Purpose: Variability in the input plays an important role in language learning. The current study examined the role of object variability for new word learning by preschoolers with specific language impairment (SLI). Method: Eighteen 4- and 5-year-old children with SLI were taught 8 new words in 3 short activities over the course of 3 sessions.…

Previous studies reveal an association between particular features of parental language input and advances in children's language learning. However, it is not known whether parent coaching aimed to enhance specific input components would (a) successfully increase these components in parents' language input and (b) result in concurrent increases in…

This study investigates Mandarin-speaking children's knowledge of event semantics in interpreting spatial modifiers with "zai" 'at' after a posture verb or before a placement verb. The event-semantic principles investigated include subevent modification (Parsons, 1990) and aspect shift (Fong, 1997). We conducted an experimental study…

Both the input directed to the child, and the child's ability to process that input, are likely to impact the child's language acquisition. We explore how these factors inter-relate by tracking the relationships among: (a) lexical properties of maternal child-directed speech to prelinguistic (7-month-old) infants (N = 121); (b) these infants'…

Adult learners know that language is for communicating and that there are patterns in the language that need to be learned. This affects the way they engage with language input; they search for form-meaning linkages, and this effortful engagement could interfere with their learning, especially for things like grammatical gender that often have at…

The present study was an attempt to examine the impact of input flooding (IF) and textual enhancement (TIE) on EFL learners' syntactic development. Four homogenous groups were selected based on the pre-test and placement tests. During the treatment, the first group (i.e., IF) received reading comprehension passages in which the structure was…

We trained forty German-speaking children aged 1;8-2;0 in their comprehension of UNTER [UNDER]. The target word was presented within semantically organized input in the form of a "narrative" to the experimental group and within "unconnected speech" to the control group. We tested children's learning by asking them to…
