Oddness
Any corporeal perception associated with a sense of pressure, hearing or touch is called a somatic sensation. Somatic sensations are described using words like hard, soft, loud, quiet, slap, tickle, push, pull, scream, whisper, port, starboard, bass, treble and so on. The reference experience for describing somatic sensation is hearing a heartbeat. So to make a binary description of a somatic sensation, compare it to hearing a human heartbeat. Report the result using one of the following algebraic statements. If the two experiences are not comparable, then express this by writing $\delta^{*} =0$. If the sensation is like hearing a heartbeat, then say that it is on the left. Express this as $\delta^{*} =+1$. If the sensation is not like hearing a heartbeat, then say that it is on the right and that $\delta^{*} =-1$. The number $\delta^{*}$ is called the oddness.
