One issue facing agents that accumulate large bodies of knowledge is determining whether they have knowledge that is relevant to its current goals. Performing comprehensive searches of long-term memory in every situation can be computationally expensive and disruptive to task reasoning. In this paper, we demonstrate that the recognition judgment — a heuristic for whether memory structures have ...

A fundamental question that always arises in cognitive modeling is how to combine two contradictory constraints: the model should be as flexible as possible (to reflect human flexibility) and at the same time it should be maximally efficient. The decision proposed in this paper is the following. The space to be searched has to be restricted for computational reasons, but this restriction should...

The present paper seeks to investigate the cognitive abilities of expert EFL teachers. To this aim, the existing literature was examined and ten cognitive themes were derived which were further investigated through interviews conducted with ten academics, teacher trainers and exemplary teachers of the field in the Iranian context. The ten extracted themes were attested by interviewees’ comments...

This paper develops a representation-theoretic notion of spatial context for cognitive agents that interact with spatial environments. We discuss the state of the art in defining context as used in context-aware and / or location-aware systems. In contrast to existing approaches, we define context through cognitive processes. Placing cognitive processes in the focus of our context definition al...
