Altered lateralization of dorsal language tracts in 6‐week‐old infants at risk for autism

Altered structural connectivity has been identified as a possible biomarker of autism spectrum disorder (ASD) risk in the developing brain. Core features of ASD include impaired social communication and early language delay. Thus, examining white matter tracts associated with language may lend further insight into early signs of ASD risk and the mechanisms that underlie language impairments associated with the disorder. Evidence of altered structural connectivity has previously been detected in 6‐month‐old infants at high familial risk for developing ASD. However, as language processing begins in utero, differences in structural connectivity between language regions may be present in the early infant brain shortly after birth. Here we investigated key white matter pathways of the dorsal language network in 6‐week‐old infants at high (HR) and low (LR) risk for ASD to identify atypicalities in structural connectivity that may predict altered developmental trajectories prior to overt language delays and the onset of ASD symptomatology. Compared to HR infants, LR infants showed higher fractional anisotropy (FA) in the left superior longitudinal fasciculus (SLF); in contrast, in the right SLF, HR infants showed higher FA than LR infants. Additionally, HR infants showed more rightward lateralization of the SLF. Across both groups, measures of FA and lateralization of these pathways at 6 weeks of age were related to later language development at 18 months of age as well as ASD symptomatology at 36 months of age. These findings indicate that early differences in the structure of language pathways may provide an early predictor of future language development and ASD risk.     

Reconceptualizing adult attachment relationships: A network perspective

This article explores attachment relationships from a network theory perspective: Correlations among behaviors, beliefs, and feelings related to attachment are hypothesized to stem from causal relations. The authors used two data sets that assessed relationships with four attachment figures (mother, father, romantic partner, and best friend) using the Relationship Structures Questionnaire. Separate networks (Gaussian Graphical Models) were estimated based on 10 items for each attachment figure. Across networks in Study 1 (N = 310), items related to anxiety, seeking support, and discomfort disclosing feelings clustered with other items from their respective domains; a trust‐related item bridged the clusters. Study 2 replicated these findings in a larger and more diverse sample (N = 3,710). The potential of network analysis for advancing the study of attachment is discussed.

Impulsivity and Behavior-Dependent Life Events Mediate the Relationship of Reward Sensitivity and Depression,but Not Hypomania,Among at-Risk Adolescents

Both reward sensitivity and impulsivity are related to the development and course of bipolar spectrum disorders (BSDs) and have been implicated in other disorders and negative functional outcomes such as substance abuse, obesity, suicidal behaviors, and risk-taking. Furthermore, according to the transactional component of the Behavioral Approach System (BAS)/reward hypersensitivity theory of BSDs, people with reward hypersensitivity should experience more BAS-relevant events, and thus, are more vulnerable to mood symptoms and episodes via stress generation. Impulsivity may exacerbate stress generation in individuals at risk for BSDs based on exhibiting reward hypersensitivity. The current study examined whether impulsivity explained the generation of stress and subsequent mood symptoms beyond what is explained by reward sensitivity alone. Participants were 131 Moderate BAS and 216 High BAS sensitivity adolescents (M = 18.43 years, SD = 1.40), who completed baseline measures of reward sensitivity and impulsivity, as well as follow-up measures of life events and mood symptoms. Results from linear regression analyses indicated that higher baseline impulsivity predicted behavior-dependent, but not behavior-independent, life events. Furthermore, path analyses suggested that the effect of BAS group on depression symptoms at next follow-up was partly explained via the indirect effect of impulsivity and negative behavior-dependent life events. We did not find these effects for behavior-independent or positive-dependent events or for prediction of hypomanic symptoms. The findings suggest that impulsivity may account for stress generation of negative events that precede depression.     

Wittgenstein on Understanding as a Mental State

In trying to make clear whether understanding is a mental state Wittgenstein asks a series of questions about the timing and duration of understanding. These questions are awkward, and they have posed a great challenge for commentators. In this paper I review the interpretations by Mole and by Baker and Hacker, and point out their problems. I then offer a new interpretation which shows (1) that a “mental state” in this context means a state of consciousness, (2) that Wittgenstein's questions are intended to elicit the grammars of the words “understand” and a “state of consciousness”, (3) that, in this way, he clearly shows that understanding is not a state of consciousness and (4) that he also provides a therapy to dissolve the problem.     

