Stopping and restarting an unfolding action at various times.

The ability to inhibit an unfolding action is usually investigated using a stop signal (or gostop) task. The data from the stop-signal task are often described using a horse-race model whose key assumption is that each process (i.e., go, stop) exhibits stochastic independence. Using three variations of a coincident-timing task (i.e., go, gostop, and gostopgo) we extend previous considerations of stochastic independence by analysing the go latencies for prior effects of stopping. On random trials in the gostopgo task the signal sweep was paused for various times at various distances before the target. Significant increases in latency errors were reported on those trials on which the signal was paused (p <.005). Further analyses of the pause trials revealed significant effects for both the stopping interval (p <.001) and the pause interval (p <.05). Tukey post hoc analyses demonstrated increased latency errors as a linear function of the stopping interval, as expected, and decreased latency errors as a nonlinear function of the pause interval. These latter results indicate that the latencies of the go process, as reflected in the latency errors, may not exhibit stochastic independence under certain conditions. Various control mechanisms were considered in an attempt to explain these data.     

Cultural evidence for interpretation bias as a feature of social anxiety in Chinese adolescents

Background and Objectives: Interpretation bias (IB), defined as the tendency to interpret ambiguous social situations in a threatening manner, has increasingly been studied in children and adolescents. Compared to Western samples, the relation between IB and social anxiety in Chinese youth has received little attention. The present study was to mainly examine the relationship between IB and social anxiety among Chinese adolescents.

Design: Cross-sectional design was utilized.

Methods: IB, measured by the Adolescents’ Interpretation Bias Questionnaire (AIBQ), and social anxiety were surveyed among a group of high socially anxious Chinese adolescents (n?=?25) and a control group (n?=?29). Participants were asked to rate the likelihood of interpretations coming to mind in social/non-social situations and to choose the most believable interpretation.

Results: The high social anxiety group had more negative interpretations and beliefs in social situations, and the interpretation bias was particular to social anxiety versus depression. Additionally, the cognitive content-specificity hypothesis was supported; the high anxious group showed interpretation bias in social situations, but didn’t have more negative interpretations of non-social situations, after controlling for depression.

Conclusions: The present study yielded comparable findings as found in Western samples regarding the relation between IB and social anxiety.     

走向世界哲学的曙光——论卡尔·雅斯贝尔斯的未来世界哲学规划

“世界哲学”(Weltphilosophie)是卡尔·雅斯贝尔斯(Karl Jaspers,1883~1969)哲学中最重要的理念之一。早在1951年,他就用一种富于想象力的语言表达了一种敏锐的时代过渡意识:“我们是从欧洲哲学的晚霞出发,穿过我们这个时代的薄暮而走向世界哲学的曙光。”[1]根据这一时代过渡     

Illness representations,pain and physical function in patients with rheumatic disorders: between- and within-person associations

Objectives: Rehabilitation for patients with rheumatic diseases improves both illness representations (IR) and clinical outcomes such as pain and physical functioning (PF). However, it is unclear whether IR may affect and, in turn, are affected by pain and PF. In this study, we examined both between-person associations and within-person associations between IR and pain/PF over time on three measurement occasions. Furthermore, cross-lagged relationships were examined.

Design and main outcome measures: This secondary analysis is based on data from N?=?186 patients with rheumatic diseases. Data on pain, PF and IR were assessed using self-report questionnaires at the beginning, the end and three months after a 3-week inpatient rehabilitation.

Methods: To separate between- and within-person level, data were analysed using random-intercept cross-lagged panel models.

Results: On both the between-person level (r?=?|0.21|???|0.44|) and the within-person level (r?=?|0.15|???|0.46|), pain and PF were related to cognitive and emotional IR. In addition, we found within-person bidirectional cross-lagged effects between emotional IR and PF.

Conclusion: IR show complex relationships with pain and PF. Improving PF might improve subsequent illness-related emotional distress and vice versa.     

The utility of the Psychopathy Checklist-Revised (PCL-R) facet and item scores in predicting violent recidivism

There is relatively limited research on psychopathy in non-Caucasian ethnic groups and even less on the utility of the Psychopathy Checklist-Revised (PCL-R) that focuses on PCL-R facet and item scores in predicting violent recidivism. In this study, we assessed the utility of the PCL-R in prospectively predicting violent versus nonviolent recidivism during an 11-year follow-up window. A high-risk sample of 451 incarcerated Korean male offenders was assessed on the PCL-R at baseline. A total of 445 were reconvicted after release (353 violent and 92 nonviolent recidivists). Psychopathy facet scores were higher in violent compared to nonviolent recidivists. Facet 2 (affective) showed the strongest effect size (Cohen's d = 0.53; Percentage change in odds = 22.6%) in predicting violent recidivism. Analyses of the four items constituting the affective facet indicated that callous/lack of empathy (Percentage change in odds = 134.4%) and failure to accept responsibility (Percentage change in odds = 94.5%) were the strongest predictors of violent recidivism. Findings are to our knowledge the first to document the utility of the PCL-R in distinguishing violent from nonviolent recidivism and highlight the role of affective impairment (particularly lack of empathy) in violent recidivism.
