Categories of Human Error

*There are many ways to categorize human error (see Jones, 1999; Wallace and Ross, 2006).
*exogenous versus endogenous (i.e., originating outside versus inside the individual) (Senders and Moray, 1991)
*situation assessment versus response planning (e.g., Roth et al., 1994) and related distinctions in
- errors in problem detection (also see signal detection theory)
- errors in problem diagnosis (also see problem solving)
- errors in action planning and execution (Sage, 1992) (for example: slips or errors of execution versus mistakes or errors of intention; see Norman, 1988; Reason, 1991)
*By level of analysis; for example, perceptual (e.g., optical illusions) versus cognitive versus communication versus organizational.
