There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

But only under the right lighting conditions, adds the authors of the study, both from the School of Psychology: professor Randall Engle and graduate student Jason Tsukahara. They gave reasoning, memory, and attention tests to volunteers and found that as well as being linked to arousal and exhaustion, pupil dilation can be used to understand the individual differences in intelligence, discovering that the larger the pupils, the higher the intelligence — except in the brightest lighting conditions. The study says this could be due to people with larger pupils having better results regulation of brain activity in a region linked to intelligence and memory. (Coverage of this study also appears in MSN Australia.)
