The relation of 8- to 10-year-olds' teacher-reported dispositional sympathy to regulation and emotionality was examined with a longitudinal sample. In general, sympathy was correlated with adults' reports of regulation and low negative emotionality contemporaneously and, to some degree, 2 and 4 years prior. General emotional intensity interacted with some aspects of regulation in predicting sympathy; for example, attention focusing predicted sympathy but only for children low in general emotional intensity. In general, the pattern of correlations changed little from age 6-8 to age 8-10 years, although parent-reported negative emotionality was more highly negatively related to sympathy at the older age. Dispositional sympathy was associated with verbal or physiological markers of sympathy in a laboratory setting.
