@Crispety -I think that similes, metaphors, personification and hyperboles also allow the reader to begin comprehending how the character or object feels by the use of these different types of figurative language. For example, if you use the hyperbole that the girl was starving to mean that she was very hungry it paints a very explicit picture in the mind of the reader of how this character felt.
This also helps with the development of reading comprehension because the reader can conceptualize things about the character when the language is so vivid like that. It also makes the writing more interesting in my opinion. My daughter studied examples of figurative language like this and it made her literature lessons more memorable.
