London: If you are one of those who always wondered why many women struggle while parking their cars, it's better to understand that it happens simply due to lack of confidence, says a US study.

A research has suggested, lack of confidence is a factor in women's tendency to struggle in tasks requiring spatial awareness, a daily reported, adding that tests showed how women improved in these activities when their self-belief was given a boost.

University of Warwick psychology researcher Zachary Estes, working with Sydney Felker from the University of Georgia Health Centre, looked at the ability of 545 US students to perform a standard 3D mental rotation task, while at the same time manipulating their confidence levels.

Estes, whose research paper is published in the journal Archives of Sexual Behaviour, said: "Prior research shows that women tend to do poorly on tasks that require spatial awareness."

"...We wanted to see why that was so. We manipulated people's confidence in our experiments with spatial tasks, and it does seem that confidence is a key factor in how well women perform at this kind of task."

"Our research suggests that by making a woman feel better about herself, she'll become better at spatial tasks - which in the real world mean tasks such as parking the car or reading a map."

"So a little bit of confidence-boosting may go a long way when it comes to reversing the car into a tight parking spot," said Estes.
