White matter maturation supports the development of reasoning ability through its influence on processing speed

The structure of the human brain changes in several ways throughout childhood and adolescence. Perhaps the most salient of these changes is the strengthening of white matter tracts that enable distal brain regions to communicate with one another more quickly and efficiently. Here, we sought to understand whether and how white matter changes contribute to improved reasoning ability over development. In particular, we sought to understand whether previously reported relationships between white matter microstructure and reasoning are mediated by processing speed. To this end, we analyzed diffusion tensor imaging data as well as data from standard psychometric tests of cognitive abilities from 103 individuals between the ages of 6 and 18. We used structural equation modeling to investigate the network of relationships between brain and behavior variables. Our analyses provide support for the hypothesis that white matter maturation (as indexed either by microstructural organization or volume) supports improved processing speed, which, in turn, supports improved reasoning ability.     

Cultural differences in emotion regulation during self-reflection on negative personal experiences

Reflecting on negative personal experiences has implications for mood that may vary as a function of specific domains (e.g., achievement vs. interpersonal) and cultural orientation (e.g., interdependence vs. independence). This study investigated cultural differences in the social-cognitive and affective processes undertaken as Easterners and Westerners reflected on negative interpersonal and performance experiences. One hundred Asian Americans and 92 European-American college students were randomly assigned to one of three conditions: interpersonal rejection, achievement failure, or a control condition. Results revealed that Asian Americans experienced greater distress than European Americans after self-reflecting over a failed interpersonal experience, suggesting cultural sensitivity in the relational domain. Consistent with theoretical predictions, analysis of the social cognitive and affective processes that participants engaged in during self-reflection provided some evidence that self-enhancement may buffer distress for European Americans, while emotion suppression may be adaptive for Asian Americans.     

How do social fears in adolescence develop? Fear conditioning shapes attention orienting to social threat cues

Social fears emerging in adolescence can have negative effects on emotional well-being. Yet the mechanisms by which these risks occur are unknown. One possibility is that associative learning results in fears to previously neutral social stimuli. Such conditioned responses may alter subsequent processing of social stimuli. We used a novel conditioning task to examine how associative processes influence social fear and attention orienting in adolescents. Neutral photographs were paired with socially rewarding or aversive stimuli during conditioning; a dot-probe task then assessed biases in attention orienting. The social conditioning task modified subjective ratings of the neutral stimuli. Moreover, for the neutral stimulus that was paired with the aversive stimulus, the strength of conditioning showed a relationship with subsequent attentional vigilance. The findings elucidate mechanisms by which negative peer experiences during adolescence may affect emotional processing.     

Attitudes towards psychotherapy manuals among clinicians treating eating disorders

Clinicians have relatively low uptake and implementation of evidence-based psychotherapies for the eating disorders, and this problem appears to be associated with low use of manualized approaches. This study examines clinicians' positive and negative attitudes to manuals, and possible beliefs and emotional factors that might drive those attitudes. The participants were 125 psychological therapists working with eating-disordered patients. Each completed standardised measures of attitudes to manuals and emotional states. A number of beliefs about the content of manuals were associated with both positive attitudes to the outcome of treatment and negative attitudes to their impact on the treatment process. In addition, a more positive mood was associated with more positive attitudes. Suggestions are made regarding how attitudes might be made more positive, in order to facilitate the use of evidence-based therapies for eating disorders.     

Cognitive bias modification of interpretations: A viable treatment for child and adolescent anxiety?

Anxiety disorders in children and adolescents are common and impairing. As many patients do not benefit from – or have difficulties accessing – frontline treatments, novel, effective and easy-to-deliver interventions are needed. Cognitive Bias Modification of Interpretations (CBM-I) training has been used to treat adult anxiety disorders. CBM-I methods train individuals to endorse benign rather than negative resolutions of ambiguous cues. Developmental extensions of CBM-I are important for several reasons. First, implementing CBM-I in symptomatic children and adolescents may facilitate early preventative gains. Second, as training uses simple learning mechanisms, CBM-I may reflect a developmentally-suitable strategy for shaping adaptive processing styles. Third, as this age range involves protracted neurocognitive maturation and associated plasticity, administering CBM-I early could drive powerful, long-lasting benefits for emotional development. Finally, data from CBM-I studies could inform the cognitive mechanisms involved in the genesis of early-emerging anxiety. This paper provides the first organised review of CBM-I studies conducted in children and adolescents, and contains suggestions for future research that may help realise the therapeutic potential of early CBM-I interventions.     

The Interrater Reliability of Subjective Assessments of the Babinski Reflex

The Babinski reflex is a clinical diagnostic tool; however, the interrater reliability of this tool is currently greatly contested. A comparison between rater groups with objective measurements of the Babinski reflex was therefore conducted. Fifteen recorded Babinski reflexes were assessed by 12 neurologists and 12 medical students as being either pathological or nonpathological. Kinematic and electromyographic variables were collected and used to assess which aspects of the Babinski reflex predict classification. Substantial interrater agreement within the neurologist and student groups (κ = .72 and .67, respectively) was shown; however, there were some differing aspects between what neurologists and students used to assess the reflex as determined by objective kinematic measurements.     

Mindful Parenting and Emotion Socialization Practices: Concurrent and Longitudinal Associations

Caregivers play a crucial role in the socialization of youth emotion understanding, competence, and regulation, which are implicated in youth social and emotional health; however, there is less understanding of parental psychosocial or cognitive factors, like mindful parenting, that may be associated with the use of particular emotion socialization (ES) strategies. This study tests a model of the cross‐sectional and short‐term longitudinal associations between mindful parenting and supportive and nonsupportive ES strategies in a community sample of parents (N = 246; 63.8% mothers) of youth ranging from ages 3–12. Caregivers reported on mindful parenting and ES strategies at two time points 4 months apart. The structural equation model indicated that higher levels of mindful parenting are positively related to supportive ES responses and negatively related to nonsupportive ES responses both concurrently and over time. The longitudinal association between mindful parenting and nonsupportive, but not supportive, ES was marginally larger for fathers as compared to mothers. Given the documented impact of ES strategies on youth emotional and behavioral outcomes and interventions emerging to educate parents about how to provide a healthy emotional atmosphere, incorporating a focus on mindful parenting strategies may provide one pathway to increase supportive responses and decrease nonsupportive ones.
