Naturally occurring language as a source of evidence in suicide prevention

We discuss computational language analysis as it pertains to suicide prevention research, with an emphasis on providing non‐technologists with an understanding of key issues and, equally important, considering its relation to the broader enterprise of suicide prevention. Our emphasis here is on naturally occurring language in social media, motivated by its non‐intrusive ability to yield high‐value information that in the past has been largely unavailable to clinicians.     

Procedure to extract a weekly pattern of performance of human reaction time.

A study of reaction time in six tests (speed of simple identification, simultaneous and sequential letter identification, simultaneous and sequential stimulus word matching, and semantic verification) was carried out on 130 children aged 7 to 12 years. Subjects were tested Monday, Tuesday, Thursday, and Friday, using a cross-sectional design. The answers to each of the tests are binary in nature (Yes/No) measured by the recording of a click one of the two buttons of a microcomputer. Controlled variables were age, failure, sex, and day of test. The greatest percentage of the variance produced by the data was due to the age (typically 25%). The percentage attributable to the "day of test" (typically 5%) is hence masked by the variance due to the other factors. The method proposed herein makes it possible to isolate the percentage of the variance for the variable "day of test" alone and to provide evidence for a circaseptan effect on reaction time. It used a regressive correction on predominant variables. This effect shows performance is best on Thursday and weakest on Monday, the amplitude of the weekly rhythm being related to the task.     

Development of regulation disorders into specific psychopathology

Underlying deficits in self‐regulation and sensory processing are seen in children with regulation disorders (RD) and might lead to emotional and behavioral problems as the child develops. However, little is known about the specific developmental course of RD. This follow‐up study was conducted to investigate the development of a clinical sample of RD children, diagnosed by means of the Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood, Revised (DC:0–3R; ZERO TO THREE, 1994), toward specific psychopathology 4 to 10 years later based on parent‐ and teacher‐reports on the Child Behavior Checklist (T.M. Achenbach & L.A. Rescorla, 2007). Parental reports showed that 39 to 69% of children with RD had internalizing, externalizing, and total problems above borderline cutoffs, as compared to norm group data (16%). In addition, higher rates of affective, anxiety, attention deficit/hyperactivity, oppositional defiant, and conduct problems were reported. Analyses between RD subtypes showed significant differences on future attention problems and rule‐breaking behavior, wherein less favorable results were found for the Hypersensitive subtype Type A (fearful/cautious) in comparison to the sensory stimulation‐seeking/impulsive subtype. The current results indicate persistence of emotional and behavioral problems into middle childhood and adolescence in children with preschool RD diagnoses. More attention should be paid to differentiation of psychopathology in these children since developmental outcomes may differ between RD subtypes.     

Social norms are enforced by friends: The effect of relationship closeness on bystanders’ tendency to confront perpetrators of uncivil,immoral, and discriminatory behaviors

When witnessing an uncivil, immoral, or discriminatory behavior, bystanders have the opportunity to “speak up” and confront the perpetrator about his/her act. We examined whether the closeness of the relationship between the bystander and the perpetrator affects the bystander's reaction. We asked middle schoolers, high schoolers, and university students (N = 1,386) to indicate how they would react if they were to witness each of 26 uncivil, immoral, or discriminatory behaviors. We experimentally manipulated the relationship to the perpetrator, who was described as a friend, an acquaintance, or a stranger. Results showed that the closer the relationship to the perpetrator the greater the bystander's self-reported likelihood of “speaking up.” The findings speak to the role of close relationships in the perpetuation of social norms. They also suggest ways to curb anti-social behaviors in a variety of school and organizational settings.     

Introducing SYPRENE: An International Practice Research Network for Strategic and Systemic Therapists and Researchers

SYPRENE, a new international Systemic Practice Research Network (PRN), has been established to fill the gap in practice-based research on the effectiveness and efficiency of strategic therapies. This article presents the rationale for the creation of SYPRENE and describes data collection methods, and the encoding system implemented within this PRN. More developments are expected in the recruitment of practitioners, the types of data collected, findings, and the implementation of SYPRENE in supervision, trainings, and professional schools.     

The empirical basis of color perception

Rationalizing the perceptual effects of spectral stimuli has been a major challenge in vision science for at least the last 200 years. Here we review evidence that this otherwise puzzling body of phenomenology is generated by an empirical strategy of perception in which the color an observer sees is entirely determined by the probability distribution of the possible sources of the stimulus. The rationale for this strategy in color vision, as in other visual perceptual domains, is the inherent ambiguity of the real-world origins of any spectral stimulus.     

The Political Attitudes and Activities of Mainline Protestant Clergy in the Election of 2000: A Study of Six Denominations

This study examines clergy across six mainline Protestant denominations in terms of their social characteristics, their theological positions, and their political attitudes and behavior. The analysis is based on data collected through random surveys of clergy in each denomination conducted in 2001 using the same instrument. The predominant focus of the article is on the nature and level of political activities exhibited by mainline Protestant clergy in the election year of 2000. The analysis revealed that mainline Protestant clergy are indeed relatively active politically, but that, despite their commonality of belonging to the same broad religious tradition, the nature and level of such political activities varies across the six denominations. Variation in the level of political activity is related to a number of different variables. And, while multivariate analysis reduces the number of significant factors that account for such differences, the remaining significant factors are associated with each of the major theoretical approaches that have been advanced to account for differences in participation levels.     

Cognitive load causes people to react ineffectively to others' norm transgressions

We examined whether cognitive resources are necessary to react effectively to norm transgressions of others. In Study 1, we showed that a polite verbal expression of disapproval was the most effective form of social control because perpetrators were least likely to engage in the same norm transgression again in the future. In Study 2, we manipulated cognitive load and asked participants how they would react when witnessing different uncivil behaviors. Compared to participants in the cognitive load condition, participants in the control condition were more likely to use effective forms of social control and less likely to use ineffective forms of social control. The findings are integrated with recent theorizing about normative pressures and people's reactions to deviance.
