Recent studies showed that when making trust decisions in economic games, people have some accuracy in detecting trustworthiness from the facial features of unknown partners. Here we provide evidence that this face-based trustworthiness detection is a fast and intuitive process by testing its performance at split-second levels of exposure. Participants played a Trust game, in which they made decisions whether to trust another player based on their picture. In two studies, we manipulated the exposure time of the picture. We observed that trustworthiness detection remained better than chance for exposure times as short as 100 ms, although it disappeared with an exposure time of 33ms. We discuss implications for ongoing debates on the use of facial inferences for social and economic decisions. date: 2017 date_type: published publisher: Hogrefe & Huber id_number: 10.1027/1618-3169/a000367 official_url: http://tse-fr.eu/pub/31548 faculty: tse divisions: tse divisions: CRM keywords: trustworthiness detection keywords: split-second keywords: trust game language: en has_fulltext: FALSE doi: 10.1027/1618-3169/a000367 subjectsJEL: JEL_C91 subjectsJEL: JEL_D03 view_date_year: 2017 full_text_status: none publication: Experimental Psychology volume: 64 number: 4 pagerange: 231-239 refereed: TRUE issn: 1618-3169 oai_identifier: oai:tse-fr.eu:31548 harvester_local_overwrite: divisions harvester_local_overwrite: faculty harvester_local_overwrite: oai_set harvester_local_overwrite: issn harvester_local_overwrite: publisher harvester_local_overwrite: creators_affiliation harvester_local_overwrite: id_number harvester_local_overwrite: doi harvester_local_overwrite: creators_idrefppn oai_lastmod: 2024-04-15T14:53:40Z oai_set: tse oai_set: ut1c site: ut1 citation: Bonnefon, Jean-François , De Neys, Wim and Hopfensitz, Astrid (2017) Split-second trustworthiness detection from faces in an economic game.
