This was the only semi-constructive reply at physicsforums.com:
I say this as someone who's forte is cognitive neuroscience, not physics. |
I'm extremely skeptical; I can think of no possible mechanism by which this effect could have occurred. If we assume for a moment that the direction of attention could collapse a wave function, then this would not be the proper way to design an experiment to test it. When attention tasks like the one here are performed in functional neuroimaging experiments, you have to go to great lengths to design control tasks for the simple reason people can't actually "withdraw" their attention on command ("stop thinking of the purple elephant"). If you wanted to do this experiment properly (and there a few ways you could do it), you could, say, have two slit apparatuses on opposite sides of the rooms and have participants switch their focus between them. Another way would be to have the slit apparatus and an entirely different by equally exotic looking machine between which the participants could switch their attention. "Slit" and "nothing" is poor design.
Even if the experiment were designed properly, I'd apply Bayes' theorem and conclude that the prior probability of the effect being real was too remote to conclude anything.
