Brief thoughts on what’s going on online

• Very young children learn better from photos. When they are read to from a picture book describing how to make a rattle, 18-months-old do better at trying to make the rattle when the book had realistic photos compared to line drawings. I’ve always found instructions that use photos very difficult to follow because it’s hard to highlight the relevant portion of the photo. But apparently at a very young age, children don’t understand the relationship between a drawing and a real object.
• Left-handers have faster connections between brain hemispheres. I knew it! Left-handers are superior! But why don’t we rule the world? Maybe because we’re forced to use right-handed scissors and it’s harder for us to open jars.
• A woman’s age when she gets her period affects her kids. Her children will be taller as kids, but more likely to be obese. Fortunately, kids who are tall when young are likely to earn more as grown-ups compared to short kids.
