本研究旨在考察偶像崇拜是否会导致粉丝认知中自我与偶像概念的重叠和偶 像优势效应的出现，以及这种重叠的行为相关。以往关于偶像崇拜的研究主要使 用问卷调查法，但现有量表皆存在一定缺陷，难以真实反映粉丝的卷入程度。此 外，现有研究对象集中于青少年，但由于青少年自我构念的特殊性，研究结果无 法代表所有粉丝。本研究通过问卷调查法和行为实验法相结合的方式，以成年粉 丝被试作为研究对象，检验了粉丝认知中的自我-偶像重叠和偶像优势效应的存在。研究 1 初步考察个体主观感受到的自我-偶像和自我-他人重叠程度。结果发现， 粉丝主观报告的自我中对偶像的包含程度高于他人，证明了粉丝的自我与偶像概 念存在较他人更高的重叠程度。研究 2 旨在检验偶像优势效应在知觉层面是否存 在。结果发现，偶像优势效应在知觉层面存在，粉丝组对偶像配对的反应正确率 和反应时均显著优于他人配对，非粉丝组不存在此现象，验证了粉丝自我对偶像 相关信息存在知觉层面上的处理偏好。研究 3 使用自我参照效应的 R/K 范式探讨 粉丝对偶像是否存在自我参照效应。实验结果表明，偶像优势效应在记忆层面存 在，粉丝对偶像参照信息表现出了相较于他人参照信息显著更高的总再认正确率， 也就是说，粉丝个体对偶像概念的加工深度相较他人更深。研究 4 采用知觉匹配 任务范式再次确认偶像优势效应的稳健性，并使用 5 个不同的心理测量表探索自 我-偶像重叠的行为相关。实验结果表明，偶像优势效应在知觉层面存在，并与偶 像崇拜的部分维度、生活满意度和开放性人格特质之间存在显著正相关。本研究的理论意义在于提供了一个从知觉和记忆的角度区分粉丝与非粉丝的 方法，解决了 CAS 量表现存的问题。本研究的现实贡献在于将粉丝自我中对偶像 的包含程度与追星行为和病理性指标联系起来进行了探讨，一方面可以促进粉丝 经济的增长和娱乐市场的发展，另一方面也为表现出了病理性症状的极端粉丝的 临床干预提供了思路。

As fan culture evolves, fandom is no longer “just a form of entertainment, but also a powerful cultural phenomenon that shapes the way people understand and interact with the world around them” (Jenkins, 1992). The unflinching loyalty and unwavering devotion of fans to their idols is oftentimes accompanied by selflessness. This raises a pertinent question: What motivates fans to demonstrate such wholehearted dedication towards individuals whom they have never met? Moreover, is this selflessness indicative of a symbiotic relationship between fans and their idols, wherein fans‘ self-concepts become inextricably overlapped with those of their idols?This study aimed to examine whether celebrity worship leads to increased self-idol overlap in fan cognition, thus facilitating the integration of self and idol concepts. In addition, the study also explored the possible effects of self-idol overlap on fan behavior while investigating how self-idol overlap relates to one‘s personality and psychological states, including subjective well-being, level of celebrity worship, Big Five personality traits, and self-esteem.Previous studies on celebrity worship have predominantly relied on questionnaires to assess the level of celebrity worship and the extent to which fans integrate idols into their self-concept. However, none of the existing scales could truthfully reflect the actual degree of inclusion of idols in fans‘ selves. Furthermore, most existing studies have focused on the idolatrous behavior of adolescent fans. Nevertheless, as adolescents‘ self-construal differs from that of adults, conclusions obtained from adolescent fans cannot adequately represent adult fans, who occupy a more significant proportion of the fan population and possess greater economic and temporal autonomy. To address these gaps, this study investigated the relationship between fan selves and idols by combining self-report methodology and behavioral experiments. This study employed the perceptual matching task paradigm and the R/K paradigm of self-reference effects to validate the degree of idols‘ integration into adult fans‘ selves. Subsequently, self-report questionnaires were utilized to explore the extent of self-idol overlap and the associated psychological states and personality traits of the participants, including the Celebrity Worship Scale (CAS), Subjective Well-Being Scale (SWB), Big Five Personality Inventory (BF-PI-15), and Self-Esteem Scale (SES). Integrating these methodological approaches allowed for more pertinent and generalizable findings. The current study used adult fans as study subjects to investigate whether there is an overlap between fans‘ self-concepts and their idol. Specifically, the study examined the existence of self-idol overlap at perceptual and memory levels, respectively, using explicit and implicit measures. The study showed that adult fans reported a higher degree of self-idol inclusion than self-other inclusion (Study 1). In addition, the idol-prioritization effect was evident across four experiments at both perceptual and memory levels. In the perceptual matching task, a substantial advantage for idol-labelled pairs was observed in the experimental group‘s average accuracy (Study 2 & 4) and response time (Study 4) relative to the control group. In the self-reference task, participants performed significantly higher recall scores on idol-related information than other-related information (Study 3). Moreover, correlation studies proved that the degree of self-idol overlap was significantly and positively correlated with the scores on the overall CAS, all five dimensions of CAS, the Satisfaction With Life Scale, and the agreeableness and conscientiousness dimensions of the BF-PI-15. Adult fans‘ annual spending on idols was also significantly and positively associated with their overall CAS scores, SWB scores and Positive and Negative Affect Scale but negatively related to the neuroticism dimension in the Big Five personality model.The present study holds significant theoretical and practical implications. Theoretically, it distinguishes between fans and non-fans based on the prioritization of perceptual and memory processing, which addresses the existing issue of CAS. Furthermore, this study introduces an experimental psychological paradigm that can be drawn on for future research in the classic topic of hero worship in cultural psychology. Practically, this study examines the extent to which fans include their idols in their self-concept in relation to their behavior of worshiping celebrities and pathological indicators. Such an investigation is valuable to expanding the fan economy and developing the entertainment market. Additionally, this study has potential implications for clinical interventions targeting extreme fans who exhibit pathological symptoms.
