Word frequencies in natural language follow a highly skewed Zipfian distribution, but the consequences of this distribution for language acquisition are only beginning to be understood. Typically, learning experiments that are meant to simulate language acquisition use uniform word frequency distributions. We examine the effects of Zipfian distributions(More)
Word frequencies in natural language follow a Zipfian distribution. Artificial language experiments that are meant to simulate language acquisition generally use uniform word frequency distributions, however. In the present study we examine whether a Zipfian frequency distribution influences adult learners' word segmentation performance. Using two(More)
Significance of the topic The experimental study of cultural evolution, social learning , cooperation, and collective decision-making asks fundamental questions about our capacities to learn, decide, and communicate in a world that is shared with other people. Experimental studies of cultural evolution have revealed a wealth of findings, including how(More)
Current computational models of word learning make use of correspondences between words and observed referents, but as of yet cannot—as human learners do—leverage information regarding the meaning of other words in the lexicon. Here we develop a Bayesian framework for word learning that learns a lexicon from multiword utterances. In a set of three(More)
Changes in language processing and production accompanying aging have most commonly been interpreted as evidence for age-related cognitive decline. A recent proposal (Ram-scar et al., 2014) challenges that interpretation, asserting instead that such changes emerge as a consequence of—and in order to support—processes of lifelong learning like continued(More)
In the classic telephone game, the content of a spoken message evolves as it passes from player to player. Beyond its entertainment value, the telephone game may have considerable scientific utility: Here we investigate the nature of the linguistic knowledge people use to comprehend language by tracking the evolution of a set of visually-presented sentences(More)
The English definite and indefinite articles (also known as de-terminers) are a useful index of early morphosyntactic productivity in children's speech, and give evidence about chil-dren's representation of syntactic abstractions. Previous work (i.e. Pine & Lieven, 1997) used a measure of productivity that shows a strong sensitivity to sample size and does(More)
Lexical dependencies abound in natural language: words tend to follow particular words or word categories. However, artificial language learning experiments exploring word segmen-tation have so far lacked such structure. In the present study, we explore whether simple inter-word dependencies influence the word segmentation performance of adult learners. We(More)
