This research takes a post-postmodern stance to investigate tourists' predisposition toward alterreal authenticity (i.e., altered reality). It draws on Schachter's two-factor theory of emotion to highlight a model that examines the effects of authenticity and cultural difference, and their interactions on cultural-heritage consumption, through a field experiment. Results point to a two-step mechanism in authenticity negotiation in which psychological arousal is diffused through exposure to authenticity stimuli followed by cognition of the arousal situation conditioned upon tourist cultural background. This research not only heeds the call from the literature to enrich the methodological silos in authenticity discourse through causal inferences; it also provides early empirics to the post-postmodern view of authenticity, which conjectures means for tourists to imaginatively authenticate their experiences.

本研究采用后后现代的立场来调查游客对异域真实性（即改变的现实）的倾向。它借鉴了沙赫特的情感双因素理论，通过实地实验强调了一个模型，该模型检查了真实性和文化差异的影响，以及它们对文化遗产消费的相互作用。结果表明真实性协商的两步机制，其中心理唤醒通过暴露于真实性刺激来扩散，然后认知以旅游文化背景为条件的唤醒情况。本研究不仅响应了文献的号召，通过因果推论丰富了真实性话语中的方法论孤岛；它还为后现代的真实性观点提供了早期经验，
