Attention training improves aberrant neural dynamics during working memory processing in veterans with PTSD

Posttraumatic stress disorder (PTSD) is associated with executive functioning deficits, including disruptions in working memory (WM). Recent studies suggest that attention training reduces PTSD symptomatology, but the underlying neural mechanisms are unknown. We used high-density magnetoencephalography (MEG) to evaluate whether attention training modulates brain regions serving WM processing in PTSD. Fourteen veterans with PTSD completed a WM task during a 306-sensor MEG recording before and after 8 sessions of attention training treatment. A matched comparison sample of 12 combat-exposed veterans without PTSD completed the same WM task during a single MEG session. To identify the spatiotemporal dynamics, each group’s data were transformed into the time-frequency domain, and significant oscillatory brain responses were imaged using a beamforming approach. All participants exhibited activity in left hemispheric language areas consistent with a verbal WM task. Additionally, veterans with PTSD and combat-exposed healthy controls each exhibited oscillatory responses in right hemispheric homologue regions (e.g., right Broca’s area); however, these responses were in opposite directions. Group differences in oscillatory activity emerged in the theta band (4–8 Hz) during encoding and in the alpha band (9–12 Hz) during maintenance and were significant in right prefrontal and right supramarginal and inferior parietal regions. Importantly, following attention training, these significant group differences were reduced or eliminated. This study provides initial evidence that attention training improves aberrant neural activity in brain networks serving WM processing.     

Exploring Relationships Between Negative Cognitions and Anxiety Symptoms in Youth With Autism Spectrum Disorder

Although cognitions are central to the conceptualization and treatment of anxiety in typically developing (TD) youth, there is scant research investigating automatic thoughts and their relationship with anxiety in youth with autism spectrum disorder (ASD). We sought to examine the types of automatic thoughts experienced by youth with ASD and co-occurring anxiety as well as the predictive relationship of anxiety to different types of automatic thoughts in 97 children, ages 8-14 years. We also explored the relationship of automatic thoughts and intolerance of uncertainty. Consistent with prior data, there was a strong relationship between anxiety and automatic thoughts pertaining to social and physical threat. Anxiety and IU were independently associated with thoughts pertaining to personal failure which raises the hypothesis that personal failure may serve as a common pathway between anxiety, IU, and depression in ASD youth. These findings highlight the importance of assessing and treating negative cognitions in youth with ASD and anxiety.     

Predicting Response to an Internet-Delivered Parenting Program for Anxiety in Early Childhood

Previous research has identified factors related to outcome in child anxiety treatment and parent training programs for child behavior problems. However, it is unclear what factors predict outcomes in interventions delivered online to parents of young children at risk of anxiety. This study investigated predictors of child anxiety outcomes among 433 families with young children (3–6 years) who participated in a randomized controlled trial of Cool Little Kids Online, an eight-module early intervention program for child anxiety based on cognitive-behavioral therapy (CBT). Potential predictors included baseline demographic factors, child and parent mental health factors, and indicators of program use, including number of online modules completed and frequency of homework practice. Results showed that only access to a printer moderated intervention effectiveness. Printer access predicted lower child anxiety in the Cool Little Kids Online group, but had no effect on outcomes in the wait-list group. In both groups, higher levels of child anxiety symptoms, child-inhibited temperament, and poorer parent mental health at baseline predicted higher levels of child anxiety symptoms at 6-month follow-up. The amount of online program use was not related to improvements in child anxiety symptoms. However, parents who reported practicing the program skills more frequently showed greater reductions in child anxiety, and access to a printer was related to frequency of program skills practice. These findings provide empirical support for the important role of skills practice in online CBT interventions, and suggest that practicing program skills may be more important than completing the online modules.     

Nevin's momentum

With the signing of H.R. 1256, the Family Smoking Prevention and Tobacco Control Act, the United States Food and Drug Administration (FDA) gained regulatory authority over the tobacco industry. A notable clause in this Act permits the FDA to regulate nicotine yields. However, they cannot completely remove this addictive constituent from tobacco products. This restriction has prompted the FDA to seek research on the threshold dose of nicotine that does not support dependence. This idea of threshold dose has led to an interesting reframing of scientific questions. For example, some researchers studying nicotine from this regulatory perspective translated the notion of an addiction threshold to a construct thought to play a role in addiction but which can be more readily operationalized. Examples include reinforcement threshold, discrimination threshold, and reinforcer‐enhancement threshold. In this Perspective Paper, we highlight the importance of behavioral pharmacology and, specifically, the experimental analysis of behavior to help establish a scientific basis for policy decisions regarding nicotine yields. Recent research, including exemplars provided herein, note vast individual differences in the effects of nicotine at a known dose. Unfortunately, the behavioral and biological factors that contribute to such individual variations remain to be understood. We believe that behavior analysts are uniquely well‐positioned to contribute to this understanding.     

