Low-carb diets can affect dieters' cognition skills

MEDFORD/SOMERVILLE, Mass. -- A new study from the psychology department at Tufts University shows that when dieters eliminate carbohydrates from their meals, they performed more poorly on memory-based tasks than when they reduce calories, but maintain carbohydrates. When carbohydrates were reintro...

Scientist postulates 4 aspects of 'humaniqueness' differentiating human and animal cognition

CAMBRIDGE, Mass. Shedding new light on the great cognitive rift between humans and animals, a Harvard University scientist has synthesized four key differences in human and animal cognition into a hypothesis on what exactly differentiates human and animal thought. In new work presented for the...

Gene mutation linked to cognition is found only in humans

The human and chimpanzee genomes vary by just 1.2 percent, yet there is a considerable difference in the mental and linguistic capabilities between the two species.
