Previous experimental work shows that negation processing can be direct in bipolar contexts where positive/negative states of affairs can be expressed by available lexical opposites (remember/forget) in monolingual speakers. However, in a unipolar context where such opposites are not available (sing/not sing), the processing first proceeds through…

Unlike with the typically developing population, non-typically developing individuals, especially those with intellectual disabilities, have usually been recommended to learn and use only one language, despite perhaps coming from bilingual families or living in multilingual environments. This common practice, however, is not backed by empirical…

The present study examined cross-linguistic differences in morphological processing in the visual and auditory modality. French and German adults performed a visual and auditory lexical decision task that involved the same translation-equivalent items. The focus of the study was on nonwords, which were constructed in a way that made it possible to…

Early and late bilinguals both differ in the speed with which they comprehend language or in their processing of sentences compared to monolinguals. This is possibly a result of cross-language interference, differential allocation of cognitive resources, or some other difference in language-dependent processes. This dissertation presents research…

Two experimental paradigms, a picture-naming task and a Stroop interference task, were employed to address the structure of the multilingual mental lexicon; more specifically, the process of multilingual non-selective lexical access. German-English-French speakers named objects in their native and most dominant language in a task that included a…

The present study investigated whether adult learners of second language (L2) can automatically activate emotional connotation during emotional word recognition as compared native (L1) users and whether L2 use plays a significant role in it. The automaticity of activation was measured through the emotional Stroop task. In this task, emotional…

Language production ultimately aims to convey meaning. Yet words differ widely in the richness and density of their semantic representations, and these differences impact conceptual and lexical processes during speech planning. Here, we replicated the recent finding that semantic richness, measured as the number of associated semantic features…

In four experiments, we investigated the impact of letter case (lower case vs. UPPER CASE) on the processing of sequences of written words. Experiment 1 used the rapid parallel visual presentation (RPVP) paradigm with postcued identification of one word in a five-word sequence. The sequence could be grammatically correct (e.g., "the boy likes…

Purpose: It is not clear if behavioral indices of listening effort are sensitive to changes in signal-to-noise ratio (SNR) for young children (7-12 years old) from multilingual backgrounds. The purpose of this study was to explore the effects of SNR on listening effort in multilingual school-aged children (native English, nonnative English) as…

Previous studies using artificial languages suggest that sentence production can be guided by verb-specific as well as verb-general statistics present in the language input. Here we investigated whether the statistical properties of ongoing input in the speakers' native language systematically affected their sentence production. Three experiments…

The Interface Hypothesis proposes that second language (L2) learners, even at highly proficient levels, often fail to integrate information at the external interfaces where grammar interacts with other cognitive systems. While much early L2 work has focused on the syntax-discourse interface or scalar implicatures at the semantics-pragmatics…

Word knowledge and the speed of word processing in monolingual children and adults are influenced by word properties, such as the age of acquisition (AoA), imageability, and frequency. Understanding how different properties of words contribute to the ease of processing by bilingual children is a critical step for establishing models of childhood…

Cognitive flexibility (switching) and control (inhibition) are among widely accepted cognitive advantages of bilingualism. Switch Cost (SC), i.e., the time difference to complete a switch versus non-switch task, is a construct for measuring the switching ability. The need to control the interference and switching between one's languages leads to…

The present study compares native and nonnative processing of Spanish active and passive sentences. The nonnative speakers were tested before and after receiving processing instruction on the Spanish passive. The native speakers were tested once and provide a baseline for comparisons. We measured accuracy and response time to select the correct…

This study examines the effects of asymmetrical mappings of L2 sounds to L1 sounds on real-time processing of L2 phonology. L1-Korean participants completed a self-paced listening (SPL) task paired with a picture verification (PV) task, in which an English sentence was presented word by word along with a picture that matched or mismatched the…
