| Résumé : | Attentional biases linked to emotional stimuli were investigated in healthy people using an auditory adaptation of the cueing paradigm. Specifically, we investigated whether both validity effects elicited by predictive, endogenous cues and the Inhibition of Return phenomenon (IOR; Posner & Cohen, 1984) elicited by unpredictive, exogenous cues are influenced by the emotional content of spoken words. Supporting the idea that exogenous orienting is not an encapsulated phenomenon (Stolz, 1996), we found abolished IOR for negative words (Experiments 3 and 4). Thus, attention would not be prevented from returning to the previously explored location of a negative word. On the contrary, no emotional modulation of the validity effects was observed (Experiments 1 and 2), suggesting that the intervention of resource-demanding orienting strategies increased cognitive load and thus prevented any emotional modulation. Still, facilitative, nonspatial effects of negative words were found when initial attentional shifts elicited by the cue were both exogenous and endogenous (Experiment 1), but not when they were exclusively endogenous (Experiment 2). These results highlight the importance of both the negativity of a stimulus and the automaticity of attentional shifts in eliciting spatial and nonspatial attentional effects. |
