Changing the terms of the test in the middle of it, without warning, is disruptive. I’m not convinced it “fried their brains.” The same would happen with a calculator suddenly removed during the middle of an exam.
Or any task change really. You tell me that I’m here for a writing task, then halfway through it becomes a math test? There’s no way I’m doing anywhere near as well as if they told me what was happening ahead of time.

You are disregarding the last paragraph, where 2 other studies showed similar results, without having the “disruptive” factor.
