Attention to Threat as a Predictor of Shyness in the Context of Internalizing and Externalizing Behavior

The duration of children's attention to putative threat has been documented as a consistent predictor of later anxiety in inhibited children across childhood (Fox, New Directions for Child and Adolescent Development, 127, 2010, 33; Pérez‐Edgar & Fox, Child and Adolescent Psychiatric Clinics of North America, 14, 2005, 681). However, attention to threat has not been broadly examined within existing behavioral contexts and has seldom been studied in very early childhood. Whereas toddlers with high levels of internalizing behavior may view fear‐inducing stimuli as a threat, toddlers with high levels of externalizing behavior may demonstrate attention out of interest or sensation seeking. Thus, attention to threat was expected to predict increased toddler shyness in the context of either high internalizing problems or low externalizing behavior. We examined 117 twenty‐four‐month‐old toddlers to determine whether attention to threat interacted with internalizing and externalizing behavior at 24 months of age to predict toddler shyness one year later. Results indicated that attention to threat predicted toddlers' lower shyness at 36 months when toddlers’ externalizing behavior at age 24 months were high, but there was no significant interaction between toddlers’ internalizing behavior and their attention to threat in predicting later shyness. These results expand our understanding of the contexts in which attention to threat in early childhood is a viable predictor of later shyness.     

Complex Interrelations of Trait Vulnerabilities in Mothers and their Infants

Despite the developmental and clinical relevance of this area of inquiry, no studies have examined the interrelations of trait vulnerabilities in the affective, behavioral, and interpersonal domains between mothers and their infants. Thus, this study examined the interrelations of three trait vulnerabilities (i.e., negative affective intensity, impulsivity, and insecure attachment) between mothers and their 12‐ to 23‐month‐old infants, focusing in particular on the unique and interactive influence of these maternal trait vulnerabilities on the expression of and precursors to these traits in their infants. Mother–infant dyads (N = 101) completed several laboratory procedures, and mothers reported on their own and their infants' expressions of the trait vulnerabilities of interest. Findings from this study provide preliminary evidence for intergenerational relations between these traits and suggest that it is the confluence of trait vulnerabilities in mothers that relates to the early expression of some of these traits in infants.     

Mother–Toddler Cortisol Synchrony Moderates Risk of Early Internalizing Symptoms

Cortisol synchrony is the degree to which mother–toddler cortisol levels are mutually regulated within a dyad. Synchrony's impact on toddler development is not well understood, so this study investigated how synchronous cortisol levels (reactivity and total concentration) in mother–toddler dyads moderate the association between risk factors (i.e., maternal worry, toddler inhibition) and early internalizing symptoms. Seventy mothers and their 2‐year‐old toddlers provided interpretable saliva samples. Behavioral observations were made to assess the toddler's temperament at age 2, and mothers reported on their toddler's internalizing symptoms when toddlers were 2 and 3 years old. Results suggest that mother–toddler synchrony in total cortisol concentration moderates the relation between risk factors and internalizing symptoms. Specifically, toddler inhibition and maternal worry were less associated with concurrent toddler internalizing symptoms when dyads demonstrated greater cortisol synchrony in total concentration. Further, synchrony in total cortisol levels marginally moderated the association between toddler inhibition and future internalizing symptoms, such that inhibited toddlers were less likely to demonstrate internalizing symptoms at age 3 when dyads demonstrated more cortisol synchrony. This suggests that cortisol synchrony may serve as an advantageous context that reduces the risk of developing of internalizing symptoms and augments the field's understanding of the implications of shared physiological responses within mother–toddler dyads.     

The Association Between Infants’ Attention Control and Social Inhibition is Moderated by Genetic and Environmental Risk for Anxiety

Infant social inhibition is associated with increased risk for anxiety later in life. Although both genetic and environmental factors are associated with anxiety, little empirical work has addressed how developing regulatory abilities work with genetic and environmental risk to exacerbate or mitigate problem behaviors. The current study was aimed at addressing this gap in research by investigating an early emerging regulatory behavior, attention control, in association with genetic and environmental risk for anxiety. Participants included 9‐month‐old adopted infants, their birth mothers, and adoptive parents (N = 361). Lifetime diagnosis of birth mother social phobia was obtained using structured interviews. Adoptive parents completed self‐report measures of anxiety symptoms. Infant social inhibition and attention control were coded during a stranger interaction and a barrier task, respectively. Neither adoptive nor birth parent anxiety was directly associated with social inhibition. The association of attention control with social inhibition in infants was moderated by birth and adoptive parent anxiety symptoms. When infants of birth mothers with social phobia were raised by adoptive parents with high self‐reported anxiety symptoms, greater attention control was associated with greater social inhibition. However, when raised by adoptive parents with low self‐reported anxiety, greater attention control was associated with less social inhibition.     

