To probe magnocellular function, various psychophysical tasks are often employed that require the processing of rapidly changing stimuli. But is performance on these several tasks supported by a common substrate? To answer this question, we tested a cohort of 1060 individuals on four \u2018magnocellular tasks\u2019: detection of low-spatial-frequency gratings reversing in contrast at a high temporal frequency (so-called\n            <jats:italic>frequency-doubled<\/jats:italic>\n            gratings); detection of pulsed low-spatial-frequency gratings on a steady luminance pedestal; detection of coherent motion; and auditory discrimination of temporal order. Although all tasks showed test\u2013retest reliability, only one pair shared more than 4 per cent of variance. Correlations within the set of \u2018magnocellular tasks\u2019 were similar to the correlations between those tasks and a \u2018non-magnocellular task\u2019, and there was little consistency between \u2018magnocellular deficit\u2019 groups comprising individuals with the lowest sensitivity for each task. Our results suggest that different \u2018magnocellular tasks\u2019 reflect different sources of variance, and thus are not general measures of \u2018magnocellular function\u2019.\n          <\/jats:p>","DOI":"10.1098\/rspb.2012.1430","type":"journal-article","created":{"date-parts":[[2012,8,15]],"date-time":"2012-08-15T09:19:44Z","timestamp":1345022384000},"page":"4263-4271","update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":36,"title":["Do different \u2018magnocellular tasks\u2019 probe the same neural substrate?"],"prefix":"10.1098","volume":"279","author":[{"given":"Patrick T.","family":"Goodbourn","sequence":"first","affiliation":[{"name":"Department of Experimental Psychology, University of Cambridge, Downing Street, Cambridge CB2 3EB, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jenny M.","family":"Bosten","sequence":"additional","affiliation":[{"name":"Department of Experimental Psychology, University of Cambridge, Downing Street, Cambridge CB2 3EB, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruth E.","family":"Hogg","sequence":"additional","affiliation":[{"name":"Department of Experimental Psychology, University of Cambridge, Downing Street, Cambridge CB2 3EB, UK"},{"name":"Centre for Vision and Vascular Science, Queen's University Belfast, Royal Victoria Hospital, Grosvenor Road, Belfast BT12 6BA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gary","family":"Bargary","sequence":"additional","affiliation":[{"name":"Department of Experimental Psychology, University of Cambridge, Downing Street, Cambridge CB2 3EB, UK"},{"name":"Department of Optometry and Visual Science, City University London, Northampton Square, London EC1V 0HB, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam J.","family":"Lawrance-Owen","sequence":"additional","affiliation":[{"name":"Department of Experimental Psychology, University of Cambridge, Downing Street, Cambridge CB2 3EB, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
