To learn a language infants must learn to link arbitrary sounds to their meaning. While words are the clearest example of this link, they are not the only component of language; morphological regularities (e.g., the plural -s suffix in English) carry meaning as well. Comprehensive theories of language acquisition must account for how infants build…

A major problem in second language acquisition (SLA) is the segmentation of fluent speech in the target language, i.e., detecting the boundaries of phonological constituents like words and phrases in the speech stream. To this end, among a variety of cues, people extensively use prosody and statistical regularities. We examined the role of pitch,…

Our native tongue influences the way we perceive other languages. But does it also determine the way we perceive nonlinguistic sounds? The authors investigated how speakers of Italian, Turkish, and Persian group sequences of syllables, tones, or visual shapes alternating in either frequency or duration. We found strong native listening effects…

A large body of empirical research demonstrates that people exploit a wide variety of cues for the segmentation of continuous speech in artificial languages, including rhythmic properties, phrase boundary cues, and statistical regularities. However, less is known regarding how the different cues interact. In this study we addressed the question of…

The iambic-trochaic law has been proposed to account for the grouping of auditory stimuli: Sequences of sounds that differ only in duration are grouped as iambs (i.e., the most prominent element marks the end of a sequence of sounds), and sequences that differ only in pitch or intensity are grouped as trochees (i.e., the most prominent element…

We argue that the grammatical diversity observed among the world's languages emerges from the struggle between individual cognitive systems trying to impose their preferred structure on human language. We investigate the cognitive bases of the two most common word orders in the world's languages: SOV (Subject-Object-Verb) and SVO. Evidence from…

Learning word order is one of the earliest feats infants accomplish during language acquisition [Brown, R. (1973). "A first language: The early stages", Cambridge, MA: Harvard University Press.]. Two theories have been proposed to account for this fact. Constructivist/lexicalist theories [Tomasello, M. (2000). Do young children have adult…

Examines syllable-timed languages (Catalan, Greek, Italian) and stress-timed languages (English, Polish) to show that, in regard to rhythm, both categories behave similarly in several crucial areas. In both language types, the ideal rhythmic pattern involves a separation of stresses and the elimination of clashes. (33 references) (JL)

Traditional descriptions of Italian phonology have occasionally suggested that some type of connection exists between "raddoppiamento sintattico" (RS) and the word internal consonant length contrast. (RS is defined as a systematic lengthening of the first consonant of the second word in a two-word sequence in certain syntactic and phonological…
