Starting in the late eighties, with a growing discontent with analytical methods in science and the growing power of computers, researchers began to study complex systems such as living organisms, evolution of genes, biological systems, brain neural networks, epidemics, ecology, economy, social networks, etc. In the early nineties, the research…

In broad terms, this paper is concerned with adjunct construction in Persian, which is an Indo-Iranian Language. During the recent century, specially in its final decades, different researches have been done about adjuncts and adjunction among different languages, but despite the fact that they are very important in Persian language, no attempts…

Direct instruction is often necessary to develop language or expand language use in individuals with language delays. Previous research has begun to identify certain training conditions that result in more efficient use of instructional time devoted to language development. Specifically, incorporating mands into the instructional arrangement,…

Recent challenges to Chomsky's "poverty of the stimulus" thesis for language acquisition suggest that children's primary data may carry "indirect evidence" about linguistic constructions despite containing no instances of them. Indirect evidence is claimed to suffice for grammar acquisition, without need for innate knowledge. This article reports…

The present article investigates the acquisition of the pronominal systems by French and Italian monolingual children and by bilingual German-French and German-Italian children, demonstrating a stable asymmetry: object and reflexive clitics are acquired later than nominative clitics and strong subject and object pronouns. We will widen the scope…

It has been suggested that the effect of word category in noun and verb processing reflects typical word class properties, which can be characterized in terms of semantic as well as syntactic and morphological features. The present study is aimed at differentiating and discussing the relative contribution of these aspects with a main focus on…

Native languages (L1s) are tacitly assumed to be complete and stable in adults. Here we report an unexpected individual variation in judgment of L1 regarding Japanese sentences including honorification, and further clarify its neural basis with functional magnetic resonance imaging (fMRI). By contrasting an honorification judgment task with a…

Suprasegmental acoustic patterns in speech can convey meaningful information and affect listeners' interpretation in various ways, including through systematic analog mapping of message-relevant information onto prosody. We examined whether the effect of analog acoustic variation is governed by the acoustic properties themselves. For example, fast…

Gradable adjectives denote a function that takes an object and returns a measure of the degree to which the object possesses some gradable property [Kennedy, C. (1999). Projecting the adjective: The syntax and semantics of gradability and comparison. New York: Garland]. Scales, ordered sets of degrees, have begun to be studied systematically in…

The current study on German investigates Event-Related brain Potentials (ERPs) for the perception of sentences with intonations which are infrequent (i.e. vocatives) or inadequate in daily conversation. These ERPs are compared to the processing correlates for sentences in which the syntax-to-prosody relations are congruent and used frequently…

Purpose: The aim of this study was to investigate the language outcomes of 7-year-old children with and without a history of late language emergence at 24 months. Method: One hundred twenty-eight children with a history of late language emergence (LLE) at 24 months and 109 children with a history of normal language emergence (NLE) at 24 months…

We report three experiments that investigated whether the linguistic behavior of participants in a dialogue is affected by their role within that interaction. All experiments were concerned with the way in which speakers choose between syntactic forms with very similar meanings. Theories of dialogue assume that speakers address their contributions…

From a conversation analytic perspective, this dissertation investigates how talk-in-turns in conversation are constructed and organized in a way that minimizes gaps and overlaps between speakers. Based on an informed assumption that turns are built out of turn units that allow the projection of their possible end points, I first characterize…

This study analyzes the user chat logs and other artifacts of a virtual world, "Quest Atlantis" (QA), and proposes the concept of Negotiation for Action (NfA) to explain how interaction, specifically, avatar-embodied collaboration between native English speakers and nonnative English speakers, provided resources for English language acquisition.…

This article tests a prediction made by Processability Theory (Pienemann, 1998; 2005) that morphological acquisition is the driving force in English as a second language (ESL) development. It first outlines the model of psycholinguistic processing assumed by Processability Theory and shows how stages fall out from it. It then presents the…
