I think one of the psychological strategies Disney uses is nostalgia. Parents want to relive their childhood and experience things they never had the opportunity to through their kids. They also want their children to have similar positive experiences they once had. We all watched Disney movies on replay and were glued to the TV whenever Mickey Mouse came on, parents today allow their kids to do the same. Disney capitalizes on this and bets on it being a recurring, generational, funnel for producing future customers.
