ANTONIAZZI, Mariana; DOMENICONI, Camila  and  SCHMIDT, Andréia. Effect of object pre-exposure on exclusion performance and name-object relation learning. Acta comport. [online]. 2014, vol.22, n.1, pp. 23-36. ISSN 0188-8145.

Despite being considered one of the most robust emergent performances across Psychology of Learning, responding by exclusion seems to be influenced by variables which have been insufficiently studied. The aim of this study was to investigate the influence of object pre-exposure on the responding by exclusion and name-object learning after a single exclusion trial. Participants were ten typically developing children (27-30 months). Auditory-visual matching-to-sample tasks were conducted, using toys and a blank comparison (mask) as choice alternative. Exclusion probes were presented in two different experimental conditions: with and without pre-exposure of new object used in the probes. Data analysis indicated that object pre-exposure had a negative influence on both responding by exclusion and learning responses. The previous exposure of the object might decrease the novelty of such object and, therefore, it might increase the possibility of fusion between defined and undefined stimuli classes.
