Slips (or Lapses)
In some contexts, errors are categorised as ?slips? or ?mistakes,? based on the cognitive psychology of task-oriented behaviour. Attentional behaviour is characterized by conscious thought, analysis, and planning, as occurs in active problem solving. Schematic behaviour refers to the many activities we perform reflexively or as if acting on ?autopilot.? Complementary to these two behaviour types are two categories of error: slips (or lapses) and mistakes. Slips refer to failures of schematic behaviours, or lapses in concentration (eg, overlooking a step in a routine task due to a lapse in memory). Mistakes, by contrast, reflect incorrect choices.
