The stimulation of the sense organs is known as:

Sensation refers to the process by which our sensory organs receive stimuli from the environment and convert them into neural signals that can be interpreted by the brain. This includes the detection of physical energy by our senses—such as light for vision, sound for hearing, and chemicals for taste and smell.

In the context of infant and toddler education, understanding sensation is crucial because it is through sensory experiences that young children begin to explore their world. Sensory stimulation plays a vital role in their cognitive, social, and emotional development, offering them a foundation for learning. In contrast, perception involves processing and interpreting those sensations, while emotion relates to feelings experienced as a response to stimuli. Discrimination refers to the ability to differentiate between various stimuli.
