Figure 18:

The trial structure for Yurovsky, Yu and Smith, 2013 (adapted). On each trial, participants encountered four words and four referents, but the number of correct mappings for each word varied by type. Capital letters indicate words and lowercase letters indicate referents. Single words each had one correct mapping per trial (e.g., B - b, C - c), double words each had two correct mappings per trial (e.g., A - a1 and A - a2, F - f1 and F - f2) and noise words were not mapped to any referent (e.g., D, G). Single words and their referents are depicted in black, double words and referents in gray, and noise words in white.
