“…The publication record that Kidd and Garcia analyze is evidence that acquisition theories command inordinate attention in the field (Sarvasy, 2021). Textbooks on language acquisition detail theory but not language diversity.…”

The commentary amplifies Kidd and Garcia’s call for increased attention to language diversity in research on language acquisition by noting several implications of language diversity for acquisition theory and practice. An examination of the languages discussed in six recent articles on acquisition theory echos Kidd and Garcia’s observations on the inordinate role that better-studied languages play in acquisition research. Documenting the acquisition of 7,000 languages over the coming decade requires a new infrastructure for acquisition research. Sketches of child languages offer a community-based solution to processing bottlenecks and promote the use of indigenous languages.

A prosodic account of complex predicate acquisition in Mam: A Mayan language

The Mayan language Mam uses complex predicates to express events. Complex predicates map multiple semantic elements onto a single word, and consequently have a blend of lexical and phrasal features. The chameleon-like nature of complex predicates provides a window on children’s ability to express phrasal combinations at the one-word stage of language development. The ubiquity of complex predicates in the adult language insures that children will produce complex predicates as some of their first words. The verb complex in Mam has obligatory inflections for aspect, person, and to a degree direction. The inflections vary in degree of attachment between syllable segments, affixes, and clitics. Inflections with vowels are phonologically free, while inflections without vowels attach as either syllable segments or affixes. The Mam verb complex requires the addition of a phrasal layer to prosodic models of lexical acquisition. The paper used this extended version of prosodic theory to make five predictions for the acquisition of the verb complex. The paper analyzes production data for three children between 2;0 and 2;8 acquiring the northern variety of Mam spoken in San Ildefonso Ixtahuacán, Guatemala. The children’s production data for both the intransitive and transitive verb complexes support all five predictions to some degree. The children produced prefixes more frequently on vowel-initial stems than on consonant-initial stems, and they produced imperative suffixes more frequently than prefixes on consonant-initial stems. The children exhibited developmental differences and produced phrasal contractions that the prosodic theory did not predict. The results underline the need to integrate prosody into models of morphosyntactic development, and highlight the significance of complex predicates for theories of language acquisition.

In many communities around the world, speech to infants (IDS) and small children (CDS) has increased mean pitch, increased pitch range, increased vowel duration, and vowel hyper-articulation when compared to speech directed to adults (ADS). Some of these IDS and CDS features are also attested in foreigner-directed speech (FDS), which has been studied for a smaller range of languages, generally major national languages, spoken by millions of people. We examined vowel acoustics in CDS, conversational ADS, and monologues directed to a foreigner (possible FDS, labeled MONO here) in the Towet dialect of the Papuan language Nungon, spoken by 300 people in a remote region in northeastern Papua New Guinea. Previous work established that Nungon CDS entails optional use of consonant alteration, special nursery vocabulary, and special morphosyntax. This study shows that Nungon CDS to children aged 2;2–3;10 lacks vowel hyper-articulation, but still displays other common prosodic traits of CDS styles around the world: increased mean pitch and pitch range. A developmental effect was also attested, in that speech to 2-year-olds contained vowels that were significantly longer than those in speech to 3-year-olds, which in turn had vowels of similar duration to those in Nungon ADS. We also found that Nungon FDS vowel triangles, measured from monologues primarily directed to a non-native speaker, were significantly larger than those of either CDS or conversational ADS, indicating vowel hyper-articulation. The Nungon pattern may align with the patterns of vowels in Norwegian IDS, CDS, and FDS, where hyper-articulation is found in FDS, but not CDS or IDS. The languages of the New Guinea area constitute 20% of the world's languages, but neither an acoustic comparison of vowels in CDS and ADS, nor an acoustic study of FDS, has previously been completed for any language of New Guinea. The function of an FDS style in a small, closed community like those of much of New Guinea may differ from that in larger societies, since there are very few non-native speakers of Nungon. Thus, this study uses monologues recorded with a foreign researcher as interlocutor to study Nungon FDS.
