In this study, the relationship between short-term emotion expressions and
dimensional ratings of internalizing and externalizing symptomatology was e
xamined. Short-term emotions, defined as facial or vocal displays of emotio
n generally lasting less than 10 seconds and elicited by a specific and pro
ximal event, were observed during recess in 71 children from diverse socioe
conomic backgrounds, who were between 4 and 8 years old. Internalizing and
externalizing symptomatology was assessed through parent and teacher questi
onnaire. Sociometric ratings were obtained from peers on children's anger a
nd aggression. It was hypothesized following Tomkins (1979) and others that
one affect becomes predominant in the emotional experience of the individu
al. Different operationalizations of this concept were examined. Using regr
ession analyses, externalizing symptomatology was found to be predicted by
higher levels of anger, lower levels of happiness, and lower levels of sadn
ess. Internalizing symptomatology was found to be predicted by higher level
s of sadness and lower levels of anger. It was concluded on the basis of th
ese data that the relationship between short-term emotion and internalizing
and externalizing psychopathology is best understood as the balance betwee
n different short-term emotions. Results are discussed in the context of th
eories of emotion and their functions.
