Interactions between color and luminance in the perception of orientation.
At the early stages of visual processing in humans and other primates, chromatic signals are carried to primary visual cortex (V1) via two chromatic channels and a third achromatic (luminance) channel. The sensitivities of the channels define the three cardinal axes of color space. A long-standing though controversial hypothesis is that the cortical pathways for color and form perception mainta...
متن کاملColour and luminance selectivity of spatial and temporal interactions in orientation perception
Previous studies have commented upon the similar phenomenology of simultaneous and successive interactions in the perception of orientation. These similarities have been taken as evidence of common mechanisms underlying the simultaneous tilt illusion (TI) and the successive tilt aftereffect (TAE). We measured the TI and TAE for four subjects for combinations of test and inducing stimuli modulat...
متن کاملthe comparative impact of prompts and recasts in processing instruction versus meaningful output-based instruction on efl learners’ writing accuracy
the purpose of the present study was to see which one of the two instruction-processing instruction (pi) and meaningful output based instruction (mobi) accompanied with prompt and recast- is more effective on efl learners’ writing accuracy. in order to homogenize the participants in term of language proficiency a preliminary english test (pet) was administrated between 74 intermediate students ...

15 صفحه اولFast long-range interactions in the early processing of luminance-defined form
Within a duration of 20 ms humans can compare the orientations of two test lines so as to encode and place in memory their mean orientation and orientation difference while ignoring noise lines in the space between the test lines. Furthermore, performance is not impaired by randomly varying the location of each test line from trial-to-trial. We conclude that the two test lines are not compared ...
