Parenting and toddler self-regulation in low-income families: What does sleep have to do with it?

Toddlerhood is a sensitive period in the development of self-regulation, a set of adaptive skills that are fundamental to mental health and partly shaped by parenting. Healthy sleep is known to be critical for self-regulation; yet, the degree to which child sleep alters interactive child–parent processes remains understudied. This study examines associations between observed parenting and toddler self-regulation, with toddler sleep as a moderator of this association. Toddlers in low-income families (N = 171) and their mothers were videotaped during free play and a self-regulation challenge task; videos were coded for mothers’ behavior and affect (free play) and toddlers’ self-regulation (challenge task). Mothers reported their child's nighttime sleep duration via questionnaire. Results revealed significant Sleep × Maternal Negative Affect and Sleep × Maternal Negative Control interactions. Children who did not experience negative parenting had good self-regulation regardless of their nighttime sleep duration. For children who did experience negative parenting, self-regulation was intact among those who obtained more nighttime sleep, but significantly poorer among children who were getting less nighttime sleep. Thus, among children who were reported to obtain less nighttime sleep, there were more robust associations between negative parenting and poorer self-regulation than among toddlers who were reported to obtain more sleep.     

Moving into tummy time,together: Touch and transitions aid parent confidence and infant development

“Back to sleep” messages can reduce prone practice for infants, with potential for motor delay and cranial deformation. Despite recommendations for “tummy time,” young infants fuss in prone, and parents report uncertainty about how to help infants tolerate prone positioning. We hypothesized that a Child'Space Method lesson, teaching proprioceptive touch and transitions to prone, would facilitate prone tolerance, parent behavioral support, and parent self-efficacy. This randomized study recruited parents (N = 37) of 2- to 5-month-old infants. On two visits, parents answered questions about infant behavior and parent experience, and played with their infant. Lesson group parents had the lesson following the first free play. One week later, lesson parents reported that infants tolerated more prone time and that parents showed more supportive behaviors in bringing infant to prone, as compared to waiting parents. Lesson parents’ efficacy, and infant behavior during play, trended in the hypothesized direction. The study demonstrated how a lesson in preparatory touch, and gradual transitions, promoted infant prone tolerance and also parent support of rolling, side-lying, and prone positioning. The lesson could be incorporated in parent education and early pediatric visits, helping infants and parents negotiate the prone challenge and setting the stage for further parent support of infant development.     

A neurodevelopmental perspective on male violence

Research is increasingly documenting a neurobiological basis to violence. This review takes a neurodevelopmental perspective on the very small group of males who grow up to become persistent violent offenders. After outlining six criteria for what constitutes a neurodevelopmental disorder, the extent to which chronic violence meets these definitional criteria is examined, covering the fields of genetics, structural and functional brain imaging, and neuropsychology. Early health risk factors for violence are then outlined, including birth complications, minor physical anomalies, prenatal smoking and alcohol exposure, poor nutrition, lead exposure, and traumatic brain injury. Persistent adult violence is argued to originate in aberrant temperamental behavior in early childhood, to have a stable developmental trajectory, and to be associated with impaired education, social, and occupational functioning. Taken together, it is argued that chronic adult violence meets criterion for being conceptualized as having neurodevelopmental origins and that an important, but not sole, source of neural maldevelopment lies in prenatal and early postnatal risk factors. This review concludes with a recognition of the sociopolitical context within which a neurodevelopmental perspective on chronic violence sits, together with directions for future research, including whether a neurodevelopmental hypothesis is best applied to reactive as opposed to proactive aggression.     

Herrnstein y la evolución del conductismo

Resumen

Resultan difíciles de identificar las suposiciones tácitas a las que Herrnstein atribuye el auge del análisis experimental de la conducta y que cree que deben exponerse y revisarse. Los supuestos que se establecen explícitamente deben revisarse constantemente, como en cualquier ciencia, pero los comentarios de Herrnstein no son particularmente útiles para ello. Los investigadores del condicionamiento operante no han descuidado las contribuciones genéticas relevantes; nunca han asegurado que los «impulsos» que utilizan en sus investigaciones constituyan una lista exhaustiva, y su. tratamiento de las clases de respuestas se aviene con los datos recientes sin necesidad de modificaciones importantes. Las intrusiones filogenéticas en la conducta ontogenética, como las que se dan en el automodelado, se ven sobrepasadas por intrusiones que se dan en la dirección contraria. La teoría del autorrefuerzo que propone Herrnstein para explicar la conducta claramente atribuible a la selección natural constituye una apelación innecesaria al. ambientalismo. La ciencia de la conducta debe referirse tanto a la filogenia como a la ontongenia, pero Herrnstein no apunta un nuevo enfoque que pueda resultar útil.     

