In line with previous scholarship criticizing Hall's model, Ross and Morley argue that the model has some unsolved problems. First, Morley mentions that in the decoding stage there is a need to distinguish comprehension of the text and its evaluation. Comprehension here refers to the reader's understanding of the text in the basic sense and the sender's intention, and to possible readers interpretations of the text (borrowed from Schroder). Evaluation is how readers relate the text to the ideological position (also borrowed from Schroder).
