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. info:eu-repo/grantAgreement/ES/FIS/PI12-00514 info:eu-repo/grantAgreement/ES/MINECO/TIN2014-5356-R info:eu-repo/grantAgreement/ES/UZ/PIFUZ2011-TRCA-003 info:eu-repo/grantAgreement/ES/UZ/UZ2014-TEC-01 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0001-8742-0072 Lázaro, Jesús Universidad de Zaragoza Arza, Adriana Garzón, Jorge Mario (orcid)0000-0001-7285-0715 Gil, Edurado Universidad de Zaragoza (orcid)0000-0003-3434-9254 Laguna, Pablo.
