The speed of your smile can have an impact on the first impressions created in others, according to a new research. Smiling too quickly can lead others to think that you are insincere, while slow grins appear more genuine.
As part of the research, a team of business advisors examined how smiling can give clients a positive impression.
They discovered that a smile, which appears too swiftly and does not extend to the eyes can sends signals that you lack sincerity.
The Enthusiast - A huge smile showing all of your teeth and wide eyes can be overbearing.
The Big Freeze - A constant, practiced smile that lacks sincerity.
The Robot - A tiny, polite smile that doesn't display warmth.
"Studies show people perceive a slower, natural smile which floods the entire face to be more genuine," the Sun quoted Lesley Meechan of the Glasgow-based Go Group as saying.
Psychologist Bridget Hanna added: "Smiling all the time appears over-pleasing and lowers your status."
