 It is in this respect that the MDM shares some elements with higher-order theories. The contents that compose the serial narrative are at least implicitly those of an ongoing if virtual self, and it is they that are most likely to be expressed in the reports the person makes of her conscious state in response to various probes. They thus involve a certain degree of reflexivity or self-awareness of the sort that is central to higher-order theories, but the higher-order aspect is more an implicit feature of the stream of contents rather than present in distinct explicit higher-order states of the sort found in standard HO theories.
