Better psychmotor skill devemopment through, repetition on a simulation device.
Less opportunity for subject fatigue/injury. Reduction in the amount of time and frequency that student subjects must endure practice procedures and potential diseqalibrium from constant heat movents, etc.
Injured students can provide a manikin as an alternative to themselves.
Strength and finesse training: Stronger students develop finesse whilst students with less strength can use the manikin as a resistance training device develop prehensile, digital, and upper body fitness and power.
Increased chance of learning correct engrams for procedures. One partner stabilizes thhe manikin and monitors the practing partner for correct procedure components.
Remedial students can practice on the manikin repetitively with less dependence for extra practice on "friends".
Consistent evaluation platform: Before giving permission to practice on his or her own neck, a student subject can observe practice on a manikin.
