Tunnel vision observation like the name goes is a type of observation in which a person can only see through a straight line and does not observe any other thing that is not in the line of his sight.
A tunnel is narrow and dark. It is a way through which trains pass through at high speed. So anybody with a tunnel vision observation only sees or observes things that are within the line of his vision, without seeing or observing other things in that same space.
Stimulus prompts is a cue used in conjunction with the instructional
materials and in these case, the positioning of the target item closest to the client while the distracter items are placed
slightly further away from the learner best describe position cues.
