The distinction between adjectival and adverbial qualia in consciousness is discussed in relation to our sense of being present in a task or game like Tetris, which doesn't have realistic graphics but can induce a sense of immersion, compared to a video game with high verisimilitude which may lack the same sensation. Semantic memory is also touched upon, which stores knowledge such as "cats are mammals" and can be measured through coherence, correspondence and conviction tests.
