Scientists have yet to have their own \u201caha\u201d moment of insight on how it might work, though sleep appears to play a role.<\/p>\n<p>To better understand how sleep might lead to insight while problem-solving, the authors of this pre-registered study asked\u00a090 people to track a series of dots across a screen.<\/p>\n<p>The participants were given instructions about a seemingly simple task that merely involved responding to the dots on a keyboard, but the instructions left out a trick that could make the task easier.<\/p>\n<p>After four sets of trials, the subjects were put down for a 20-minute nap, hooked up to an electroencephalogram (EEG) to track their sleep.<\/p>\n<p>After their nap, the subjects were tested again, and 70.6 percent of participants had their \u201caha\u201d moment, figuring out the unmentioned trick that made the task easier. All groups improved after their rest period, but 85.7 percent of those who achieved the first deeper sleep phase\u2014called N2 sleep\u2014had their breakthrough.<\/p>\n<p>In contrast, 55.5 percent of those who stayed awake and 63.6 of those who dropped into light, N1 sleep experienced a moment of insight. Studies of the EEG patterns showed that a steeper spectral slope, associated with deeper sleep, was also associated with an \u201caha\u201d moment.<\/p>\n<p>While the study did not compare people who rested or napped to those who didn\u2019t get a break, a previous study by the authors that used the same task (but did not give participants a chance to nap) found 49.6% experienced \u201caha\u201d moments. Thus, the authors suggest that a nap with deeper, N2 sleep might help someone who needs a moment of insight.<\/p>\n<p>Coauthor Nicolas Schuck notes, \u201cIt\u2019s really intriguing that a short period of sleep can help humans make connections they didn\u2019t see before. The next big question is why this happens. We hope that our discovery that it may be linked to the EEG spectral slope is a good first lead.\u201d<\/p>\n<p>Anika L\u00f6we says, \u201cThe EEG spectral slope has only recently been considered as a factor in cognitive processes during sleep. I find the link between the spectral slope steepness during sleep, aha-moments after sleep and the down regulation of weights \u2013 which we identified as crucial for aha-moments in our previous computational work \u2013 very exciting.\u201d<\/p>\n<p>L\u00f6we adds, \u201cI think a lot of us have made the subjective experience of having important realizations after a short nap. It\u2019s really nice to not only have data on that, but also a first direction of what processes are behind this phenomenon.\u201d<\/p>\n<p>L\u00f6we concludes, \u201cWhat really struck me when telling people in my environment \u2013 particularly creatives \u2013 about these findings was how much they resonated with people. Many of them could relate to our results with a personal experience of having a (creative) breakthrough after a nap.\u201d<\/p>\n<p><strong>Funding:\u00a0<\/strong>ATL is supported by the International Max Planck Research School on Computational Methods in Psychiatry and Ageing Research (IMPRS COMP2PSYCH,\u00a0www.mps.ucl-centre.mpg.de).<\/p>\n<p>NWS was funded by the Federal Government of Germany and the State of Hamburg as part of the Excellence Initiative, a Starting Grant from the European Union (ERC-StG-REPLAY-852669), and an Independent Max Planck Research Group grant awarded by the Max Planck Society (M.TN.A.BILD0004).

PLOS Biology<\/p>\n<p><strong>Abstract<\/strong><\/p>\n<p><strong>N2 sleep promotes the occurrence of \u2018aha\u2019 moments in a perceptual insight task<\/strong><\/p>\n<p>Humans sometimes have an insight that leads to a sudden and drastic performance improvement on the task they are working on.<\/p>\n<p>The precise origins of such insights are unknown. Some evidence has shown that sleep facilitates insights, while other work has not found such a relationship.<\/p>\n<p>One recent suggestion that could explain this mixed evidence is that different sleep stages have differential effects on insight. In addition, computational work has suggested that neural variability and regularisation play a role in increasing the likelihood of insight.<\/p>\n<p>To investigate the link between insight and different sleep stages as well as regularisation, we conducted a preregistered study in which N=90 participants performed a perceptual insight task before and after a 20 minute daytime nap.<\/p>\n<p>Sleep EEG data showed that N2 sleep, but not N1 sleep, increases the likelihood of insight after a nap, suggesting a specific role of deeper sleep.<\/p>\n<p>Exploratory analyses of EEG power spectra showed that spectral slopes could predict insight beyond sleep stages, which is broadly in line with theoretical suggestions of a link between insight and regularisation.<\/p>\n<p>In combination, our findings point towards a role of N2 sleep and aperiodic, but not oscillatory, neural activity for insight.<\/p>\n","protected":false},"excerpt":{"rendered":"Summary: A new study suggests that a short nap, especially one reaching deeper N2 sleep, can significantly boost&hellip;\n","protected":false},"author":3,"featured_media":18644,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[11],"tags":[827,17714,210,17715,829,831,17716,17717,17718,1079,67,132,68],"class_list":["post-18643","post","type-post","status-publish","format-standard","has-post-thumbnail","category-health","tag-brain-research","tag-creativity","tag-health","tag-napping","tag-neurobiology","tag-neuroscience","tag-open-access","tag-open-science","tag-plos","tag-sleep","tag-united-states","tag-unitedstates","tag-us"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@us\/114754510294240987","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/18643","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/comments?post=18643"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/18643\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media\/18644"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media?parent=18643"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/categories?post=18643"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/tags?post=18643"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
