The term "recursion" is used in at least four distinct theoretical senses within cognitive science. Some of these senses in turn relate to the different levels of analysis described by David Marr some 20 years ago; namely, the underlying competence capacity (the "computational" level), the performance operations used in real-time processing (the…

Previous evidence suggests that when speakers produce sentences from memory or as picture descriptions, their choices of sentence structure are influenced by how easy it is to retrieve sentence material (accessibility). Three experiments assessed whether this pattern holds in naturalistic, interactive dialogue. Pairs of speakers took turns asking…

At the one-word stage children use gesture to "supplement" their speech ("eat" + point at cookie), and the onset of such supplementary gesture-speech combinations predicts the onset of two-word speech ("eat cookie"). Gesture thus signals a child's readiness to produce two-word constructions. The question we ask here…

Humans have knowledge about the properties of their native language at various levels of representation; sound, structure, and meaning computation constitute the core components of any linguistic theory. Although the brain sciences have engaged with representational theories of sound and syntactic structure, the study of the neural bases of…

This study provides an account of the distributional information and the production rates in a particularly rich corpus of German child and adult language. Three structural domains are analysed: the parts-of-speech distribution for a coded corpus of circa one million words as well as the internal constituency of 300,000 noun phrases and almost…

The role of morphological, semantic, and form-based factors in the early stages of visual word recognition was investigated across different SOAs in a masked priming paradigm, focusing on English derivational morphology. In a first set of experiments, stimulus pairs co-varying in morphological decomposability and in semantic and orthographic…

Recent research in psychology and neuroscience has demonstrated that co-speech gestures are semantically integrated with speech during language comprehension and development. The present study explored whether gestures also play a role in language learning in adults. In Experiment 1, we exposed adults to a brief training session presenting novel…

The current study examines whether young and older adults have similar preferences for animate-subject and active sentences, and for using the order of activation of a verb's arguments to determine sentence structure. Ninety-six participants produced sentences in response to three-word stimuli that included a verb and two nouns differing in…
