The Magpies hover just above the League Two relegation zone following their 2-0 loss at Accrington Stanley.
Notts currently have the worst goal difference in the league and have suffered 17 defeats out of 29 games, but Nolan insists - speaking from experience - that a more constructive approach works better.
"I know I am a shouter and bawler on the side, but in the dressing room I don't because I want the message to get across," he told the Nottingham Post.
"I remember when I was a player you sort of switch off when somebody is having a go and becoming confrontational.
"If you talk to the players how you would if you had won then I think it sinks in more.
"The majority of the time I just say how disappointed I am, what I was disappointed with and why. They will get all the information back once I have shown them the video.
"But it's important that we don't get too high when we win, and too low when we lose.
"We have to keep a happy medium. That is what I am here to do as are Tommo (Richard Thomas) and Norm (Mark Crossley).
"But the players know what is expected of them and come the end of the season I am sure we will be happy."
