12.1 Experiment: Lexical Competition with the Visual World Paradigm (eye-tracking)

Participants are shown a 2x2 set of images on the screen and are simultaneously presented with a spoken sentence (e.g. The birthday cake will be ready as soon as he adds the candles). There is a key word, the target (e.g. candles), that is spoken at the end of the sentence and is presented as one of the images. The other 3 images are (1) a phonological competitor (e.g. candy), (2) a semantic competitor (e.g. frosting), and (3) an unrelated filler (e.g. tape). Eye-tracking data during this task reveals lexical prediction and competition during online sentence listening.
