"I think I lost the second set because I started getting annoyed with myself. So I sat down after the second set and I thought: 'Well, if I want to win this, then I've got to change my attitude'," she explained.
Robson was born in Melbourne but, asked by an Australian journalist if she felt much of a connection to the country, a chorus of boos arose from the assembled British press and a laughing Robson said: "No."
The Wimbledon resident has been thrown into the media spotlight in recent days but said she had no idea what commercial requests were now coming her way.
"I don't deal with money," she said. "I don't (even) get any pocket money, unfortunately."
And she is also dealing well with seeing herself splashed across all of the newspapers.
"I saw the front cover of The Times today, and I have to say that was a pretty shocking picture. You try to ignore it and then just focus on your match really.
"It's weird seeing yourself on the front page of every newspaper, and seeing yourself on TV as well as making quite stupid comments."

Her Wimbledon run is also bringing Robson a host of new fans.
"This morning there were quite a few people watching my practice. So there was about 100 there. I was thinking I usually don't get this many people watching my matches, let alone practice. But going onto Court One today, I was shaking because I saw the match before me and I saw how many people were on there. Then I had really, really good support."
Robson, who does not turn 15 until January, also tried to play down suggestions that she was the new bright future of British tennis.
Asked if the British game had been in a dark tunnel, she replied: "I wouldn't say that because Anne Keothavong and Elena Baltacha both got to the second round this year and they've all improved their rankings a lot. I try not to really think about it that much, and then I'll try keep getting good results really."
Despite her success at Wimbledon, Robson will not be competing in the juniors at the US Open - this year's final Grand Slam.
"I am not playing there because of the tournament restriction for the age," she said. "Then if I wanted to play Australian Open and its lead-up tournaments, then I wouldn't be able to play US."
