Five of the seven factors thus evinced were labelled \u2018activation\u2019, \u2018inhibition\u2019, \u2018resilience\u2019, \u2018depressivity-neuroticism\u2019 and \u2018extraversion\u2019, the remaining two factors being related to arousal in an unspecified manner. Although no clear-cut partitioning of variance into trait, state and task-related components was achieved, the contention is advanced that measurement of these factors and their patterning might contribute to psychophysiological diagnosis, provided they are substantiated by further research.<\/jats:p>","DOI":"10.1159\/000283906","type":"journal-article","created":{"date-parts":[[2010,2,8]],"date-time":"2010-02-08T03:31:50Z","timestamp":1265599910000},"page":"88-95","source":"Crossref","is-referenced-by-count":0,"title":["Psychophysiology of the Reaction Time Experiment: A Factor Analytic Approach"],"prefix":"10.1159","author":[{"given":"Fernando","family":"Lolas","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2010,2,5]]},"container-title":["Psychiatria Clinica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/283906","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000283906","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T20:09:20Z","timestamp":1777752560000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000283906"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,2,5]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000283906","archive":["Portico"],"relation":{},"ISSN":["0033-264X","2571-7138"],"issn-type":[{"value":"0033-264X","type":"print"},{"value":"2571-7138","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,2,5]]}}}
