Differential effects of number of letters on word and nonword naming latency: revisited.

Previous research conducted in English has shown that number of letters has an impact on RTs in a naming task (Weekes, 1997). The aim of the current study is to explore whether similar effects would be found in Turkish characterized by unique transparent relationship between print and sound. Previous research in Turkish has shown that readers can adopt a lexical strategy in reading (Raman, Baluch & Besner, 2004) and a robust frequency effect (Raman, Baluch & Sneddon, 1996). The results from Turkish have been explained within the dual-route model of reading (Coltheart and colleagues 1978; 2003) such that a lexical route is assumed to be used primarily to read all words in Turkish (Raman, et al 1996). Participants were asked to read words and nonwords manipulated on length and frequency in two naming tasks and data were subjected to regression analyses. The findings are discussed within the dual-route model of reading.
