Recognition Time Measured by Verbal Reaction to Figures and Words
Paul Fraisse · Perceptual and Motor Skills · 1960
Five Ss were required to recognise as quickly as possible four words (square, triangle, hexagon, octagon) and the four corresponding figures. Ss were acquainted with the eight stimuli, for the present experiment was preceded by one in which tachistoscopic perceptual thresholds were obtained. The stimuli were presented in random order for an unlimited time and the whole list was shown five times. Verbal reaction time was recorded by means of a vocal key. S's median for each stimulus was calculated, and then the mean of medians for words and figures. Results are given in .O1 sec.
