    For example, suppose the treatment is passing an exam, where a grade of 50% is required. In this case, this example is a valid regression discontinuity design so long as grades are somewhat random, due either to the randomness of grading or randomness of student performance.

  3. Developmental stage theories - Wikipedia

    The development of the human mind is complex and a debated subject, and may take place in a continuous or discontinuous fashion. [4] Continuous development, like the height of a child, is measurable and quantitative, while discontinuous development is qualitative, like hair or skin color, where those traits fall only under a few specific phenotypes. [5]

Therefore, developmental psychopathology is not the study of pathological development, but the study of the basic mechanisms that cause developmental pathways to diverge toward pathological or typical outcomes; Development leads to either adaptive or maladaptive outcomes.
