Howson has challenged Norwich to put their Capital One Cup disappointment behind them by making it 10 Barclays Premier League games unbeaten when Wigan visit Carrow Road on Saturday.
"It is very important it doesn't carry on and when you get beat you always want to bounce straight back," Howson told reporters.
"It was fairly even with both teams going at it for a large period of the game and I think it could have swung both ways, so it is disappointing especially to lose here at home.
"However, the good thing is we go straight into another game come Saturday.
"Yes we are disappointed with the result, but it is a case of moving on to the Wigan game now."
