The repetition blindness effect (RB) occurs when individuals are unable to recall a repeated word relative to a nonrepeated word in a sentence or string of words presented in a rapid serial visual presentation task. This effect was explored across languages (English and Spanish) in an attempt to provide evidence for RB at a conceptual level using noncognate translation equivalents (e.g., nephew-sabrina). In the first experiment, RB was found when a word was repeated in an English sentence but not when the two repetitions were in different languages. In the second experiment, RB was found for identical repetitions in Spanish and in English using word lists. However, the crosslanguage condition produced significant facilitation in recall, suggesting that although conceptual processing had taken place, semantic overlap was not sufficient to produce RB.The results confirm Kanwisher's (1987) token individuation hypothesis in the case of translation equivalents.Repetition blindness (RB) (Kanwisher, 1986(Kanwisher, , 1987 refers to the inability to recall a repeated word in a rapid serial visual presentation (RSVP) task. For example, for the sentence, "She ate salad andfish even though the fish was raw," readers show poor recall of the second presentation of the word fish relative to recall performance for the following control: "She ate salad and seafood even though thefish was raw." The effect occurs in the repeated case even though the omission of the second word makes the sentence ungrammatical.RB is a robust finding and has been reported now by a number of researchers using a variety of different paradigms (e.g., Hochhaus & Marohn, 1991;Humphreys, Besner, & Quinlan, 1988;Mozer, 1989). The RB effect has been found when both words differ in case (Kanwisher, 1987;Marohn & Hochhaus, 1988) and with as many as three intervening words present between the first and the second repetition. Presentation rates of approximately 8 words per second typically yield this effect, and lengthening presentation rate diminishes blindness (Kanwisher, 1987;Park & Kanwisher, 1994).
