Question

Quizplus · Accepted Answer

A horizontal line would indicate that the mechanical pen is not being moved by any response from the animal, as there is no change in the movement of the paper. A steep line would indicate a sudden change in movement, small tick marks could represent small responses, and an empty space would indicate that the pen is not making contact with the paper at all.
