Quizplus · Accepted Answer

The performance of both groups improving over time suggests maturation, which refers to natural development and growth that occurs with age. The improvement may not necessarily be due to the intervention, but rather to the natural progression and development of the children. Mortality refers to the loss of participants during a study, selection refers to characteristics of participants that may have been present before the intervention, and diffusion refers to the spread of a treatment to participants who were not intended to receive it. None of these options are as applicable to the situation described in the scenario.
