Subclaims¶

q3 i3 A significant three-way interaction of time, valence, and face type on trait memory (F(1, 53) = 15.00, η²p = 0.22), with post-sleep simple effects showing more positive (d = 0.68) and fewer negative (d = −0.36) memories for the cued than uncued name. → Zhao 2025 q3 i? No participant recalled any positive trait played during sleep, indicating cues were processed unconsciously. → Zhao 2025 (2)

q3 · i3 · causal · r2

Repeated-measures 2×2×2 ANOVA on memory bias (face type × valence × time) in the nap experiment. A "significant three-way interaction effect among time, valence, and face type" (F(1, 53) = 15.00, p < 0.001, η²p = 0.22) was followed by simple effects showing post-sleep more positive memories for the cued name (d = 0.68) and fewer negative (d = −0.36).

"we detected a significant three-way interaction effect among time, valence, and face type, F(1, 53) = 15.00, p < 0.001, η²p =0 . 2 2"

q3 · i? · causal · r2

Awareness check in the same nap experiment: participants reported zero recollections of sleep-played traits, which the authors take to show "the cues were processed unconsciously without entering conscious awareness". Note the sleep-played traits differed from the pre-sleep learned traits that were tested.

"none of the participants recalled any of the positive traits presented during sleep, as indicated by zero reports of the traits played during sleep in the memory test"

Discussion¶

Related Claims¶

• Mere acoustic name exposure during sleep without positive traits does not enhance mental facial representations of the named 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
• Sleep cueing with name+positive trait pairs improves implicit attitudes (IAT D-scores) toward 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
• The number of slow oscillations during sleep is positively correlated with attractiveness ratings of faces associated with cued names but not uncued names — related
