Proximity The idea of proximity is that we tend spend more time with them because they live near us, work or, go to school with us, etc. Therefore, those closer to us are seen as more attractive.
Familiarity According to this concept, it is sufficient for us to simply see a person several times for us to start to find them attractive and is called the mere exposure effect. However, it is also suggested that overexposure is possible and can often lead to disgust.
