Level of behavior Characteristics of level Training tools for level
Skill-based behavior -Automatic, using few attentional resources -Patterns stored in memory for well-practiced, routine tasks -Box trainers -Virtual reality simulators that address basic skills
Rule-based behavior -Requires some attentional resources -Rules and procedures are stored in memory -Individual decides which rules and procedures to apply to situations -Ex vivo or in vivo animal models -Virtual reality simulators that combine basic skills into procedures
Knowledge-based behavior -Places heavy demands on attentional resources
-No stored patterns, rules, or procedures in memory
-Used for novel, rare, or unique situations
-Virtual reality simulators that combine basic skills into procedures and also introduce complications like distractions, interruptions, or rare events
