Previous work has shown that sentences with actional verbs (e.g., to h
it) are better understood by children than sentences with nonactional
verbs (e.g., to see). This effect is accounted for in contrasted ways
in the literature. These explanations are analyzed and found wanting b
oth theoretically and empirically. An alternative suggestion is made.
It is based on new data as well as on a reanalysis of previously publi
shed ones. Accordingly, actional verbs favor the construction of menta
l images that serve as supports for the operations involved in process
ing sentences.
