Name-picture verification as a control measure for object naming: Data from British English speakers

The name-picture verification task is often used to assess the difficulty of prelexical processes (object recognition and semantic access) during picture naming. However, whether to use responses from word-picture match or from mismatch trials to index the difficulty of pre-lexical processes is debated. Levelt (2002) argued for the use of mismatch trials because on match trials the printed object name might facilitate picture recognition. However, in a study with speakers of Spanish Stadthagen-Gonzalez et al. (2009) showed that visual and conceptual properties of objects only correlated with the latencies of match responses but not with those of mismatch responses and therefore advocated the use of match responses. The present study aimed to replicate Stadthagen- Gonzalez et al. (2009) findings using native British English speakers and English norms for non-lexical and lexical variables. We replicated the finding that non-lexical variables affected the speed of match, but not mismatch responses. However, in addition, we found that lexical variables also affected the speed of match responses, which means that these latencies need to be interpreted with caution. In other words, neither match nor mismatch responses seem ideally suited to assess the difficulty of pre-lexical processes in picture naming. Levelt, W. J. M. (2002).
