The Brit reduced Rosberg's lead at the top of the standings to four points with a victory in the British Grand Prix, but Hamilton is eager to dismiss suggestions that each driver has been trying to get the edge over their rival off the track.
"I'm not trying to play mind games with Nico, he's a very, very intelligent driver," the 29-year-old told reporters. "You talk about mind games, we're not playing mind games but every time you go faster that has an effect on the mind.
"Inevitably you say something and people can interpret that as mind games, but this year we are fierce competitors and going to be head to head for hopefully the rest of the year so hopefully whoever can keep their head more, and most, will probably come out on top."
Hamilton and Rosberg will renew their rivalry at this weekend's German Grand Prix.
