Visual recognition thresholds and dimensions of word meaning

Abstract

Tachistoscopic recognition thresholds were obtained for nouns with high or low values on one dimension of meaning while two others were controlled. Frequency, imagery concreteness (I), and meaningfulness (m), were varied in different lists in one experiment, frequency and m in a second, and m alone in a third. Ratings of familiarity were also obtained to supplement frequency as a measure of familiarity. The results showed that ease of visual recognition was most strongly related to frequency and familiarity. Imagery was unrelated to thresholds when familiarity and m were controlled. Meaningfulness showed a small but consistent positive relation to ease of recognition even with the other variables held constant. Except for the puzzling effect of m, the results are consistent with the view that perceptual recognition is primarily dependent upon the familiarity of the target stimulus and not upon associative processes evoked by it. © 1970 Psychonomic Society, Inc.
