Visual attention and visual working memory (VWM) are two major cognitive functions in humans, and they have much in common. A growing body of research has investigated the effect of emotional information on visual attention and VWM. Interestingly, contradictory findings have supported both a negative bias and a positive bias toward emotional faces (e.g., angry faces or happy faces) in the attention and VWM fields. We found that the classical paradigms—that is, the visual search paradigm in attention and the change detection paradigm in VWM—are considerably similar. The settings of these paradigms could therefore be responsible for the contradictory results. In this paper, we compare previous controversial results from behavioral and neuroscience studies using these two paradigms. We suggest three possible contributing factors that have significant impacts on the contradictory conclusions regarding different emotional bias effects; these factors are stimulus choice, experimental setting, and cognitive process. We also propose new research directions and guidelines for future studies. ...

Here, we tested whether an attentional ...
The impact of visual working memory capacity on the filtering efficiency of emotional face distractors Ye, Chaoxiong; Xu, Qianru; Liu, Qiang; Cong, Fengyu; Saariluoma, Pertti; Ristaniemi, Tapani; Astikainen, Piia (Elsevier B.V., 2018)Emotional faces can serve as distractors for visual working memory (VWM) tasks. An event-related potential called contralateral delay activity (CDA) can measure the filtering efficiency of face distractors. Previous ...
Zhang, Yin; Ye, Chaoxiong; Roberson, Debi; Zhao, Guang; Xue, Chengbo; Liu, Qiang (Sage Publications Ltd., 2018)Previous research has demonstrated that visual working memory performance is better when visual items are allocated in both left and right visual fields than within only one hemifield. This phenomenon is called the bilateral ...
Individual differences in working memory capacity are unrelated to the magnitudes of retrocue benefits Ye, Chaoxiong; Xu, Qianru; Liu, Xinyang; Astikainen, Piia; Zhu, Yongjie; Hu, Zhonghua; Liu, Qiang (Nature Publishing Group, 2021)Previous studies have associated visual working memory (VWM) capacity with the use of internal attention. Retrocues, which direct internal attention to a particular object or feature dimension, can improve VWM performance ...
