Abstract： In visual search, the phenomenon that attention is attracted by task-independent salient stimulus, which leads to search efficiency reduction is called attentional capture. In the traditional theories of visual attentional capture, stimulus-driven theory and goal-driven theory were argued for nearly 20 years. According to stimulus-driven theory, attention is automatically captured by physically salient objects, and regardless of the intentions of the observers. Other researchers believe that only stimuli that match the features of the search target will capture attention. In recent years, two new hybrid models were proposed, which combined bottom-up capture and top-down control settings, called rapid disengagement hypothesis and signal suppression hypothesis. The main content of the rapid disengagement hypothesis is that a salient distractor can always capture attention in a bottom-up manner, but attention only landed on the position of the highlighted stimulus that similar to the target. If the selected stimulus does not look like the target at all, disengagement from that location would be fast and swift. In the empirical evidences of the rapid disengagement hypothesis, spatial-cueing paradigm and oculomotor disengagement paradigm were most often adopted. In those tasks, participants usually took a singleton search strategy to promote search. The signal suppression hypothesis posits that a salient object can automatically produce a bottom-up “attend-to-me” signal, but this signal can be suppressed via top-down control processes when the highlighted object does not meet the task requirements. In the empirical evidences of the signal suppression hypothesis, an additional singleton paradigm was most often adopted. In those tasks, participants were forced to take a feature search strategy. The rapid disengagement hypothesis and the signal suppression hypothesis are indispensable components of the theories of attentional capture, and there are both similarities and differences between them. The similarity lies in the fact that both two theories assume that the initial stage of the attention capture occurs automatically. However, there are different opinions about the shifting of attention during this initial stage. The rapid disengagement hypothesis holds that there is an attention shift in the initial stage of the processing of the salient stimulus, and when the attention has enough time to disengage from the highlight stimulus that does not match the target, attentional capture will not occur. Different from the above views, the signal suppression hypothesis believes that there is no attention shift in the initial stage of the highlight stimulus processing. Attention capture does not actually occur because the salience signal can be suppressed by a top-down mechanism when the salient stimulus is inconsistent with the target. Future researches would focus on the following aspects: (1) More studies adopting different stimuli and experimental methods are needed to support rapid disengagement hypothesis and signal suppression hypothesis; (2) The effects of reward and training on “attentional capture-disengagement” and “signal-suppression” should also be explored in future researches; (3) The neural bases of reactive inhibition mechanism and active inhibition mechanism that involved in rapid disengagement hypothesis and signal suppression hypothesis is a problem which deserves attention.

Abstract： Both inhibition of return (IOR) and emotion have the characteristics of attentional bias and improving search efficiency. Previous studies mostly used a single modality presentation of emotional stimuli to investigate the relationship between the two, but the findings are inconsistent. Existing studies have shown that the congruent emotion of audiovisual dual modality can be integrated into the perceptual stage, which is the same as the processing stage of IOR. Therefore, the present study adopted the cue-target paradigm and used audiovisual dual modality to present emotional stimuli to further investigate the interaction between emotion and IOR. Experiment 1 was a three-factor within-subject design. We manipulated the presentation of cue validity (cued vs. uncued), target modalities (visual vs. audiovisual), and emotion type (negative vs. neutral). The task of the subjects was to identify the emotional stimuli of visual modality. Experiment 2 was similar to Experiment 1, but the emotional congruency was changed. The audiovisual dual modality presented incongruent emotional stimuli (visual negative face-auditory neutral sound; visual neutral face-auditory negative sound) to further investigate whether the impact of the audiovisual dual modality emotional stimulus on IOR was caused by the emotional stimulus of the auditory modality, that is, whether the emotional stimulus of the auditory modality was processed. In Experiment 1, the responses in the cued condition were slower than those in the uncued condition, which suggested that IOR occurred. More importantly, the interaction between emotion type and cue validity in the audiovisual dual modality condition showed that congruent negative emotion produces a smaller IOR effect (11 ms) than neutral emotion (25 ms). At the same time, the audiovisual dual modality condition produced a smaller IOR effect (18 ms) than the visual single modality condition (40 ms). We also found a larger multisensory response enhancement effect in the congruent negative emotion than in the neutral emotion. In Experiment 2, the results showed that there was no interaction between emotion and IOR under the condition of audiovisual dual modality, and there was no significant difference in IOR effect between single modality and audiovisual dual modality. This indicated that the IOR effect was not influenced by the presence of incongruent emotion in the audiovisual dual modality. In summary, the present study showed that the IOR effect was influenced only when the audiovisual dual modality presented the same emotion. Our findings revealed that IOR and audiovisual dual modality congruent emotion in the same processing stage had a mutual influence. Audiovisual dual modality congruent emotion weakened the IOR effect, and the differences between the negative emotion and the neutral emotion showed the adaptability of IOR. At the same time, this study further supports the perceptual inhibition theory of IOR.
