The discovery of a miniature linguistic system: Function words and comprehension of an unfamiliar language

Two experiments investigated two complementary hypotheses: (a) The presence of semantically unimportant function words in sentences will not slow down the way subjects, unfamiliar with the language, extract the meaning of those sentences, provided suprasegmental cues are present, and conversely (b) the omission of such function words—as in native speakers' simplified speech to nonnative speakers—will not necessarily facilitate the task of meaning extraction, contrary to popular belief. In Experiment I, Dutch adult subjects were exposed to sentences in a miniature artificial language (MAL). In Experiment II, Greek adult subjects were exposed to sentences in an unfamiliar natural language (Dutch). In both experiments, the sentences contained eight words constituting a miniature linguistic system (mls), a system that subjects discovered through an audiovisual, concept-indentification task. The rate by which subjects performed this task was investigated as a function of two linguistic variables: (a) the presence or absence of semantically unimportant function words, and (b) the presence or absence of suprasegmental cues, in the input sentences, respectively. Results from both experiments confirmed the hypotheses (p<.001) The findings are discussed with reference to the linguistic versus cognitive simplicity issue, and to the comprehension versus production issue in language acquisition research. The methodological potential of the experimental paradigm for psycholinguistic research is also discussed.This paper forms part of a doctorate research project concerned with the comprehensibility of foreigner talk, and was supported by the Foundation for Linguistic Research, which is funded by the Netherlands Organization for Scientific Research, NWO.
