However, while sleep facilitates the consolidation of emotional memories, its influence on emotional reactivity remains unclear. Most prior work has not fully addressed emotional reactivity, often relying solely on subjective or physiological measures, nor has it disentangled the contribution of different sleep stages. Here, using a between\u2010subjects design, we asked participants to complete two picture\u2010based tasks assessing emotional memory and emotional reactivity before and after a manipulation condition (nap,\n                    <jats:italic>N<\/jats:italic>\n                    \u2009=\u200940; wake,\n                    <jats:italic>N<\/jats:italic>\n                    \u2009=\u200940), and again 2\u2009days later. Spontaneous variations in nap duration resulted in participants reaching REM sleep (REM group,\n                    <jats:italic>N<\/jats:italic>\n                    \u2009=\u200920) or not (No\u2010REM group,\n                    <jats:italic>N<\/jats:italic>\n                    \u2009=\u200920). Emotional reactivity, assessed using an emotional picture task consisting of 28 images with different emotional contents (negative and neutral), was measured through subjective ratings and physiological responses (phasic cardiac response and skin conductance response). Sleep preserved memory performance relative to wakefulness, but after 2\u2009days, only negative images maintained a memory advantage in the Nap group; however, no differences emerged as a function of REM sleep occurrence during the nap. For emotional reactivity, subjective arousal decreased after sleep in the REM group, whereas valence ratings declined only after 2\u2009days. Physiologically, heart rate habituation was greater in the No\u2010REM group. Together, these findings indicate that sleep fosters emotional memory consolidation while modulating reactivity in ways that diverge across subjective and physiological domains, with a decrease in subjective arousal ratings and an increase in phasic cardiac response. These findings, which should be interpreted in the context of the observed differences in participants' sleep architecture, highlight the complex role of sleep in emotional processing and underscore the need for standardized experimental paradigms.\n                  <\/jats:p>","DOI":"10.1111\/psyp.70414","type":"journal-article","created":{"date-parts":[[2026,10,16]],"date-time":"2026-10-16T06:11:55Z","timestamp":1792131115000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Emotional Processing in a Nap Paradigm: The Role of Sleep\u00a0Stages in Memory and Reactivity"],"prefix":"10.1111","volume":"63","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-8049-0381","authenticated-orcid":false,"given":"Costanza","family":"Colombo","sequence":"first","affiliation":[{"name":"Department of General Psychology University of Padua  Padua Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-7489-1203","authenticated-orcid":false,"given":"Angie","family":"Baldassarri","sequence":"additional","affiliation":[{"name":"Department of General Psychology University of Padua  Padua Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6286-6569","authenticated-orcid":false,"given":"Umberto","family":"Granziol","sequence":"additional","affiliation":[{"name":"Department of General Psychology University of Padua  Padua Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-8294-3936","authenticated-orcid":false,"given":"Jessica","family":"Ongaro","sequence":"additional","affiliation":[{"name":"Department of General Psychology University of Padua  Padua Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3939-1101","authenticated-orcid":false,"given":"Lorenzo","family":"Viselli","sequence":"additional","affiliation":[{"name":"Department of Biotechnological and Applied Clinical Sciences University of L'Aquila  L'Aquila Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2304-7576","authenticated-orcid":false,"given":"Michele","family":"Ferrara","sequence":"additional","affiliation":[{"name":"Department of Biotechnological and Applied Clinical Sciences University of L'Aquila  L'Aquila Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3650-0683","authenticated-orcid":false,"given":"Aurora","family":"D'Atri","sequence":"additional","affiliation":[{"name":"Department of Biotechnological and Applied Clinical Sciences University of L'Aquila  L'Aquila Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0306-4408","authenticated-orcid":false,"given":"Nicola","family":"Cellini","sequence":"additional","affiliation":[{"name":"Department of General Psychology University of Padua  Padua Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,15]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0191\u20108869(91)90110\u2010W"},{"key":"e_1_2_11_3_1","doi-asserted-by":"crossref","DOI":"10.1002\/9780470594001","volume-title":"Analysis of Ordinal Categorical Data","author":"Agresti A.","year":"2010"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neurobiolaging.2018.03.030"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.3758\/s13415\u2010016\u20100460\u20101"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598\u2010019\u201042478\u20102"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.2532\u201011.2012"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1389\u20109457(00)00065\u20104"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.18637\/jss.v067.i01"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jneumeth.2010.04.028"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuropsychologia.2018.05.015"},{"key":"e_1_2_11_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cortex.2019.07.008"},{"key":"e_1_2_11_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.comppsych.2015.04.005"},{"key":"e_1_2_11_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/0005\u20107916(94)90063\u20109"},{"key":"e_1_2_11_15_1","volume-title":"Handbook of Emotion Elicitation and Assessment","author":"Bradley M.
