"Matcha" Marshmallow Test

I’ve read an article about “marshmallow test” done in the US. Sounds interesting and appetizing, but no idea what it’s about. Do you know that? Have you done that? Anyway, this is about the test.

The Stanford marshmallow experiment was a series of studies on delayed gratification in the late 1960s and early 1970s led by psychologist Walter Mischel, then a professor at Stanford University. In these studies, a child was offered a choice between one small reward provided immediately or two small rewards if they waited for a short period, approximately 15 minutes, during which the tester left the room and then returned. In follow-up studies, the researchers found that children who were able to wait longer for the preferred rewards tended to have better life outcomes, as measured by SAT scores, educational attainment, body mass index (BMI), and other life measures.

A days after I read the article, I happened to find “matcha milk marshmallow”, and I bought it. If I had done this test, I wouldn't have waited....:-)
