Abstract

The priming of affective stimuli influences the subsequent emotional and cognitive processes. Though the affective priming effect has been widely discussed at the behavioral level, systematic reviews, and evaluations of the electrophysiological data in affective priming studies remain scarce, with findings across various research appearing inconsistent. By adopting a three-level random-effects meta-analytic approach, the present study aimed to quantitatively synthesize the event-related potential (ERP) evidence of the affective priming effect on N400 and late positive potential (LPP) components. We identified 47 studies through a search of four databases (i.e., Web of Science, PubMed, ProQuest, and PsycINFO). Meta-analysis of the N400 component in N = 1118 participants and the LPP component in N = 804 participants both indicated that affectively incongruent prime-target trials induced larger ERP amplitudes compared to affectively congruent prime-target trials, with d_N400 = 0.63 (95% CI: 0.38, 0.88; SE = 0.13; t = 5.03; p < 0.001), d_LPP = 0.24 (95% CI: 0.03, 0.46; SE = 0.11; t = 2.29; p < 0.05), respectively. Moderator analyses showed that stimulus onset asynchrony (SOA) and task demand have explained the variations in the N400 effect and the LPP effect is moderated by SOA. Potential explanations, limitations, and future research directions were discussed.

情感启动对N400和LPP成分的影响：一个三水平元分析。

情感刺激的启动影响随后的情绪和认知过程。尽管情感启动效应在行为层面上得到了广泛的讨论，但对情感启动研究中电生理数据的系统回顾和评估仍然很少，各种研究的结果似乎不一致。本研究采用三水平随机效应荟萃分析方法，旨在定量综合情感启动效应对N400和晚期正电位（LPP）成分的事件相关电位（ERP）证据。我们通过搜索四个数据库（即Web of Science、PubMed、ProQuest和PsycINFO）确定了47项研究。对N = 1118名被试的N400分量和N = 804名被试的LPP分量的meta分析均表明，与N = 804名被试的LPP分量相比，情绪不一致的启动目标试验诱发的ERP振幅更大，dN400 = 0.63 (95% CI: 0.38, 0.88; SE = 0.13; t = 5.03; p LPP = 0.24 (95% CI: 0.03, 0.46; SE = 0.11; t = 2.29

期刊介绍： Founded in 1964, Psychophysiology is the most established journal in the world specifically dedicated to the dissemination of psychophysiological science. The journal continues to play a key role in advancing human neuroscience in its many forms and methodologies (including central and peripheral measures), covering research on the interrelationships between the physiological and psychological aspects of brain and behavior. Typically, studies published in Psychophysiology include psychological independent variables and noninvasive physiological dependent variables (hemodynamic, optical, and electromagnetic brain imaging and/or peripheral measures such as respiratory sinus arrhythmia, electromyography, pupillography, and many others). The majority of studies published in the journal involve human participants, but work using animal models of such phenomena is occasionally published. Psychophysiology welcomes submissions on new theoretical, empirical, and methodological advances in: cognitive, affective, clinical and social neuroscience, psychopathology and psychiatry, health science and behavioral medicine, and biomedical engineering. The journal publishes theoretical papers, evaluative reviews of literature, empirical papers, and methodological papers, with submissions welcome from scientists in any fields mentioned above.
