0363 Sound vs. Sight: A Modality-Specific Preliminary Investigation of Sleep-Related Attentional Bias in Older Adults

Abstract Introduction Increased attention to sleep-related stimuli (i.e., “sleep-related attentional bias”) may contribute the persistence of insomnia symptoms. Despite high prevalence disorder in older adults, studies investigating this phenomenon population are lacking. Additionally, it is unclear whether bias occurs only for visual or more broadly, such as auditory stimuli. This study examined and differed a function adults. Methods Sixty-one adults (Mage=68.2±5.9; 41 women/) with (n=22) without (n=39) (met DSM-5 criteria plus reported 6+nights/14 >30 mins sleep onset latency wake after on daily diaries) completed modified Posner Cueing Dot Probe tasks. Task cues included (e.g., alarm clocks, snoring), clocks set bedtimes, person awake bed) non-sleep (auditory: pure tones; visual: neutral images from International Affective Picture system) For Posner, valid [non-cued reaction time (RT) minus validly-cued RT] invalid (non-cued RT invalidly-cued RT) related cueing effects were calculated. Probe, (non-sleep/neutral cued computed. Independent t-tests auditory/visual mean by status. Results larger (p=.04) those (104.6±47.6ms) vs. (80.7±57.3ms). Valid also (p=.001) (118.9±48.8ms) (67.9±77.2ms). there was trending difference (p=.07) between (14.7ms±6.7ms) (-1.8ms±7.1ms). Conclusion Preliminary findings suggest experience than insomnia. Further, greater reflect general cortex hypervigilance. Aging benefit stimulus desensitization towards triggers across sensory modalities potentially facilitate sleep.
