I sometimes feel several in combination on some subjects

Via Forbes...

For those of you Philadelphia sports fans who think that there are only two emotions (disgust and disappointment), a study just published in the Proceedings of National Academy of Sciences says otherwise. In fact, Alan S. Cowen and Dacher Keltner, PhD from the University of California, Berkeley, identified 27 distinct categories of emotions. And here they are, by alphabetical order and not desirability or importance:

Admiration

Adoration

Aesthetic Appreciation

Amusement

Anxiety

Awe

Awkwardness

Boredom

Calmness

Confusion

Craving

Disgust

Empathetic pain

Entrancement

Envy

Excitement

Fear

Horror

Interest

Joy

Nostalgia

Romance

Sadness

Satisfaction

Sexual desire

Sympathy

Triumph

If this entire list sounds like a recent evening with your significant other, you may want to re-assess the stability of your relationship. Of note, hungry and constipated are not two of the 27 emotions listed.

For the study, Cowen and Keltner collected 2,185 short videos that aimed to elicit particular emotions such as five to ten second clips of a pig falling out of a moving truck, a cat giving a dog a massage, an attacking lion, a man with a spider in his mouth, Bernie Sanders (without a spider in his mouth), a mushroom cloud, sexual acts, and an awkward handshake. They then showed samples of these videos to different study participants on the Amazon Mechanical Turk and then asked them to report their resulting emotional experiences via either free form responses (for a total of 27,660 responses), rating how the video made them feel among 34 emotion categories of interest (for a total of 19,710 ratings), or on scales of 1 to 9 across different dimensions such as positive versus negative or excitement versus calmness (for a total of 276,696 responses). Using all of these responses, they then tried to determine what types of emotional categories were truly distinct and necessary to represent different responses and which were actually synonyms or duplicates.

In the end, they came up with the 27-item list above. Note that this doesn't mean a given event will only evoke a single emotion. For example, hearing the song "All About that Bass" may result in a combination of different percentages of nostalgia, disgust, and horror. Think of the categories as different ingredients that you use in the emotional Soufflé that is your reaction to an event or situation.
