Figure 3.

Illustration of trial event sequence. (1) Trial begins with the appearance of two images on the screen, which appear in silence for 2000 ms before the (2) appearance of a central stimulus. This central stimulus remains on screen until gaze is registered on the central image for 100 ms. (3) The central stimulus then disappears and the target label is spoken (e.g. Juice! That’s cool!). The images remain on the screen for 4000 ms after the onset of the spoken target label. Note that trial is initiated by gaze towards a central pre-trial attention getter (not pictured here).
