This article investigates how people's metacognitive judgments influence su
bsequent study-time-allocation strategies. The authors present a comprehens
ive literature review indicating that people allocate more study time to ju
dged-difficult than to judged-easy items-consistent with extant models of s
tudy-time allocation. However, typically, the materials were short, and par
ticipants had ample time for study. In contrast, in Experiment 1, when part
icipants had insufficient time to study, they allocated more time to the ju
dged-easy items than to the judged-difficult items, especially when expecti
ng a test. In Experiment 2, when the materials were shorter, people allocat
ed more study time to the judged-difficult materials. In Experiment 3, unde
r high time pressure, people preferred studying judged-easy sonnets; under
moderate time pressure, they showed no preference. These results provide ne
w evidence against extant theories of study-time allocation.
