Subclaims¶

q3 i2 Post-sleep likeability (d = 0.41) and social willingness to engage (d = 0.50) were higher for the cued than uncued name. → Zhao 2025 q3 i? In an ultimatum game, 77.8% chose the cued person as allocator versus 22.2% for the uncued person (χ²(1) = 16.67, p < 0.001); no standardized effect size was printed. → Zhao 2025 (2)

Evidence¶

Zhao 2025¶

Zhao, H., Lin, X., Yuan, K., Hu, X., Wang, X., Su, W., Wang, Q., & Lu, L. (2025). Updating social evaluation during sleep. npj Science of Learning. https://doi.org/10.1038/s41539-025-00356-9

q3 · i2 · causal · r2

Explicit preference rating test after sleep on a 1–7 scale. Likeability was higher for the cued name (4.21 ± 1.01 vs 3.61 ± 1.10, d = 0.41); social willingness was also higher (4.25 ± 1.18 vs 3.43 ± 1.19, d = 0.50), both significant paired t-tests.

"participants showed a significantly greater degree of likeability and social willingness to engage with the individuals with cued names than those with uncued names (degree of likeability: mean ± SD; cued name: 4.21 ± 1.01; uncued name: 3.61 ± 1.10;t(75) = 3.55,p < 0.001, Cohen’sd=0 . 4 1"

q3 · i? · causal · r2

Single-trial ultimatum game with a hypothetical 500 yuan reward, measuring social trust by allocator choice. "The choice of selecting the individuals with the cued name (77.8%) was significantly greater than that with an uncued name (22.2%)" (Χ²(1) = 16.67, p < 0.001). The article prints no standardized effect size for this contrast.

Related Claims¶

• Mere acoustic name exposure during sleep without positive traits does not enhance mental facial representations of the named person — related
• Sleep cueing with name+positive trait pairs biases trait memory toward more positive and less negative memories of the cued person — related
• Sleep cueing with name+positive trait pairs improves implicit attitudes (IAT D-scores) toward the cued person — related
• Acoustic name+positive trait pair cueing during slow-wave sleep increases the perceived attractiveness of the cued person's mental facial representation — related
• The number of slow oscillations during sleep is positively correlated with attractiveness ratings of faces associated with cued names but not uncued names — related
