This study examines declarative memory retrieval in ASD depending on the availability and access to stored conceptual knowledge. Fifteen autistic participants and a matched control group of 18 typically-developed (TD) volunteers completed a Remember-Know paradigm manipulated by encoding-type (categorical, perceptual) and item-typicality…

Experimental studies show that children have greater difficulty with "wh"-extraction from object position than subject position, arguably an intervention effect (e.g., Relativized Minimality). In this study we provide additional evidence of a S/O asymmetry in A'-dependencies from a novel source--sluicing. The results of our first…

Previous research has suggested that Event-Related Potentials (ERPs) can index form-, meaning-, and use-related aspects of the second language (L2) vocabulary knowledge, through, respectively, a lexical decision task (LDT, targeting N400), a semantic relatedness task (SEMREL, targeting N400), and a grammatical judgment task (GJT, targeting…

The present study aimed to examine the role of phonological--semantic flexibility (PSF) in learning to read Chinese. PSF refers to a specific flexibility applied to process the dual linguistic dimensions of words (i.e., sound and meaning). A correlational study (Study 1) was conducted to determine the unique contribution of PSF to three aspects of…

The Interface Hypothesis proposes that the pragmatic-discursive interface with syntax is more vulnerable to crosslinguistic influence than the syntactic-semantic interface [Tsimpli, Ianthi, and Antonella Sorace. 2006. "Differentiating Interfaces: L2 Performance in Syntax- Semantics and Syntax-Discourse Phenomena." In Proceedings of the…

The present study is designed to investigate whether children's difficulties with subject-to-subject raising (StSR) are due to intervention effects. We examine English-speaking children's comprehension of StSR with "seem" and Spanish-speaking children's comprehension of StSR with "parecer" 'seem,' a configuration never before…

Executive function (EF) contributes significantly to reading comprehension across the lifespan. Emerging research indicates domain-specific assessments of EF are better suited for assessment and intervention in academic contexts. For example, "graphophonological-semantic cognitive flexibility" (GSF), the ability to flexibly switch…

Primary progressive aphasia (PPA) is a neurodegenerative condition characterized by language and cognitive decline. Word-retrieval deficits are the most common PPA symptom and contribute to impaired spoken expression. Intense semantic interventions show promise for improving word retrieval in people with PPA. In addition, people with PPA may learn…

This study examines the role of explicit instruction in article semantics to L2 learners of English. Two types of generic sentences, expressed by different articles, were tested over time. An instruction group (n = 21), a control group (n = 16) and a native English speaker control group (n = 9) participated in the study. The instruction group…

In an intelligent tutoring system (ITS), it can be useful to know when a student has disengaged from a task and might benefit from a particular intervention. However, predicting disengagement on a trial-by-trial basis is a challenging problem, particularly in complex cognitive domains. In the present work, data-driven methods were used to address…

Purpose: This article aims to describe how exemplar variability can manipulate the word learning environment to maximize within- and cross-language generalization in Spanish--English bilinguals. Furthermore, we examined sources of individual variability that predicted word learning. Method: Nineteen Spanish--English bilingual children participated…

This article investigates the acquisition of different types of clefts and of "be"-fragments in European Portuguese. We first present the main syntactic and discourse properties of different cleft structures and of "be"-fragments in European Portuguese, and we discuss how data from first language acquisition may contribute to…

Atypical expressive prosody is reported as a consistent challenge for individuals with Autism Spectrum Disorder (ASD) and is associated with a broad set of clinical impairments including perceptions of oddness from others. Theories of atypical prosody in ASD have attributed these impairments to the broader symptoms of ASD, particularly in the…

Many studies suggest that long-term lexical-semantic knowledge is an important determinant of verbal short-term memory (STM) performance. This study explored the impact of emotional valence on word immediate serial recall as a further lexico-semantic long-term memory (LTM) effect on STM. This effect is particularly interesting for the study of…

Learning new vocabulary words in a second language is a challenge for the adult learner, especially when the second language writing system differs from the first language writing system. According to the lexical quality hypothesis (Perfetti & Hart, 2001), there are three constituents to word-level knowledge: orthographic, phonological, and…
