研究问题
However, these findings may be primarily based on data from White adults, as demographic information was omitted from most studies.；However, the impact of poor sleep on episodic memory performance is unclear in minoritized racial and ethnic groups across the adult lifespan, and potential interactions with age-related declines in sleep quality and memory performance are understudied.；Given that familiarity-based recognition memory lacks contextual, episodic details, we hypothesized that these results suggest poorer sleep quality is linked with greater reliance on familiarity-based recognition (i.e., lacking episodic integrity) in minoritized racial and ethnic groups.
方法
Participants in the present analysis were categorized as Black (non-Hispanic Black), and White (non-Hispanic White) according to their self-selected racial and ethnic categorization.；We recruited participants online using Prolific ().；All participants were U.S. residents with sufficient eyesight to see a computer screen and proficient in the English language.；Two hundred seventy-eight participants completed all tasks required to measure episodic memory retention.
核心结论
Memory retention for non-interference pairs was lower than memory performance for interference pairs, but these differences were not statistically significant across interference conditions (see ; t213 = 0.81, p = 0.21).；Because we found no reliable differences between memory retention for interference pairs as compared to non-interference conditions, we collapsed across interference conditions for subsequent analyses.；Black adults showed significant associations between poorer sleep quality and poorer memory performance (i.e., lower retention scores), but not White adults (See and ). ‖ 结论：Taken together, depression, poor sleep quality, and discrimination are interrelated and may influence stronger sleep-memory associations in Black adults than White adults.
局限
This study is the first experimental study to demonstrate that these associations are also observed with self-reported sleep quality and memory retention, which suggests associative memory retention is more sensitive to sleep quality in Black adults than White adults.；Differing from previous research only assessing racial and ethnic differences in sleep-memory associations (; ), the present study aimed to examine racially patterned stressors, including self-reported discrimination and related depressive symptoms, that may exacerbate the association between poorer sleep quality and poorer memory retention in Black adults.；Here, we extended this research by assessing self-reported discriminati
