More specifically, a laboratory experiment conducted by an Australian team suggests that this “power” would require between 108 and 116 thousandths of a second.
We can see it as a legacy from a distant time when our ancestors, hunters and gatherers, did not have a supermarket but had to find food among bushes and tree leaves. And this is essentially just with the eyes, since the sense of smell is not the best human sense.
However, this speed of execution would still be useful today, note the three psychologists from the University of Sydney, whose article was previously published on the BioRxiv server. In fact, brain activity wouldn’t be the same depending on whether the “guinea pigs” discovered processed or “natural” foods in the photos they were shown.
In other words, there would be something in our brain that would make a difference in a split second. A skill that would still make sense today, in the aisles of a supermarket where we are bombarded with information. And a skill that could help us decide on the fly what’s best for our health – as long as advertising or tempting packaging doesn’t distract our attention and play on our emotions. .
