To this end, we combined classic self-reported measures of sensory aspects, preferences, environmental attitudes, and consumption habits together with physiological measures of cognitive\u2013emotional processing. Three different materials\u2014two recycled materials, M2 and M3, and one raw material, M1\u2014were chosen for inspection through three different sensory conditions, which we refer to as channels \u2014visual, tactile, and visuo-tactile. The assignation of materials to sensory channels was counterbalanced so that each participant evaluated only one of the materials per channel. Although participants in general were not very accurate in discriminating between the materials, self-reported sensory evaluations showed that M3 (a recycled material that is made to look non-recycled), was clearly less liked. Meanwhile, the psychophysiological analyses revealed higher levels of electrodermal activity for the tactile evaluations of both recycled materials (M2 and M3). Finally, the results from the attitudes and habits evaluations indicate that the participants had positive environmental attitudes yet poor consumption habits. Altogether, these results suggest that some sensorial properties differ between recycled materials and natural raw materials and that there is a chance to improve and implement new consumption habits. The implications of these results are further discussed both in terms of suggestions for designers and methodological recommendations for researchers.<\/jats:p>","DOI":"10.3390\/s22239226","type":"journal-article","created":{"date-parts":[[2022,11,28]],"date-time":"2022-11-28T08:13:09Z","timestamp":1669623189000},"page":"9226","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Perception of Recycled Plastics for Improved Consumer Acceptance through Self-Reported and Physiological Measures"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6375-0317","authenticated-orcid":false,"given":"Ainoa","family":"Abella","sequence":"first","affiliation":[{"name":"ELISAVA, Barcelona School of Design and Engineering, UVIC-UCC, La Rambla 30-32, 08002 Barcelona, Spain"},{"name":"Department of Statistics and Operations Research, Universitat Polit\u00e8cnica de Catalunya | BarcelonaTech, Avinguda Diagonal, 647, 08028 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1162-8162","authenticated-orcid":false,"given":"Pere","family":"Llorach-Massana","sequence":"additional","affiliation":[{"name":"ELISAVA, Barcelona School of Design and Engineering, UVIC-UCC, La Rambla 30-32, 08002 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1145-146X","authenticated-orcid":false,"given":"Alexandre","family":"Pereda-Ba\u00f1os","sequence":"additional","affiliation":[{"name":"Eurecat, Centre Tecnol\u00f2gic de Catalunya, C\/Bilbao, 72, 08018 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0440-1675","authenticated-orcid":false,"given":"Llu\u00eds","family":"Marco-Almagro","sequence":"additional","affiliation":[{"name":"Department of Statistics and Operations Research, Universitat Polit\u00e8cnica de Catalunya | BarcelonaTech, Avinguda Diagonal, 647, 08028 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miguel","family":"Barreda-\u00c1ngeles","sequence":"additional","affiliation":[{"name":"Eurecat, Centre Tecnol\u00f2gic de Catalunya, C\/Bilbao, 72, 08018 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura","family":"Cl\u00e8ries","sequence":"additional","affiliation":[{"name":"ELISAVA, Barcelona School of Design and Engineering, UVIC-UCC, La Rambla 30-32, 08002 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e1700782","DOI":"10.1126\/sciadv.1700782","article-title":"Production, use, and fate of all plastics ever made","volume":"3","author":"Geyer","year":"2017","journal-title":"Sci.
