title: Facial and semantic emotional interference: a pilot study on the behavioral and cortical responses to the Dual Valence Association Task.
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.
