This special issue brings together a set of four papers devoted to the experimental study of sentence processing by bilinguals in their second language. The basic finding reported in this research is that, in many cases, learners transfer their LI sentence processing strategies onto sentence processing in L2. Moreover, the influence of this transfer can be detected in weakened form even in fluent bilinguals who have spoken L2 for many years. In effect, these studies report on a kind of comprehension analog to “foreign accent” that first came to light during work on sentence comprehension within the framework of the Competition Model of Bates and MacWhinney (1982).

The present study investigates the interaction of syntax, semantics, and pragmatics from the perspective of functional constraints on sentence processing. The functionalist model of Bates and Mac-Whinney (1981a, 1987) is taken as a basis for investigating subjects' reactions to sentences in which word order, topic, and animacy are varied. Subjects were native speakers of Italian, a language which is sensitive to semantics for interpretation and English, a language which is sensitive to syntax for interpretation (Bates, McNew, MacWhinney, Devescovi, & Smith, 1982). The two native speaker groups were further subdivided in terms of second versus foreign language learners. This study focusses on the question of how learners move from one organizational system to another. It is argued that the ways in which L2 learners are able to determine the strength of dominant factors provides insights not only into the processes involved in L2 acquisition but also into the relative strength of components crosslinguistically and the strength of boundaries between linguistic and extra-linguistic information. The results suggest that in moving from a semantic-dominant language to a syntactic-dominant one, learners first become aware of the importance of the concept of word order in a second language before being able to determine the specifics of word order in that language. On the other hand, moving in the other direction (from syntactic to semantic dominance) seems to come about with greater ease. To account for these results, a prototype model of acquisition is introduced. Finally, differences between second language and foreign language-learning environments are discussed.

A sentence interpretation experiment based on the functionalist Competition Model of speech processing (Bates & MacWhinney, 1982) was administered to three groups of university-age English L1, Japanese ESL, and Japanese L1 subjects (n = 12 per group) in an attempt to elicit evidence for (1) processing strategies characteristic of the Japanese and English L1 groups and, (2) transfer/influence of Japanese L1 strategies on the English sentence interpretations of the Japanese ESL group. Subjects selected the subject/actor of simple sentences incorporating word order, animacy, and stress cues in random converging and competing orders. The English L1 and ESL groups were tested on English sentences and the Japanese L1 group tested on Japanese sentences. The Japanese L1 interpretations were most heavily influenced by animacy cues, while the English L1 group showed a higher overall sensitivity to word order manipulations. The ESL group resembled the Japanese L1 group in reliance on animacy cues, with the exception of allowing inanimate nouns to act as subjects. While the ESL group showed greater sensitivity to word order effects than the Japanese L1 group, no “second-noun” strategy (i.e., systematically interpreting the NNV and VNN orders as left- and right-dislocated SOV and VOS orders) was evident.

Although the findings were generally consistent with previous research, the presence of contrasting response patterns in the English L1 group suggests caution in attempting to typify languages on the basis of processing strategies drawn from probablistic tendencies evident in grouped data, and leaves open the role of such processing strategy typologies as a potential source of variation in inter-language.

Speakers of English and Dutch vary in how strongly they use various syntactic (e.g., word order, prepositions, case inflection) and semantic (e.g., noun animacy) cues to interpret native language sentences. For example, in simple NVN sentences, English speakers rely heavily on word order, while Dutch speakers rely on case inflection. This paper compares the cue usage of English/Dutch and Dutch/English bilinguals with varying amounts of second language exposure to that of native speaker control groups. For all constructions tested, dative constructions, simple NVN sentences, and relative clauses, it was found that with increasing exposure, cue usage in the second language gradually shifts from that appropriate to the first language to that appropriate to the second. A model of cue learning originally proposed to account for monolingual data is found to be compatible with the learning pattern exhibited by bilinguals.

This study is concerned with the probabilistic nature of processing strategies in bilingual speakers of Dutch and English. We used a sentence interpretation task designed to set up various “coalitions” and “competitions” among a restricted set of grammatical entities (i.e., word order, animacy, agreement). Performance in English paralleled that in Dutch in large measure, but where it diverged it approached performance on similar tasks by English monolinguals (Bates et al., 1982). These findings are interpreted on the basis of the “competition model,” a probabilistic theory of grammatical processing which provides a formalism for explaining what it means for a second language user to be “between” languages.
