Psycholinguistics: a cross-language perspective.

Cross-linguistic studies are essential to the identification of universal processes in language development, language use, and language breakdown. Comparative studies in all three areas are reviewed, demonstrating powerful differences across languages in the order in which specific structures are acquired by children, the sparing and impairment of those structures in aphasic patients, and the structures that normal adults rely upon most heavily in real-time word and sentence processing. It is proposed that these differences reflect a cost-benefit trade-off among universal mechanisms for learning and processing (perception, attention, motor planning, memory) that are critical for language, but are not unique to language.

Effect of grammatical gender and semantic context on lexical access in Italian.

The interacting effects of sentence context and grammatical gender on lexical access were investigated in Italian using a timed picture-naming paradigm. Results showed large interacting effects of both sentence context and the gender of the article, with facilitation relative to two different control conditions. Repeat testing yielded an overall decrease in RT, but did not change the pattern of results. Results are interpreted in support of interactive activation models in which different sources of information are combined "on-line" to predict, anticipate or preactivate lexical targets.

Gender priming in Italian.

The goals of the present study were (1) to determine whether grammatical gender on a noun modifier can prime recognition of the following noun, (2) to determine whether the priming effect involves facilitation, inhibition, or both, and (3) to compare performance across three different tasks that vary in the degree to which explicit attention to gender is required, including word repetition, gender monitoring, and grammaticality judgment. Results showed a clear effect of gender priming, involving both facilitation and inhibition. Priming was observed whether or not the subjects' attention was directed to gender per se. Results suggest that gender priming involves a combination of controlled postlexical processing and automatic prelexical processing. Implications for different models of lexical access are discussed, with special reference to modular versus interactive-activation theories.

Gender and lexical access in Italian.

Two new procedures were employed to investigate the effects of semantic and grammatical gender on lexical access in Italian and to investigate the interaction of gender with other factors that are known to influence lexical access in other languages. The gender-monitoring task requires a conscious decision about the gender of each noun, whereas the word repetition task does not require explicit attention to gender. In both tasks, single words are presented out of context, under speeded conditions. Both procedures proved to be sensitive indices of word recognition, with reaction times that are closely tied to the point at which words can be uniquely identified (although some processing before and after the uniqueness point was seen). In both tasks, reaction times were strongly affected by phonological factors (e.g., length, number of syllables, and presence of frication on the initial consonant). Phonological transparency of gender marking had a reliable effect on gender monitoring but had no effect on word repetition, suggesting that explicit attention to gender may be a factor affecting utilization of this phonological cue. Semantic factors (including semantic gender) had no effect on performance. Frequency and age of acquisition had very small effects when other factors were controlled. Implications for current models of lexical access are discussed, with special reference to the role of gender.

A cross-linguistic study of the development of sentence interpretation strategies.

Studies of the development of sentence comprehension strategies in English have indicated that, at first, children tend to rely on pragmatic and semantic strategies, whereas, later on, they rely primarily on word order to determine the basic grammatical relations. However, before making strong conclusions regarding the role of semantics in comprehension, it is necessary to distinguish between (1) extragrammatical knowledge of world events and (2) abstract semantic distinctions that may be an integral part of the parsing process. An earlier study of American and Italian adults indicated that use of such abstract semantic strategies may be a core strategy for parsing in Italian. In the present study, we compared sentence interpretation in American and Italian children between the ages of 2 and 5. From the earliest stages, children showed sensitivity to the relative information value of the various cues in their native language; Italians relied primarily on semantic cues, whereas American children relied on word order. In general, the data did not support claims regarding the existence of universal hypotheses about language structure. There was also evidence that the failure of these young children to make full use of certain interpretive cues resulted from their inability to appreciate the discourse functions of these cues.
