A Multi-Domain Model of Risk Factors for ODD Symptoms in a Community Sample of 4-Year-Olds

Few studies have been designed to assess the pathways by which risk factors are associated with symptoms of psychopathology across multiple domains, including contextual factors, parental depression, parenting, and child characteristics. The present study examines a cross-sectional model of risk factors for symptoms of Oppositional Defiant Disorder (ODD) in a diverse community sample of 796 four-year-old children. In the best-fitting model: (a) SES had indirect effects on contextual factors of stress and conflict, parental depression, and parenting factors including hostility, support, and scaffolding; (b) stress and conflict had both direct effects on ODD symptoms, and indirect effects via parental depression and parenting; (c) parenting had direct effects on ODD symptoms and indirect effects via child effortful control (EC), negative affect (NA) and sensory regulation (SR); (c) NA, EC, and SR had direct effects on symptom frequency, and attachment had indirect effects via EC, and SR. These results highlight the importance of using a multi-domain model to examine risk factors for symptoms of ODD, and also provide information about areas to target in treatment.     

A conceptual and methodological framework for measuring and modulating the attentional blink

The attentional blink (AB) is a transient attention cost that is shown when report accuracy for a second target (T2) is reduced when T2 is presented within approximately 500?ms of a first target (T1). Thus, by definition an AB is only observed when T2 accuracy is reduced at short relative to long T1?CT2 separations, and the magnitude of the AB is reflected in the change in T2 performance across target separations. However, the designs, analyses, and interpretations of several studies of the AB have suggested a lack of clear definitions about what constitutes a demonstration of the AB, what constitutes a modulation of the AB across participant groups or manipulations, and how AB magnitude might best be represented accurately as a single value for a given individual. In this article, we discuss the important conceptual and methodological issues that should be considered when obtaining, analyzing, and interpreting AB data, and we discuss the pros and cons of various approaches while providing suggestions as to how best to validly represent the AB and its modulations.     

Impact of the 1998 football World Cup on suicide rates in France: results from the national death registry

Our objective was to determine whether the Fédération Internationale de Football Association (FIFA) World Cup in 1998 had a short-term impact on the number of suicides in France. Exhaustive individual daily data on suicides from 1979 to 2006 were obtained from the French epidemiological center on the medical causes of death (CepiDC-INSERM; France). These data were analyzed using the seasonal ARIMA model. The overall effect of the World Cup was tested together with potential specific impact on days following the French team games. Between 11th June and 11th July, a significant decline of 95 suicides was observed (-10.3%), this effect being the strongest among men and people aged between 30 and 44. A significant decrease was also observed for the days following French team games (-19.9%). Our results are in favor of an effect of nationwide sport events on suicidal behaviors and are consistent with other studies. Many of the theories explaining the relationship between sports and suicide are related to sense of belongingness and social integration, highlighting the importance of social link reinforcement in suicide prevention.     

A Randomized Controlled Pilot Study of Motivational Interviewing to Change Attitudes about Adherence to Medications for Asthma

The day-to-day management of asthma relies on patient self-care practices; in particular, adherent use of asthma medications is fundamental for asthma management. However, most persons with asthma do not use their medications to clinically acceptable standards. The purpose of this study was to test the efficacy of a brief educational intervention to enhance knowledge and skills relevant to asthma self-care, and the efficacy of motivational interviewing to improve attitudes toward taking medications as prescribed. Twenty-five adults with asthma were randomly assigned to receive a brief educational intervention alone, or education plus motivational interviewing. Over time, all participants improved their knowledge of asthma and skills using a metered dose inhaler. Participants who received education alone showed a decreased level of readiness to adhere with their medications over time, whereas participants who received motivational interviewing were more likely to show a stable or increased level of readiness to adhere over time. Among participants who described themselves as not consistently adhering with their medications at the first evaluation, those who received motivational interviewing endorsed more positive attitudes toward taking medications over time. The results are supportive of the utility of motivational interviewing in enhancing participants' attitudes toward adherent medication use. Future research should test if attitude change is reflected in change in medication use.     

