Question

Quizplus · Accepted Answer

Practice effects refer to changes in participants' performance that result from repeated exposure to the same measure. This is a particular problem with longitudinal designs, where participants are measured repeatedly over time, as the repeated testing can lead to improvements in performance due to increased familiarity with the measure rather than actual changes in the construct being measured. Cross-sectional designs do not involve repeated testing, so practice effects are less of a concern. Time-lag designs involve measuring different cohorts at different points in time, so practice effects are not relevant. Sequential designs involve combining longitudinal and cross-sectional design elements, so they may be affected by practice effects depending on the specific design.
