 The format of a representation is different from its content. Two representations can have the same content but different formats. The usual starting point of talking about representational format is the difference between the way pictures and sentences represent. Pictures represent imagistically or iconically and sentences represent non-imagistically or propositionally. They may represent the same thing: say, a red apple on a green table. But they represent this red apple on a green table differently (for example, to just mention one often-emphasized difference, very few parts of the sentence “there is a red apple on a green table” represent part of what the sentence itself represents, whereas many parts of the picture of the red apple on a green table represent part of what the whole picture represents) – the format of the representation is different.
