Previous research has argued that learners infer word order pat-terns when learning a new language based on knowledge aboutunderlying structure, rather than linear order (Culbertson &Adger, 2014). Specifically, learners prefer typologically com-mon noun phrase word order patterns that transparently reflecthow elements like nouns, adjectives, numerals, and demon-stratives combine hierarchically. We test whether this resultstill holds after removing a potentially confounding strategypresent in the original study design. We find that when learn-ers are taught a naturalistic “foreign” language, a clear prefer-ence for noun phrase word order is replicated but for a subsetof modifier types originally tested. Specifically, participantspreferred noun phrases with the order N-Adj-Dem (as in “mugred this”) over the order N-Dem-Adj (as in “mug this red”).However, they showed no preference between orders N-Adj-Num (as in “mugs red two”) and N-Num-Adj (as in “mugstwo red”). We interpret this sensitivity as potentially reflectingan asymmetry among modifier types in the underlying hierar-chical structure.

The syntactic behaviour of human beings cannot be explained by analogical generalization on the basis of concrete exemplars: analogies in surface form are insufficient to account for human grammatical knowledge, because they fail to hold in situations where they should, and fail to extend in situations where they need to.

There is a long-standing debate in cognitive science surrounding the source of commonalities among languages of the world. Indeed, there are many potential explanations for such commonalities—accidents of history, common processes of language change, memory limitations, constraints on linguistic representations, and so on. Recent research has used psycholinguistic experiments to provide empirical evidence linking common linguistic patterns to specific features of human cognition, but these experiments tend to use English speakers, who in many cases have direct experience with the common patterns of interest. Here we highlight the importance of testing populations whose languages go against cross-linguistic trends. We investigate whether adult monolingual speakers of Kîîtharaka, which has an unusual way of ordering words, mirror the word-order preferences of English speakers. We find that they do, supporting the hypothesis that universal cognitive representations play a role in shaping word order. [ABSTRACT FROM AUTHOR]
