Psychopathy and traumatic stress

This study examined the relationship between psychopathy and traumatic stress. First, a sample of 48 male patients in a security hospital was assessed using the Psychopathy Checklist (Hare, 2003) and the Stanford Acute Stress Reactions Questionnaire (SASRQ; Cardena, Classen, Koopman, & Spiegel, 1996). Linear regression analyses suggested that the affect deficit component of psychopathy was the best negative predictor of avoidance, dissociation, and re-experiencing symptoms. The 13 highest-scoring psychopathy participants were then compared to the 13 lowest-scoring participants. Psychopaths differed from controls in terms of number but not type of traumatic events. They obtained significantly lower SASRQ total score, reflecting a lower level of traumatic symptomatology. The results are discussed in connection with the emotional deficit component of psychopathy.     

The Development of Anxiety Disorders: Considering the Contributions of Attachment and Emotion Regulation

Anxiety disorders are among the most common psychiatric disorders in childhood. Nonetheless, theoretical knowledge of the development and maintenance of childhood anxiety disorders is still in its infancy. Recently, research has begun to investigate the influence of emotion regulation on anxiety disorders. Although a relation between anxiety disorders and emotion regulation difficulties has been demonstrated, little attention has been given to the question of why anxious individuals have difficulties regulating their emotions. The present review examines the evidence of the link between emotion regulation and anxiety. It also explores the unique contributions of attachment style and dysfunctional emotion regulation to the development of anxiety disorders.     

Pain, nicotine, and smoking: research findings and mechanistic considerations

Tobacco addiction and chronic pain represent 2 highly prevalent and comorbid conditions that engender substantial burdens upon individuals and systems. Interrelations between pain and smoking have been of clinical and empirical interest for decades, and research in this area has increased dramatically over the past 5 years. We conceptualize the interaction of pain and smoking as a prototypical example of the biopsychosocial model. Accordingly, we extrapolated from behavioral, cognitive, affective, biomedical, and social perspectives to propose causal mechanisms that may contribute to the observed comorbidity between these 2 conditions. The extant literature was 1st dichotomized into investigations of either effects of smoking on pain or effects of pain on smoking. We then integrated these findings to present a reciprocal model of pain and smoking that is hypothesized to interact in the manner of a positive feedback loop, resulting in greater pain and increased smoking. Finally, we proposed directions for future research and discussed clinical implications for smokers with comorbid pain disorders. We observed modest evidence that smoking may be a risk factor in the multifactorial etiology of some chronically painful conditions and that pain may come to serve as a potent motivator of smoking. We also found that whereas animal studies yielded consistent support for direct pain-inhibitory effects of nicotine and tobacco, results from human studies were much less consistent. Future research in the emerging area of pain and smoking has the potential to inform theoretical and clinical applications with respect to tobacco smoking, chronic pain, and their comorbid presentation.

Auditory and visual temporal sensitivity: evidence for a hierarchical structure of modality-specific and modality-independent levels of temporal information processing

The present study investigated modality-specific differences in processing of temporal information in the subsecond range. For this purpose, participants performed auditory and visual versions of a rhythm perception and three different duration discrimination tasks to allow for a direct, systematic comparison across both sensory modalities. Our findings clearly indicate higher temporal sensitivity in the auditory than in the visual domain irrespective of type of timing task. To further evaluate whether there is evidence for a common modality-independent timing mechanism or for multiple modality-specific mechanisms, we used structural equation modeling to test three different theoretical models. Neither a single modality-independent timing mechanism, nor two independent modality-specific timing mechanisms fitted the empirical data. Rather, the data are well described by a hierarchical model with modality-specific visual and auditory temporal processing at a first level and a modality-independent processing system at a second level of the hierarchy.     

Note-taking in the employment interview: effects on recall and judgments

Although note-taking in the employment interview is highly recommended, little research has examined its effects. This study investigated the effects of note-taking styles, review of the notes, and content of the notes on participants' cued recall of information and decisions made from videotaped employment interviews. Note-taking increased recall accuracy but not judgment accuracy. Being able to review notes resulted in increased judgment accuracy for those taking conventional-style notes. The content of the notes also had important implications for conventional note-takers, suggesting some benefits of recording notes using the key-points style. The findings suggest that the act of note-taking may be more important for memory and legal reasons than for improving the decisions made by interviewers.     

Suicide method runs in families: a birth certificate cohort study of adolescent suicide in Taiwan

Suicide method used by adolescents was examined to determine if it was the same as that employed by their suicidal parents. Six hundred eighty adolescents completed suicide between 1997 and 2007, of whom 12 had parents who had previously died by suicide. The suicide method used by these adolescents was compared with that employed by their suicidal parent and that of a matched peer control adolescent with no exposure to parental suicide and living in the same area. In 10 of the 12 suicidal parent-adolescent dyads, the same suicide method was employed by parent and adolescent. Of seven adolescents whose age at parental suicide was 15 years or above, six used the same suicide method as their suicidal parent had. On the contrary, of 12 exposure-nonexposure suicidal adolescent dyads, the same method was used in only four. Adolescents exposed to parental suicide are more likely to use the suicide method employed by their suicidal parents than the method used by adolescent peers with no exposure to parental suicide.
