Hunger motivates people to consume food, for which finding and acquiring food is
a prerequisite. We test whether the acquisition component spills over to nonfood
objects: Are hungry people more likely to acquire objects that cannot satisfy
their hunger? Five laboratory and field studies show that hunger increases the
accessibility of acquisition-related concepts and the intention to acquire not
only food but also nonfood objects. Moreover, people act on this intention and
acquire more nonfood objects (e.g., binder clips) when they are hungry, both when
these items are freely available and when they must be paid for. However, hunger
does not influence how much they like nonfood objects. We conclude that a basic
biologically based motivation can affect substantively unrelated behaviors that
cannot satisfy the motivation. This presumably occurs because hunger renders
acquisition-related concepts and behaviors more accessible, which influences
decisions in situations to which they can be applied.
