document: Visual-word identification thresholds for the 260 fragmented words of the Snodgrass and Vanderwart pictures in Spanish Word difficulty varies from language to language ; therefore , normative data of verbal stimuli can not be imported directly from another language . We present mean identification thresholds for the 260 screen-fragmented words corresponding to the total set of Snodgrass and Vanderwart -LRB- 1980 -RRB- pictures . Individual words were fragmented in eight levels using Turbo Pascal , and the resulting program was implemented on a PC microcomputer . The words were presented individually to a group of 40 Spanish observers , using a controlled time procedure . An unspecific learning effect was found showing that performance improved due to practice with the task . Finally , of the 11 psycholinguistic variables that previous researchers have shown to affect word identification , only imagery accounted for a significant amount of variance in the threshold values
