Figure 1.

The experimental procedure for measuring speech perception with the word-to-picture matching task. The visual cue was displayed for 3000 ms, indicating the onset of the spoken target word presented over headphones. The target word was played over headphones 1500 ms after the onset of the visual cue. Thereafter, the response display was shown, which comprised four pictures, one representing the target word (here: Kopf (head)) and three representing phonologically similar distractor words (Topf (pot), Knopf (button), and Zopf (braid)).
