When you’re scrolling through profiles on a dating app, the first thing you probably look at is the person’s picture. If they seem attractive to you at first glance, you may explore their profile further and then decide whether you want to communicate with them; however, if their picture doesn’t pique your interest in that split second, you probably move on to the next one. Physical attraction is often instant, and it can contribute to feelings of excitement, increased energy levels, and craving for physical connection upon seeing someone for the first time. Instant physical attraction and the ensuing emotional response are contributing factors to what people call “love at first sight.”
