 Figuring out whether your crush likes you is one of the hardest things to figure out because when it comes to attraction, things are usually kept pretty subtle. You have to look pretty close if you want to see the signs that someone likes you. Here's what to keep an eye out for. 1. They respond to the sound of your voice. The sound of your voice can seriously attract other people. Many studies have found that women are attracted to deeper voices in men, whereas men like higher voices in women. Fast talkers are seen as more educated, and if you can change up your inflection, you're seen as more interesting. Your crush might be in love with the sound of your voice, so keep an eye out to see if they're responding to your voice with a smile or laugh. If this is the case, there might be a spark of attraction. 2. They play hard to get. The rumors are true. Playing hard to get is a big sign of attraction. When we're with someone who's playing hard to get, we usually work that much harder to get their attention, and that makes the seduction process much more intense. This all comes down to one thing, availability. Apparing to be less available can make people want you even more. 3. Uncrossed legs. Body language also reveals a lot about availability. For example, when someone uncrosses their legs and arms, they're basically saying I'm available. This is a basic body language in both men and women, so this rule also applies with same-sex couples. There are plenty of other signs of open body language, such as unturned palms, maintaining eye contact, and many more. 4. They talk about being single. Let's stick on the topic of availability, because it's such a huge factor in attraction. When someone subtly drops a hint that they're single, it's a great sign. So when someone subtly mentions that they're single, maybe it's the right time to make a move, because who knows, they might be sending out signals of availability as a sign of attraction. 5. Leaning in. A 2014 study identified five separate flirting styles, and leaning in was a huge sign of attraction that was mentioned. They specified that leaning in on an angle from the hip is a big sign of flirting. So if your crush is leaning into you after you make them laugh, it could be a major sign of attraction, so keep an eye out for that. 6. Revealing personal info. As a general rule, the more personal info a person reveals, the more interested they are in you. That's what a recent study found when they studied flirting techniques. This can still be done in a subtle way. For example, someone might reveal that they're dealing with a heartbreaking loss or a major setback, but in a slightly casual way. 7. Teasing. In that same study, the researchers also studied the signs of flirting that might arise during conversation, and teasing was a big part of that. They specified that teasing consisted of making fun of another person in a lighthearted way. We're guessing that a lot of our viewers have probably experienced teasing in their own flirting experiences. But remember, keep teasing lighthearted and fun. Never make fun of someone for things they're insecure about, no matter how much you're crushing on them. 8. Eye pupils and dilation are linked with arousal. We all know that eyes are the windows to the soul, but if you stare deep enough into your crush's eyes, you might just get a clue as to whether they're into you. Studies have shown that when people become aroused, their pupils actually dilate. This is actually a pretty good sign of sexual orientation as well. Your eyes will dilate when you look at the gender you are most attracted to. 9. Playing with nearby objects. When some people get nervous, they fidget. They might play with their hair, their bracelets, or their nails. But according to a recent study, those same behaviors might be linked with attraction. Researchers found that people who were flirting often found themselves playing with buttons on their shirts, zippers, strings, and many other nearby objects. 10. Mirroring. Another big sign of attraction is mirroring. If you look closely, you might find that your crush seems to be copying your movements and behaviors in a subtle way. You might be tilting their head to the side in the same way as you, or adopting a similar posture. Mirroring has been studied quite intensively in psychological research.
