Practice effects refer to the improvements in performance resulting from repeated exposure to a task or test, which can confound the assessment of true learning or cognitive change over time. They are a critical consideration in longitudinal studies, cognitive testing, and educational assessments, where distinguishing between genuine skill acquisition and mere familiarity with the test is essential.

Longitudinal studies are research designs that involve repeated observations of the same variables over extended periods, allowing researchers to detect developments or changes in the target population. They are particularly useful for studying long-term effects and causal relationships, providing insights that cross-sectional studies cannot offer.

Cognitive testing evaluates mental functions such as memory, reasoning, and problem-solving to understand an individual's cognitive abilities and potential impairments. It is widely used in educational, clinical, and research settings to diagnose conditions, guide interventions, and track cognitive development or decline.
