Sensory overload occurs when one or more of the body's senses experiences over-stimulation from the environment. There are many environmental elements that affect an individual. Examples of these elements are urbanization , crowding , noise , mass media , and technology .
Poor writing skills must interfere significantly with academic progress or daily activities that involves written expression [1] (spelling, grammar, handwriting, punctuation, word usage, etc.).
