Neural coding of formant-exaggerated speech in the infant brain

Speech scientists have long proposed that formant exaggeration in infant-directed speech plays an important role in language acquisition. This event-related potential (ERP) study investigated neural coding of formant-exaggerated speech in 6-12-month-old infants. Two synthetic /i/ vowels were presented in alternating blocks to test the effects of formant exaggeration. ERP waveform analysis showed significantly enhanced N250 for formant exaggeration, which was more prominent in the right hemisphere than the left. Time-frequency analysis indicated increased neural synchronization for processing formant-exaggerated speech in the delta band at frontal-central-parietal electrode sites as well as in the theta band at frontal-central sites. Minimum norm estimates further revealed a bilateral temporal-parietal-frontal neural network in the infant brain sensitive to formant exaggeration. Collectively, these results provide the first evidence that formant expansion in infant-directed speech enhances neural activities for phonetic encoding and language learning.     

Mother-to-Daughter Disclosure After Divorce: Are There Costs and Benefits?

To investigate the association between post-divorce mother-to-daughter disclosure regarding sensitive topics and adolescent daughters' adjustment and closeness to mother, we collected data from 62 adolescent girls within the first two years after their mother's divorce. Analyses revealed that most mothers in the current sample have disclosed to their daughters to some degree about the five sensitive topic areas studied. In accordance with structural family systems theory, we found that detailed mother-to-daughter disclosures regarding financial concerns, negativity toward ex-husband, job ups-and-downs, and personal concerns were clearly associated with greater daughter psychological distress, but not with greater feelings of mother-daughter closeness, as existing retrospective research would have predicted. Daughters' worrying about their mothers explained (mediated) the link between maternal disclosure and daughter's distress to some extent. We discuss methodological issues as well as the valuable contributions that future, more contextualized research could make to understanding the conditions under which detailed mother-to-adolescent disclosure may be more or less risky.     

The Role of Overt and Covert Avoidance Strategies in Generalized Anxiety Disorder Symptoms and Fear of Emotion

Models of generalized anxiety disorder (GAD) have largely focused on the role of cognitive (i.e. covert) processes in the maintenance of GAD symptoms, including cognitive avoidance (e.g., thought suppression). Researchers have begun to investigate more systematically the role of overt avoidance behaviors in GAD symptoms and processes. However, the contribution of both overt and covert avoidance strategies in GAD symptoms and emotional processes has not been examined yet. The aim of the present study was to investigate if both overt and covert avoidance strategies are related to (Objective 1) and make a unique contribution in the explanation of the variance of (Objective 2) GAD symptoms, chronic worry and emotional processes (i.e. fear of emotion). Individuals high in chronic worry and GAD symptoms (N?=?113) recruited from the community completed measures of the study variables. Greater use of overt and covert avoidance were both related to greater GAD symptoms, worry severity and fear of emotion. However, covert avoidance was the only unique correlate of GAD symptoms, worry severity and fear of emotion. The results suggest that covert avoidance makes a greater contribution to GAD symptoms and fear of emotion, than does overt avoidance. Future studies are needed to understand how overt avoidance behaviors fit into theoretical models of chronic worry and GAD.

     

What’s in a name? Intolerance of uncertainty,other uncertainty-relevant constructs,and their differential relations to worry and generalized anxiety disorder*

A number of studies have examined the association of intolerance of uncertainty (IU) to trait worry and generalized anxiety disorder (GAD). However, few studies have examined the extent of overlap between IU and other psychological constructs that bear conceptual resemblance to IU, despite the fact that IU-type constructs have been discussed and examined extensively within psychology and other disciplines. The present study investigated (1) the associations of IU, trait worry, and GAD status to a negative risk orientation, trait curiosity, indecisiveness, perceived constraints, self-oriented and socially prescribed perfectionism, intolerance of ambiguity, the need for predictability, and the need for order and structure and (2) whether IU is a unique correlate of trait worry and of the presence versus absence of Probable GAD, when overlap with other uncertainty-relevant constructs is accounted for. N = 255 adults completed self-report measures of the aforementioned constructs. Each of the constructs was significantly associated with IU. Only IU, and a subset of the other uncertainty-relevant constructs were correlated with trait worry or distinguished the Probable GAD group from the Non-GAD group. IU was the strongest unique correlate of trait worry and of the presence versus absence of Probable GAD. Indecisiveness, self-oriented perfectionism and the need for predictability were also unique correlates of trait worry or GAD status. Implications of the findings are discussed, in particular as they pertain to the definition, conceptualization, and cognitive-behavioral treatment of IU in GAD.     

