In unilateral pitch ranking, subjects judge which of two successive stimuli is higher in pitch, typically yielding electrode order roughly consistent with tonotopy. In our study with 10 MED-EL CI users, each of the 12 electrodes was compared with its three next neighbors. Pitch ranking was influenced by the presentation order of the electrode pairs. To investigate this effect, we tested 9 normal-hearing (NH) listeners using bandpass-filtered noise (6\u2005dB\/oct slopes) to approximate current spread during CI stimulation. Comparable performances across CI and NH in all three spacing conditions indicated similar pitch perception difficulty. On average, both groups discriminated 8 of 12 channels based solely on pitch (discriminability via d\u2019), suggesting that 6\u2005dB\/oct slopes approximate mean monopolar current spread at the group level. Pitch rankings of adjacent channels exhibited biases. A repeated-measures ANOVA revealed a significant interaction between presentation order and stimulation site in both groups (CI: p\u2009=\u2009.003; NH: p\u2009&lt;\u2009.001): pairs below the stimulus range midpoint were more often reported as descending, whereas pairs above the middle were more often reported as ascending. This asymmetric bias may reflect a context-dependent decision process in which subjects compare the second stimulus to a weighted average of the first and previously presented stimuli. Presentation-order effects were mitigated by testing stimulus pairs in isolation, at the expense of reduced randomization. Our findings highlight the importance of controlling biases to ensure reliable psychophysical measures.<\/jats:p>","DOI":"10.1177\/23312165261447074","type":"journal-article","created":{"date-parts":[[2026,7,15]],"date-time":"2026-07-15T07:45:16Z","timestamp":1784101516000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Impact of Presentation Order on Pitch Ranking Sensitivity in Cochlear Implant Users and Normal-Hearing Listeners and Its Mitigation"],"prefix":"10.1177","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6759-1250","authenticated-orcid":false,"given":"Carmen Marie","family":"Casta\u00f1eda Gonz\u00e1lez","sequence":"first","affiliation":[{"name":"Munich Institute of Biomedical Engineering, Technical University of Munich"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manuela","family":"Huber","sequence":"additional","affiliation":[{"name":"Munich Institute of Biomedical Engineering, Technical University of Munich"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Florian","family":"V\u00f6lk","sequence":"additional","affiliation":[{"name":"Munich Institute of Biomedical Engineering, Technical University of Munich"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-9965-7323","authenticated-orcid":false,"given":"Louis","family":"Teufel","sequence":"additional","affiliation":[{"name":"Munich Institute of Biomedical Engineering, Technical University of Munich"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-1222-4584","authenticated-orcid":false,"given":"Aulia","family":"Djamal","sequence":"additional","affiliation":[{"name":"Munich Institute of Biomedical Engineering, Technical University of Munich"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-6917-7205","authenticated-orcid":false,"given":"Linya","family":"Ruan","sequence":"additional","affiliation":[{"name":"Munich Institute of Biomedical Engineering, Technical University of Munich"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Skander","family":"Znaidi","sequence":"additional","affiliation":[{"name":"Munich Institute of Biomedical Engineering, Technical University of Munich"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2905-6118","authenticated-orcid":false,"given":"Werner","family":"Hemmert","sequence":"additional","affiliation":[{"name":"Munich Institute of Biomedical Engineering, Technical University of Munich"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sonja","family":"Karg","sequence":"additional","affiliation":[{"name":"Technical University of Ingolstadt"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,7,15]]},"reference":[{"key":"e_1_3_3_2_1","doi-asserted-by":"publisher","DOI":"10.3389\/fnins.2019.01119"},{"key":"e_1_3_3_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003446-200406000-00008"},{"key":"e_1_3_3_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.heares.2005.12.010"},{"key":"e_1_3_3_5_1","volume-title":"Acoustic Measurements","author":"Beranek L.
