Martinez replaced Moyes at Goodison Park at the end of last season.
When asked how they compare, Barkley told Match of the Day Magazine: "He’s similar to David Moyes as they both like to take over the training session and be the main man. But Martinez is more tactical. We do a lot more tactical work which is good for me because I’m young and still learning.'
"Roberto Martinez has come in and given everyone confidence. He’s a positive man and doesn’t say anything negative. I’m an Evertonian so I want the club to be up at the top end of the table and it’s great to be a part of it."
