Abstract： The Gamma oscillation is one kind of neural interaction activities. The characteristics of the Gamma oscillation contribute to its important role in information binding process. A large body of research has demonstrated that binding the sensory signal from multiple channels at the perceptual level is associated with the gamma oscillatory synchronization in sensory cortex (e.g. visual cortex, auditory cortex), whereas binding the information from single channel at the conscious level is associated with the enhanced Gamma oscillations in higher cortex (e.g. temporo-parietal cortex). The functions of Gamma oscillations in information-binding process have been described in several theoretical frameworks, including Neural Coupling model and Match & Utilization model. However, extreme caution should be exercised when Gamma oscillations were applied as an index of binding process. What roles of Gamma oscillations play in a complex binding process should be investigated in the future.

Abstract： The stimuli newly associated with the self are apt to gain perceptual saliency and display advantages in attentional attraction. Another line of studies demonstrated that perceptual saliency could facilitate active suppression through a top-down control. Therefore, we hypothesize that, if the WM feature is to be suppressed voluntarily, self-associated stimuli was more easily inhibited compared with other information in the visual search task. In current study, participants first completed an associating learning task to form four pairs of color-label links (e.g., green-self, blue-stranger, red and yellow-neutral). Then, they took a Working Memory-guided visual search task in which they needed to search a target shape among several items. Before searching, participants were asked to memorize a specific color, which was one of the four colors used in the learning task. They were informed that items with this cue color were distractors in the search task. After the search task, participants were asked to recall the memorized cue color. The results showed the RTs of the search task were significantly shorter when the informed distracter color was self-associated compared with when the color was stranger-associated or neutral, no significant difference in searching time between stranger-associated color and neural color condition. Analyses of search accuracy and memory accuracy also revealed no significant difference across conditions. These results conformed the facilitation of search performance when the known distracters were in previously link to self, participants could inhibit the distracters more easily and search target more rapidly. To summarize, although valuable objects such as self-relevant information are attractive in nature, people often encounter situations where they would prefer to aviod such distraction while focusing on the task goal. The present study confirmed our hypothesis that the self-associated information was actively suppressed more easily and thus enhanced participants’ performance in visual research. These findings demonstrate a flexible role of learned self association on cognitive control.

Abstract： Stimuli related to the self are processed more efficiently in a variety of cognitive tasks. Recent studies have shown that this self-referential bias is modulated by one’s emotional states; however, it remains unclear whether the impact of emotion is primarily attributable to valence or arousal. Experiment 1 measured the self-prioritization effect with a label-shape matching task under four mood states. The results revealed a stronger self-prioritization effect in moods of higher arousal level, and a significant correlation between the arousal ratings and the self-prioritization effect. Experiment 2 further showed that alerting cues, which have been known to elevate the arousal level, boosted the self-prioritization effect measured in a similar label-shape matching task. These results provide clear evidence that arousal modulates self-referential processing
