Description:
During an infant monkey's first 28 postnatal weeks, the visual contrast sensitivity function develops its characteristic adult form. Contrast sensitivity is depressed relative to that of the adult for all spatial frequencies during the early postnatal weeks. Absolute sensitivity to frequencies below 5 cycles per degree approaches adult levels by 20 weeks after birth, whereas sensitivity to fine spatial detail continues to develop through 28 weeks. The results imply that the development of primate spatial vision is more complex than just an improvement in the ability to resolve acuity gratings.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boothe, R G -- Williams, R A -- Kiorpes, L -- Teller, D Y -- New York, N.Y. -- Science. 1980 Jun 13;208(4449):1290-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6769162" target="_blank"〉PubMed〈/a〉
