Earnshaw believes that winger Brennan Johnson has gone on an impressive goalscoring run due to abstaining from social media.
Johnson deleted his social media account and has since scored in six straight games.
“I think it’s different for everybody, but for sure there’s something in it because I think for him it was clearly affecting him with social media and it’s (deleting the account) clearly had a real positive impact," Earnshaw told BBC Radio Wales.
"It’s no coincidence for him because I think the reason he deactivated it was because of all the negativity and everything was going into his game and over thinking and then all of a sudden he was thinking about that as he’s playing."
Johnson scored for Spurs in a 3-2 loss to Brighton on Sunday in the Premier League.
