Clinical studies indicated that HRA measures have additive clinical value over the more frequently used HRV indexes. Despite the abundance of studies on psychological influences on HRV, little is known whether psychological factors influence HRA. Based on previous research regarding HRA and stress, we expected that negative emotions compared to positive emotions would decrease the contribution of decelerations to HRV. Thirty female participants watched three clips that produced negative emotions, positive emotions, and neutral affect. Besides electrocardiogram, we measured several physiological and behavioral responses to ascertain the affective impact of the clips. Using the RR interval time series, we calculated HRV and HRA indexes. We found that HRA differentiated between positive emotions and negative emotions reactivity. Positive emotions produced a higher number of decelerations in short\u2010term variability to the total short\u2010term variability (<jats:italic>C<\/jats:italic>1<jats:italic><jats:sub>d<\/jats:sub><\/jats:italic>) compared to negative emotions. Moreover,<jats:italic>C<\/jats:italic>1<jats:italic><jats:sub>d<\/jats:sub><\/jats:italic>correlated with subjective ratings of affect. In sum, the results of this study indicated that HRA is sensitive to psychological influences. HRA indexes are likely to contribute to a more nuanced physiological differentiation between emotions.<\/jats:p>","DOI":"10.1111\/psyp.13318","type":"journal-article","created":{"date-parts":[[2019,1,17]],"date-time":"2019-01-17T19:11:27Z","timestamp":1547752287000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Effects of emotions on heart rate asymmetry"],"prefix":"10.1111","volume":"56","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5565-8334","authenticated-orcid":false,"given":"Lukasz D.","family":"Kaczmarek","sequence":"first","affiliation":[{"name":"Faculty of Social Sciences, Institute of Psychology Adam Mickiewicz University Poznan Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maciej","family":"Behnke","sequence":"additional","affiliation":[{"name":"Faculty of Social Sciences, Institute of Psychology Adam Mickiewicz University Poznan Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jolanta","family":"Enko","sequence":"additional","affiliation":[{"name":"Faculty of Social Sciences, Institute of Psychology Adam Mickiewicz University Poznan Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Micha\u0142","family":"Kosakowski","sequence":"additional","affiliation":[{"name":"Faculty of Social Sciences, Institute of Psychology Adam Mickiewicz University Poznan Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian M.","family":"Hughes","sequence":"additional","affiliation":[{"name":"School of Psychology National University of Ireland Galway Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaroslaw","family":"Piskorski","sequence":"additional","affiliation":[{"name":"Faculty of Physics and Astronomy University of Zielona G\u00f3ra Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Przemys\u0142aw","family":"Guzik","sequence":"additional","affiliation":[{"name":"Department of Cardiology Intensive Care Therapy and Internal Medicine Poznan University of Medical Science Poznan Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,1,17]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1037\/1089-2680.10.3.229"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1152\/ajpheart.01283.2008"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(06)68735-7"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.2517-6161.1995.tb02031.x"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.85.1.164"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1109\/10.959330"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1038\/sj.ijo.0803353"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1037\/a0018534"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.psy.0000221378.09239.6a"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/1469-8986.3740543"},{"key":"e_1_2_6_12_1","first-page":"589","article-title":"The FaceReader: Online facial expression recognition","volume":"30","author":"Uyl M.
