This study undertook iconicity ratings and conducted transparency experiments on Israeli Sign Language (ISL). Experiment 1 compared the iconicity ratings of 520 lexical signs of ten Deaf ISL signers and thirteen hearing non-signers. Ratings were found to be affected by language knowledge, lexical class, and type of iconic mapping, as well as by…

Purpose: The purpose of the study was to evaluate implicit learning in children with developmental language disorder (DLD) by employing a visual artificial grammar learning task. Method: Thirteen children with DLD and 24 children with typical language development between the ages of 8 and 12 years completed a visual artificial grammar learning…

Previous studies show that infants store functional morphemes for inferring syntactic categories of adjacent words, and they generally perform better with nouns than with verbs. In this study, we tested whether toddlers can exploit phrasal groupings for syntactic categorization in the face of noisy co-occurrence patterns. Using a visual fixation…

Research consistently shows that adults engaged in tutored acquisition benefit from explicit instruction in several linguistic domains. For preschool children, it is often assumed that such explicit instruction does not make a difference. In the present study, we investigated whether explicit instruction affected young learners in acquiring a…

From limited evidence, children track the regularities of their language impressively fast and they infer generalized rules that apply to novel instances. This study investigated what drives the inductive leap from memorizing specific items and statistical regularities to extracting abstract rules. We propose an innovative entropy model that…

Two lines of evidence emerged in the past suggesting that lexical form seemed to play a more important role in the organization of the second language (L2) mental lexicon than in that of the first language (L1) lexicon. They were masked orthographic priming in L2 word recognition and an elevated proportion of form-related responses in L2 word…

Tasks with different design factors may dissimilarly affect oral production, and thus can be adopted for different pedagogical purposes. However, the functions of task types are not fully explored. To address this gap, this study investigates the influence of content familiarity and task repetition on sixty English as a foreign language learners'…

Two eye-tracking experiments tested (a) whether L2 learners benefit from the consistency of input modality (auditory instead of written processing instruction [PI] training) and (b) whether they benefit from training using the same voice as the test voice. Results confirmed a robust effect of PI training on picture-selection accuracy, yet the…

The aim of this study was twofold: first, to develop an experimental technique as a tool to investigate learning outcomes of spontaneous, naturalistic second language (L2) learning under controlled laboratory conditions; and second, to explore how this technique can be used to understand the basic conditions and limits of this learning. Two…

Despite many years of investigation into implicit learning in nonlinguistic domains, the potential for implicit learning to deliver the kinds of generalizations that underlie natural language competence remains unclear. In a series of experiments, we investigated implicit learning of the semantic preferences of novel verbs, specifically, whether…

It is commonly held that implicit knowledge expresses itself as fluency. A perceptual clarification task was used to examine the relationship between perceptual processing fluency, subjective familiarity, and grammaticality judgments in a task frequently used to produce implicit knowledge, artificial grammar learning (AGL). Four experiments…

In order to acquire some aspects of grammar, such as wh-questions and verb tense agreement, children must be able to learn nonadjacent dependencies. This type of learning has been demonstrated in both children and adults, but is reported to be difficult. The current study investigated whether children with autism (ASD) would show a similar pattern…

In this paper, I investigate the phenomenon of morphological variability in the production of Italian determiners, descriptive adjectives, and direct object pronouns by adult English learners of Italian to determine whether morphological errors are the result of computational or representational difficulties. Second language acquisitionists do…

In this article second language (L2) knowledge of Dutch grammatical gender is investigated. Adult speakers of German, English and a Romance language (French, Italian or Spanish) were investigated to explore the role of transfer in learning the Dutch grammatical gender system. In the first language (L1) systems, German is the most similar to Dutch…

Research in first language and second language (L2) comprehension has demonstrated that both learner and input variables contribute to the ease with which a message is understood. Questions remain, however, as to how these variables affect the way L2 learners process linguistic form during comprehension. This study examines how one learner…
