Progress disseminating and implementing evidence-based psychological treatments (EBPTs) for the anxiety disorders has been gradual. To date, the dominant approach for promoting the uptake of EBPTs in clinical settings has been to target the education and training of mental health providers, with many consumers remaining unaware of the potential benefits of EBPTs for anxiety disorders. Direct-to-consumer (DTC) marketing may be a promising vehicle for increasing EBPT utilization rates in the treatment of anxiety disorders. This paper provides an overview of the rationale and important considerations for applying DTC efforts to promote evidence-based care in the treatment of anxiety disorders, and reviews current DTC efforts in this area, including resources on the Internet and other media and in-person events. We conclude with recommendations for future efforts in the DTC marketing of EBPTs for the anxiety disorders, including the need for increased funding and grassroots efforts to inform consumers about anxiety disorders and their most effective treatments.

We examined whether error monitoring, operationalized as the degree to which individuals slow down after committing an error (i.e., posterror slowing), is differentially important in the learning of rule-based versus information-integration category structures. Rule-based categories are most efficiently solved through the application of an explicit verbal strategy (e.g., "sort by color"). In contrast, information-integration categories are believed to be learned in a trial-by-trial, associative manner. Our results indicated that posterror slowing predicts enhanced rule-based but not information-integration category learning. Implications for multiple category-learning systems are discussed.

BACKGROUND: Advanced paternal age (APA) is associated with increased risk for schizophrenia, but its effect on treatment response has not been longitudinally studied. METHODS: Association of parental ages at the time of the child's birth with age of onset, initial symptom severity and treatment response (to placebo and three different weight-based doses of paliperidone ER) in adolescents with schizophrenia was assessed in a post-hoc analysis using data from a 6-week double-blind study, the primary results of which are published (NCT00518323). RESULTS: The mean (SD) paternal age was 29.2 (6.2) years, range (16-50) and maternal age was 26.8 (5.7) years, range (17-42) at childbirth for the 201 adolescents (ages 12-17years) included in the analysis. While parental ages were uncorrelated with age of onset or initial symptom severity, both maternal and paternal ages showed significant effects on treatment response (p<0.03) of all paliperidone ER arms versus placebo. Paternal age was significantly correlated to improvement in positive symptoms and maternal age significantly related to negative symptoms, although only paternal age remained significantly associated with the treatment response in analyses that included both parents' ages. CONCLUSIONS: APA was associated with greater treatment response to both paliperidone ER and placebo, but not to age of onset or initial symptom severity in adolescents with schizophrenia. The results support the contention that APA-related schizophrenia has distinct underpinnings from other cases. Further studies are required to explore the role of genetic and environmental factors, and their interactions, in treatment response in this complex disorder.

Effective navigation of the social world relies on the correct interpretation of facial emotions. This may be particularly important in formative years. Critically, literature examining the emergence of face processing in youth (children and adolescents) has focused on the neural and behavioral correlates of processing adult faces, which are relationally different from youth participants, and whose facial expressions may convey different meaning than faces of their peers. During a functional magnetic resonance imaging (fMRI) scan, we compared concurrent neural and behavioral responses as youth (N=25) viewed validated, emotionally varied (i.e., anger, fear, happy, and neutral) adult and child face stimuli. We observed that participants made fewer errors when matching adult, compared to child, face stimuli, and that while similar brain regions were involved in processing both adult and child faces, activation in the face processing neural network was greater for adult than child faces. This was true across emotions, and also when comparing neutral adult versus neutral child faces. Additionally, a valence by stimuli-type effect was observed within the amygdala. That is, within adult face stimuli, negative and neutral face stimuli elicited the largest effects, whereas within child face stimuli, happy face stimuli elicited the largest amygdala effects. Thus, heightened engagement of the amygdala was observed for happy child and angry adult faces, which may reflect age-specific salience of select emotions in early life. This study provides evidence that the relational age of the perceived face influences neural processing in youth.

OBJECTIVE: Pediatric bipolar disorder involves poor social functioning, but the neural mechanisms underlying these deficits are not well understood. Previous neuroimaging studies have found deficits in emotional face processing localized to emotional brain regions. However, few studies have examined dysfunction in other regions of the face processing circuit. This study assessed hypoactivation in key face processing regions of the brain in pediatric bipolar disorder. METHOD: Youth with a bipolar spectrum diagnosis (n = 20) were matched to a nonbipolar clinical group (n = 20), with similar demographics and comorbid diagnoses, and a healthy control group (n = 20). Youth participated in a functional magnetic resonance imaging (fMRI) scanning which employed a task-irrelevant emotion processing design in which processing of facial emotions was not germane to task performance. RESULTS: Hypoactivation, isolated to the fusiform gyrus, was found when viewing animated, emerging facial expressions of happiness, sadness, fearfulness, and especially anger in pediatric bipolar participants relative to matched clinical and healthy control groups. CONCLUSIONS: The results of the study imply that differences exist in visual regions of the brain's face processing system and are not solely isolated to emotional brain regions such as the amygdala. Findings are discussed in relation to facial emotion recognition and fusiform gyrus deficits previously reported in the autism literature. Behavioral interventions targeting attention to facial stimuli might be explored as possible treatments for bipolar disorder in youth.

In reconsolidation studies, memories are typically retrieved by an exposure to a single conditioned stimulus (CS). We have previously demonstrated that reconsolidation processes are CS-selective, suggesting that memories retrieved by the CS exposure are discrete and reconsolidate separately. Here, using a compound stimulus in which two distinct CSs are concomitantly paired with the same aversive unconditioned stimulus (US), we show in rats that reexposure to one of the components of the compound CS triggers extinction or reconsolidation of the other component. This suggests that the original training conditions play a critical role in memory retrieval and reconsolidation.
