This study had like 45 participants... how does one control for other variables with such a small population? Keep in mind ScreenQ is just a fancy name for a survey geared towards screen usage. It’s hard to think that income has something to do with this.<p>I grew up in a household where my sister and I were beneficiaries of a high earning father. My mother stayed home with us and never let us watch TV. Then my brother came along and when he was 3 and I was 7, my father lost his business. Almost overnight, our lives changed, and I recall walking home from school (this was surprisingly common in Queens in 1995) and immediately plopping down in front of the TV with my brother while both my parents worked.<p>It wasn’t until I had a child of my own when my mother told us how she painfully remembers having to make this choice: “we had no money, and we couldn’t afford a caretaker. On the one hand, we could have lived in worse conditions, and I would have bored you to death. On the other hand, there was 0% chance of vacations and showing you all various cultures- but with cable TV, you all had a better chance of acquiring culture.”<p>Conclusion: I didn’t get much screen time until about 7. My brother got a lot of it from 3. Let’s just say the data (n=3) shows that there is a positive correlation in cognitive development for the 1 of us who watched excessive TV around pre-school age vs. the others. I will never let my kids watch as much TV as my brother did when I was 3, but this is purely a function of money- I’m very fortunate to make good money and able to throw $60k a year on daycare + activities + nanny to provide entertainment away from the TV. By extension, Money is the causal factor.
