Appearances Really Count When Rising to the Top
Even in the most egalitarian of working environments, certain people seem to reliably move to a higher status than others. They seem more competent and committed. In essence, they appear to be natural leaders. But groups don’t always place the most valuable or competent person in charge. Rather, the people who appear to be the most valuable or competent at any given time tend to achieve higher rank, a recent study indicates.

New Research on Genetics and Intelligence
Read about the latest research on genetics and intelligence: Literacy and Numeracy Are More Heritable Than Intelligence in Primary School Yulia Kovas, Ivan Voronin, Andrey Kaydalov, Sergey B. Malykh, Philip S. Dale, and Robert Plomin Are literacy and numeracy less heritable than general cognitive ability? Monozygotic and dizygotic twins were assessed for literacy, numeracy, and general cognitive ability at ages 7, 9, and 12. Literacy and numeracy were found to be more heritable than general cognitive ability at ages 7 and 9 but not at age 12.

Blindsight in Children With Cerebral Lesions
Congenital or acquired damage to the visual processing areas of the brain is often associated with a loss of vision. Despite sustaining damage to these brain areas, some people retain an unconscious ability to respond to visual stimuli — and ability termed blindsight. Although these people are not consciously aware of visual stimuli, they are in many instances able to direct their eyes towards target items and to discriminate the orientation and direction of movement presented in their area of blindness. Studies examining blindsight have found that those who acquire damage early in life retain more visual ability than those who acquire brain damage in adolescence or adulthood.

Genes May Predispose Some People to Focus on the Negative
New research finds that a previously known gene variant may predispose individuals to perceive emotional events — especially negative ones — more vividly than others. The new findings are published in Psychological Science, a journal of the Association for Psychological Science. “This is the first study to find that this genetic variation can significantly affect how people see and experience the world,” says psychological scientist Rebecca Todd of the University of British Columbia.

Study Identifies Genetic Tie to Marital Satisfaction
Psychological researchers have found, for the first time, a link between a gene variant and marital satisfaction. “An enduring mystery is, what makes one spouse so attuned to the emotional climate in a marriage, and another so oblivious?,” said APS Past President Robert Levenson, a professor at University of California, Berkeley and lead author of the study. “With these new genetic findings, we now understand much more about what determines just how important emotions are for different people.” Specifically, researchers from UC Berkeley and Northwestern University found a link between relationship fulfillment and a gene variant, or “allele,” known as 5-HTTLPR.