Behavioral intervention to reduce physical restraint of adolescents with developmental disabilities

Physical restraint procedures sometimes are approved for implementation in human service settings for children and adults who have developmental disabilities and seriously challenging behaviors. Although use of restraint may be clinically justified to manage behavior disorders and prevent injury to self and others, procedures should be evaluated to decrease, and possibly eliminate, such methods. This study addressed the effects of restraint‐reduction procedures with two adolescents who had developmental disabilities and displayed severe aggression. Clinically significant reductions in the frequency of physical restraint were achieved through a treatment package that included the behavior‐specific criterion for the application of restraint and antecedent control approaches. The implementation of strategic interventions to decrease physical restraint utilization is discussed. Copyright © 2000 John Wiley & Sons, Ltd.     

Effects of Curriculum-Based Monitoring on Classroom Instruction and Math Achievement

In recent years, concerns about the math achievement of U.S. students have been highlighted in the popular press, journal articles, major conference presentations, and official U.S. Department of Education (1998) reports. School personnel have responded to the issue of low math achievement by a) writing or rewriting standards, b) “ratcheting up” current standards, c) building accountability systems that include all students, d) developing programmatic interventions, e) extending the school year, and f) implementing effective instructional management systems. Research on teaching has linked instructional environment and achievement. Thus, this study was designed to determine whether the implementation of an instructional management system served to improve student math achievement and the classroom instructional environment. In addition, the study examined the extent to which adding a curriculum-based monitoring system to an ongoing math curriculum would result in positive changes in the classroom instructional environment and in achievement.     

Achievement orientations from subjective histories of success: Promotion pride versus prevention pride

A new task goal elicits a feeling of pride in individuals with a subjective history of success, and this achievment pride produces anticipatory goal reactions that energize and direct behavior to approach the task goal. By distinguishing between promotion pride and prevention pride, the present paper extends this classic model of achievement motivation. Regulatory focus theory (Higgins, 1997 ) distinguishes between a promotion focus on hopes and accomplishments (gains) and a prevention focus on safety and responsibilities (non‐losses). We propose that a subjective history of success with promotion‐related eagerness (promotion pride) orients individuals toward using eagerness means to approach a new task goal, whereas a subjective history of success with prevention‐related vigilance (prevention pride) orients individuals toward using vigilance means to approach a new task goal. Studies 1–3 tested this proposal by examining the relations between a new measure of participants' subjective histories of promotion success and prevention success (the Regulatory Focus Questionnaire (RFQ)) and their achievement strategies in different tasks. Study 4 examined the relation between participants' RFQ responses and their reported frequency of feeling eager or vigilant in past task engagements. Study 5 used an experimental priming technique to make participants temporarily experience either a subjective history of promotion success or a subjective history of prevention success. For both chronic and situationally induced achievement pride, these studies found that when approaching task goals individuals with promotion pride use eagerness means whereas individuals with prevention pride use vigilance means.

Vengeance: Effects of gender,age, and religious background

Vengeance can be commonly defined as the infliction of harm in return for perceived injury or insult or as simply getting back at another person. Three hundred fifty‐three participants responded to eight hypothetical scenarios that may elicit vengeful behavior in which the offending party was either a romantic partner, a friend, a coworker, or a stranger. Participants also completed a vengeance scale and a measure of biblical literalism. Participants were most vengeful toward coworkers and least vengeful toward romantic partners. Age, religious conservatism, and gender were significant predictors of attitudes toward vengeance. Although men were more likely than women to be accepting of vengeful attitudes as measured by the vengeance scale, only age was a significant predictor of behavior in the vengeance scenarios. The current research provides a basis for a systematic investigation of vengeance within the structure of human relationships and interactions. Aggr.

The anticipated future of counselling psychology in the United States: A Delphi poll

A Delphi poll of the institutional members of the Council of Counselling Psychology Training Programmes in the United States revealed anticipations regarding the future of the speciality in relation to three broad areas of contemporary concern. These included the speciality's anticipated core identity, the future role of science and research training in the speciality, and its probable developments in relation to professional training. In general, a commitment to cultural diversity and life-span development occupied pre-eminent positions in relation to the speciality's anticipated identity. Significant attention to methodological diversity and scientific and professional reform were also noted within the context of continuing challenges to the speciality's identity and its future.     

The role of landmarks in cotton-top tamarin spatial foraging: evidence for geometric and non-geometric features

We report experiments on captive cotton-top tamarins (Saguinus oedipus) designed to explore two components of spatial foraging. First, do tamarins have the capacity to extract geometric information concerning the spatial relationship between a landmark and a piece of food located above or below it? Second, when tamarins use a landmark to find a target location, what non-geometric features of the landmark do they encode? To explore these problems, we created an artificial jungle environment and trained subjects to find food either above or below a target object (i.e., landmark). Once subjects successfully located the food, we transformed various features associated with the landmark, including its color, orientation, and shape; we also manipulated the landmark-food reward distance, the overall shape of the jungle, and the number and position of landmarks. Results showed that the tamarins' success in finding the food reward was not affected by landmark color, orientation, number, or overall shape of the jungle, suggesting that with respect to the particular test conditions, these features are not relevant to the representation of a landmark. Subjects also generalized to novel landmark-food distances, suggesting that they had integrated geometric (i.e., above/below) with non-geometric (i.e., color/shape) features. Performance was negatively affected by changes to the shape of the landmark, indicating that this feature is critical to the representation of a landmark.
