I'm going to guess that psychology research is far less expensive. To give you a sense of perspective here, $25k will get you something like 4 months of a full time employee at the "fresh out of college" experience level, including benefits and research consumables. That also assumes that you have all of the equipment in place. If all there doing is running a few western blots, because that's all they can do on this budget, well then ok. But I'll venture to guess that that's a far cry from reproducing the most important results in these papers.
