Attentional boost effect: research based on source memory and emotional materials.

The attentional boost effect (ABE) refers to the phenomenon that stimuli which appear with targets in a detection task are better remembered than those that appear with distractors. Previous studies have consistently reported a robust ABE in item memory, but inconsistent conclusions have been drawn for source memory. Additionally, regarding the impact of emotional stimuli on the ABE, conclusions have also been inconsistent.

Effects of cognitive reappraisal on directed forgetting of negative emotional memory: an ERP study.

This study aimed to adopt the item-method directed forgetting (DF) paradigm to explore the effects of cognitive reappraisal on intentional forgetting of negative emotional pictures. Behavioral results showed that the recognition of to-be-forgotten but remembered (TBF-r) was significantly greater than that of to-be-remembered and remembered (TBR-r) in the recognition test, which was the opposite result to the DF effect. Event-related potential (ERP) results showed that in the 450-660 ms (ms) of cue presentation, the F-cue of the cognitive reappraisal condition (imagining the upcoming pictures to be "fake or performed by actors" to avoid or reduce the intensity of negative emotions caused by the pictures) elicited more positive late positive potential (LPP) than passive viewing (participants watched freely and paid attention to the characters, scenes, and other details in the picture).

The relationship between adolescent risk perception and emotions during the COVID-19: a short-term longitudinal study.

This study explores the relationship between adolescents' perceptions of epidemic risk and their emotions through three follow-up surveys during the early stages of the COVID-19 pandemic on February 11th (T1), 18th (T2), and 25th (T3), 2020. Three hundred and four adolescents in different academic stages (junior high middle school, senior high middle school, and university) participated in the online survey, and cross-lag analysis was used to examine the causal relationship between epidemic risk perceptions and positive and negative emotions. The results found that the individual's positive emotions were significantly higher than the negative emotions in T1, T2 and T3.

Effects of Intergroup Vicarious Ostracism on Individual Prejudicial Attributions and Aggressive Intentions.

This study explores the effects of intergroup vicarious ostracism on individual prejudicial attributions and aggressive intentions. It takes Tibetan and Hui college students in northwestern China as participants. Study 1 and Study 2 explore the difference in observers' prejudicial attributions and aggressive intentions, respectively, when the group members who experienced ostracism (Tibetan college students) observed an in-group member being ostracized by out-group members versus an in-group member being ostracized by in-group members.
