Lewis Hamilton has insisted he will continue to rely on his family for any mental support rather than turn to a sports psychologist.
At the last grand prix in China, Mercedes enlisted the services of renowned sports psychiatrist Dr Ceri Evans who played a key role in helping the New Zealand All Blacks win the 2011 Rugby World Cup.
Evans observed the team over the course of the weekend at times when they were involved in pressure circumstances during qualifying and the race before passing on his findings to Mercedes motorsport boss Toto Wolff.
Evans’ visit was a one-off, and whilst neither Hamilton nor team-mate Nico Rosberg had any contact with the 50-year-old, he may return at some point in the future should the team require the need.
Hamilton, who has won the last three grands prix to close the gap to Rosberg to four points in the drivers’ standings, has confidence in his own ability that he does not need outside help.
“It has zero impact on me. Zero. I don’t speak to anyone like that,” said Hamilton.
“It was really for the team. They want to be the best everywhere and sometimes it’s good to get an outsider’s point of view on the way you carry yourself, communication and all those different things.
“I’m sure they’re trying to do everything as well as they can.
“There are things you can learn from different sports and they are trying to see if there is anything they can learn.
“But for me, as a driver, it’s not something I feel I need because since I was eight years old I’ve won every championship I’ve competed in, and all I’ve needed is me and my family.”
And Jenson Button fears Mercedes will face little opposition to their current dominance before Formula One’s summer break.
“Mercedes don’t have any competition. They are so far in front of the field,” said Button.
“In Monaco (in a fortnight) you might see Red Bull be strong and give them a run for their money, but apart from that it’s going to be very tricky.”
