Randomization is actually a technique used to control for threats to internal validity, so it is not considered a threat itself. Maturation refers to changes in participants over time that would impact the results, instrumentation refers to changes in the measuring instruments or tools used, and statistical regression refers to the tendency for extreme scores to move closer to the mean in subsequent measurements. These are all potential threats to internal validity that must be controlled for in experimental designs.
