The Wales international has been in impressive form this season, scoring goals that have helped push the Gunners to the top of the Premier League table.
"I think you make more right decisions when you play with confidence," Ramsey told the club's official website. "If I think something is on and I can hit a 40-yard pass over the top for someone to run onto, I will still do that, but the decision-making is better.
"You feel sharper in your mind when you are confident. Things just seem to happen quicker. You understand things more clearly and things just seem to happen more naturally, it's difficult to describe really."
Ramsey is expected to start in tomorrow's Premier League clash against Liverpool.
