摘　　要：嗅觉与情绪、认知等心理活动密切相关。研究采用事件相关电位技术,探索气味影响创造性观点评价的效应及神经关联。要求个体在三种气味(薰衣草、迷迭香、无味空气)条件下对一系列创造性观点的新颖性进行评价。行为结果显示,迷迭香显著提高个体对低新颖度观点的主观新颖性评分,但气味并非通过情绪中介来影响观点评价。脑电结果显示,在空气和薰衣草条件下,高新颖度观点引发最大的N400振幅;在迷迭香条件下,中新颖度观点引发最大的N400效应。迷迭香和空气条件下的晚期正成分振幅在额叶和顶叶区存在显著差异。上述结果表明,在创造性观点评价时,迷迭香能够调节大脑对新颖信息的认知加工活动,从而提高个体对低创造性观点的新颖性评价。Olfaction serves as a critical channel through which humans interact with their environment.Extensive research has explored the effects of odors on psychological phenomena,including emotion,memory,and decision-making.However,its impact on creative thinking,particularly during the evaluation phase,remains underexplored.The evaluation of creative ideas is a pivotal stage in creative thinking,and understanding the role of odors may provide insights into how environmental factors may enhance creativity.This study aims to fill this gap by using Event-Related Potentials(ERPs)to investigate how odors influence the evaluation of creative ideas and the associated neurophysiological mechanisms.Among natural odors,lavender and rosemary have been extensively studied for their psychological and physiological effects.Lavender is widely recognized for its relaxing properties,while rosemary is known to enhance alertness.In this study,these two odors were selected as olfactory stimuli to examine their different effects on creativity evaluation.A 3(odors:air,rosemary,lavender)×3(novelty of ideas:low novelty,medium novelty,high novelty)mixed design was conducted:odors served as a between-subjects variable,while novelty of ideas served as a within-subjects variable.Ninety-one participants were randomly assigned to one of three conditions:Air(n=30),Rosemary(n=31),and Lavender(n=30).Odors,derived from pure essential oils,were delivered via the Sniff-0 portable scent controller(CyNexo srl,Italy).Participants were asked to complete the Self-Assessment Manikin scale to measure the valence and arousal of their emotional states before and after the creative evaluation task.During the task,they rated the originality of ideas from three novelty levels(low,medium,and high).Brain activity was recorded using electroencephalography(EEG)during the evaluation process,and ERP data were analyzed to explore the neurophysiological correlates of odor-induced creativity modulation.The behavioral results revealed a significant interaction between odors
