Vernon looked like a player shorn of confidence when he passed up several good chances in his first appearance of the season, a 2-1 defeat by Hearts in August.
But he came off the bench to fire an impressive winner against Inverness last month and followed that up with a hat-trick against Falkirk in the League Cup.
The Englishman scored 28 times in his first two seasons at Pittodrie but the goals dried up last term and he only struck twice in 10 months before his recent spree.
And he admits his confidence had suffered before he re-ignited his Dons career.
"A striker scoring goals is a lot happier and feels like a lot better player than a striker that's not scoring," said Vernon ahead of the Scottish Premiership visit of Dundee United.
"It's good for my confidence. Early on in the season I wasn't playing as much as I would have liked. I managed to get a chance and do the business and get a few goals.
"I'm not looking to rest on my laurels and kick on and get more goals now."
The 29-year-old could not deny that confidence is a huge factor in the life of a centre-forward.
"I'd like to say it's not but it is," the former Oldham, Blackpool and Colchester player said.
"With all strikers, it's a confidence position. Most positions on the pitch are confidence positions but strikers are under pressure to score goals.
"If you go a few games without scoring all of a sudden the pressure is on.
"It's that fine line of getting a goal or two and then all of a sudden you are in a totally different mindset and feel like a different player. That's how much it can change really."
Aberdeen sit a point above Dundee United in fourth place and Vernon admits the New Firm clash is a big test of their early-season progress following four consecutive years outside the top six.
"Dundee United have been up there the last few seasons making the top six," he said. "They have proven time and time again they can do it.
"It's a big aim of ourselves to be up there this season. We feel we have had a decent enough start to the season.
"If we can kick on from there now and turn those niggly performances where we are not playing so well and losing into maybe getting a draw and nicking a win, we feel we can definitely do that."
