The moment‐to‐moment pitch dynamics of child‐directed speech shape toddlers’ attention and learning

Young children have an overall preference for child‐directed speech (CDS) over adult‐directed speech (ADS), and its structural features are thought to facilitate language learning. Many studies have supported these findings, but less is known about processing of CDS at short, sub‐second timescales. How do the moment‐to‐moment dynamics of CDS influence young children's attention and learning? In Study 1, we used hierarchical clustering to characterize patterns of pitch variability in a natural CDS corpus, which uncovered four main word‐level contour shapes: ‘fall’, ‘rise’, ‘hill’, and ‘valley’. In Study 2, we adapted a measure from adult attention research—pupil size synchrony—to quantify real‐time attention to speech across participants, and found that toddlers showed higher synchrony to the dynamics of CDS than to ADS. Importantly, there were consistent differences in toddlers’ attention when listening to the four word‐level contour types. In Study 3, we found that pupil size synchrony during exposure to novel words predicted toddlers’ learning at test. This suggests that the dynamics of pitch in CDS not only shape toddlers’ attention but guide their learning of new words. By revealing a physiological response to the real‐time dynamics of CDS, this investigation yields a new sub‐second framework for understanding young children's engagement with one of the most important signals in their environment.     

The danger in deception: oedipal betrayal and the assault on truth

Certain potential precursors to heterosexual women's experience of partner infidelity are explored as these dynamics unfold within the oedipal crisis-the "betrayal" by the oedipal objects. As each child moves into the oedipal phase, he or she comes to recognize not only desire for the mother, but the mother's desire for the father. A doubling of this experience of "deception," encountered first in relation to the mother, and then repeated with the father, may be especially pronounced for a girl, as she is likely to inhabit more fully her bisexual potential in negotiating the expected shift of object choice from mother to father. "Deceived" by her primary maternal oedipal object, a girl sets forth toward her paternal oedipal object with "fidelity" already an issue, and with faith in her mind's ability to determine reality already shaken. Undermined trust in self and other is the context in which she begins the oedipal relation to her heterosexual object. This path is quite distinct from that traveled by the heterosexual boy. Clinical material illustrates the assault on one's mind, on one's confidence to determine what is true, that is a central aspect of both oedipal and adult betrayal.     

The importance of perceived autonomy support for the psychological health and work satisfaction of health professionals: Not only supervisors count, colleagues too!

Previous studies show that supervisors?? autonomy-supportive style predicts greater psychological health (Baard et al. in J Appl Soc Psychol 34:2045?C2068, 2004; Blais and Brière 1992; Lynch et al. in Prof Psychol Res Pract 36:415?C425, 2005) and lower psychological distress (Deci et al. in Personal Soc Psychol Bull 27:930?C942, 2001). The goal of the present study is to extend these results and investigate the contribution of colleagues?? perceived autonomy support in the prediction of health professionals?? work satisfaction and psychological health. The combined impact of supervisors?? and colleagues?? perceived autonomy support is also examined. A sample of 597 health professionals from the province of Quebec (Canada) completed a questionnaire, which included measures of perceived supervisors?? and colleagues?? autonomy support and outcome variables. Results confirm that supervisors?? and colleagues?? perceived autonomy support predict health professionals?? work satisfaction and psychological health. Results also show that colleagues?? perceived autonomy support adds to the prediction of health professionals?? work satisfaction, subjective well-being, and suicidal ideation above and beyond supervisors?? perceived autonomy support.     

Emotional health predictors of substance use initiation during middle school

This study aimed to evaluate whether emotional health factors, including anxiety and depression, stress, and social support, are associated with earlier youth initiation of alcohol and illicit substances during middle school (from the sixth to the eighth grade). Data for this study were from the Developmental Pathways Project, a longitudinal study of 521 youth sampled from the Seattle Public Schools. Discrete time survival analyses were used to assess the effects of depression, anxiety, stress, and support on initiation of substance use, measured every 6 months at five time points between sixth and eighth grade. Youth who had initiated prior to sixth grade had significantly higher levels of depressive symptoms. In multivariate survival analyses controlling for child race/ethnicity, gender, and socioeconomic status, and accounting for conduct problems, youth who reported higher levels of separation anxiety/panic symptoms were at decreased risk for early alcohol initiation. Children with higher levels of perceived teacher support had a significantly lower risk of alcohol initiation during early follow-up periods. Recent stressful life events in Grade 6 were associated with significantly greater risk of initiating an illicit substance by Grade 8. The current findings highlight the role of stress in the initiation of illicit substance use and suggest that teacher support is associated with lower risk for very early alcohol use. Future research examining anxiety as a predictor of substance use should distinguish between subtypes of anxiety.     

