The prosodic encoding of information structure (IS) is mastered fairly late in children’s language development according to previous research (e.g., MacWhinney & Bates, 1978; de Ruiter, 2010). However, few studies have conducted parallel production and perception experiments to study the relation between children’s encoding and decoding of prosodically marked IS (Chen, 2010); earlier studies involving perception have made use of offline paradigms (e.g., Wells et al., 2004), while more recent studies using online methods such as eye tracking have usually not been complemented by production data (e.g., Ito, 2014). In addition, previous production work has indicated that language-specific aspects of IS coding might play a role, too (e.g., Romøren & Chen, 2015, 2021; Prieto & Esteve-Gibert, 2018). In this study, we explore the production and perception of intonationally marked contrastive focus in 3-5-year-old children speaking either Scanian or Stockholm Swedish, two dialects that differ crucially in the way the focus is encoded phonologically. While both dialects exhibit a lexical accent contrast, focus is phonetically marked more subtle in the Scanian variety: instead of adding a prominence H(igh)-tone for focus, phrase-level prominence is encoded through phonetic adjustments of the H(ihg)-L(ow) accent patterns determined by the lexical accent contrast. By comparing these two Swedish varieties we can thus control for other phonological features (incl. lexical tone), as well as grammar and lexicon. Our production experiment involves eliciting adjective-noun phrases in three different focus conditions, using an interactive video/card game. Production data are analyzed acoustically and auditorily. In our visual-word eye-tracking experiment we use the same pictures of colored objects as in the production experiment to investigate whether and how children make use of contrastive intonation for reference resolution. Eye-tracking data are analyzed using growth curve analysis (Mirman, 2014). Data are currently being collected, and preliminary results will be presented at the conference.
