Subclaims¶

q3 i2 Implicit attitude toward the cued name improved significantly after sleep cueing relative to the uncued name (d = 0.40). → Zhao 2025

q3 · i2 · causal · r2

Paired-sample t-test on IAT D600 scores before and after sleep cueing in the nap experiment. Mean implicit attitude shifted "before sleep: 0.00 ± 0.64; after sleep: 0.18 ± 0.67" (t(75) = 3.50, p < 0.001, Cohen's d = 0.40), favoring the cued name.

"we found a significantly improved implicit attitude toward the cued name compared with the uncued name after sleep (mean ±SD; before sleep: 0.00 ± 0.64; after sleep: 0.18 ± 0.67;t(75) = 3.50,p <0 . 0 0 1 ,C o h e n’sd=0 . 4 0 )"

Discussion¶

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 explicit attitudes: likeability, social willingness, and trust choices favor 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
