Recovering the motion of objects \nby integrating the motion of their components is a difficult \nvisual task. Successful integration produces coherent global \nobject motion, while a failure to integrate leaves the \nincoherent local motions of the components unlinked. We \ncompared the ability of perception and pursuit to perform \nmotion integration by measuring direction judgments and \nthe concomitant eye-movement responses to line-figure parallelograms \nmoving behind stationary rectangular apertures. The apertures \nwere constructed such that only the line segments corresponding \nto the parallelogram's sides were visible; thus, recovering \nglobal motion required the integration of the local segment \nmotion. We investigated several potential motion-integration \nrules by using stimuli with different object, vector-average, \nand line-segment terminator-motion directions. We used \nan oculometric decision rule to directly compare direction \ndiscrimination for pursuit and perception. For visible \napertures, the percept was a coherent object, and both \nthe pursuit and perceptual performance were close to the \nobject-motion prediction. For invisible apertures, the \npercept was incoherently moving segments, and both the \npursuit and perceptual performance were close to the terminator-motion \nprediction. Furthermore, both psychometric and oculometric \ndirection thresholds were much higher for invisible apertures \nthan for visible apertures. We constructed a model in which \nboth perception and pursuit are driven by a shared motion-processing \nstage, with perception having an additional input from \nan independent static-processing stage. Model simulations \nwere consistent with our perceptual and oculomotor data. \nBased on these results, we propose the use of pursuit as \nan objective and continuous measure of perceptual coherence. \nOur results support the view that pursuit and perception \nshare a common motion-integration stage, perhaps within \nareas MT or MST.<\/jats:p>","DOI":"10.1017\/s0952523800171147","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T13:39:16Z","timestamp":1027777156000},"page":"139-153","source":"Crossref","is-referenced-by-count":55,"title":["Motion coherence affects human perception and pursuit similarly"],"prefix":"10.48130","volume":"17","author":[{"given":"BRENT R.","family":"BEUTTER","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"LELAND S.","family":"STONE","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"27968","published-online":{"date-parts":[[2000,1,1]]},"container-title":["Visual Neuroscience"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0952523800171147","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,1,2]],"date-time":"2025-01-02T20:00:16Z","timestamp":1735848016000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0952523800171147\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2000,1]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2000,1]]}},"alternative-id":["S0952523800171147"],"URL":"https:\/\/doi.org\/10.1017\/s0952523800171147","relation":{},"ISSN":["0952-5238","1469-8714"],"issn-type":[{"value":"0952-5238","type":"print"},{"value":"1469-8714","type":"electronic"}],"subject":[],"published":{"date-parts":[[2000,1]]}}}
