When acquiring the English plural, children correctly produce plural words long before they develop an understanding of morphological structure. When acquiring Sesotho noun prefixes, children are aware of the multiple constraints governing variation from a young age. Both of these cases raise questions about the Shin and Miller (2022) account of…

This article questions how two very similar sets of experiments can yield such very different findings, and comments on the differences between the studies. Here Annamarie Kerkhoff presents a commentary on some perceived differences between the studies in areas such as age groups and group sizes evaluated. Kerkhoff also comments on some…

We present a neural network model of learning and processing the English past tense that is based on the notion that experience-dependent cortical development is a core aspect of cognitive development. During learning the model adds and removes units and connections to develop a task-specific final architecture. The model provides an integrated…

This special issue of the "Heritage Language Journal", guest edited by Silvina Montrul, unites four papers on different aspects of heritage Spanish speakers' linguistic abilities. In this commentary, we reexamine these important contributions with an eye toward implications for instruction and toward general trends for the field. In particular, we…

Baggio presents the results of an event-related potential (ERP) study in which he examines the processing consequences of reading tense violations such as *"Afgelopen zondag lakt Vincent de kozijnen van zijn landhuis" (*"Last Sunday Vincent paints the window-frames of his country house"). The violation is arguably caused by a mismatch between the…

Two experiments explored the representational basis for anticipatory eye movements. Participants heard "the man will drink ..." or "the man has drunk ..." (Experiment 1) or "the man will drink all of ..." or "the man has drunk all of ..." (Experiment 2). They viewed a concurrent scene depicting a full glass of beer and an empty wine glass (amongst…

Previous research suggests that children's behavior with respect to the interpretation of indefinite objects in negative sentences may differ depending on the target language: whereas young English-speaking children tend to select a surface scope interpretation (e.g., Musolino (1998)), young Dutch-speaking children consistently prefer an inverse…

As one of the best known linguistic constraints on code switching, Poplack (1980) has proposed the "free morpheme constraint," which predicts no switching between free morphemes and bound morphemes. It is argued that this theory is not supported by linguistic data, and that semantic content, rather than morphology, must be considered. An…

Examines certain instructional effects on second-language acquisition, such as code-focused instruction and classroom interaction. Empirical research on instructional effects are outlined in relation to some basic issues, including learning environment influences and processing constraints. (54 references) (GLR)
