ABSTRACT
The field of ergonomics can be divided into two broad categories: physical ergonomics and cognitive ergonomics (Kroemer et al., 1994; Van Der Verr, Bagnara, and Kempen, 1992). Given this division, the list of cognitive factors goes well beyond purely cognitive functions to encompass all mental activity. Thus, this list includes:
1. Psychomotor skills 2. Sensory and perceptual skills 3. Affective responses and motivation 4. Attention 5. Learning and memory 6. Language and communication 7. Problem solving and decision making 8. Group dynamics and teamwork
In terms of our understanding of these basic mental functions, cognitive ergonomics draws heavily upon the fields of psychology and linguistics (Anderson, 1993; Fleishman and Quaintance, 1989; Proctor and Dutta, 1995; Proctor and VanZandt, 1994; Rasmussen, 1988; Sheridan and Ferrell, 1974).
