Three experiments examined the bilateral field advantage (BFA) on both verbal and nonverbal matching tasks. The goal of the experiments was to determine which conditions would maximize the size and reliability of the BFA, and thus enhance its value as a possible diagnostic tool to assess callosal dysfunction. In Experiment 1, 27 right-handed college students performed two matching tasks (order of tasks varied across subjects; dots-letters, letters-dots, or letter and dot trials randomly interleaved). Results revealed a verbal BFA in all task order conditions (p<.01), but a significant nonverbal BFA only in the interleaved condition (p<.01). Experiments 2 and 3 reproduced the interleaved condition with different parameters. In both experiments the verbal BFA was significant (p<.01), but nonverbal BFA was significant only when four-dot patterns were used (p<.05). Results suggest the interleaved presentation of verbal and nonverbal stimuli is a reliable method of measuring the BFA.
