and still prevalent "brain in a vat" models which ignore "situatedness, embodiment and enaction" as key to any cognitive act (Ibid.). These representation-based frameworks consider distributed cognition as "a cognitive system whose structures and processes are distributed between internal and external representations, across a group of individuals, and across space and time" (Zhang and Patel, 2006). In general terms, they consider a distributed cognition system to have two components: internal and external representations. In their description, internal representations are knowledge and structure in individuals' minds while external representations are knowledge and structure in the external environment (Zhang, 1997b; Zhang and Norman, 1994). DCog studies the ways that memories, facts, or knowledge is embedded in the objects, individuals, and tools in our environment. DCog is a useful approach for designing the technologically mediated social aspects of cognition by putting emphasis on the individual and his/her environment, and the media channels with which people interact, either in order to communicate with each other, or socially coordinate to perform complex tasks. Distributed cognition views a system of cognition as a set of representations propagated through specific media, and models the interchange of information between these representational media. These representations can be either in the mental space of the participants or external representations available in the environment. These interactions can be categorized into three distinct types of processes: Cognitive processes may be distributed across the members of a social group. Cognitive processes may be distributed in the sense that the operation of the cognitive system involves coordination between internal and external (material or environmental) structure. Processes may be distributed through time in such a way that the products of earlier events can transform the nature of related events. Early research John Milton Roberts thought that social organization could be seen as cognition through a community . He described the cognitive aspects of a society by looking at the present information and how it moves through the people in the society. Daniel L. Schwartz (1978) proposed a distribution of cognition through culture and the distribution of beliefs across the members of a society. In 1998, Mark Perry from Brunel University London explored the problems and the benefits brought by distributed cognition to "understanding the organisation of information within its contexts." He considered that distributed cognition draws from the information processing metaphor of cognitive science where a system is considered in terms of its inputs and
