This study was designed to provide a general picture of infant vocal –motor coordination and test predictions generated by Iverson and Thelen’s (1999) model of the development of the gesture – speech system. Forty-seven 6- to 9-month-old infants were videotaped with a primary caregiver during rattle and toy play. Results indicated an age-related increase in frequency of vocal –motor coordination, greater coordination with arm (specifically right arm) than leg or torso movements, and a temporal pattern similar to that in adult gesture – speech co-productions. Rhythmic vocalizations (consonant – vowel repetitions) were more likely to occur with than without rhythmic movement, and with rhythmic manual than with nonmanual activity, and the rate of vocal – manual coordination was higher in babblers than in prebabblers. Speakers in cultures the world over produce spon-taneous hand gestures, and these gestures are tightly linked to contemporaneous speech. The strength of this link has been demonstrated in gesture suppres-sion experiments and in studies of communication among blind individuals. Thus, for example, narra-tives produced with gestures prohibited are more

A fundamental, universal property of human language is that its phonology is combinatorial. That is, one can identify a set of basic, distinct units (phonemes, syllables) that can be productively combined in many different ways. In this paper, we develop a methodological framework based on evolutionary game theory for studying the evolutionary transition from holistic to combinatorial signal systems, and use it to evaluate a number of existing models and theories. We find that in all problematic linguistic assumptions are made or crucial components of evolutionary explanations are omitted. We present a novel model to investigate the hypothesis that combinatorial phonology results from optimizing signal systems for perceptual distinctiveness. Our model differs from previous models in three important respects. First, signals are modeled as trajectories through acoustic space; hence, both holistic and combinatorial signals have a temporal structure. Second, acoustic distinctiveness is defined in terms of the probability of confusion. Third, we show a path of ever increasing fitness from unstructured, holistic signals to structured signals that can be analyzed as combinatorial. On this path, every innovation represents an advantage even if no-one else in a population has yet obtained it. Key words: evolution of language; evolutionary phonology; simulations; phonemic coding
Syllables as Processing Units in Handwriting Production

This research focused on the syllable as a processing unit in handwriting. Participants wrote, in uppercase letters, words that had been visually presented. The interletter intervals provide information on the timing of motor production. In Experiment 1, French participants wrote words that shared the initial letters but had different syllable boundaries. In Experiment 2, French- and Spanish-speaking participants wrote cognates and pseudowords with a letter sequence that was always intrasyllabic in French and intersyllabic in Spanish. In Experiment 3, French–Spanish bilinguals wrote the cognates and pseudowords with the same type of sequences. In the 3 experiments, the critical interletter intervals were longer between syllables than within syllables, indicating that word syllable structure constrains motor production both in French and Spanish.

This paper deals with rhythmic modeling and its application to language identification. Beside phonetics and phonotactics, rhythm is actually one of the most promising features to be considered for language identification, but significant problems are unresolved for its modeling. In this paper, an algorithm dedicated to rhythmic segmentation is described. Experiments are performed on read speech for 5 European languages. Several algorithms are compared. They show that salient features may be automatically extracted and efficiently modeled from the raw signal: a linear discriminant analysis of the extracted features results in a 80 % percent of correct language identification for the 5 languages, using 20 s duration utterances. Additional experiments reveal that the automatic rhythmic units convey also speaker specific features. 1.

Full understanding of the nature of speech acquisition requires exploration of both produc-tion and perception factors. Jakobson (1968) proposed the universal primacy of perceptual factors in the systematic development of a child’s production repertoire. Subsequent studies have refuted his claim of a universal developmental sequence (e.g., Macken, 1992). Recent work has emphasized the importance of child-internal production factors for understanding characteristics of speech acquisition in the prelinguistic and early word

This article investigates the role that nonverbal actions play in language processing over 3 different time frames. First, we speculate that nonverbal actions played a role in how formal language systems emerged from our primate ancestors over evolutionary time. Next, we hypothesize that if nonverbal behaviors played a foundational role in the emergence of language over evolution, these actions should influence how children learn language in the present. Finally, we argue that nonverbal actions continue to play a role for adults in the moment-to-moment processing of language. Throughout, we take an embodied view of language and argue that the neural, cognitive, and social components of language processing are firmly grounded in bodily action. Human language is special because it is at the pinnacle of the mind’s capabilities and is most notably what separates our minds from the minds of other thinking an-imals. Language is so special, in fact, that many people have argued that there is a designated language device built into the human brain at birth.
