Long-term memory

Does 'don't lose points' change what we choose to remember?

When a memory task was framed as avoiding losses instead of earning points, people focused slightly less on remembering the most valuable words.

Study at a glance

Design
Human experiment — Between-subjects gain vs loss framing of point values attached to words to be recalled; Experiment 1 used fixed study time with judgments of learning, Experiment 2 self-paced study with judgments, and Experiment 3 crossed framing with fixed vs self-paced study without judgments.
N
107 students in Experiment 1, 107 in Experiment 2 and 354 in Experiment 3, all after exclusions; separate participants in each experiment.
Population
Undergraduate students from a US university subject pool, tested online.
Outcome
Item-level free recall as a function of word value (selectivity), judgments of learning, and self-paced study time, compared between gain- and loss-framed groups.

Key findings

Overall recall was similar under both framings (roughly 44-46% of words), but value predicted recall more strongly in the gain-framed group, meaning gain framing made memory more selective for high-value words; this interaction was significant in Experiments 1 and 3 but only a weak trend in Experiment 2. Participants' predictions of their memory mirrored this pattern, showing they were aware of their selectivity. Framing did not change how people allocated self-paced study time to high- versus low-value words, and self-pacing did not remove the framing effect.

Methodology

Students studied lists of 20 words, each paired with a point value from 1 to 20, and then freely recalled each list, over six study-test rounds. One group was told they would earn each word's points if they remembered it and got feedback on points scored; the other was told they would lose each word's points if they forgot it and got feedback on points lost. Across the experiments, the authors varied whether study time was fixed or self-paced and whether participants predicted their own memory for each word.

Limitations

The framing effect on selectivity was small, and it did not reach significance in Experiment 2, so it should be seen as a subtle shift rather than a large change in memory. Points had no real consequences and testing was unsupervised online, so it is unclear whether real money, grades or life-relevant stakes (such as remembering allergies) would produce the same pattern; the authors call for lab and incentive-based follow-ups. The study also does not identify the mechanism, since neither study-time allocation nor metacognitive judgments explained the effect.
