How are symbolic and analogical representations similar? both are mental images. both require thinking. both involve symbolism. both are a basic element of thought. all but choice c sir/madam, the best answer is "a. both are mental images."?

The correct answer is: "all but choice C"

Analogical representations: are mental or artificial images which closely replicate the physical characteristics of the original reality (object, place...) that it aims to modelize. For example, maps, pictures or diagrams. Symbolic representation: it is an abstract type of representation in the sense that it aims to replicate a reality without using its physical characteristics. The main example would be writing. Another example could be using a logo, or a color code, etc.

Therefore both are mental representations, both require thinking as they consist on elaborating on the information that the human mind perceives through its senses, and both are basic elements of thought, as they help to create linkages among differente knowledges: experiences, concepts, etc.
