This paper explores the acquisition of personal reference terms in Thai, a language with a highly complex personal reference system. Two separate studies were conducted for this paper, each featuring two groups of participants: children with typical development (TD) and children with autism spectrum disorders (ASDs). In each study, the…

The paper reports on two experiments that investigate whether polarity, clause order and incentive influence derivation of Conditional Perfection in two types of inducements (promises and threats). Both experiments are designed as inference tasks, additionally measuring reaction times to inferences. The paper shows that the derivation of…

Hudson Kam (2018) examined whether learning of a particular aspect of language that adults are known to have difficulty with (grammatical gender) could be improved by manipulating the learning experience of adults so that it was more like that of infants. Specifically, based on likely differences between adult and child learners' experiences as…

This study concerns the development of the determiners MINE/MY and THINE/THY in the Early Modern English period. The -N forms had essentially been ousted before words starting with consonants over the Middle English period, and over the subsequent centuries, these forms also fell into disuse before words starting with initial vowels and…

This article examines children's comprehension of the "get"-passive relative to the "be"-passive in an attempt to systematically compare the acquisition of both types of passives. It discusses the findings of two experiments (a picture-matching task and an act-out task) with children ages 36. Results from the picture-matching…

Research in language development has only recently begun to focus on the inherent variability of language. Previous studies have explored at what age children begin to produce variable linguistic forms and how these forms progress through development. While children produce adult-like variation early on, some variable forms take longer to acquire…

The construct of awareness plays a pivotal role in several big debates in the field of second language acquisition. It lies at the heart of discussions about the (im)possibility of learning without awareness, or conversely, whether some degree of awareness is a requirement for learning to take place. In this study, I propose a research agenda to…

The current study examined the occurrence and benefits of linguistic alignment in two modalities, face-to-face (FTF) and synchronous computer-mediated communication (SCMC), focusing on stranded prepositions in relative clauses. It further examined how learner characteristics (i.e., working memory, language proficiency, previous knowledge of the…

Different words generally have different meanings. However, some words seemingly share similar meanings. An example are null and overt pronouns in Italian, which both refer to an individual in the discourse. Is the interpretation and processing of a form affected by the existence of another form with a similar meaning? With a pupillary response…

The extensive literature on subject expression in Spanish makes for rich comparisons between generative (formal) and usage-based (functional) approaches to language acquisition. This article explores how the problem of subject expression has been conceptualized within each research tradition, as well as unanswered questions that both approaches…

Previous studies in the acquisition of clitic se in Spanish have focused on the syntactic processes needed to perform detransitivization. However, current approaches on event structure reveal that "se" encodes aspectual information which is crucial for its acquisition. We examine the use, intuition and interpretation of the aspectual…

Statements containing quantity information are commonplace. Although there is literature explaining the way in which quantities themselves are conveyed in numbers or words (e.g., "many", "probably"), there is less on the effects of different types of quantity description on the processing of surrounding text. Given that…

We test the interpretation of pronominal forms in L2 speakers of English whose L1 is Spanish. Previous research on learners of nonnull subject languages has shown conflicting results. The aim of the present study is to reconcile previous evidence and shed light on the factors that determine learners' difficulty to interpret pronominal forms in the…

While previous sociolinguistic research has demonstrated that children faithfully acquire probabilistic input constrained by sociolinguistic and linguistic factors (e.g., gender and socioeconomic status), research suggests children regularize inconsistent input-probabilistic input that is not sociolinguistically constrained (e.g., Hudson Kam &…

Research on linguistic variation suggests that usage patterns are deeply embedded in native and non-native speakers' knowledge of grammar. This study explores the transfer of these variable sociolinguistic patterns at the initial stages of third language acquisition. We elicited narratives in Portuguese from two mirror-image groups of sequential…
