Visual-word Identification Thresholds for the 260 Fragmented Words of the Snodgrass and Vanderwart Pictures in Spanish

Behav Res Methods Instrum Comput. 2002 May;34(2):276-85. doi: 10.3758/bf03195455.

Abstract

Word difficulty varies from language to language; therefore, normative data of verbal stimuli cannot 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 (1980) 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.
