Development of a parent training program for children with pervasive developmental disorders

Parent delivered interventions based on applied behavior analysis (ABA) for children with Pervasive Developmental Disorders (PDDs) have been evaluated using primarily single‐subject design methodology or small case series. While the results of these evaluations are encouraging, an important next step is to standardize the interventions to allow for replication across sites, in studies with large samples and measures of long‐term, clinically meaningful outcomes such as improvements in children's functioning and their relationships with parents. Accordingly, the Research Units on Pediatric Psychopharmacology and Psychosocial Interventions (RUPP Autism Network) assembled a detailed manual for a structured behavioral parent training (PT) program, developed treatment fidelity and training procedures, and conducted a pilot, feasibility study. The PT program is part of a large scale, multisite study intended to determine the efficacy of combined pharmacological treatment and behavioral intervention to improve behavior and adaptive functioning in children with PDD. This paper discusses the rationale for this project. A companion paper provides the results of our feasibility study on the PT program. Copyright © 2007 John Wiley & Sons, Ltd.     

Stereotype threat and test performance: A primer for school psychologists

Ethical guidelines require school psychologists to ensure that their assessment practices are nondiscriminatory, but typical discussions on this topic neglect the possible discriminatory effects of cultural stereotypes on assessment results. Recent research on stereotype threat shows that students' knowledge of stereotype-based negative expectations about their test performance can depress their actual test performance. This paper discusses the range of conditions that promote stereotype threat and identifies important moderators and mediators of the phenomenon. Several practical suggestions are offered for school psychologists to consider when interviewing students, interpreting assessment results, and developing programs to increase schoolwide achievement.     

Improving access to psychological therapy: Initial evaluation of two UK demonstration sites

Recently the UK Government announced an unprecedented, large-scale initiative for Improving Access to Psychological Therapies (IAPT) for depression and anxiety disorders. Prior to this development, the Department of Health established two pilot projects that aimed to collect valuable information to inform the national roll-out. Doncaster and Newham received additional funds to rapidly increase the availability of CBT-related interventions and to deploy them in new clinical services, operating on stepped-care principles, when appropriate. This article reports an evaluation of the new services (termed ‘demonstration sites’) during their first thirteen months of operation. A session-by-session outcome monitoring system achieved unusually high levels of pre to post-treatment data completeness. Large numbers of patients were treated, with low-intensity interventions (such as guided self-help) being particularly helpful for achieving high throughput. Clinical outcomes were broadly in line with expectation. 55-56% of patients who had attended at least twice (including the assessment interview) were classified as recovered when they left the services and 5% had improved their employment status. Treatment gains were largely maintained at 10 month follow-up. Opening the services to self-referral appeared to facilitate access for some groups that tend to be underrepresented in general practice referrals. Outcomes were comparable for the different ethnic groups who access the services. Issues for the further development of IAPT are discussed.     

Children’s Externalizing and Internalizing Symptoms over Time: The Role of Individual Differences in Patterns of RSA Responding

We examined associations between basal respiratory sinus arrhythmia (RSA) in conjunction with RSA regulation with the hypothesis that their interaction would explain unique variability in children’s prospective adjustment 2 years later. Participants were 176 children (98 girls; 78 boys) in middle childhood. RSA regulation was assessed through social and problem-solving challenges. Parents reported on children’s internalizing and externalizing symptoms. Interactions between RSA baseline and regulation to the social stressor predicted children’s later internalizing symptoms. Interactions between RSA baseline and responding to the problem-solving stressor predicted children’s externalizing symptoms. The highest levels of internalizing symptoms were predicted for children with both lower basal RSA and higher RSA suppression. The highest levels of externalizing symptoms were predicted for children who demonstrated lower basal RSA in conjunction with RSA augmentation. Findings highlight the importance of the contemporaneous consideration of basal RSA and RSA regulation in the prediction of developmental psychopathology symptomology.     

Cognitive models of choice: comparing decision field theory to the proportional difference model

People often face preferential decisions under risk. To further our understanding of the cognitive processes underlying these preferential choices, two prominent cognitive models, decision field theory (DFT; Busemeyer & Townsend, 1993 ) and the proportional difference model (PD; González-Vallejo, 2002 ), were rigorously tested against each other. In two consecutive experiments, the participants repeatedly had to choose between monetary gambles. The first experiment provided the reference to estimate the models' free parameters. From these estimations, new gamble pairs were generated for the second experiment such that the two models made maximally divergent predictions. In the first experiment, both models explained the data equally well. However, in the second generalization experiment, the participants' choices were much closer to the predictions of DFT. The results indicate that the stochastic process assumed by DFT, in which evidence in favor of or against each option accumulates over time, described people's choice behavior better than the trade-offs between proportional differences assumed by PD.     

Attention for emotional faces under restricted awareness revisited: do emotional faces automatically attract attention?

Theoretical models of attention for affective information have assigned a special status to the cognitive processing of emotional facial expressions. One specific claim in this regard is that emotional faces automatically attract visual attention. In three experiments, the authors investigated attentional cueing by angry, happy, and neutral facial expressions that were presented under conditions of limited awareness. In these experiments, facial expressions were presented in a masked (14 ms or 34 ms, masked by a neutral face) and unmasked fashion (34 ms or 100 ms). Compared with trials containing neutral cues, delayed responding was found on trials with emotional cues in the unmasked, 100-ms condition, suggesting stronger allocation of cognitive resources to emotional faces. However, in both masked and unmasked conditions, the hypothesized cueing of visual attention to the location of emotional facial expression was not found. In contrary, attentional cueing by emotional faces was less strong compared with neutral faces in the unmasked, 100-ms condition. These data suggest that briefly presented emotional faces influence cognitive processing but do not automatically capture visual attention.     

When intended remembering leads to unintended forgetting

As a means of clarifying the memory dynamics that underlie retrieval-induced forgetting, we explored how instructing participants either to remember or to forget a previously presented list of items influences the susceptibility of those items to inhibition. According to the inhibitory account of retrieval-induced forgetting, it is the items that interfere most with retrieval practice that should be the most susceptible to the effects of inhibition. Consistent with this prediction, items from lists that participants were told to remember suffered from significantly more retrieval-induced forgetting than did items from lists that participants were told to forget.     

How Not to Refute Quine: Evaluating Kim's Alternatives to Naturalized Epistemology

This paper offers an interpretation of Quine's naturalized epistemology through the lens of Jaegwon Kim's influential critique of the same. Kim argues that Quine forces a false choice between traditional deductivist foundationalism and naturalized epistemology and contends that there are viable alternative epistemological projects. However it is suggested that Quine would reject these alternatives by reference to the same fundamental principles (underdetermination, indeterminacy of translation, extensionalism) that led him to reject traditional epistemology and propose naturalism as an alternative. Given this interpretation of Quine, it is essential that a successful critic of naturalism also examine Quine's aforementioned principles. The divide between naturalist and nonnaturalist epistemology turns out to be defined by the divide between more fundamental naturalist and nonnaturalist approaches to semantics.
