Resumo: In the present study, we investigated whether emotional pictures, presented as distractors, interfere in the performance of a competing neutral task. The participants had to discriminate the orientation of two bars presented bilaterally in the periphery (similar or dissimilar). Task difficulty was determined by the differences in orientation between the bars: the smallest orientation differences were used in the hardest task. Simultaneously, either neutral (people) or unpleasant (mutilated) pictures were presented centrally between the two bars. We observed that negative pictures interfere in the performance even in the harder task - the more attention demanding one. When the recognition of those pictures was tested, an advantage for the negative pictures was observed. These results showed that emotional stimuli are still processed even when the attentional load of a concurrent task is high. It is possible that those stimuli are potent drivers of privileged processing and can not be easily ignored.

No presente estudo investigamos se estímulos emocionais distrativos são capazes de interferir na realização de tarefas nas quais é exigido um alto engajamento da atenção. Para tanto foi realizado um teste de discriminação de orientação entre duas barras apresentadas bilateralmente na periferia do campo visual (julgamento igual ou diferente). O grau de dificuldade da tarefa dependia da diferença de orientação das mesmas. Simultaneamente era apresentada uma figura central (neutra ou negativa) entre as barras. Foi observado que as figuras negativas interferiram no desempenho dos voluntários mesmo na tarefa mais difícil, que exigia maior engajamento atencional. Além disto, quando o reconhecimento posterior destas figuras era testado, figuras negativas eram mais lembradas do que neutras. Estes dados sugerem que estímulos emocionais são privilegiados na disputa por recursos de atenção. É possível que esse privilégio ocorra devido a relevância destes estímulos, sendo dificilmente ignorados. Universidade de São Paulo.
