Mings joined Villa late in the January transfer window in search of regular first team football.
As he hopes to end his loan spell by helping the team win the Championship play-off final, Mings has spoken about the impact the move had on his career.
"It played a big part in me choosing to come here, knowing there were people like that on the coaching staff," said Mings to reporters.
"John Terry is a fantastic centre-back – a centre-back that a lot of people would put in their all-time Premier League XI. When I knew there was a chance that I could come here and learn from someone like that, it was an opportunity I couldn't turn down.
"We sit down after my games and go through clips and work on the training pith together and he's been a big help in helping me to improve my positioning and decision-making at centre-back.
"When we sit down after games, that period then is probably where I learn the most. Any little tips or hints or advice about what he would've done or what his past managers have told him is invaluable.
"We've sat down many times and his overriding advice to me is go through the game without being seen. He tells me that a lot. Those little bits of information are great."
