How we change what others think, feel, believe and do
In extension of the commonly-used two pleasures, Duncker (1941) identified identified three types of pleasure: sensory, aesthetic, and accomplishment.
Sensory pleasure is that which is gained from stimulation of the five senses, and is the same as that described in the two pleasures.
Aesthetic pleasure is that which is gained from observing or experiencing beauty. This includes natural beauty, such as when you stand on a mountain top and marvel at the view, as well as created beauty, such as the wonder of walking around a well-carved statue.
Industrial designers often seek to combine aesthetics and functionality, so you enjoy the products that you use.
Accomplishment pleasure comes from doing something and achieving one's goals.
Much of life is about seeking to achieve and accomplish. We develop skills and then apply them repeatedly to gain that sense of accomplishment we desire.
Some people can get the sense of accomplishment by themselves. Others need affirmation, with praise and recognition by another person to confirm that they have accomplished something worthwhile.
Give people things to accomplish. Acknowledge what they have done. Let them create. Show them beauty. Use those things that are pleasurable to motivate them.
