A Look Tells All: Scientific American - 0 views
Ekman, however, was fascinated by the mystery of nonverbal communication. He wanted to understand why some people had little trouble decoding the feelings of others, almost as if they were reading an open book, whereas others fell for one con artist after another. His motto was: trust your eyes, not conventional wisdom. The widespread belief then was that facial expressions arose simply from cultural learning: a child in a given culture learned the faces that accompanied particular emotions by observing people, and over time different cultures developed different expressions. Even renowned researchers such as anthropologist Margaret Mead were unconvinced of the existence of a universal repertoire of expressions, as Charles Darwin had proposed in his book The Expression of the Emotions in Man and Animals, published in 1872 but subsequently ignored.
More Evidence That Intelligence Is Largely Inherited: Researchers Find That Genes Deter... - 0 views
In a study published recently in the Journal of Neuroscience, UCLA neurology professor Paul Thompson and colleagues used a new type of brain-imaging scanner to show that intelligence is strongly influenced by the quality of the brain's axons, or wiring that sends signals throughout the brain. The faster the signaling, the faster the brain processes information. And since the integrity of the brain's wiring is influenced by genes, the genes we inherit play a far greater role in intelligence than was previously thought.
