Effects of emotion-induced self-focused attention on item and source memory

The relationship between risk perception of COVID-19 and willingness to help: A moderated mediation model

Previous studies have revealed that situational risk factors have a significant influence on the willingness to help. Amidst the COVID-19 pandemic, maybe risk perception of COVID-19 is also correlated to the willingness to help. This study examined the mediating effect of interpersonal alienation and the moderating effect of cognitive reappraisal and expressive suppression in the relationship between risk perception of COVID-19 and willingness to help. Data from a large sample of Chinese college students (N = 2, 163) completed the measures of risk perception of COVID-19, willingness to help, interpersonal alienation, emotion regulation strategies including cognitive reappraisal and expressive suppression. The results indicated that the risk perception of COVID-19 negatively correlated to willingness to help. Interpersonal alienation partially mediated the link between risk perception of COVID-19 and willingness to help. College students' expressive suppression moderated the associations between interpersonal alienation and willingness to help. And who adopted more expressive suppression, the connection between interpersonal alienation and willingness to help was weaker compared to students who reported less expressive suppression. But cognitive reappraisal did not moderate the relationship between risk perception of COVID-19 and interpersonal alienation. Implications of the present paper for theory and practice are discussed.

Effect of the congruity of emotional contexts at encoding on source memory: Evidence from ERPs

Emotion's influence on source memory has proven more elusive and the lack of studies investigates the effect of the congruent emotional contexts on source memory. Here, we investigated these issues using event-related potentials (ERPs) to assess emotional-induced neural correlates. During encoding, congruent word-picture (a word 'shoes' - a picture described shoes) and incongruent word-picture (a word 'pepper' - a picture described shoes) with a prompt (Common? or Natural?) were presented. At retrieval, participants indicated which prompts were concomitantly presented with the word during encoding. Behavioral results revealed that source memory accuracy was enhanced in the neutral contexts compared to the negative contexts, and enhanced in the incongruent condition relative to the congruent condition, suggesting that emotional contexts impaired source memory performance, and incongruent information enhanced source memory. ERPs results showed that early P2 old/new effect (150-250 ms) and FN400 old/new effect (300-450 ms) were observed for words with correct source that had been encoded in the congruent emotional contexts, and that a larger parietal old/new effect, between 500 and 700 ms, was observed for words with correct source that had been encoded in the incongruent condition than in the congruent condition, irrespective the nature of context. The ERPs results indicate that retrieval of source details for the associated emotionally congruent information supports the idea that emotional events could attract more attentional resources, and reflects the contribution of familiarity-based process. Meanwhile, retrieval of source details for the associated incongruent information reflects a stronger contribution of recollection-based process.

Self-awareness buffers the consequences of negative feedback: Evidence from an ERP study

Previous studies have found that self-awareness can help people to recruit more cognitive resources, while people with more cognitive resources can better buffer the detrimental effects of negative events. However, it is not clear whether self-awareness can directly buffer the consequences of negative feedback (i.e., reducing neural sensitivity to negative feedback). To explore this issue, we used a scrambled sentence task (SST) to manipulate participants' self-awareness (self vs. other) and investigated whether outcome evaluations in a gambling task are modulated by the self-awareness priming. Event-related brain potentials (ERPs) were recorded while 27 normal adults performed a gambling task. The ERP analysis focused on the feedback-related negativity (FRN), reward positivity (RewP) and P300 component. We found that the self-awareness priming resulted in a smaller FRN response to the losses compared with the other-awareness priming. There was no significant difference in the RewP response to wins between the self-awareness condition and the other-awareness condition. We also found that the self-awareness condition evoked larger P300 amplitude than the other-awareness condition. The present findings suggest that self-awareness can help people to cope with negative feedback in the early semiautomatic outcome evaluation stage (i.e., reducing neural sensitivity to negative feedback) and enhance top-down evaluation to both positive and negative feedback in the late and deliberate stage, providing direct evidence of the adaptive function of self-awareness on outcome experience.
