Not-so-smart perception
Researchers studying associations between IQ and selected visual tasks (“Less is more for smart perception,” SN: 6/29/13, p. 18) report that tracking small moving foreground objects, a task at which high-IQ subjects excelled, is often more important than detecting large-object motion or attending to background activity. They suggest that for driving or walking in busy areas, high-IQers have an advantage over people with lower IQs, who are better at monitoring large objects.
