群组有显著预测作用。本研究揭示了在青少年早期冲动性的动态变化性、个体差异性及其相关影响因素。     

Generalized instruction following with pictorial prompts

The benefits of permanent pictorial prompts in enhancing maintenance and generalization are likely dependent on their degree of stimulus control and the extent to which their use is generalized. Although several studies on the use of pictorial prompts have demonstrated their efficacy (e.g., Pierce & Schreibman, 1994; Wacker & Berg, 1983; Wacker, Berg, Berrie, & Swatta, 1985), there is still some question regarding what ultimately controlled responding. The present study allowed an explicit examination of stimulus control by pictorial prompts. Three 4-year-old children with developmental disabilities were taught to complete 4 instructional sets (5 steps each) using pictorial prompts such that the prompts would control responding. All 3 participants showed generalization to the final set after training with 3 sets. These results suggest that training a single task sequence may not be sufficient for acquisition of generalized pictorial instruction following. However, establishing stimulus control by the pictorial prompts rather than teaching behavioral chains may facilitate acquisition of a generalized repertoire.     

Semantic interference during object naming in agrammatic and logopenic primary progressive aphasia (PPA)

This study examined the time course of object naming in 21 individuals with primary progressive aphasia (PPA) (8 agrammatic (PPA-G); 13 logopenic (PPA-L)) and healthy age-matched speakers (n = 17) using a semantic interference paradigm with related and unrelated interfering stimuli presented at stimulus onset asynchronies (SOAs) of −1000, −500, −100 and 0 ms. Results showed semantic interference (SI) (i.e. significantly slower RTs in related compared to unrelated conditions) for all groups at −500, −100 and 0 ms, indicating timely spreading activation to semantic competitors. However, both PPA groups showed a greater magnitude of SI than normal across SOAs. The PPA-L group and six PPA-G participants also evinced SI at −1000 ms, suggesting an abnormal time course of semantic interference resolution, and concomitant left hemisphere cortical atrophy in brain regions associated with semantic processing. These subtle semantic mapping impairments in non-semantic variants of PPA may contribute to the anomia of these patients.     

Evolution of Research on Interventions for Individuals with Autism Spectrum Disorder: Implications for Behavior Analysts

The extraordinary success of behavior-analytic interventions for individuals with autism spectrum disorder (ASD) has fueled the rapid growth of behavior analysis as a profession. One reason for this success is that for many years behavior analysts were virtually alone in conducting programmatic ASD intervention research. However, that era has ended. Many investigators from other disciplines are now carrying out large-scale intervention studies and beginning to report successes of their own. The increasing number and range of studies has the potential to improve services for individuals with ASD, and it challenges behavior analysts to intensify their research efforts.     

Agnosticism gone awry: Why developmental robotics must commit to an understanding of embodiment and shared intentionality

We argue that developmental robotics, in its integration of developmental psychology and robotics, has the potential to encounter unexpected and unexamined conceptual difficulties. In particular, the various uses of embodiment and shared intentionality single out certain robots and behaviors as more or less relevant for the modeling of social cognition. As these terms have relatively orthogonal histories, there is no account for how their use will interact to shape methodology. We provide a brief discussion of how they may do so. Moreover, theorists often avoid explicit endorsement of some use or another. Although this agnosticism is understandable, we use the model of Dominey and Warneken (2011) as an illustrative example of why it is potentially dangerous. While Dominey and Warneken have succeeded in encouraging theorists to adopt clearer formulations of shared intentionality, their model suffers from important difficulties in interpretation, which, we argue, are a consequence of their uses of embodiment and shared intentionality respectively.     

Adaptation of the Children's Friendship Training Program for Children with Fetal Alcohol Spectrum Disorders

ABSTRACT

Previous research attests to the marked impairments in social functioning exhibited by children with Fetal Alcohol Spectrum Disorders (FASD), suggesting that such children are in need of social skills intervention. Recently, an existing evidence-based manualized behavioral treatment for improving children's friendships was implemented and demonstrated to be effective with children aged 6–12, diagnosed with FASD. In the present report, we describe methods for adapting this behavioral intervention in line with the specific cognitive and behavioral deficits seen in children with FASD and other developmental disabilities to enhance treatment efficacy.
