Activation of the representations of the two languages in bilingual memory has been shown to affect recognition during initial word comprehension (e.g., Dijkstra & Van Heuven, 2002). This study investigated whether the activation of semantic (i.e., meaning) and lexical (i.e., form) representations of words in a bilingual's two languages affects word recognition after the first stages of word comprehension. False recognition of words in one language that were similar in meaning and/or form to words studied in the other language was an indication of these effects. This study further investigated whether false recognition based on meaning and/or form is modulated by bilingual language proficiency.
