Adult learners have persistent difficulty processing second language (L2) inflectional morphology. We investigate associative learning explanations that involve the blocking of later experienced cues by earlier learned ones in the first language (L1; i.e., transfer) and the L2 (i.e., proficiency). Sagarra (2008) and Ellis and Sagarra (2010b) found…

The current study investigates the limited attainment of adult language acquisition in terms of an associative learning phenomenon whereby earlier learned cues attentionally block those that are experienced later. Short- and long-term blocking are demonstrated in experimental investigations of learned attention in the acquisition of temporal…
