“Numerous studies have shown that when presented with photographs……people can reliably identify at least six ‘primary’ emotions: happiness, sadness, anger, fear, surprise, and disgust. In one study, participants from 10 different countries – Estonia, Germany, Greece, Hong Kong, Italy, Japan, Scotland, Sumatra, Turkey, and the Unite States – exhibited high levels of agreement in their recognition of these emotions (Ekman et all. 1987). (Information found in Social Psychology 8th edition, by Kassin, Fein, and Markus, published 2011).
In humans, brain cells, called neurons, communicate with each other by using chemicals called neurotransmitters. One kind of neurotransmitter, beta-endorphin, has been found to increase above normal levels after consuming a “sweet, chocolate beverage.” (Melchior, Gigaud, Colas-Linhart, Petiet, Girard, and Apfelbaum, 1991). Beta-endorphins have the ability to induce a mild euphoric state similar to how one feels when seeing a loved one.
Only a tiny part of your eye, called the fovea, sends messages to the brain that produce detailed vision. Your eyes are constantly moving so that you can see everything in the world clearly. When you look at an object, you are moving your eyes to make the image of that object fall on the fovea. If you don’t, you can’t really see the object well.
When humans are presented with a stimulus, such as a sound, we will turn our attention toward that stimulus, even before we know what it is. And, in the case of sound, humans will actually turn their head in the direction that is closest to that stimulus. This process is known as the orienting response, and it has also been demonstrated by mammals and other animals in nature.
