The Manchester City boss admits tempers threatened to reach boiling point among his ranks following a lacklustre 2-0 defeat at Portsmouth on 14th February.
However, with the air cleared, the Blues have since gone on to claim notable draws on the road at FC Copenhagen in the Uefa Cup and at Anfield against Liverpool in the Premier League.
Hughes insists the battling qualities displayed during those encounters were a direct result of the post-match inquest at Fratton Park.
"Players raising their voices in the dressing room has happened for years and years," said the City boss.
Opinion"It certainly happened in my day, so there is no change in that respect. I think it is healthy.
"It is important players can voice an opinion in the dressing room. I have always encouraged that.
"I believe in self-regulation. It cannot always come from managers and coaches, it has to come from within as well.
"Our mentality in away games possibly had to change and the last two displays on the road have been excellent. We want to sustain that level of performance."
