Sleep deprivation alters utilization of negative feedback in risky decision-making
Open accessAbstract
Background: Sleep loss has sometimes catastrophic effects on risky decision-making. However, it is unknown to what extent such deficits are exacerbated with increasing duration of sleep deprivation (SD) and whether sustained vigilant attention mediates this sleep deprivation-induced deficit. Methods: The present study aimed to investigate the effect of 36 hours of SD on 37 male college students’ arousal, emotion, vigilant attention, and risky decision-making, using the Psychomotor Vigilance Test, the Game of Dice Task, and scales assessing fatigue, sleep, and emotions. Results: Compared to baseline, SD significantly increased sleepiness, fatigue, and negative emotions, decreased positive emotions and vigilant attention, and led to a shift toward risky decision-making, and these effects often appeared 15 or 20 hours after SD. Interestingly, participants’ ability to employ positive feedback was maintained, whereas their performance to utilize negative feedback was impaired even after 8 hours of sleep deprivation. Meanwhile, vigilant attention acted as a mediator between SD and risky decision-making (z = -1.97, 95% [-6.00, -0.30]). Discussion: These results suggest that sleep-deprived individuals are unable to use negative feedback to optimize their judgments, which may account for their poor decision-making under risk.

TL;DR
In 37 male college students, 36 hours of sleep deprivation increased sleepiness, fatigue, pressure, and negative affect, decreased positive affect and vigilant attention, and shifted decision-making toward risk. Negative feedback use was impaired from 8 hours of sleep deprivation, while positive feedback use was maintained, and vigilant attention partially mediated the sleep deprivation–risky decision-making relationship.
Key findings
- Sleep deprivation significantly increased fatigue [F(6,111)=24.49, p<0.001], sleepiness [F(6,137)=15.60, p<0.001], and pressure [F(6,160)=6.13, p<0.001]; compared with baseline, these were significant at 15, 20, 25, 32, and 36 hours, with the 36th hour highest for fatigue (t=9.56) and sleepiness (t=8.15, p<0.001).
- POMS showed increased negative emotion subscales and decreased positive affect subscales with sleep deprivation (ps<0.01); fatigue and vigor changed significantly from 8 hours, anger and self-esteem from 15 hours, depression from 20 hours, and confusion and tension from 25 hours (ps<0.05).
- PVT reaction times differed across time [F(6,181)=5.20, p<0.001], with significant differences from baseline at 20, 25, 32, and 36 hours (ps<0.01). GDT negative feedback frequency differed across time [F(6,137)=3.01, p<0.01] and was significantly lower than baseline at 8, 15, 20, 25, and 32 hours (ps<0.05); GDT net scores differed across time [F(6,130)=3.15, p<0.01] and were significantly lower than baseline at 20, 32, and 36 hours (ps<0.05). Positive feedback frequency did not change after sleep deprivation.
- Vigilant attention partially mediated the effect of sleep deprivation on risky decision-making (Sobel test, z=-1.97, p<0.05; bias-corrected bootstrap 95% CI [-6.00, -0.30]).
Methods
- Thirty-seven male college students in Beijing, China (age 23.18 ± 1.98; BMI 21.50 ± 3.04), with no history of mental health, neurological, or organic disease; participants kept a regular sleep schedule and refrained from alcohol, caffeine, and chocolate for at least 1 week before the study.
- In-laboratory 36-hour sleep deprivation from 7:00 AM, with measures at baseline, 8, 15, 20, 25, 32, and 36 hours: Stanford Sleepiness Scale, stress/fatigue ratings, abbreviated Profile of Mood States, 5-minute Psychomotor Vigilance Test (50 trials), and Game of Dice Task (18 rounds with explicit gain/loss rules).
- Mixed linear models with AR(1) covariance, time as a fixed effect, random intercept, and LSD post hoc comparisons; correlation/partial correlation analyses; mediation analysis using MEMORE Model 1 for two-instance repeated measures with 5,000 bootstrap resamples.
Limitations
- The paper states that the number of participants was limited due to the long experiment and many test items, so the mediation effect of vigilant attention is exploratory; subjective scales were sensitive within subjects but between-subject differences were small, reducing correlations with other indicators; and the college-student sample has low ecological validity, with future research needed in workers, doctors, and other groups.
- Evident from the text: the study used a single-arm, within-subject design without a non-sleep-deprived control group, and only male participants were included, limiting generalizability to women.

It may state two separate claims as one.
The authors state this as an assumption.
It is unknown to what extent sleep deprivation-induced deficits in risky decision-making are exacerbated with increasing duration of sleep deprivation and whether sustained vigilant attention mediates this deficit.
“However, it is unknown to what extent such deficits are exacerbated with increasing duration of sleep deprivation (SD) and whether sustained vigilant attention mediates this sleep deprivation-induced deficit.”
The authors state this as an assumption.
Few previous studies collected data multiple times during sleep deprivation due to the complexity of the sleep deprivation process and the negative emotions of participants.
“According to a summary of previous studies, few studies collected data multiple times due to the complexity of the SD process and the negative emotions of the participants.”
The paper relies on this without support.
Attention, memory, thinking, and other cognitive capabilities must work together to make risky choices.

The paper relies on this without support.
When people rely too much on their intuition, they frequently have a propensity to ignore or undervalue the dangers that could come with losses because they are more concerned with the possibility of maximizing rewards.

Statistics recomputed
Every reported test result, recomputed from its test statistic and degrees of freedom. A result shows as not adding up only once an independent check has confirmed it.
- ConsistentF(6, 111) = 24.49reported p < .001 · recomputed p < .001
“F(6,111)=24.49, p < .001”

Self-check
Percentages, sums and reported differences re-computed from the paper’s own numbers.
Each contradiction between two passages listed here was confirmed by an independent check.
Rated minor: it would not touch a result — a value no result rests on, a p-value that stays on the same side of the significance level, or a conflict that is clerical, resolved elsewhere in the paper, or outside its own findings.
In the paper
§ Sleep deprivation alters utilization of negative feedback in risky decision-making > Results > Affect response
“the Pearson correlation coefficient of two subscales related to positive emotion (i.e., vigor and tension) was significant after 36 hours of SD (p<0.01).”
§ Sleep deprivation alters utilization of negative feedback in risky decision-making > Results > Affect response
“an increase of five subscales related to negative emotion (tension, fatigue, anger, depression, and confusion; ps<0.01) and a decrease of two subscales of positive affection (vigor and esteem-related affect; ps<0.01)”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-11-11, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-11-11 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