Maternal neural reactivity during pregnancy predicts infant temperament

Maternal biological systems impact infant temperament as early as the prenatal period, though the mechanisms of this association are unknown. Using a prospective, longitudinal design, we found that maternal (N = 89) amplitudes of the late positive potential (LPP) in response to negative stimuli during the second, but not the third, trimester of pregnancy predicted observed and physiological indices of temperamental reactivity in infants at age 4 months. Maternal LPP was positively associated with observed infant fear and negatively associated with frontal EEG asymmetry and cortisol reactivity in infants at age 4 months. Results identify a putative mechanism, early in pregnancy, for the intergenerational transmission of emotional reactivity from mother to infant.     

Gender Moderates the Progression from Fearful Temperament to Social Withdrawal through Protective Parenting

Child gender may exert its influence on development, not as a main effect, but as a moderator among predictors and outcomes. We examined this notion in relations among toddler fearful temperament, maternal protective parenting, maternal accuracy in predicting toddler distress to novelty, and child social withdrawal. In two multi‐method, longitudinal studies of toddlers (24 months at Time 1; Ns = 93 and 117, respectively) and their mothers, few main effect gender differences occurred. Moderation existed in both studies: only for highly accurate mothers of boys, fearful temperament related to protective parenting, which then predicted later social withdrawal. Thus, studying only main‐effect gender differences may obscure important differences in how boys and girls develop from fearful temperament to later social withdrawal.     

Caregiver Protective Behavior,Toddler Fear and Sadness,and Toddler Cortisol Reactivity in Novel Contexts

Previous research has shown that caregiver protective behavior may exacerbate toddler distress in specific contexts. This study sought to extend this work to examine associations between these variables and toddler cortisol reactivity. Ninety‐three 24‐month‐old toddlers were observed across six novel contexts designed to elicit distress. Toddlers were asked to give saliva samples at the beginning and end of the laboratory procedure. Toddler sadness, toddler fear and caregiver protective behavior were coded. Results indicate that caregiver protective behavior accounted for the association between toddler sadness and cortisol reactivity where higher levels of protective behavior were associated with higher cortisol reactivity. This study showed that caregiver protective behavior, which functions to prevent a child from interacting with a novel stimulus, is an important mechanism to consider when understanding toddler stress responses during novel contexts.     

Child Sexual Abuse and the Family Court

This paper examines judicial decision-making in the Family Court in custody and access disputes where allegations of child sexual abuse have been made. In seven cases examined judges took a sceptical view of such allegations and most commonly granted access in spite of strong evidence of abuse. The interpretation of the ‘best interests of the child’ often favoured continuing contact with both parents, and judges rarely denied access outright. Supervised access, the most common outcome, represents a compromise between familial ideology and child protection.     

Maternal anxiety and toddler inhibited temperament predict maternal socialization of worry

Parent emotion socialization refers to the process by which parents impart their values and beliefs about emotional expressivity to their children. Parent emotion socialization requires attention as a construct that develops in its own right. The socialization of child worry, in particular, has implications for children’s typical socioemotional development, as well as their maladaptive development toward anxiety outcomes. Existing theories on emotion socialization, anxiety, and parent–child relationships guided our investigation of both maternal anxiety and toddler inhibited temperament as predictors of change in mothers’ unsupportive (i.e., distress, punitive, and minimizing) responses to toddler worry across 1 year of toddlerhood. Participants included 139 mother–toddler dyads. Mothers reported on their own anxiety and their emotion socialization responses to toddler worry. We assessed toddler inhibited temperament through a mother‐report survey of shyness and observational coding of dysregulated fear. Maternal anxiety but not child inhibited temperament predicted distress reactions and punitive responses, whereas maternal anxiety and toddler dysregulated fear both uniquely predicted minimizing responses. These results support the continued investigation of worry socialization as a developmental outcome of both parent and child characteristics.
