| Abstract: | Five experiments are reported in which a new technique for assessing the processes involved in mapping semantic representations onto name information in simple naming tasks was used. This technique, the postcue naming procedure, requires participants to name 1 of 2 potential target stimuli after they receive a relevant selection cue. Naming performance is slowed when the 2 potential targets are semantically related, relative to when they are unrelated. Effects on picture and word targets are of equal magnitude, providing these 2 types of stimulus are intermingled in the experiment. When words are presented alone, semantic interference is abolished (although evidence for lexical processing of words can be demonstrated). The effect on picture naming is also eliminated when the interfering stimulus has to be categorized rather than named. These results suggest that the locus of the interference is in the processes mapping semantic information onto names. These processes seem to be shared by pictures and words when the semantic processing of words is induced. (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
