After a slow start, the Canaries picked up their first win of the season on October 20, scraping a narrow 1-0 victory against Arsenal at Carrow Road before going 10 matches unbeaten, but keeping that run going through the Christmas period was too much to ask.
A loss to West Brom at the Hawthorns was swiftly followed by back-to-back home defeats against Chelsea and Manchester City, while their first match of 2013 saw West Ham get the better of them. However, Martin says confidence is fine at Carrow Road.
"Confidence is fine, there is no problem in the dressing room," he told reporters.
"I don't think it is an issue because of the way we have played against two of the best teams in the country, if not Europe.
"The performances were there, and it is really only in the first half against West Ham that we have not produced what we are capable of.

"There has been a tough schedule over Christmas - it does not come tougher than Manchester City and Chelsea at home, West Brom and West Ham away which are tough games.
"Fortunately we had a great run just before and now it is up to us to start getting results again.
"We need to be at the level we were in the second half to get results in this division because it is such a tough league."
Despite the four recent losses, Norwich are sitting in 12th place in the Premier League, seven points above the relegation zone, and Martin added that he is grateful for the gap that has emerged below them.
He continued: "The 10-game run has given us a little cushion over the other teams so as long as we pick up a few wins, and keep away from them, then that's fine because other teams need to capitalise and winning games in this league is tough, as QPR and Reading are finding.
"We have done a lot of the hard work, now we just need to get a few more wins to get over that line and then we will be comfortable."
