aspect in English

[Ludovica Serratrice]

Dear colleagues,

is anyone aware of studies that have looked at English-speaking
children's sensitivity to the aspectual distinction between present
tense forms [-progressive] and -ing forms [+progressive]? I would
like to know whether there is any evidence that monolingual
English-speaking children would use a present tense form such as
"she swims", instead of "she's swimming", for a [+progressive]
event. Thanks in advance for any help.
