    Facial and semantic emotional interference: A pilot study on the behavioral and cortical responses to the dual valence association task
    (2011) Hurtado León, Esteban Andrés; Ibáñez, Agustín; Riveros Miranda, Rodrigo Andrés; Urquina, Hugo.; Cardona, Juan F.; Petroni, Agustín.; Lobos-Infante, Alejandro.; Barutta, Joaquin.; Baez, Sandra.; Manes, Facundo.
    Abstract Background Integration of compatible or incompatible emotional valence and semantic information is an essential aspect of complex social interactions. A modified version of the Implicit Association Test (IAT) called Dual Valence Association Task (DVAT) was designed in order to measure conflict resolution processing from compatibility/incompatibly of semantic and facial valence. The DVAT involves two emotional valence evaluative tasks which elicits two forms of emotional compatible/incompatible associations (facial and semantic). Methods Behavioural measures and Event Related Potentials were recorded while participants performed the DVAT. Results Behavioural data showed a robust effect that distinguished compatible/incompatible tasks. The effects of valence and contextual association (between facial and semantic stimuli) showed early discrimination in N170 of faces. The LPP component was modulated by the compatibility of the DVAT. Conclusions Results suggest that DVAT is a robust paradigm for studying the emotional interference effect in the processing of simultaneous information from semantic and facial stimuli.Abstract Background Integration of compatible or incompatible emotional valence and semantic information is an essential aspect of complex social interactions.

    Potential consequences of abandonment in preschool-age: Neuropsychological findings in institutionalized children
    (HINDAWI LTD, 2012) Cardona, Juan F.; Manes, Facundo; Escobar, Josefina; Lopez, Jessica; Ibanez, Agustin
    Objective: Several longitudinal studies had shown that early deprivation and institutionalization during the first six months of life affects the emotional, cognitive, social and neurophysiologic development. Nevertheless, our understanding of possible similar effects of delayed institutionalization, in preschool-age remains unclear to this day. The goal of this study is to evaluate the cognitive performance of institutionalized children with history of preschool-age physical abandonment.
