Centre for Sleep and Cognition@NUS

New publication. Our first foray into 'Bedtime procrastination'. An area of growing importance, but in need of objective data. We used actigraphy to study adolescent sleep and procrastination @PZhenghao @MRSleepDep @CSC_NUS @SleepHealthEiC @sleepfoundation authors.elsevier.com/sd/article/S23…

6) Comparing the effects of sleep and wake on consolidation of recently acquired schematic knowledge structures. (Hosein Golkashani) #SleepEurope2022

Friday: 4) Evaluation of an incentives-based, mhealth intervention for sleep extension in working adults with short sleep. (Ju Lynn Ong) 5) A 30 min mid-afternoon nap boosts sustained attention and memory encoding. (Andrew Dicom)

Work from our centre will be presented at @ESRS_Sleep. Drop by our posters this week! Wednesday: 1) Systematic review and meta-analyses on the effects of napping on cognition. (Ruth Leong) #SleepEurope2022

Do you use consumer sleep trackers for research? We examined how many nights of data are needed for reliable estimation of sleep. For sleep duration: 3n/week or 5n/month, for sleep variability: 5n/week or 12n/month academic.oup.com/sleepadvances/… led by TeYang Lau @MRSleepDep @CSC_NUS

Excited to go for in-person conference again @ESRS_Sleep. Even more so now the manuscript that goes with the poster is just accepted for pub. "Bedtime procrastination and Chronotype differentially predict adolescent sleep on school nights and non-school nights"

Look out for our latest meta-analysis and review about the cognitive benefits of afternoon naps... kudos to Ruth Leong for putting this together... doi.org/10.1016/j.smrv…

I am looking for a postdoc to start this year or 2023. Candidate should have a PhD in neuroscience, machine learning or related fields. Topics are quite flexible (sites.google.com/view/yeolab/ca…) and up for discussion. Appreciate RT.

We are still recruiting participants for our clinical trial (‘Twinkle’) which will look at sleep and a food supplement. If you are 25-50 years old with sleep complaints, please visit this link to find out more: sleepcognition-lab.org/new-clinical-t…

New paper: "Limited evidence for enhanced working memory performance and effort allocation in the face of loss versus gain incentives: A preregistered (non) replication" Do we really work harder to avoid losses? Led by Christina Chen @luxcytre @PZhenghao onlinelibrary.wiley.com/share/author/P…

1/9 Paper is out rdcu.be/cNHoL Here's some takeaways including new tidbits (good & bad!) since the preprint & even after the paper was accepted. Large sample sizes are helpful for individual-level prediction. We have known that for quite some time, but the recent...

1/2 Don't forget to check out our epic 49-page reviewer response letter! An interesting issue pointed out by the reviewers was that our QC (while standard) led to a sample less representative than the full ABCD sample. Participants with higher quality data were more likely...

In this recent publication on multi-night at-home assessment of novel wearable technologies; we show the promising performance of Gen3 Oura ring and ascertain which age group and sex benefits more from the upgraded algorithms trained on diverse datasets dovepress.com/multi-night-at…

We hope this will be a game-changer for wearable sleep trackers and their use in high-quality longitudinal studies. It took a village to execute this n=58, 3-night at-home study with PSG during COVID-19 🦸‍♂️🦸‍♀️dovepress.com/getfile.php?fi…

We are conducting a clinical trial (‘Twinkle’) which will look at sleep and a food supplement, and are looking for 25-50 year olds with sleep complaints to take part. Interested in finding out more? Please visit this link: sleepcognition-lab.org/new-clinical-t…

How does sleep help the establishment of a knowledge structure and facilitate its transformation as new items replace old ones and other items are added? Check out this article from the talented Dr. Golkashani... doi.org/10.1093/sleep/…
