According to some authors number naming involves the mediation of semantic codes, however other authors claim that number naming could involve two routes, a semantic route and an asemantic one. Even between those that defend the existence of two routes there is some disagreement, for some of them the asemantic route is slow while according to others it could be fast. Two lexical decision experiments were conducted to examine phonological activation of Arabic digit numbers in Spanish. Arabic numbers were presented as primes and its phonology could be related to target words phonology, by sharing many phonemes with it (e.g., prime: 7, /siete/ in Spanish, target: sierra), or unrelated (e.g., prime: 2, /dos/ in Spanish, target: sierra). In experiment 1 a SOA of 50 was employed; in experiment 2 a SOA of 116. Fifty participants took part in each experiment. Results showed that target words were primed by Arabic digit numbers that shared part of the target words phonology but only when the short SOA was employed. The observed phonological priming is consistent with proposals that arabic number naming involves an early activation of phonology.
