One of the tests put participants in slightly annoying situations — like being faced with a computer malfunction and having to start a tedious task over. The empty-stomached participants were overtly peeved, and later, when given an evaluation of the research assistant’s performance were much likely to give negative feedback, saying that the research assistant had “been judgmental towards them”, Lindquist says, “suggesting that hunger turns up the dial on your anger in the face of a frustrating experience.”
