“Eighth Grade” star Elsie Fisher: Social media has “made me more anxious”

In Bo Burnham’s new dramedy, “Eighth Grade,” Elsie Fisher stars as Kayla, a painfully shy 13-year old stumbling through her last week of middle school, while spending a good chunk of her day online, absorbed in social media. Fisher talked to Tracy Smith about how she believes easy access to the internet is accustoming young brains to be over-stimulated. Director Bob Burnham concurs.
