Children's conversations were investigated to determine whether a theo
ry of motivated behavior was revealed that explains the causes which p
roduce an affect, the object of the affect, its behavioral and physiol
ogical signs, and the consequences of experiencing the affect. Also ex
amined was whether discussions varied for two affect categories: prefe
rences and emotions. One analysis was based on the conversations of 39
children ages 4.5 to 5 years old who represented diverse racial and s
ocial class groups. Children were taped talking to peers, family membe
rs, and teachers in 10 settings. Causes and consequences were more lik
ely to be supplied for emotions than preferences. A second analysis wa
s based on longitudinal data collected on four 2-year-olds. These chil
dren and their parents also provided more information about emotions t
han preferences. The semantic and pragmatic bases of the distinction b
etween preferences and emotions provided a framework for understanding
the two ways of talking about affects.
