Take dopamine. Elevated levels of dopamine in the brain produce extremely focussed attention,2 as well as unwavering motivation and goal-directed behaviors.3 These are central characteristics of romantic love. Lovers intensely focus on the beloved, often to the exclusion of all around them. Indeed, they concentrate so relentlessly on the positive qualities of the adored one that they easily overlook his or her negative traits;4 they even dote on specific events and objects shared with this sweetheart.
In her book "Why We Love," Helen Fisher explores the role of dopamine in romantic love. Elevated dopamine levels in the brain enhance focus and motivation, which are key aspects of being in love. When people are in love, they exhibit an intense concentration on their partner, often ignoring their flaws and emphasizing their positive traits. This deep focus can lead to a singular devotion where every shared moment becomes significant.
This phenomenon suggests that the biochemical processes in our brains not only influence our capacity for love but also guide our attention and emotional responses. Lovers become captivated, prioritizing their relationship above all else, showcasing the power of chemistry in romantic connections and how it shapes our perceptions of those we adore.
