Abstract：
:We measured increment thresholds up to 5 degrees eccentricity using a 10' dia flash viewed against 10(4) td of 572-nm background. We found two distinct sensitivity profiles, one with flash wavelengths 410-470 nm and another with 520-580 nm. Spectral sensitivity plots indicate blue-sensitive cones and green-sensitive cones for the two profiles, respectively. Sensitivity of blue-sensitive cones is maximum at 1 degree eccentricity. Measurements at greater eccentricities are susceptible to adaptation to test field. The light-collecting area of blue-sensitive cones raised to a power follows the sensitivity profile of blue-sensitive cones.

VISION RESEARCH文献大全abstract：:Recent research has shown that reading disabled children find it unusually difficult to detect flickering or moving visual stimuli, consistent with impaired processing in the magnocellular visual stream. Yet, it remains controversial to suggest that reduced visual sensitivity of this kind might affect children's readi...
