This paper looks at the three main information processing models from the point of view of researchers in confidential human factors databases. It explores conceptual problems with two of these information processing models, and goes on to explore possible advantages of adopting a 'connectionist' paradigm. Links between connectionism and situated cognition are demonstrated. Practical work carried out using a connectionist/situated cognition model is described, and the way in which the situatedness of discourse can influence the kind of data that can be collected is discussed. Finally it is argued that more emphasis should be placed in ergonomics on sociation, situatedness and embodiment, and that this might help to deal with problems faced in creation and interrogating databases: especially as regards the creation of coherent and reliable 'coding taxonomies'.
