Subgroup Constraints on Reactive (Re) and Proactive (Pro) Motive Scores for the Pure and Predominant Versions of the Reactive Only and Both Subtypes Hypotheses

	Reactive subgroup	Mixed subgroup	Proactive subgroup
Reactive only – pure	Re > 0; Pro = 0	Re > 0; Pro > 0
Reactive only – predominant	Re > Pro*1.5	Re ≤ Pro*1.5
Both subtypes – pure	Re > 0; Pro = 0	Re > 0; Pro > 0	Re = 0; Pro > 0
Both subtypes – predominant	Re > Pro*1.5	Highest / lowest ≤ 1.5a	Pro > Re*1.5

^aThe mixed subgroup of the both subtypes – predominant hypothesis includes children for whom the ratio between their highest and lowest motive score is less than or equal to 1.5
