RESUMO
The current investigation, framed within the emotional cognitive science field, was conducted with three patients with major depression. They participated in a therapeutic process which involved EMDR (Eye Movement Desensitization and Reprocessing). Data were obtained in the clinical practice through a longitudinal one subject study design, including: emotional valence identification within affective priming experiments; and depressive emotional representation studies, the data of which was analyzed using multidimensional scaling. The first ones had the purpose of observing the therapeutic impact over the emotional cognitive bias mechanism regarding depresogenic words related to traumatic experiences; and the second, to analyze modifications on depressive schemata. The results showed that EMDR had a positive effect both on emotional cognitive processing and on long-term memory conceptual organization. In the discussion section, interesting remarks are made on the incorporation of emotional cognitive science tools to the EMDR clinical practice.
