Can you tell if these two faces are the same or different? How about these? Or these? If you’re like most adults, it will be easier for you to identify different adult faces compared to the infant faces in the second example, and even the small children’s faces in the third example. This makes some…

Baby signing in the real world

Take a look at this video made by fellow ScienceBlogger Dr. Isis. She’s talking with her son, a toddler who adorably mimics her as she says very complicated words such as “Adventures in Ethics and Science” and “Wackaloon” (but sadly, not “Cognitive Daily”): It’s cute, but it’s difficult to say whether Dr. Isis is really…

Baby sign language is all the rage these days. Upscale day-care centers and nanny services promote it as a better way of understanding what babies want. Babies have been known to reliably produce signs as young as 5.5 months, and studies have shown that they reliably produce signs significantly earlier than spoken words. As we’ve…

One of things I was taught over and over again when I was in education school was the importance of getting parents involved in kids’ learning. If you get the parents on your side, my professors insisted, then you’re going to be much more able to get through to the students. I didn’t last long…

When Jim and Nora were toddlers, they were huge fans of everything Disney. Here they’re wearing their Disney pajamas as they play next to their Seven Dwarves figurines, underneath their TV, which was frequently used to watch Disney videos. We even took them to Disney World, where they had an absolute blast, but turned out…

Nora was an excellent talker, starting at a very young age, but that didn’t mean that she couldn’t express herself in other ways. Here, for example, she points to a the item she wants. It’s entirely possible that she didn’t yet know the word “stick,” but she was still quite able to express her desire.…

When Jim was 12 or 13, he seemed to want to watch almost every R-rated movie that came out. PG-13 movies were okay, and PG and G-rated movies were beneath his dignity. Was he simply interested in these movies because they were forbidden (as we contended), or was he somehow more drawn to the content…

When Jimmy and Nora were toddlers, we bought them great little plastic scooters to ride around the house. They were the perfect size for a small child. Yet Jimmy preferred to ride around on a plastic garbage truck instead, despite the fact that there was no steering wheel and the “seat” wasn’t nearly as comfortable,…

One of Jimmy’s favorite toys as a toddler was a simple little bucket of blocks. There were three shapes: a rectangular prism, a triangular prism, and a cylinder. The bucket’s lid had three holes: a square, a triangle, and a circle (The picture at right was the only one I could find online — this…

“Impossible objects” like the etchings of M.C. Escher have fascinated adults for centuries. You can’t help but stare and wonder at a drawing like this, which seems to defy the laws of nature: The drawing seems strange to us because our visual system tells us that when an object or part of an object occludes…
