It’s holiday party time. Here’s how to nail a first impression (and correct a bad one).

There are some proven ways to make an instant connection with anyone—and create a favorable impression. "Making eye contact generally conveys more confidence and perceived intellect when interacting with another person or group," says Christine Weber Ph.D., a clinical neuropsychologist in Seaford, New York. At many events, you won't have much time to interact with one person. But that doesn't mean you shouldn’t make the effort to give them your full attention. "A first meeting should feel warm, welcoming, and unrushed," recommends Dudley.

An overly talkative person can turn people away—that's why it's important to speak thoughtfully and listen attentively. "Say your name, and then add, 'It’s wonderful to meet you,' or a similar phrase, but allow the other person to not only reciprocate with the initial greeting but also to initiate the conversation that comes afterward," says Dudley. Every meeting is different, and if you have the opportunity to be a little prepared, seize it. "If you have specific information about the context of the first impression ... it is helpful to make any adjustments that might strengthen the first impression," says Krimer.

If you feel things aren't going right during your interaction, come clean about it. "You don't want to be fake—that's clearly misrepresenting yourself," says Hannah Roberts, Psy. D., a licensed clinical psychologist based in San Luis Obispo, Calif. While first impressions are important, don't try too hard to impress. "Most people’s 'spidey senses' are very well-tuned to detect insincerity, so it’s important to cultivate a genuinely warm smile, an assertive handshake, and a true, heartfelt interest in others," says Dudley. "In other words, it has a lot to do with where you’re coming from: if you’re truly happy to meet someone, they’ll sense it from your body language, your tone of voice, your facial expression, and your words." And if you feel your first meeting with someone didn't go that well, there's no harm in picking up the phone and saying: "Hey, I was having an off day, I'd love to meet again!"
