This study was designed to explore whether the human visual system has different degrees of tolerance to character position changes for letter strings, digit strings, and symbol strings. An explicit perceptual matching task was used (same-different judgment), and participants' electrophysiological activity was recorded. Materials included trials in which(More)
In recent decades several authors have suggested that bilinguals exhibit enhanced cognitive control as compared to monolinguals and some proposals suggest that this main difference between monolinguals and bilinguals is related to bilinguals' enhanced capacity of inhibiting irrelevant information. This has led to the proposal of the so-called bilingual(More)
Language comprehension is incremental, involving the integration of information from different words together with the need to resolve conflicting cues when unexpected information occurs. The present fMRI design seeks to segregate the neuro-anatomical substrates of these two processes by comparing well-formed and ill-formed sentences during subject-verb(More)
Bilinguals have been shown to outperform monolinguals in a variety of tasks that do not tap into linguistic processes. The origin of this bilingual advantage has been questioned in recent years. While some authors argue that the reason behind this apparent advantage is bilinguals' enhanced executive functioning, inhibitory skills and/or monitoring(More)
Agreement computation is one of the pillars of language comprehension. In this fMRI study, we investigated the neuro-cognitive processes of agreement associated with number feature covariance in subject-verb agreement and determiner-noun concord in Spanish by creating mismatches (ella/*ellas corre, she/*they dances vs. el/*los anillo, thesg/*thepl ring).(More)
Results illustrating an atypical neural processing in the early and late differentiation of infant faces have been obtained with neglectful mothers. The present study explores whether a different pattern of response is observed when using non-infant affective pictures. We examined the event-related evoked potentials and induced delta, theta and alpha(More)
