Fig 7. Eye-tracking results from Experiment 2 compared with those from Experiment 1.

Note that in Experiment 1, vowel-initial targets were presented with an epenthetic glottal stop, and in Experiment 2, they were presented without such a stop. For glottal stop-initial targets, the signals in the two experiments were identical, but participants might have learned that a glottal stop was unlikely to be epenthetic, which would rule out vowel-initial targets from the onset-competitors.
