Journal of Experimental & Theoretical Artificial Intelligence (JETAI) is advancing scientific research in artificial intelligence (AI) by providing a public forum for the presentation, evaluation and criticism of research results, the discussion of methodological issues, and the communication of positions, preliminary findings and research directions. JETAI features work in all subfields of AI research that adopts a scientific rather than engineering methodology, focusing on work in cognitive science, problem-solving, perception, learning, knowledge representation, memory and neural system modelling. All papers are peer-reviewed.
