Forest have got off to two wins and a draw under the former England Under-21 boss and they currently sit fourth in the Championship.
They booked their place in the second round of the League Cup last week with victory over Tranmere Rovers, and Cohen has been delighted with his new boss' approach.
The 27-year-old believes that Pearce's no-nonsense style has earned him plenty of admiration amongst several members of the Forest squad.
The likes of Ishmael Miller, Matt Derbyshire, Gonzalo Jara and Radoslaw Majewski are just some of the players who have left the City Ground this transfer window, but Pearce's way of handling matters has caused none of the departures to bare a grude, according to Cohen.
The Mirror quotes him as saying: “The manager has been great. He’s come in with his own ideas.
“He’s the straightest person I’ve ever worked with. You can see by the changes he’s made. No one has left with any animosity towards him. He’s told them straight if they are going to play and be in his plans and made the decision from there.
“You get a lot of clubs and managers that would string people along. Players just want to know where they stand. And if any one proves him wrong he will be the first to admit that and put them back in the team.
“He’s been true to his word at that as well.”
Cohen also thinks that the additions made to the squad this summer have given them every chance of finally escaping the second tier and leaping up to the Premier League.
Forest were relegated way back in 1999, and the winger thinks that a return to England's top table is long overdue.
"I can’t remember us having this dynamic or attacking players that we have at the moment – Britt Assombalonga, Matty Fryatt, Chris Burke and Michail Antonio have all come in," he added.
"We don’t want to be in the Championship forever – we’ve been there a lot longer than what we thought. It’s time for us to get ourselves out of it.
“Bookmakers always make us favourites but talk is cheap. Every year we have ambitions but we believe this could be our year.”
Pearce's side travel to Bournemouth on Tuesday evening.