Acceptance and Commitment Therapy Group Treatment for Symptoms of Borderline Personality Disorder: A Public Sector Pilot Study

A pilot study of a brief group-based Acceptance and Commitment Therapy (ACT) intervention (12 two-hour sessions) was conducted with clients of public mental health services meeting four or more criteria for borderline personality disorder (BPD). Participants were randomly assigned to receive the ACT group intervention in addition to their current treatment (ACT + TAU; N = 21) or to continue with treatment as usual alone (TAU; N = 20). There was significantly more improvement from baseline for the ACT + TAU condition than the TAU condition on the primary outcome variable—self-rated BPD symptoms. The ACT + TAU gain was both clinically and statistically significant. The ACT + TAU condition also had significantly more positive change on anxiety and hopelessness, and on the following ACT consistent process variables: psychological flexibility, emotion regulation skills, mindfulness, and fear of emotions. For all but anxiety, the improvements for the ACT + TAU condition were significant, while the TAU condition had no significant changes on any measure. Follow-up was possible for only a small number of participants. The improvements gained by the ACT + TAU participants were maintained except for fear of emotions. Anxiety continued to improve, becoming significantly different from baseline at follow-up. Examination of mediators found that psychological flexibility, emotion regulation skills and mindfulness, but not less fear of emotions, mediated BPD symptoms. Psychological flexibility and emotion regulation skills also mediated hopelessness. There is a need for a larger trial, for comparison with other established treatments for BPD, and for conducting a trial of a longer intervention. Nonetheless, this pilot study suggests that a brief group-based ACT intervention may be a valuable addition to TAU for people with BPD symptoms in the public sector.     

Authorship and responsibility in health sciences research: a review of procedures for fairly allocating authorship in multi-author studies

While there has been significant discussion in the health sciences and ethics literatures about problems associated with publication practices (e.g., ghost- and gift-authorship, conflicts of interest), there has been relatively little practical guidance developed to help researchers determine how they should fairly allocate credit for multi-authored publications. Fair allocation of credit requires that participating authors be acknowledged for their contribution and responsibilities, but it is not obvious what contributions should warrant authorship, nor who should be responsible for the quality and content of the scientific research findings presented in a publication. In this paper, we review arguments presented in the ethics and health science literatures, and the policies or guidelines proposed by learned societies and journals, in order to explore the link between author contribution and responsibility in multi-author multidisciplinary health science publications. We then critically examine the various procedures used in the field to help researchers fairly allocate authorship.     

Navigating the Dialectic: Following Ethical Rules Versus Culturally Appropriate Practice

This study investigated the association between reporting the experience of childhood abuse and perceptions of safety in current adult relationships. Data from 177 couples were collected from both clinic and community samples. Results suggest that when violence is present, people who reported being abused as a child are more likely to have lower feelings of safety in their current relationship than those who have not been abused in childhood. When no violence is present in the relationship, there is no difference in perceptions of safety between those who were and were not abused as a child. Clinical implications are discussed.     

The eACS: Attentional control in the presence of emotion

We present a questionnaire – The Emotional Attentional Control Scale (eACS) – An adaptation of the original Attentional Control Scale (ACS) that assesses the voluntary control of attention. A low score on the ACS has been associated with high levels of anxiety and depression. As the ACS items are affectively neutral, some people scoring high on the ACS may still show low levels of attentional control (AC) in more emotionally-demanding situations. We propose that the eACS, which focuses on the emotional modulation of AC, may explain additional variance in AC deficits associated with psychopathology.
