“…Struck by cupid's arrow, the prince is overcome by the beauty of a princess; the romantic comedy heroine helplessly succumbs to her irrepressible attraction for the insufferable, but strangely appealing male lead; and on the flip side, the reality dating show star laments that “there just wasn’t that spark.” Research over the past several decades has begun to converge on a definition of romantic passion, however, a consensus has yet to emerge on what ultimately fuels and snuffs out such illusive passionate feelings. To help illuminate how passion develops, dissipates, and how it might be revived, we review four different theories and models of romantic passion from relationship science to better understand the source of this sought‐after, but hard‐to‐attain state (Carswell & Finkel, 2018; Carswell et al., 2019; Hatfield & Rapson, 2006; Simpson et al., 1986). Given that these models and theories have largely been proposed and investigated independently, we aim to highlight how these different perspectives diverge in their predictions and might be better integrated into a more comprehensive model of romantic passion.…”
