Researchers found that the brain region critical for face perception is also active when humans become expert in recognizing novel objects, contradicting the idea of separate brain mechanisms. The study used functional magnetic resonance imaging to test adults on identifying greebles, a class of complex three-dimensional objects.
Researchers identified education and current health status as significant predictors of improved or maintained cognitive performance in older African Americans. The study also found that women are less likely to experience decline in cognitive functioning than men.
A study by Purdue University professor Theodore Wachs found that children from highly noisy homes experience less cognitive growth, delayed language skills, and increased anxiety. To mitigate these effects, parents can implement suggestions such as turning off the TV, establishing quiet spaces, and imposing a regular schedule.
