A cornerstone of children’s socio-cognitive development is understanding that others can have knowledge, thoughts, and perceptions that differ from one’s own. Preschool-aged children often have difficulty with this kind of social understanding, i.e., they lack an explicit theory of mind. The goal of this dissertation was to examine the role

A cornerstone of children’s socio-cognitive development is understanding that others can have knowledge, thoughts, and perceptions that differ from one’s own. Preschool-aged children often have difficulty with this kind of social understanding, i.e., they lack an explicit theory of mind. The goal of this dissertation was to examine the role mental state language as a developmental mechanism of children’s early understanding of their own mental states (i.e., their introspective ability). Specifically, it was hypothesized that (1) parents’ ability to recognize and appropriately label their children’s mental states and (2) children’s linguistic ability to distinguish between their mental states shapes the development of children’s introspective ability. An initial prediction of the first hypothesis is that parents should recognized differences in the development of children’s self- and other-understanding in order to better help their children’s introspective development. In support of this prediction, parents (N = 400, Mage = 58 months, Range = 28-93 months) reported that children’s understanding of their own knowledge was greater than children’s understanding of others’ knowledge. A prediction of the second hypothesis is that children’s linguistic ability to distinguish between and appropriately label their own mental states should determine their ability to make fined grained judgments of mental states like certainty. In support of this prediction, children’s (N = 197, Mage = 56 months, Range = 36-82 months) ability to distinguish between their own knowledge and ignorance states was associated children’s ability to engage in uncertainty monitoring. Together, these findings provide support for the association between children’s linguistic environment and ability and their introspective development.

Description
Fast mapping is the initial link infants make between a word and its referent, and it is crucial to later processes of learning the meanings of words. Despite the importance of fast mapping, previous research has suggested that fast mapping is fragile, with infants being unable to retain words learned

Fast mapping is the initial link infants make between a word and its referent, and it is crucial to later processes of learning the meanings of words. Despite the importance of fast mapping, previous research has suggested that fast mapping is fragile, with infants being unable to retain words learned through fast mapping longer than five minutes. The current study tested the robustness of fast mapping by imposing task irrelevant interruptions on a fast mapping task. Forty-seven infants (14.7 \u2014 17.4 months old) were assigned to a No Interruption condition, a Posture Interruption condition, or a Visual Interruption condition, and they performed a fast mapping task in which a novel object was named in one trial. Videos of the infants were coded for accuracy of fast mapping and for attentional behaviors (looking behavior) during the task. We found that infants did not learn novel word-object pairings when interrupted, demonstrating that infants' fast mapping abilities are easily disrupted. Overall, there was no evidence that looking behaviors were affected by interruptions, or that they were correlated with accuracy. These findings suggest that fast mapping is fragile in young infants, and further research is required to determine the mechanisms for infant learning, and how infants transition from fast to slow mapping processes.

In past decades, adverse childhood experiences (ACEs) rapidly gained attentionas a public health crisis due to dose-response relationships with a range of health and social problems, and early mortality.

In past decades, adverse childhood experiences (ACEs) rapidly gained attentionas a public health crisis due to dose-response relationships with a range of health and social problems, and early mortality. Converging studies show that ACEs are a pandemic in the general population of the United States—even in middle to upper-middle class families that are considered to be ‘better off’. There have been collaborative efforts in public health to target root-causes of childhood adversity and increase resilient adaptation in individuals and families at risk. Due to the importance of fostering positive adaptation in the midst of adversity, this dissertation sought to examine both vulnerability and protective factors in children’s proximal ecology—e.g., parents and caring adults at school. A population-based study in this dissertation revealed that parents’ emotional well-being, measured as negative feelings toward parenting, greatly influences developing children, so as support and resources for parenting. The presence of caring adults as a protective factor in teens with highly competitive settings—a newly identified at-risk group due to high pressure to achieve and internalizing/externalizing problems. Lastly, this dissertation discusses conceptual and methodological limitations in current ways of measuring ACEs and provide future directions for research, practice, and policy. Suggestions include frequent assessments on reaching consensus on how to define ACEs, expanding the concept of ACEs, considering the duration, timing, and severity of the event. Healthcare professionals have important roles in public health; they incorporate frequent assessments on parents’ emotional wellbeing and needs for parenting as a part of care. Ongoing support from multiple disciplines is necessary to reduce the impact of ACEs and strengthen resilience development of children and families.