Factor analysis and validation of a self-report measure of impaired fear inhibition

Difficulties with inhibiting fear have been associated with the emergence of anxiety problems and poor response to cognitive–behavioural treatment. Fear inhibition problems measured using experimental paradigms involving aversive stimuli may be inappropriate for vulnerable samples and may not capture fear inhibition problems evident in everyday life. We present the Fear Inhibition Questionnaire (FIQ), a self-report measure of fear inhibition abilities. We assess the FIQ’s factor structure across two cultures and how well it correlates with fear inhibition indices derived experimentally. Adolescent participants from Hong Kong and England completed the FIQ, with the English participants also completing a conditioning and extinction task to assess fear inhibition problems. Across both cultures, the FIQ showed a single factor structure and low FIQ scores, or worse fear inhibition problems, were associated with self-reports of heightened anxiety. Correlation of FIQ scores with experimental indices, whilst controlling for anxious symptoms, suggests that the FIQ represents a valid and unique measure of fear inhibition abilities. The FIQ might be used to assess more ecologically valid fear inhibition problems particularly amongst people who have or who are at risk of anxiety diagnoses.     

Cognitive reappraisal attenuates the association between depressive symptoms and emotional response to stress during adolescence

Depression is associated with increased emotional response to stress. This is especially the case during the developmental period of adolescence. Cognitive reappraisal is an effective emotion regulation strategy that has been shown to reduce the impact of emotional response on psychopathology. However, less is known about whether cognitive reappraisal impacts the relationship between depressive symptoms and emotional responses, and whether its effects are specific to emotional reactivity or emotional recovery. The current study examined whether cognitive reappraisal moderated the relationship between depressive symptoms and trait or state measures of emotional reactivity and recovery. A community sample of 127 adolescents (M-age?=?15.28; 49% female, 47% Caucasian), at an age of risk for depression, completed self-report measures of trait emotional responding and depressive symptoms. In addition, they completed an in vivo social stress task and were assessed on state emotional reactivity and recovery from the stressor. Findings suggested that cognitive reappraisal was associated with an attenuated impact of depressive symptoms on trait and state emotional recovery. These results provide evidence that cognitive reappraisal may be an effective strategy for improving some aspects of emotional responding in relation to depressive symptoms among adolescents.     

Maternal experience of their infants’ crying in the context of war trauma: Determinants and consequences

We examined, first, how prenatal maternal mental health and war trauma predicted mothers’ experience of their infant crying, indicated by emotions, cognitions, and behavior; and second, how these experiences influenced the mother–infant interaction and infant development. Participants were 511 Palestinian mothers from the Gaza Strip, reporting their war trauma, symptoms of posttraumatic stress disorder (PTSD), depression, and perceived stress during pregnancy (Time 1). They reported experiences of infant crying at 4 months (Time 2), and the mother–infant interaction and infant sensorimotor and language development at 12 months of infants’ age (Time 3). Results revealed that maternal mental health problems, but not war trauma, were important to experiences of infant crying. A high level of PTSD symptoms predicted negative emotions evoked by infant crying, and high depressive symptoms predicted low active and positive responses to crying. Unexpectedly, high prenatal perceived stress predicted high active and positive responsiveness. Concerning the consequences, mothers’ sensitive interpretation of infant crying predicted optimal infant sensorimotor development, and mothers’ active and positive responses predicted high emotional availability in mother–infant interaction. Crying is the first communication tool for infants, and mothers’ sensitive responses to crying contribute to infant well-being. Therefore, reinforcing mother's optimal responses is important when helping war-affected dyads.     

What Prevents Adolescents from Seeking Help After a Suicide Education Program?

Perceived barriers to help-seeking among adolescents attending a suicide education program were examined. A total of 854 high school students in Colorado completed one of two questionnaires, measuring barriers to help-seeking for self or friend. The most prominent barriers for self were: inability to discuss problems with adults, self-overconfidence, fear of hospitalization, and lack of closeness to school adults. The most prominent barriers for troubled friends were: friendship concerns, unapproachability of school adults, fear of friend's hospitalization, and underestimating friend's problems. Results reveal multiple constraints limiting the program's utilization, supporting the need for comprehensive system approaches to suicide prevention.
