Is the bilingual language production system a dynamic system that can operate in different language activation states? Three experiments investigated to what extent cross-language phonological co-activation effects in language production are sensitive to the composition of the stimulus list. L1 Dutch-L2 English bilinguals decided whether or not a…

Classifier languages are spoken by a large portion of the world's population, but psychologists have only recently begun to investigate the psychological reality of classifier categories and their potential for influencing non-linguistic thought. The current work evaluates both the mental representation of classifiers and potential cognitive…

Masked affix priming effects have usually been obtained for words sharing the initial affix (e.g., "reaction"-"REFORM"). However, prior evidence on masked suffix priming effects (e.g., "baker"-"WALKER") is inconclusive. In the present series of masked priming lexical decision experiments, a target word was…

Recent research in psychology and neuroscience has demonstrated that co-speech gestures are semantically integrated with speech during language comprehension and development. The present study explored whether gestures also play a role in language learning in adults. In Experiment 1, we exposed adults to a brief training session presenting novel…

Category-specific disorders are frequently explained by suggesting that living and non-living things are processed in separate subsystems (e.g. Caramazza & Shelton, 1998). If subsystems exist, there should be benefits for normal processing, beyond the influence of structural similarity. However, no previous study has separated the relative…

Simple name-retrieval models of spoken word planning (Bloem & La Heij, 2003; Starreveld & La Heij, 1996) maintain (1) that there are two levels in word planning, a conceptual and a lexical phonological level, and (2) that planning a word in both object naming and oral reading involves the selection of a lexical phonological representation.…
