Bilingual Lexical Representation: The Status of Spanish-English Cognates

Abstract

Two experiments were conducted to determine the functional status of cognates. Two hypotheses were considered. According to the first hypothesis, language is a critical feature governing lexical organization, and cognates may therefore be equated with morphologically unrelated translations. According to a second hypothesis, however, language is not a critical feature governing lexical organization. Instead, the boundaries between perceptual categories are determined by morphological considerations, and cognates may therefore be equated with intra-lingual variations such as inflections and derivations. If the first hypothesis is correct, cognate performance should follow that observed for translations, but if the second hypothesis is correct, cognate performance should follow that observed for inflections and derivations. The experiments used different procedures in order to discount taskspecific explanations. The first experiment involved repetition priming in a lexical decision task, and emphasis was placed on relative priming; that is, on the amount of facilitation which occurs when, for example, OBEDIENCIA primes OBEDIENCE, expressed as a fraction of the amount of facilitation that occurs when the same word is presented on each occasion (i.e., when OBEDIENCE is used to prime OBEDIENCE). The second experiment tested memory for language. Four types of cognates were tested. These were: orthographically identical cognates, regular cognates with cion/tion substitution, regular cognates with dad/ty substitution, and irregularly derived cognates. The results were unequivocal. The priming values observed previously for cognates were qualitatively and quantitatively similar to those observed for inflections and derivations, and this classification was confirmed in the second experiment, involving memory for language. The results are consistent with the general proposition that morphology rather than language governs the boundaries between perceptual categories, and a number of specific explanations are reviewed.
