Do dialect-specific prosodic properties shape the path to contrastive focus? - Production and comprehension data from 3-5 year-old children acquiring Stockholm or Scania Swedish

Konferensbidrag (refereegranskat)abstract
- Cuing information structure (IS) is a fundamental function of prosody in many languages. For instance, in English or Dutch, a contrastive focus on the color adjective in a phrase like ‘the green boat’ is marked by a pitch accent on GREEN and, crucially, a lack of post-focal accent on BOAT: ‘the GREEN boat’. Listeners infer from this prosodic structure that ‘boat’ represents already activated (given) information and that the color that is specially mentioned represents one out of a set of alternatives.According to research findings, children achieve proficiency in the production of prosodic IS encoding within the age range of 4 to 8 years, displaying considerable variability. This variability is suggested to result from structural prosodic differences between languages. For instance, Stockholm Swedish speaking children mark (non-contrastive) focus using the Swedish prominence cuing H(igh) tone in an adult-like manner already at 4-5 years, while Dutch speaking children handle Dutch intonational pitch accents only after the age of 7-8 years. One hypothesis is that this relates to the presence of lexical pitch accents in Swedish, which could make Swedish speaking children more sensitive to prosodic contrasts; in addition, the combination of lexical accent + prominence H results in a complex contour which is particularly salient. However, studies investigating this have usually had a strict focus on speech production.The few previous studies that have conducted parallel production and comprehension experiments have typically used offline methods to assess comprehension. More recent studies using online methods such as eye tracking have usually not included children younger than 6 years of age and have not been complemented by production data. In this study we combine production and comprehension experiments, using eye tracking, to study contrastive focus prosody in 3- to 5-year-old children speaking either Scanian or Stockholm Swedish. In Scanian, instead of adding the prominence H-tone for focus, phrase-level prominence is encoded through phonetic adjustments of the (lexical) HL accent patterns. By comparing these two Swedish varieties we can thus control for phonological features (incl. lexical tone), as well as grammar and lexicon, when exploring effects of prosodic-typological differences.In our production experiment we elicit adjective-noun phrases in three different focus conditions (broad, contrast on adjective, contrast on noun), using an interactive video/card game. Production data are analyzed acoustically and auditorily.As for comprehension, our visual-word eye-tracking experiment makes use of the same pictures of colored objects to investigate whether and how children rely on prosody for reference resolution (e.g., Where is the yellow boat? And where is the GREEN boat?). The time course of eye movements will be analyzed using growth curves. Both production and eye-tracking data will be analyzed as a function of dialect, age and standardized measures of language production and comprehension (The New Reynell Developmental Language Scales), as well as compared to data from adult controls. Data are currently being collected. A preliminary analysis of eye-tracking data from 24 Scanian children (ages 3-5 years collapsed) and a subset of adults from both dialects suggests similar comprehension of focus prosody as in adults (as a mismatched focus prosody in the adjective successfully elicits looks at the foil item in all groups), although processing appears to be slower, and anticipatory strategies differ slightly from those of adults (as the color of the first-mentioned adjective in a trial elicits looks at the color-matched distractor in adults, but not in children). An analysis contrasting comprehension data for both dialects, as well as a preliminary analysis of production data will be presented at the conference.

Språkutveckling och prosodisk typologi: Produktion och perception av den dialektspecifika fokusmarkeringen hos 3- till 5-åriga barn från Stockholm och Skåne
- 2023

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Att lägga satsbetoningen på ordet som bör fokuseras utifrån en given informationsstruktur är något som barn enligt tidigare internationell forskning verkar bemästra relativt sent i utvecklingen av sitt förstaspråk. Förmågan att uppfatta och tolka satsbetoning verkar barn enligt vissa studier utveckla ännu senare, men få tidigare studier har genomfört parallella produktions- och perceptionstest, och få perceptionsstudier har i detta sammanhang använt sig av online metoder (så som ögonrörelsemätning) med barn yngre än sex år. En del tidigare studier har påvisat typologiska skillnader; till exempel verkar svenska barn kunna producera en vuxenlik fokusbetoning tidigare än nederländska barn.Med vår studie ämnar vi bidra till en bättre förståelse av hur barn utvecklar sin förmåga att producera och uppfatta kontrastiva fokusbetoningar (t. ex. en röd BIL, en RÖD bil), hur produktionen och perceptionen hänger ihop, och vilken roll prosodisk språktypologi kan spela i sammanhanget. Vi undersöker dessa förmågor hos (totalt ca 120) förskolebarn med stockholmsvenska respektive skånska som förstaspråk – två dialekter som representerar motpoler i en prosodisk typologi när det gäller hur satsbetoning kodas intonationsfonologiskt. I vår produktionsstudie eliciterar vi adjektiv-substantiv fraser med varierad kontrastiv fokus, och i perceptionsstudien mäter vi barnens bearbetning av prosodin i liknande fraser med hjälp av ögonrörelsemätning. Datainsamling pågår i skrivande stund, och prelimära resultat kommer att presenteras på workshopen.
