Delay of Gratification in Kids and Crows
One measure of self-control is the ability to delay gratification; namely, the ability to wait in order to obtain a more valuable outcome in the future over a less valuable immediate one. In children, the capacity to delay gratification develops between the ages of three and five years old. In a new study, researchers used a rotating tray apparatus that allowed them to test both three- to five-year-old children and New Caledonian crows.

Crows Infer Weight of Objects by Observing Them in a Breeze
Humans use a variety of cues to gauge an object’s weight without directly handling it, including how easily it can be moved. For instance, if we see one object blowing down the street in the wind while another object remains stationary, we can infer which object is heavier.
But what about other animals? I take a look at a clever new experiment with New Caledonian crows that suggests they possess this ability, too.
