The Scots have improved dramatically under Gordon Strachan this year, particularly in the past few months, and Hanley has been impressed by the momentum within the camp since the World Cup qualifying wins over Macedonia and Croatia.
"We need to head to Norway and hope we can keep our wee run going," Hanley said. "It's all about momentum as we prepare for the next European Championship campaign.
"I think there is a difference in the mood in the camp from a few months ago. Before when we went into these games like Croatia away, we had nothing to lose.
"We were always positive but that's not the same as believing you will win. But now that we are on the back of a wee run and our performances have picked up, we can take a bit of confidence into the games."
Scotland, who drew 0-0 with the USA at Hampden on Friday night, next meet Norway in Molde on Tuesday.