Social–Cognitive Processes in Preschool Boys With and Without Oppositional Defiant Disorder

The social–cognitive characteristics of 88 preschool boys with Oppositional Defiant Disorder (ODD) and 80 nondisruptive boys were assessed 3 times over a 2-year period. Three questions were addressed: (1) Do social–cognitive processes (encoding, attribution, problem solving, and response evaluation) distinguish clinic-referred preschool boys from peers without behavior problems? (2) What is the relation between preschoolers' social–cognitive processes and observed problem behavior? (3) Are the social–cognitive processes of clinic boys with ODD influenced by comorbidity with Attention Deficit Hyperactivity Disorder (ADHD)? Boys were presented hypothetical, peer-oriented social dilemmas to resolve. At all 3 assessments, clinic boys were twice as likely as were comparison group boys to generate aggressive solutions. Relative to comparison boys, clinic boys' encoding of social information was less accurate. The groups did not differ in their attributions or response evaluations. Verbal IQ and language skills were modestly correlated with problem solving and encoding. Within the clinic group, social–cognitive processes were not affected by ADHD comorbidity and they showed little relation to later diagnostic status or severity of behavior problems.     

Self-control and its influence on global/local processing: An investigation of the role of frontal alpha asymmetry and dispositional approach tendencies

People often inhibit or override their dominant response tendencies in order to complete tasks successfully. Exerting such self-control has been shown to influence attentional breadth differently depending on approach-motivated tendencies, as indexed by individuals’ behavioral activation system (BAS) scores. Approach motivation and attentional breadth have previously been associated with frontal alpha asymmetry (i.e., lateralized cortical activity in the frontal regions) where greater left-frontal activation is associated with greater approach motivation and reduced attentional breadth. The process model of self-control posits that exercising self-control leads to a subsequent increase in approach behavior in high BAS individuals, and this could be due to a shift towards left-hemisphere-frontal processing. This was the first study to examine both frontal asymmetry and attentional breadth before and after exercising self-control in low and high BAS individuals. Greater BAS, and greater difficulty exercising self-control, both positively related to more narrowed attentional breadth after completing the manipulation relative to before, but only after exercising self-control. However, breadth of attention and changes in attentional breadth were unrelated to frontal asymmetry, suggesting that the influence of self-control on individuals’ attentional breadth was not due to changes in frontal activation patterns.     

Influence of attended repetition trials on negative priming in younger and older adults

A lengthened response time when a distractor becomes a target, called negative priming, is an undisputed phenomenon in selective attention, yet just what the underlying mechanism responsible for negative priming is has not been resolved. In this study, the proportion of attended repetition trials was manipulated in order to test the predictions of three theories that have been proposed for explaining spatial negative priming: distractor suppression (e.g., Tipper, 1985), episodic memory retrieval (e.g., Neill, Valdes, &; Terry, 1995), and novelty bias (e.g., Milliken, Tipper, Houghton, &; Lupiáñez, 2000). The results supported the proposal that a novelty bias, which is flexible and can be overridden, is the primary mechanism responsible for priming in spatial tasks. Memory retrieval obscured the novelty bias for target processing, was more selective in older adults, and did not affect distractor processing. Novelty bias and distractor suppression may share the same inhibitory attentional mechanism.     

Sexual Harassers: Behaviors, Motives, and Change Over Time

This research was designed to examine the characteristics of sexual harasser behaviors in 118 published arbitration decisions. A qualitative coding process was used to describe behaviors in terms of their severity, type, duration, and frequency. The interrelationships between these characteristics were examined along with the individual’s record of discipline and past aggression. The results indicate that harassers tended to repeat the same types of behavior, and that severity generally increased over time. Although past discipline for sexual harassment appeared to reduce this escalation, it was not very effective in stopping the behaviors. Perpetrators who had engaged in gender harassment were more likely to have a record of aggressive behaviors. Additional comparisons indicate important differences in the behavior of perpetrators as categorized by type of behavior.     

Interrupting infants’ persisting object representations: an object‐based limit?

Making sense of the visual world requires keeping track of objects as the same persisting individuals over time and occlusion. Here we implement a new paradigm using 10-month-old infants to explore the processes and representations that support this ability in two ways. First, we demonstrate that persisting object representations can be maintained over brief interruptions from additional independent events - just as a memory of a traffic scene may be maintained through a brief glance in the rearview mirror. Second, we demonstrate that this ability is nevertheless subject to an object-based limit: if an interrupting event involves enough objects (carefully controlling for overall salience), then it will impair the maintenance of other persisting object representations even though it is an independent event. These experiments demonstrate how object representations can be studied via their 'interruptibility', and the results are consistent with the idea that infants' persisting object representations are constructed and maintained by capacity-limited mid-level 'object-files'.
