Temporal Integration and Attention: Contributions of Visible Persistence and Masking
The perception of moving objects and scenes illuminated by lightning are influenced by the inherent sluggishness of our visual system. This phenomenon, called visible persistence, has been considered a hard-wired aspect of human vision. As such, it has been assumed that its duration was independent of higher level goals. This assumption was tested in this thesis by experiments in which attentio...
متن کاملContinuous measurement of visible persistence.
In the synchrony judgment paradigm, observers judge whether a click precedes or follows the onset of a light flash and, on other trials, whether or not a click precedes light termination. The interclick interval defines the duration of visible persistence. An elaboration of this method consists of two phases: In Phase 1, the luminance of a reference stimulus is psychophysically matched to the p...

مطالعه حاضر تلاشی است برای بررسی تأثیرات به کارگیری فرهنگ لغات ، یکی از مهمترین ابزارهای یادگیری واژگان درفراگیری زبان خارجی، بر روی دانش لغوی. دراین تحقیق فرهنگ های الکترونیکی در قیاس با فرهنگ های چاپی مورد بررسی قرارگرفته اند که آیا این فرهنگ ها تاثیرقابل توجهی بر روی دوبعد کمی و کیفی دانش لغوی یعنی عمق و گستره لغات می گذارند. همچنین مشخص گردیده است که آیا تفاوت قابل ملاحظه ای میان عمق و گستر...
15 صفحه اولSuppression of visible persistence in apparent motion.
Moving stimuli produce less smear than would be expected on the basis of visible persistence lasting 100-150 msec. Two experiments examined the duration of smear as a function of background luminance, target velocity, and duration ofthe display. It was found that smear decreased as background luminance increased, smear increased with velocity, and, as display duration increased from 10 to 160 m...
متن کاملThe visible persistence of stimuli in stroboscopic motion.
This paper reports an improved paradigm to measure visible persistence. The stimulus is a pair of lines stroboscopically displayed in successive positions moving in opposite directions. The subjects' judgement of simultaneous appearance of all the presented lines is used to estimate visible persistence. This paradigm permitted independent manipulation of spatial and temporal stimulus separation...
