Peer reviewed Peer reviewed

Cano, Agnes; Hernandez, Mireia; Ivanova, Iva; Juncadella, Montserrat; Gascon-Bayarri, Jordi; Rene, Ramon; Costa, Albert – Brain and Language, 2010
We report the naming performance of a Spanish patient (AQF) suffering from Primary Progressive Aphasia (PPA). AQF's performance revealed a grammatical category-specific deficit, with poorer performance in verb than in noun naming. Furthermore, this dissociation was only present in written naming. Importantly, the patient's dissociation between…

Hernandez, Mireia; Cano, Agnes; Costa, Albert; Sebastian-Galles, Nuria; Juncadella, Montserrat; Gascon-Bayarri, Jordi – Brain and Language, 2008
We report the naming performance of an early and highly proficient Spanish-Catalan bilingual (JPG) suffering from Primary Progressive Aphasia (PPA). JPG's performance revealed a grammatical category-specific deficit, with worse performance in naming verbs than nouns. This dissociation was present in oral and written naming and in his two…

A Further Look at Semantic Context Effects in Language Production: The Role of Response Congruency
Peer reviewed Peer reviewed

Kuipers, Jan-Rouke; La Heij, Wido; Costa, Albert – Language and Cognitive Processes, 2006
Most current models of speech production predict interference from related context words in picture-naming tasks. However, Glaser and Dungelhoff (1984) reported semantic facilitation when the task was changed from basic-level naming to category-level naming. The authors explore two proposals to account for this change in polarity of the semantic…

How Do Highly Proficient Bilinguals Control Their Lexicalization Process? Inhibitory and Language-Specific Selection Mechanisms are Both Functional
Peer reviewed Peer reviewed

Costa, Albert; Santesteban, Mikel; Ivanova, Iva – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2006
The authors report 4 experiments exploring the language-switching performance of highly proficient bilinguals in a picture-naming task. In Experiment 1, they tested the impact of language similarity and age of 2nd language acquisition on the language-switching performance of highly proficient bilinguals. Experiments 2, 3, and 4 assessed the…

Spoonish Spanerisms: A Lexical Bias Effect in Spanish
Peer reviewed Peer reviewed

Hartsuiker, Robert J.; Anton-Mendez, Ines; Roelstraete, Bjorn; Costa, Albert – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2006
Lexical bias is the tendency for phonological errors to form existing words at a rate above chance. This effect has been observed in experiments and corpus analyses in Germanic languages, but S. del Viso, J. M. Igoa, and J. E. Garcia-Albea (1991) found no effect in a Spanish corpus study. Because lexical bias plays an important role in the debate…
