Observer drift refers to the tendency of raters to drift away from the coding system they were initially trained on, which can lead to inconsistent ratings over time. Observer variance refers to individual differences in rating behavior, while the Hawthorne effect relates to changes in behavior due to being observed. Perceptual shift is not a commonly used term in assessment.
