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…

Semantic and phonological similarity effects provide critical constraints on the mechanisms underlying language production. In the present study, we jointly investigated effects of semantic and phonological similarity using the continuous naming task. In the semantic condition, Chinese Mandarin speakers named a list of pictures composed of 12…

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…

Studies on agreement production consistently report an increase in production errors in the presence of an attractor mismatching the agreement feature of the target. In contrast, results from comprehension studies are mixed, ranging from lack of effect to facilitation. We report 2 forced-choice experiments and 2 self-paced reading experiments on…

We investigated whether bilinguals' integration of a code-switch during real-time comprehension, which involves resolving among conflicting linguistic representations, modulates the deployment of cognitive-control mechanisms. In the current experiment, Spanish-English bilinguals (N = 48) completed a cross-task conflict-adaptation paradigm that…

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…

Previous studies on spoken word production have shown that native English speakers used phoneme-sized units (e.g., a word-initial phoneme, C) to produce English words, and native Mandarin Chinese speakers employed syllable-sized units (e.g., a word-initial consonant and vowel, CV) as phonological encoding units in Chinese. With spoken word…

The present study examines when second language (L2) learners read words in the L2, whether the orthography and/or phonology of the translation words in the first language (L1) is activated and whether the patterns would be modulated by the proficiency in the L2. In two experiments, two groups of Chinese learners of English immersed in the L1…

The present behavioral study aimed to examine the impact of language control expertise on two domain-general control processes, i.e. active inhibition of competing representations and overcoming of inhibition. We compared how Simultaneous Interpreters (SI) and Highly Proficient Bilinguals--two groups assumed to differ in language control…

According to some accounts, the bilingual advantage is most pronounced in the domain of executive attention rather than inhibition and should therefore be more easily detected in conflict adaptation paradigms than in simple interference paradigms. We tested this idea using two conflict adaptation paradigms, one that elicits a list-wide…

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…

Agreement is a covariation in morphological form that reflects relations between words. A series of experiments were carried out in Italian during production and comprehension where an element interferes with agreement. The likelihood of interference found in both modalities is related to the markedness of the intervener and to its grammatical…

This study examined how language proficiency and age of acquisition affect a bilingual language user's reliance on the dominant language during lexical access. Two bilingual groups performed a translation recognition task: Mandarin-English classroom bilinguals who acquired their dominant language (Mandarin) from birth and their non-dominant…

Purpose: This study examines 3 hypotheses about the processing of "wh"-questions in both neurologically healthy adults and adults with Broca's aphasia. Method: We used an eye tracking while listening method with 32 unimpaired participants (Experiment 1) and 8 participants with Broca's aphasia (Experiment 2). Accuracy, response time, and…

This study examines second language activation in Arabic-English bilinguals for whom Arabic was the first language. Modeling its design on Colome (2001), the research compared processing in a picture-phoneme matching task for Arabic-English bilinguals tested in the United States or in Saudi Arabia to determine whether activation of English…
