One of the main problems attributed to the higher-order theories of consciousness (HOT) lies in its consideration of non-human animals, as well as infants, as non-conscious beings. In response, some HOT theorists, such as Rocco Gennaro, argue that this claim is based on a false assumption, while others, such as Peter Carruthers, deny that the nonattribution of consciousness to animals is a problem. The present work will describe the criticism mentioned to the HOTs, as well as the two possible replies presented by Gennaro and Carruthers. Taking sides for Gennaro's proposal will be carried out a critical review of the second. [ABSTRACT FROM AUTHOR]