POSTPARTUM BONDING DIFFICULTIES AND ADULT ATTACHMENT STYLES: THE MEDIATING ROLE OF POSTPARTUM DEPRESSION AND CHILDBIRTH‐RELATED PTSD

Despite decades of research demonstrating the role of adult attachment styles and early mother–infant bonding in parenting behaviors and maternal mental health, these constructs have seldom been studied together. The present study aimed to investigate the relationship between attachment styles and specific bonding difficulties of mothers. In addition, as postpartum depression and childbirth‐related posttraumatic stress symptoms have been associated with both constructs, we explored their possible mediation effect. One hundred fourteen mothers, 4 to 12 weeks’ postpartum, completed a demographic questionnaire, the Adult Attachment Style Questionnaire (M. Mikulincer, V. Florian, & A. Tolmacz, 1990), the Postpartum Bonding Questionnaire (L.F. Brockington, C. Fraser, & D. Wilson, 2006), the Modified Perinatal Posttraumatic Stress Disorder Questionnaire (J.L. Callahan, S.E. Borja, & M.T. Hynan, 2006), and the Edinburgh Postnatal Depression Scale (J.L. Cox, G. Chapman, D. Murray, & P. Jones, 1996), using an online survey system. As predicted, insecure attachment styles were associated with bonding difficulties wherein anxious/ambivalent attachment was associated with greater infant‐focused anxiety, mediated by postpartum depression but not childbirth‐related PTSD symptoms. In contrast, greater avoidant attachment style was associated with greater rejection and anger, mediated by childbirth‐related posttraumatic stress disorder (PTSD), but not depression symptoms. The current study confirmed the association of different attachment styles with bonding as well as the mediating roles of childbirth‐related PTSD and postpartum depression symptoms. Future psychological interventions may utilize such evidence to target interventions for bonding disorders in accordance with individual differences.     

Treatment Efficacy of Multiple Family Therapy for Chinese Families of Children with Attention Deficit Hyperactivity Disorder

The treatment efficacy of multiple family therapy (MFT) for Chinese families of children with attention deficit hyperactivity disorder (ADHD) has not been studied in the past. In this paper, the effect of MFT on different aspects of the lives of the parents in the experimental group (n = 61) was compared with the effect of only the psychoeducational talks on parents in the control group (n = 53). The results of a MANOVA have shown that by the time they reached the posttreatment phase, the parents who had completed the full 42 hours of the MFT program perceived their children's ADHD symptoms as being less serious and less pathological than they had originally thought compared to the parents in the control group. The effect of MFT on parent–child relationships, parenting stress, parental efficacy, hope, and perceived social support was statistically insignificant. Contributions and limitations of our study are discussed.     

Counselor Competence With Lesbian,Gay, and Bisexual Clients: Differences Among Practice Settings

Counselors from school and community practice, counseling students, and counselor educators (N= 468) participated in this study of competence to serve lesbian, gay, and bisexual (LGB) clients. Participants reported high LGB‐affirmative attitudes but lower knowledge and skills. School counselors reported significantly lower LGB competence than did counselors in other settings. Implications include the importance of graduate and postgraduate training to improve LGB knowledge and skills and the hope that LGB‐affirmative attitudes suggest receptivity toward such growth. Consejeros que trabajan en prácticas escolares y de comunidad, estudiantes de consejería y educadores de consejería (N= 468) participaron en este estudio sobre la competencia para servir a clientes lesbianas, gays y bisexuales (LGB). Los participantes comunicaron un nivel elevado de actitudes afirmativas hacia LGB, pero menores conocimientos y habilidades. Los consejeros escolares indicaron niveles de competencia en LGB significativamente menores que los consejeros en otros escenarios. Las implicaciones incluyen la importancia de la formación de estudiantes de grado y posgrado para mejorar sus conocimientos y habilidades sobre LGB y la esperanza de que las actitudes afirmativas hacia LGB sugieren receptividad hacia dicha formación.     

Variables morfológicas en el procesamiento del lenguaje

Resumen

En este artículo se revisan los principales estudios acerca del papel que pueden desempeñar las variables de tipo morfológico en la organización del léxico interno y en el acceso a la información contenida en el mismo. Más en concreto, se trata de ver hasta qué punto las relaciones derivativas entre palabras contribuyen a una simplificación del inventario mental de entradas léxicas. Para ello, se examinan las dos hipótesis alternativas fundamentales que han sido propuestas a este respecto: la hipótesis de independencia, según la cual a cada palabra le correspondería una entrada léxica distinta y la hipótesis derivacional, según la cual habría una misma entrada léxica para cada familia de palabras relacionadas morfológicamente. Los datos procedentes de las distintas áreas de la investigación psicolinguistica (comprensión, producción, adquisición y trastornos del lenguaje) parecen apoyar esta segunda hipótesis, aunque se hace notar la falta de resultados cruciales que permitan descartar la hipótesis de independencia o alguna versión modificada de la misma. Sin embargo, aun en el caso de qùe hubiera entradas léxicas distintas, sería preciso postular algún mecanismo adicional que diera cuenta de la información morfológica que utiliza el sujeto en el procesamiento de palabras.
