Two experiments were conducted to examine the effect of hunger on fini
ckiness in humans. Subjects (a total of 157 undergraduate female diete
rs and non-dieters) were food-deprived and then subsequently either gi
ven a snack (not-hungry group) or left food-deprived (hungry group) be
fore being given ad libitum access to either good-tasting or bad-tasti
ng (quinine-adultered) milkshake. Common sense predicted that hungry s
ubjects would drink more milkshake than would not-hungry subjects, reg
ardless of milkshake palatability. Hungry subjects did in fact drink m
ore of the good-tasting milkshake than did not-hungry subjects, but th
ey also drank less of the bad-tasting milkshake. We discuss possible r
easons why hunger might increase rejection of bad-tasting food, as wel
l as the limiting conditions of the effect.
