Unlike our other senses, touch acts on our feelings as a personal sensation generated within ourselves. For example, when seeing beautiful autumn leaves, we do not think of the effect of feeling that they are pretty as being something that occurs within ourselves. However, when we stroke a pet, we feel calmer and find even just looking at it soothing. This is because touch and vision stimulate each other, causing feelings in our brain. Stimulating emotions in this way is one element of the sense of touch.
