Psychomotor behavior is the activity of receiving sensory input signals and interpreting and physically responding to them. HUMANS can receive inputs by vision, HEARING, smell, and the cutaneous senses, which respond to temperature, mechanical energy, or electrical energy. Kinesthesis and the vestibular sense inform about location and position. Vision FOLLOWED by hearing are the most important senses for TRANSMITTING signals carrying complex information for decisions and for control of MMSs. Signals for warning or alerting need not be complex and can be transmitted by one or a combination of the sensory channels. The choice is determined by the situation and the task being performed by the person or persons to be warned rather than by differences in modality reaction times.
