According to a recent article in Distractify, at least a third of kids develop an intense interest in something–like dinosaurs or astronomy. It typically happens when children are just 3 to 6 years old, and often fades as they get older, though for some this “intense interest” as researchers call it can last throughout their lives.

“A study carried out at the universities of Indiana and Wisconsin found that children who develop an intense interest do better later in life. Joyce M. Alexander of Indiana University and her team found that this type of interest, especially those that demand a conceptual domain, “enhance perseverance, improve attention and enhance skills of complex thinking as the processing of information,” the Distractify article stated.

So now when your little one rattles off the proper name of every dino in Jurassic Park, just know as much as it drives you NUTS, it improves your kid’s linguistic skills, and is a good indicator of high understanding.
