While in a warm bubble bath, Meredith presents her son, Micah, with a musical floating duck. Meredith understands the importance of _________________________, the physical stimulation of Michah's sense organs.

The sensation is a process of taking information in our brains using the five senses (touch, smell, hearing, taste, and vision) and interpret it by the brain.

The process is

Senses detect the stimuli
The stimuli are transformed into the electrical impulses that the brain reads
The impulses move to the specific parts of the brain where they are decoded and where we understand the information.

Sensations help us enjoy our life more and make more fun of the situations, as well as understand the potentially dangerous and go through life safely.

Meredith uses musical duck as stimuli for Michah. The sensation he will have from hearing the music and seeing the duck, as well as touching it and playing with it, will help him enjoy the bath more, be less afraid of the surroundings and develop positive feelings toward the process of bathing.
