abstract: The purpose of this study was to examine the longitudinal relations of maternal behaviors, children`s temperamental negative emotionality, and children`s emotion perception processes, including emotion perception accuracy (EPA) and emotion perception bias (EPB), to children`s conduct disorder symptoms in a normative sample. Separate structural equation models were conducted to assess whether parenting or children`s proneness to negative emotions at 24-30 (T2), 36-42 (T3) and 48-54 (T4) months predicted children`s EPA and EPB over time, and whether T3 and T4 children`s emotion perception processes were predictive of children`s conduct disorder at 72 months of age (T5). None of the hypothesized longitudinal relations was supported; however, other noteworthy results were observed. T3 children`s proneness to negative emotions was positively related to children`s concurrent bias toward anger. The latent constructs of negative parenting, children`s proneness to negative emotions, and the observed measure of children`s emotion perception accuracy showed stability over time, whereas the observed measures of children`s bias toward understanding distinct negative emotions were unrelated across time. In addition, children`s expressive language was predicted by children`s earlier emotion perception accuracy, which emphasized the importance of improving children`s emotion understanding skills during early years. Furthermore, the previously established negative relation between EPA and EPB variables was only partially supported. Findings regarding the relations between parenting, children`s negative emotionality and emotion perception processes are discussed from a developmental perspective. / Dissertation/Thesis / M.S.
