The notions cognitive space and cognitive/mental maps were proposed in the late 1940s, and have been extensively studied since the 1970s within behavioral geography, as well as within tangent disciplines, notably environmental psychology and architecture. Viewing these notions from the perspective of the 2000s, one can state that the hidden assumption, or ontology, for space, on which these notions were based, was that space constitutes a personally experienced, real, material entity. The massive introduction and adoption of information technology for personal uses as of the 1980s brought about a wide exposure of individuals to a virtual and immaterial space: cyberspace. Virtual space has been constantly experienced by users of the Internet, as well as by individuals communicating through fixed and mobile telephones. The objective of this article is to examine cognitive cyberspace, suggesting its classification into two classes--cognitive information cyberspace (CIC) and cognitive communications cyberspace (CCC)--based on an equivalent classification of cyberspace into information [cyber]space (IC) and communications [cyber]space (CC). Of these two latter classes of cyberspace, communications cyberspace (CC), which is proposed in this article, will receive special attention, through its comparison to information cyberspace (IC).
