We tested children and adults' comprehension of complex sentences like
"Before she takes a hot bath, she draws a picture". Sentences with four
different connectives (after, before, because, if) in two clause orders
(main-subordinate, subordinate-main) were tested with a forced-choice
picture sequence task. Results support a semantic account: Children
performed better with sentences in iconic clause order, where the order of
events in the sentence reflects the order of events in the real world, and
with before-sentences. Responses were slower with because- and
if-sentences. Working memory did not play a role. Adults performed at
ceiling and were faster with before-sentences.
