Notes

• Not the same as response_count, which counts the pieces of ONE response: a digit-span trial recalling "3-5-7" has response_count = 3 but subtrial_count = 1 (one stimulus, one recall, one evaluation), while a two-step trial has subtrial_count = 2 (two stages, each with its own stimulus and outcome).
