I'm literally appalled that they used this method of study. They put kids between the ages of three and eight, when their minds are still developing and they're still learning about  how the world works, through an intentionally stressful and upsetting test? And they didn't think that perhaps that would be literally traumatic to a THREE YEAR OLD, and could genuinely change the way they perceive certain environments and topics for literally years? This is incredibly unethical, and I absolutely can't believe that anyone signed off on it -- researchers, parents, and oversight just let this happen. Traumatizing kids is the easiest way to induce internalized disorders in the future, and I'm incredibly concerned by the potential ramifications of this test.
