Instrument decay refers to the decline in the quality of a measuring instrument over time, which can result in less detailed descriptions from the students. Regression towards the mean refers to the tendency for extreme scores to become less extreme on subsequent measurements, testing refers to the influence of previous testing on subsequent scores, and history refers to external events that could affect the emotions of the students over time. None of these explanations directly account for a decline in the quality of the measuring instrument.
