The bilateral field advantage in a sequential face-name matching task with famous and nonfamous faces.
The authors examined the bilateral field advantage (BFA) using a sequential name-face (Experiment 1) or face-name (Experiment 2) matching task with both famous and nonfamous stimuli. In both experiments, the first stimulus (name in Experiment 1, face in experiment 2) was followed by a delay of 1,500 ms. The second stimulus (face in Experiment 1, name in Experiment 2) was then presented during a speeded response interval. Experiment 1 indicated a BFA for famous faces, but not for recently familiarized nonfamous faces. Experiment 2 indicated a BFA for names regardless of familiarity level. These results are compatible with prior findings of a BFA for meaningful stimuli as opposed to nonmeaningful ones, but only if previously unknown personal names are considered meaningful while previously unknown faces are not. These findings suggest that personal names are processed by bilateral neural networks whether they are previously known or not, whereas this is not the case for faces. Our findings have additional implications for working memory-based theories of why the BFA arises, and for the time course of meaningful association formation.
