Impact of Family Support on Early Childhood Dysregulation in the Context of Maternal Depression

Description
The ability to regulate emotions, attention, and behavior develops early in life and impacts future academic success, social competency, behavioral problems, and psychopathology. An impairment in regulation is known as dysregulation. Past research shows that children of mothers with postpartum depression are more likely to show impairment in regulatory abilities.…

The ability to regulate emotions, attention, and behavior develops early in life and impacts future academic success, social competency, behavioral problems, and psychopathology. An impairment in regulation is known as dysregulation. Past research shows that children of mothers with postpartum depression are more likely to show impairment in regulatory abilities. There is an established link in the literature between family support and maternal depression, which in turn can impact child behavior. However, further research is needed to explore the impact of family support on early childhood dysregulation in the context of maternal depression. Using a sample of 322 Mexican-American, mother-child dyads, two models were examined. Model one hypothesized family support would buffer the effects of maternal depression on child dysregulation at 24 months. Model 2 hypothesized that family support is related to child dysregulation through its effect on maternal depression. Results showed that increased family support was related to more child dysregulation when there were high levels of maternal depression. There was no evidence to support the hypothesis that maternal depression mediated the relationship between family support and child dysregulation.

Effects of Phonotactic Probability during Early Novel Word Recognition

The goal of this study was to examine whether there is any effect of phonotactic probability during the early phases of novel word recognition. In order to determine this, I performed two experiments. In Experiment 1, 33 adult monolingual English speakers learned 24 novel word-object pairings, half of which were high English phonotactic probability words and the other half were low English phonotactic probability words. I additionally included three conditions that varied the amount of exposures to each novel word-object pairing (i.e. One Exposure Condition, Two Exposures Conditions, and Five Exposures Condition). Experiment 2 was designed to clarify results found in Experiment 1, with improved randomization and fewer conditions (i.e. One Exposure Condition and Five Exposures Condition). The findings from both experiments were statistically significant in accuracy for Training condition, but not statistically significant for phonotactic probability nor for an interaction between phonotactic probability and Training condition. Although participants demonstrated learning across conditions there is no indication of a relationship between high and low phonotactic probability and novel word recognition. Collectively, these findings suggest that future studies will be necessary to determine if there is indeed an effect of phonotactic probability on early novel word recognition.

Does synchrony between a parent and child provide risk or resilience for a child's symptoms of psychopathology?

It is essential to identify different causes of this to understand better how to prevent psychopathology in children.

The number of children currently experiencing a psychopathological disorder is growing quickly. It is essential to identify different causes of this to understand better how to prevent psychopathology in children. Prior research has shown that different emotion dynamics between the parent and child, like rigidity, flexibility, or synchrony, have been found to be associated with psychopathology. Synchrony or the matching of positive emotions in a dyad has been found to be protective against symptoms of psychopathology for children. In addition, flexibility, or the number of emotion transitions between a dyad, has also been shown to be protective against symptoms of psychopathology, although rigidity or fewer emotion transitions in a dyad has been predictive of psychopathology. However, this research has been almost entirely focused on infants and toddlers as well as adolescents, with little research being done on synchrony, rigidity, and flexibility in middle childhood. This study aimed to identify whether synchrony, rigidity, and flexibility are predictive or protective of internalizing, externalizing, and ADHD symptoms of psychopathology in middle childhood. Data was collected from a sample of 762 ethnically diverse children from the Arizona Twin Project that were assessed at ages 9 (Mage=9.71, SD=.93) and 11 (Mage=11.65, SD=1.04). Children and their parents were examined when the child was 9 during a video-recorded discussion task to determine rigidity, flexibility, and synchrony that was coded by iMotion Affectiva. Internalizing, externalizing, and ADHD symptoms of psychopathology were measured at ages 9 and 11 both through parent-report and child report. Results found that during a conflict-based discussion, synchrony and negative co-regulation between the parent and child were protective against internalizing, externalizing, and ADHD symptoms of psychopathology both concurrently and longitudinally. Rigidity and flexibility between the parent and child were not found to be associated with psychopathology. These findings can help inform future parenting programs or influence parent child interactions by teaching the importance of using positive emotions during negative conversations with parents.
