I always hate people that give advice that covers every kid. Certainly the advice, generally given, is that no kid under the age of 10-12 should watch Survivor because of the dysfunctional behavior and social interactions that are portrayed on-screen. I mean, really, I'm a trained Psychologist, so what am I doing exposing my preschooler to this kind of role model, right?
Well, it really depends on the nature/temperment of the kid and whether or not you can be there during the show to explain why these social shenanigans are occurring, and how the game is set up to make people behave in that way. While my daughter still can't sit through the perilous scenes of an animated Disney movie at 5 (think: Ursula in Little Mermaid or the Shark scene in Nemo), she can so totally grasp the intentions of the "contestants" on Survivor and understands how to see things from each player's view. In that way, she can provide a narrative of the driving force behind what each person says, and dare I say has some empathy for their plight -- even if they end up lying. We have ample opportunity to discuss bad words, bad motives, and bad friendships. We try to predict who was the most persuasive prior to Tribal Councils and who will do better at the challenge games (because of strength, smarts, eating, or motivation). We discuss how people must feel when they aren't able to eat good food, how leaders rise to their positions -- and can be dropped from those positions if they become too bossy, and how even liars wrestle with their decisions to lie (with a few exceptions, that is).
If you think that similar sorts of "social games" don't occur in school, think again. I'd like to think that exposing my kids, with lots of explicit instruction about what they're seeing, to small doses of this behavior allows them to not be caught off-guard or devastated when the group dynamic at preschool/elementary school shifts out of their favor. It happens.