A preliminary investigation of impulsivity in generalized anxiety disorder

Few studies have examined the association between impulsivity and generalized anxiety disorder (GAD). This study examined whether individuals with probable GAD display impulsivity in a particular way, and the extent to which impulsivity uniquely predicts GAD severity and GAD status, over and above intolerance of uncertainty (IU), a key cognitive factor in GAD. Individuals with (n = 63) and without (n = 77) probable GAD completed self-report measures of impulsivity and IU. Results revealed that elevations in the severity of GAD symptoms and in IU were associated with impulsive actions in the face of negative affect (i.e., negative urgency), but also greater premeditation and lower “functional” impulsivity (i.e., the ability to take quick action when it is advantageous to do so). Impulsivity led to an increment in the prediction of GAD symptoms and GAD status, over and above IU. Negative urgency and lower functional impulsivity were significant unique predictors of GAD severity or GAD status. The findings highlight a need to consider impulsivity in theories that implicate intolerance of negative affect and uncertainty in excessive and uncontrollable worry.     

Connections Between Family Communication Patterns,Person‐Centered Message Evaluations,and Emotion Regulation Strategies

In this study, we theorize that family communication patterns (FCPs) and 2 emotion regulation strategies (reappraisal and suppression) explain variations in person‐centered (PC) supportive message evaluations. Specifically, we forward an emotion regulation model that predicts reappraisal and suppression will mediate the relation between FCPs and PC message evaluations. Results (N = 361) suggest that conversation orientation positively predicted reappraisal and negatively predicted suppression; conformity orientation positively predicted suppression only. Reappraisal positively and suppression negatively predicted the extent to which people discriminated among PC message evaluations. Reappraisal also mediated the relation between conversation orientation and PC message evaluations. These results have implications for how capable people are to evaluate and ultimately profit from beneficial support when coping with negative emotions.     

Post-Divorce Maternal Disclosure and the Father–Adolescent Relationship: Adolescent Emotional Autonomy and Inter-Reactivity as Moderators

Utilizing longitudinal data from a project that examined the post-divorce lives of mothers and adolescents, we addressed two questions: (a) Does exposure to negative maternal disclosure about the ex-husband/father impact adolescents’ perceptions of the father-adolescent relationship? and (b) Are adolescents with low emotional autonomy and high emotional inter-reactivity especially vulnerable? Participants were 154 adolescents, who ranged in age from 12 to 18 years at wave two. Although there was no significant bivariate association between maternal negative disclosure about the father and father-adolescent relationship quality, boys’ level of emotional autonomy and emotional inter-reactivity moderated the association between maternal negative disclosure and the father–adolescent relationship. As hypothesized, boys with lower levels of emotional autonomy and higher levels of emotional inter-reactivity vis-à-vis their mothers perceived a lower quality of relationship with their father when their mother frequently disclosed negatively about the ex-husband/father. Research and applied implications are discussed.     

Communication and Understanding in Parent–Adolescent Relationships

This research examined communication and parent–adolescent understanding, including understanding about family conflicts, adolescent self‐concepts, and immediate thoughts (or “empathic accuracy”). Fifty parent–adolescent triads completed questionnaires, held a discussion, and reported on immediate thoughts during the discussion using video‐assisted recall methods. Alternative measures of understanding produced distinct results. Parental understanding of the child's self‐concept was associated with frequent and open communication, high parent–child relationship satisfaction, and a strong child self‐concept. Parental understanding of conflict perceptions was associated with high conformity and low relationship satisfaction. Parental understanding of the immediate thoughts of children was quite low overall and was not consistently related to communication, relationship satisfaction, or child self‐concept. The results suggest that alternative measures of understanding reflect different family processes.
