Temperament, effortful control, and problem behaviors at 4.5 years were assessed in 72 children classified as exuberant, inhibited, and low-reactive as 2-year-olds. Exuberant toddlers were more positive, socially responsive to novel persons, less shy, and rated as having more problem behaviors including externalizing and internalizing behaviors, than other children as preschoolers. Two forms of effortful control, the ability to delay a response and the ability to produce a subdominant response, were associated with fewer externalizing behaviors, while expressing more negative affect (relative to positive/neutral affect) when disappointed was related to more internalizing behaviors. Interaction effects implicated high levels of unregulated emotion during disappointment as a risk factor for problem behaviors in exuberant children.

One construct that has received considerable research attention for its theoretical and empirical links to these outcomes is temperament. In the present study we examined developmental outcomes, specifically externalizing and internalizing behavior, of children varying on the temperament dimensions of approach and inhibition. This research is based on the theoretical model which proposes that temperament may have a critical role in the development of psychopathological conditions (Frick & Morris, 2004;Rothbart, Posner, & Hershey, 1995). Likewise, our study is informed by the developmental psychopathology framework (Cicchetti & Cohen, 1998) which emphasizes the application of normative development to understanding atypical populations and the study of individual developmental pathways as essential to identifying those most likely to develop maladaptive behaviors.Several pathways by which temperament may be related to high-risk conditions or psychopathology have been proposed (Rothbart et al., 1995). Psychopathology, for example, may directly map onto a temperamental extreme, as when an infant who has difficulty Please send correspondence to: 105 White Building, The Pennsylvania State University, University Park, PA 16803, 814-865-2666 (office), 814-865-4417 (fax), TVR@PSU.EDU.

Temperament may also contribute to psychopathology by providing a context that interacts with other factors to increase the probability of a disorder. A tendency to be easily frustrated, for example, may create difficulties interacting with peers, which in turn may lead to heightened aggression. On the positive side, temperament may also act as a buffer to conditions that put a child at risk, as in the example of a chil...
