N2 - Direct measurements of effects of spatial separation between stimuli in whole reportfrom brief visual displays are reported. The stimuli were presented on the periphery ofan imaginary circle centered on fixation. In Experiment 1, each display showed 2capital letters (letter height = 1.3°, width = 0.9°, eccentricity = 5.5°). The proportionof correctly reported letters was a strictly increasing, decelerating function of thespatial separation between the letters for center-to-center separations ranging fromless than 2° to more than 10° of visual angle. Experiment 2 yielded similar resultswith triples of letters. Experiment 3 showed that accuracy increased with spatialseparation for report of 2 short words, and Experiment 4 showed the same result forwords presented upside-down. The results are explained by a model of lateral masking(crowding) based on competitive interactions within receptive fields of corticalneurons.
