Applying a Process-Oriented Model of Cultural Competence to Behavioral Activation for Depression

Efforts to integrate cultural competence and evidence-based treatments (EBTs) typically take the form of cultural adaptations of EBTs, characterized by modifications to the existing treatment based on presumed cultural notions of a given race or ethnic group. Much less attention has been given to ways EBTs can integrate a process model of cultural competence, which focuses on what clinicians do in-session to identify and integrate key cultural factors for a given individual in the treatment. Our objective is to consider how a process model of cultural competence (Shifting Cultural Lenses) can be integrated with an EBT (Behavioral Activation). We present a theoretical rationale for integrating the SCL model with BA and illustrate this integration, which provides an additional approach to bringing culture to treatments and shows promise for identifying clinicians’ in-session behaviors that reflect cultural competence.     

The Role of Race in the Association between Corporal Punishment and Externalizing Problems: Does Punishment Severity Matter?

Parental corporal punishment is frequently associated with emotional and behavioral problems among youth. Some researchers propose that this association does not exist in African–American families, although the literature is mixed. Among recent studies, there is a lack of standardization in the measure of corporal punishment, which may help explain the inconsistent findings. The present study used a community sample (N = 106, 34 % African–American, 48 % female) to test for racial differences in the association between corporal punishment and youths’ aggression and delinquency, while examining different corporal punishment types separately by severity level. The three corporal punishment variables were spanking, severe corporal punishment (hitting and hitting with an object), and total corporal punishment (a composite of spanking, hitting, and hitting with an object). Regression analyses revealed that race moderated the association between corporal punishment and delinquency, although this moderation was contingent upon the corporal punishment variable. Specifically, severe corporal punishment and total corporal punishment were associated with delinquency only for Caucasian and not African–American youth. The model testing spanking and delinquency was not moderated by race. Additionally, race moderated the association between severe corporal punishment and youth aggression. Findings suggest that corporal punishment is associated with youth externalizing problems, but that this varies based upon race, severity of corporal punishment, and type of externalizing problem.     

The relationship between spoken language and speech and nonspeech processing in children with autism: a magnetic event‐related field study

It has been proposed that language impairments in children with Autism Spectrum Disorders (ASD) stem from atypical neural processing of speech and/or nonspeech sounds. However, the strength of this proposal is compromised by the unreliable outcomes of previous studies of speech and nonspeech processing in ASD. The aim of this study was to determine whether there was an association between poor spoken language and atypical event‐related field (ERF) responses to speech and nonspeech sounds in children with ASD (n = 14) and controls (n = 18). Data from this developmental population (ages 6–14) were analysed using a novel combination of methods to maximize the reliability of our findings while taking into consideration the heterogeneity of the ASD population. The results showed that poor spoken language scores were associated with atypical left hemisphere brain responses (200 to 400 ms) to both speech and nonspeech in the ASD group. These data support the idea that some children with ASD may have an immature auditory cortex that affects their ability to process both speech and nonspeech sounds. Their poor speech processing may impair their ability to process the speech of other people, and hence reduce their ability to learn the phonology, syntax, and semantics of their native language.     

Positive evidence for neonatal imitation: A general response,adaptive engagement

The study employed four gestural models using frame‐by‐frame microanalytic methods, and followed how the behaviours unfolded over time. Forty‐two human newborns (0–3 days) were examined for their imitation of tongue protrusion, ‘head tilt with looking up’, three‐finger and two‐finger gestures. The results showed that all three gesture groups were imitated. Results of the temporal analyses revealed an early and a later, second stage of responses. Later responses were characterized by a suppression of similar, but non‐matching movements. Perinatal imitation is not a phenomenon served by a single underlying mechanism; it has at least two different stages. An early phase is followed by voluntary matching behaviour by the neonatal infant.     

Comparing the Effects of Loving-Kindness Meditation (LKM), Music and LKM Plus Music on Psychological Well-Being

Loving-kindness meditation (LKM), a meditative practice directing caring feelings toward self and others, is a popular, evidence-base approach to increasing well-being. Music listening is also a popular form of emotion regulation used to enhance well-being. This interdisciplinary study evaluated a novel intervention called Convergence—combining LKM with accompanying classical guitar music—and its effects on adults’ well-being, mindfulness, compassion and self-compassion outcomes. Convergence was compared to active control groups LKM-only and Music-only regarding their relative effectiveness in improving these outcomes. Participants (N?=?78; aged 18 to 69?years; 90% females; recruited from the general public) were assigned to either the Convergence, LKM-only, or Music-only condition. Each condition received a 2-hour workshop, involving psychoeducation, three prerecorded meditations, and group enquiry and discussion. Participants were assessed at pre-program, post-program, and 4-week follow-up. Findings revealed that Convergence, LKM-only and Music-only were equally effective interventions, producing improvements in dependent variables with small effect sizes. There was no additive effect of the components when delivered together as Convergence. Significant correlations were found between the amount of home practice, and mindfulness and self-compassion at follow-up. LKM, music listening and Convergence all provide brief, evidence-based alternatives for improving well-being. Practical and theoretical implications are provided, as well as recommendations for future research.     

The extracellular protease matrix metalloproteinase-9 is activated by inhibitory avoidance learning and required for long-term memory

Matrix metalloproteinases (MMPs) are a family of extracellularly acting proteolytic enzymes with well-recognized roles in plasticity and remodeling of synaptic circuits during brain development and following brain injury. However, it is now becoming increasingly apparent that MMPs also function in normal, nonpathological synaptic plasticity of the kind that may underlie learning and memory. Here, we extend this idea by investigating the role and regulation of MMP-9 in an inhibitory avoidance (IA) learning and memory task. We demonstrate that following IA training, protein levels and proteolytic activity of MMP-9 become elevated in hippocampus by 6 h, peak at 12-24 h, then decline to baseline values by approximately 72 h. When MMP function is abrogated by intrahippocampal infusion of a potent gelatinase (MMP-2 and MMP-9) inhibitor 3.5 h following IA training, a time prior to the onset of training-induced elevation in levels, IA memory retention is significantly diminished when tested 1-3 d later. Animals impaired at 3 d exhibit robust IA memory when retrained, suggesting that such impairment is not likely attributed to toxic or other deleterious effects that permanently disrupt hippocampal function. In anesthetized adult rats, the effective distance over which synaptic plasticity is impaired by a single intrahippocampal infusion of the MMP inhibitor of the kind that blocks IA memory is approximately 1200 microm. Taken together, these data suggest that IA training induces a slowly emerging, but subsequently protracted period of MMP-mediated proteolysis critical for enabling long-lasting synaptic modification that underlies long-term memory consolidation.
