Optimizing inhibitory learning during exposure therapy

Prevailing models of exposure therapy for phobias and anxiety disorders construe level of fear throughout exposure trials as an index of corrective learning. However, the evidence, reviewed herein, indicates that neither the degree by which fear reduces nor the ending fear level predict therapeutic outcome. Developments in the theory and science of fear extinction, and learning and memory, indicate that 'performance during training' is not commensurate with learning at the process level. Inhibitory learning is recognized as being central to extinction and access to secondary inhibitory associations is subject to influences such as context and time, rather than fear during extinction training. Strategies for enhancing inhibitory learning, and its retrieval over time and context, are reviewed along with their clinical implications for exposure therapy and directions for future research.     

Association Between Body Mass Index and Motor Competence in Santal Children of Purulia District,India

The purpose of this study was to evaluate the relationship between body mass index and motor competence in Santal children 5–12 years old. A total of 816 Santal children were studied. Children's adiposity status was assessed by body mass index (BMI) for age z-score based on World Health Organization reference data. Motor competence was measured using the Bruininks-Oseretsky Test of Motor Competence (BOT-2). There was no significant difference in mean BMI z-score between Santal boys (0.13 ± 0.07) and girls (?0.14 ± 0.07). Healthy weight (HW) children scored higher (p < .05) in some individual motor subtests (bilateral competence, balance, running speed and agility, upper limb competence, and strength) and in total BOT-2 score (p < .05) compared with scores for underweight (UW) and overweight (OW) children. Nonlinear regression analysis showed that BMI is a significant independent predictor of motor competence (p < .01). Motor competence showed a curvilinear relationship with BMI-z-score, with the lowest point motor scores in strength and upper limb competence (p < .05) for both UW and OW children compared to HW children who scored highest. The results also indicated that gross motor skills, but not fine motor skills, were poorer among children who were UW or OW compared with HW children.     

Total sleep deprivation impairs the encoding of trace-conditioned memory in the rat

Sleep may help consolidate the information of certain memories, though its benefits in the consolidation of trace-conditioned memory still remain elusive. We investigated the effect of sleep deprivation on trace learning in male wistar rats. Rats were trained for trace conditioning and the number of head entries into liquid dispenser was accounted as an outcome measure of trace-learning. For training and testing, 75 presentations of conditioned stimulus (CS) (light) and unconditioned stimulus (US) (juice) were offered in five sessions (15 presentations/session; with 5 min inter-session gap). The duration of CS and US stimuli were 15 and 20s respectively, with 5s trace delay between stimuli and 20s condition delay between each presentation. The animals were divided randomly into three groups soon after training, sleep deprived (SD) (n=8), non-SD (NSD) (n=8) and stress control (n=5) groups. The animals of NSD and control groups were left undisturbed, while SD animals were sleep deprived for 6h after training. The learning of trace-conditioned task was examined on following days. We observed that SD rats poked approximately 63% less than NSD and control groups (p<0.001) to obtain juice on testing day. Also, the NSD rats exhibited significant positive correlation in number of head entries during the training and testing days; while the SD rats showed no significant correlation. The results demonstrate that SD animals had difficulties to associate CS with US and suggest that sleep deprivation soon after training impairs the encoding of trace memory.     

Pitch direction ability predicts melodic perception in autism

Individuals with autism spectrum disorders (ASDs) often present atypical auditory perception. Previous work has reported both enhanced low-level pitch discrimination and superior abilities to detect local pitch structure on higher-level melodic tasks in ASD. However, it is unclear how low and high levels of auditory perception are related in ASD or typical development (TD), or how this relationship might change across development and stimulus presentation rates. To these aims, in the present study, children with ASD and TD were tested on a low-level pitch direction discrimination task and a high-level melodic global-local task. Groups performed similarly on both of these auditory tasks. Moreover, individual differences in low-level pitch direction ability predicted performance on the higher-level global-local task, with a stronger relationship in ASD. Age did not affect the relationship between low-level and high-level pitch performance in either ASD or TD. However, there was a more positive effect of age on the high-level global-local task performance in TD than ASD. Finally, there was no effect of stimulus rate on the relationship between low-level and high-level pitch performance in either group. These findings provide a better understanding of how perception is associated across levels of processing in ASD versus TD. This work helps to better understand individual differences in auditory perception and to refine ASD phenotypes.     

Bridging the Divide Between Psychodynamic and Behavioral Approaches for Children with Oppositional Defiant Disorder

ABSTRACT

Oppositional defiant disorder (ODD) is one of the primary reasons youth are referred to mental health services. Disruptive behavior disorders such as ODD are heterogeneous in their presentation, developmental trajectories, and treatment needs. Given the high attrition rates in child psychotherapy in general, there is a need for a range of interventions tailored to meet the unique needs of each family to help increase familial engagement and positive outcomes for children with ODD.

This article outlines composite clinical case material of a child with ODD who was treated with Regulation Focused Psychotherapy for Children (RFP-C), a manualized, psychodynamic intervention for ODD. The case presented is then reconceptualized from a behavioral parent training perspective. This approach uses parent training to encourage positive parenting practices and reduce coercive reinforcement cycles. The case material and its reconceptualization are followed by a discussion of the distinctions between psychodynamic and behavioral approaches to children with ODD. An integrated psychotherapy approach is proposed, and the benefits and challenges of psychotherapy integration are discussed.     

Culturally sensitive therapy? Examining the practice of cross‐cultural family therapy

This article is drawn from a research project that examines cross‐cultural family therapy sessions in order to consider what constitutes culturally sensitive practice. A discourse analytic approach was adopted in the analysis of three sessions from two families where the family and the therapists originated from different ethnic backgrounds. This article is based around part of the research findings connected to one of the families, and focuses upon the ways in which ‘culture’ is talked about in therapy (the term ‘culture’ will be referred to in inverted commas in order to acknowledge its complexity as is emphasized in this article). This allows for an examination of the cultural assumptions that we hold as therapists, which are enacted in therapy with effects on all participants and upon the course of the therapy. The value of qualitative research methods in examining the cultural assumptions we bring to therapy is highlighted as one way of improving culturally sensitive therapeutic practice, especially with regard to therapist reflexivity.     

The role of exploratory buying behavior tendencies in choices made for others

We examine whether the consumer trait of exploratory buying behavior tendencies (EBBT; Baumgartner, H., and Steenkamp, J.E.M. (1996). Exploratory consumer buying behavior: Conceptualization and measurement. International Journal of Research in Marketing, 13, 121–137.) can influence even choices made for others. The results of three experiments in a gift-giving context show that high (vs. low) EBBT individuals have greater salience of hedonic search motives and consequently form more diverse consideration sets while purchasing a gift. Further, when working with a specific gift budget, high EBBT consumers are more likely to diversify their gift choices by buying a greater number of relatively lower-priced gift items. We also find that the effects of the EBBT trait are significantly attenuated when the regulatory focus of the person making the gift decision is one of prevention rather than promotion. Discussion focuses on implications and future research directions regarding the relationship between exploratory buying behavior tendencies and consumer decision-making.
