When speakers describe motion events using different languages, they subsequently classify those events in language-specific ways (Gennari, Sloman, Malt & Fitch, 2002). Here we ask if bilingual speakers flexibly shift their event classification preferences based on the language in which they verbally encode those events. English–Spanish bilinguals and monolingual controls described motion events in either Spanish or English. Subsequently they judged the similarity of the motion events in a triad task. Bilinguals tested in Spanish and Spanish monolinguals were more likely to make similarity judgments based on the path of motion versus bilinguals tested in English and English monolinguals. The effect is modulated in bilinguals by the age of acquisition of the second language. Late bilinguals based their judgments on path more often when Spanish was used to describe the motion events versus English. Early bilinguals had a path preference independent of the language in use. These findings support “thinking-for-speaking” (Slobin, 1996) in late bilinguals
Disagreement exists about how bilingual speakers select words, in particular, whether words in another language compete, or competition is restricted to a target language, or no competition occurs. Evidence that competition occurs but is restricted to a target language comes from response time (RT) effects obtained when speakers name pictures in one language while trying to ignore distractor words in another language. Compared to unrelated distractor words, RT is longer when the picture name and distractor are semantically related, but RT is shorter when the distractor is the translation of the name of the picture in the other language. These effects suggest that distractor words from another language do not compete themselves but activate their counterparts in the target language, thereby yielding the semantic interference and translation facilitation effects. Here, we report an event-related brain potential (ERP) study testing the prediction that priming underlies both of these effects.The RTs showed semantic interference and translation facilitation effects. Moreover, the picture-word stimuli yielded an N400 response, whose amplitude was smaller on semantic and translation trials than on unrelated trials, providing evidence that interference and facilitation priming underlie the RT effects. We present the results of computer simulations showing the utility of a within-language competition account of our findings.
It has been argued that inhibition is a mechanism of attentional control in bilingual language performance. Evidence suggests that effects of inhibition are largest in the tail of a response time (RT) distribution in non-linguistic and monolingual performance domains. We examined this for bilingual performance by conducting delta-plot analyses of naming RTs. Dutch–English bilingual speakers named pictures using English while trying to ignore superimposed neutral Xs or Dutch distractor words that were semantically related, unrelated, or translations. The mean RTs revealed semantic, translation, and lexicality effects. The delta plots leveled off with increasing RT, more so when the mean distractor effect was smaller as compared with larger. This suggests that the influence of inhibition is largest toward the distribution tail, corresponding to what is observed in other performance domains. Moreover, the delta plots suggested that more inhibition was applied by high- than low-proficiency individuals in the unrelated than the other distractor conditions. These results support the view that inhibition is a domain-general mechanism that may be optionally engaged depending on the prevailing circumstances.
This paper argues for a gradient approach to word order, which treats word order preferences, both within and across languages, as a continuous variable. Word order variability should be regarded as a basic assumption, rather than as something exceptional. Although this approach follows naturally from the emergentist usage-based view of language, we argue that it can be beneficial for all frameworks and linguistic domains, including language acquisition, processing, typology, language contact, language evolution and change, variationist linguistics and formal approaches. Gradient approaches have been very fruitful in some domains, such as language processing, but their potential is not fully realized yet. This may be due to practical reasons. We discuss the most pressing methodological challenges in corpus-based and experimental research of word order and propose some solutions and best practices.
Animals across phyla can detect early cues of infection in conspecifics, thereby reducing the risk of contamination. It is unknown, however, if humans can detect cues of sickness in people belonging to communities with whom they have limited or no experience. To test this, we presented Western faces photographed 2 h after the experimental induction of an acute immune response to one Western and five non-Western communities, including small-scale hunter–gatherer and large urban-dwelling communities. All communities could detect sick individuals. There were group differences in performance but Western participants, who observed faces from their own community, were not systematically better than all non-Western participants. At odds with the common belief that sickness detection of an out-group member should be biased to err on the side of caution, the majority of non-Western communities were unbiased. Our results show that subtle cues of a general immune response are recognized across cultures and may aid in detecting infectious threats.
and ARC Centre for the Dynamics of Language of Excellence for the Dynamics of Language Psycholinguistic theories are based on a very small set of unrepresentative languages, so it is as yet unclear how typological variation shapes mechanisms supporting language use. In this article we report the first on-line experimental study of sentence production in an Australian free word order language: Murrinhpatha. Forty-six adult native speakers of Murrinhpatha described a series of unrelated transitive scenes that were manipulated for humanness (±human) in the agent and patient roles while their eye movements were recorded. Speakers produced a large range of word orders, consistent with the language having flexible word order, with variation significantly influenced by agent and patient humanness. An analysis of eye movements showed that Murrinhpatha speakers' first fixation on an event character did not alone determine word order; rather, early in speech planning participants rapidly encoded both event characters and their relationship to each other. That is, they engaged in relational encoding, laying down a very early conceptual foundation for the word order they eventually produced. These results support a weakly hierarchical account of sentence production and show that speakers of a free word order language encode the relationships between event participants during earlier stages of sentence planning than is typically observed for languages with fixed word orders.*
