The standard disambiguation
condition replicated previous findings. All age groups selected the unfamiliar objects as referents
for the novel terms. The second condition (Pragmatic Cue task) presented a very different picture, a
clear developmental shift in object choice; whereas 3-year-olds continued to pick the novel object
and disregard the pragmatic cue, 5-year-olds selected the familiar object as referent for the novel
word and, thus, no longer demonstrated a mutual exclusivity bias.
