 Do you remember your first crush? Maybe you're finding yourself very attracted to someone at the moment. Attraction is something most of us experience throughout our lives and crushes can be incredibly powerful. Maybe you're wondering if someone has a crush on you or how to attract that special someone. If so, watch on for eight psychological facts about crushes. 1. Prolonged eye contact can increase attraction to your crush. Kellerman, Laird, et al. 1989 decided to look at the effect eye contact can have on how much we like someone. They had strangers engage in mutual gaze, looking at each other in the eye, and then had the participants rate each other. They found that this prolonged eye contact increased attraction and attachment to the stranger. So, if you want to appear more attractive to your crush, be sure to look them in the eye. 2. Opposites do attract. We've all heard the saying opposites attract, but is there any truth to it? Cromer, Humel, Croy et al. 2016 looked into this saying. They specifically looked at genetic blueprints known as HLA complexes. They found that women were naturally more attracted to those with different HLA complexes to themselves. It would seem, therefore, that opposites do indeed attract, and who you crush on could come down to different genetic blueprints.

Do you know someone who always seemed to have a crush on someone older than themselves? Someone who always seems to have an age gap in their relationships? Some research has suggested this could be due to parental age. One study found an association between a child's parents being older and them finding older faces more attractive when they are adults. So, if you find you're always crushing on someone older, it could be because of your parents. 4. Those with symmetrical faces tend to be more attractive. So, what is it that actually makes someone attractive? Why is it that some people have loads of admirers? It seems to be that our brains are wired in a way that finds certain things more attractive. One constant across a wide range of people seems to be that faces which are symmetrical are rated as attractive. Does your crush have a symmetrical face? That could be why you find them attractive. 5. Sound and smell play a role in attraction. It seems fairly obvious to say sight plays a role in attraction. We tend to attribute our initial attraction to someone to how they look. However, it isn't the only sense that matters. It has also been found that both sound and smell also have a part to play in a crush developing. Specifically, it seems that a person's voice and their scent are important to that initial attraction. This makes sense as along with how they look, these two factors are things you perceive very quickly when meeting someone. So, although you may not realize, it could be more than just your crush's looks that you're attracted to. 6. We're attracted to those of similar heights to us. It has been found in various studies that couples' heights are often positively correlated. This means that taller individuals on average end up with taller partners. But why is this? Is it environmentally learned or is it genetic? T'Nessa et al. 2016 decided to look into this question. Using advanced statistical techniques, they managed to find that choice-mate height, meaning that height of our partner, was due, at least in part, to genetic factors. So, if your crush is a similar height to you, this is probably due to genetics. 7. The color red makes women more attractive to men. Red is often associated with attraction and desire, but is there any other reasons for this? One study looked at the effects color had on heterosexual men's judgment on the attractiveness of several women. It found that red made men think women were more attractive. They suggested this was due to social conditioning, because society associates red with passion. So did these participants. The study only looked at heterosexual attraction, and so it's unclear whether the same effect would be found in the same sex attraction. 8. Falling in love causes psychological changes. Falling in love is a powerful thing, which has a profound effect on us. It's been found it has a lot of psychological changes on the body. It releases chemicals, which have the effect of making us feel good. Our cheeks flesh pink, our palms sweat, and our heart race. Have you ever noticed these changes when you talk to your crush?
