The following stages in the test were analyzed: the pre-relaxing stage, the story telling stage, the anticipation of stress and the video exposition stage. Respiration signal is recorded during the whole test using a thoracic band. Power spectral density (PSD) of respiration is computed in running windows using a modification of Welch periodogram in which sufficiently peaked spectra are averaged. Then, respiratory frequency (FR) is estimated from the peaked-conditioned averaged spectra. Results show that respiratory rate is significantly (p < 0.05 according to the Friedman test) higher, while a measure of spectral peakness and the percentage of PSD used to compute (FR) is lower during stress stages than during relax. These results suggest that the respiration-related parameters have potential discrimination power for stress level assessment. 000063102 536__ $$9info:eu-repo/grantAgreement/ES/FIS/PI12-00514$$9info:eu-repo/grantAgreement/ES/MINECO/TIN2014-5356-R$$9info:eu-repo/grantAgreement/ES/UZ/PIFUZ2011-TRCA-003$$9info:eu-repo/grantAgreement/ES/UZ/UZ2014-TEC-01 000063102 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000063102 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000063102 700__ $$0(orcid)0000-0001-8742-0072$$aLázaro, Jesús$$uUniversidad de Zaragoza 000063102 700__ $$aArza, Adriana 000063102 700__ $$aGarzón, Jorge Mario 000063102 700__ $$0(orcid)0000-0001-7285-0715$$aGil, Edurado$$uUniversidad de Zaragoza 000063102 700__ $$0(orcid)0000-0003-3434-9254$$aLaguna, Pablo.$$uUniversidad de Zaragoza 000063102 700__ $$aAguiló, Jordi 000063102 700__ $$0(orcid)0000-0003-1272-0550$$aBailón, Raquel$$uUniversidad de Zaragoza 000063102 7102_ $$15007$$2520$$aUniversidad de Zaragoza$$bDpto.
