Final answer:
The statement suggesting the use of blindspots as guidelines for effectively turning is false. Safety protocols require checking and clearing blindspots appropriately, using visual checks and proprioceptive feedback instead of relying on them as guidelines.
Step-by-step explanation:
The statement 'In order to effectively turn forward and back, blindspots should be used as guidelines' is false. When driving or maneuvering, one should always aim to minimize the reliance on blindspots as guidelines because they represent areas where visibility is poor or nonexistent. Instead, you should use proper techniques to check blindspots, such as looking over your shoulder to ensure they are clear before turning or changing lanes. An understanding of perspective and field of view is crucial to safely navigate without solely relying on blindspots.
Exercises that involve holding up your fingers and focusing on one, while alternately closing each eye, demonstrate how our brain uses parallax to determine the distance of objects. This effect is more pronounced when an object is closer. However, this visual feedback is just a part of the sensory information used in understanding our environment and guiding movements like reaching out or driving.
Another aspect of sensory information is proprioceptive feedback, which gives us a sense of the position and movement of our bodies without visual input. This is tested in field sobriety tests (FST), where drivers may be asked to touch their fingertip to their nose with their eyes closed, relying entirely on proprioception.
