Resumo: | The emotional nature of a facial expression seems to favour a bias regarding the perception of its duration. In this paper we present a study that tests the hypothesis that this effect will be moderated by the emotional dimensions of facial expressions (valence and arousal), addressing its explanation in terms of processes that interfere with the functioning of an “internal clock”, including activation and attentional processes. Using a temporal bisection task with duration between 400 and 1600 ms, the results suggest a valence effect: The duration of the negative faces is overestimated in relation to positive faces. This effect was moderated by the intensity of emotional expressions (arousal), but only in the low arousal condition. In the high arousal condition positive and negative faces were identically estimated. The fact that this interaction has been found only in short time windows, suggests a concurrent interference of activation and attentional processes. This explanation is discussed in the article, taking into account its limitations. DOI: http://dx.doi.org/10.17575/rpsicol.v24i2.305 |

DOI: http://dx.doi.org/10.17575/rpsicol.v24i2.305A natureza emocional de uma expressão facial parece enviesar a percepção da sua duração. Neste artigo apresentamos um estudo que testa a hipótese deste efeito ser moderado pelas dimensões emocionais (valência e arousal) abordando a sua explicação em termos de processos que interferem com o funcionamento de um “relógio interno”, nomeadamente processos atencionais e activacionais. Utilizando uma tarefa de bissecção temporal com durações entre 400 e 1600 ms, os resultados sugerem um efeito da valência da emoção expressa por uma face: a duração das faces negativas é sobre-estimada relativamente às positivas. Este efeito foi moderado pela intensidade das expressões emocionais (activação [arousal]) verificando-se apenas claramente na condição de baixa intensidade. Na condição de elevada intensidade, as faces positivas foram avaliadas de forma idêntica as negativas. O facto de esta interacção apenas se verificar em durações mais curtas, sugere-nos uma interferência concorrente de processos atencionais e activacionais. Esta explicação é discutida no artigo, tendo em consideração as suas limitações.

The emotional nature of a facial expression seems to favour a bias regarding the perception of its duration. In this paper we present a study that tests the hypothesis that this effect will be moderated by the emotional dimensions of facial expressions (valence and arousal), addressing its explanation in terms of processes that interfere with the functioning of an “internal clock”, including activation and attentional processes. Using a temporal bisection task with duration between 400 and 1600 ms, the results suggest a valence effect: The duration of the negative faces is overestimated in relation to positive faces. This effect was moderated by the intensity of emotional expressions (arousal), but only in the low arousal condition. In the high arousal condition positive and negative faces were identically estimated. The fact that this interaction has been found only in short time windows, suggests a concurrent interference of activation and attentional processes. This explanation is discussed in the article, taking into account its limitations. DOI: http://dx.doi.org/10.17575/rpsicol.v24i2.305 |
