Resumen:	This paper examines the relationship between perceived similarity between first language (L1) and second language (L2) vowels and discrimination of L2 vowel pairs in light of L2 speech models'predictions on L2 vowel discrimination. The study also explores the role of word status (real vs. nonsense word) in L2 vowel discrimination. Fortyfour Spanish learners of English performed a perceptual assimilation task and two L2 vowel discrimination tasks. The discrimination tasks presented the members of each pair in the two possible orders (e. g. , /i/-/ɪ/, /ɪ/-/i/), and stimuli were embedded in real and nonsense words. Results showed that discrimination accuracy was not always explained by crosslinguistic mapping relations as proposed by L2 speech models such as the Perceptual Assimilation Model-L2. Further, directional asymmetries emerged, mirroring previous findings in infant and adult perception. Finally, discrimination accuracy was greater in real words than in non-sense words, underscoring the influence of lexical categories in L2 perception.
