Nervous about making a bad impression at a holiday party? Don't be. Far fewer people than you think will even perceive if you make a social flub.

At least that's what a study revealed when college students were asked to don a Barry Manilow T-shirt before entering a room full of people. Here's how many people actually noticed.

Despite the college students' worst fears, only about half the people they expected to actually did notice the famed "Copacabana" singer emblazoned across their chests. Researchers dub this situation the "spotlight effect." What it means is that in social situations, people tend to grossly overestimate how much others are paying attention to their actions or appearance. (Are you always anxious?
