Simple Reason Helps Males Evolve More Quickly

ScienceDaily (Nov. 16, 2007) — The observation that males evolve more quickly than females has been around since 19th century biologist Charles Darwin noted the majesty of a peacock's tail feather in comparison with the plainness of the peahen's.


No matter the species, males apparently ramp up flashier features and more melodious warbles in an eternal competition to win the best mates, a concept known as sexual selection.

Why males are in evolutionary overdrive even though they have essentially the same genes as females has been a mystery, but an explanation by University of Florida Genetics Institute researchers to appear online in the Proceedings of the National Academy of Sciences this week may shed light on the subject.

"It's because males are simpler," said Marta Wayne, an associate professor of zoology in the College of Liberal Arts and Sciences and director of UF's Graduate Program in Genetics and Genomics. "The mode of inheritance in males involves simpler genetic architecture that does not include as many interactions between genes as could be involved in female inheritance.”

Tracking Your Team
Colors Are Key To Keeping Your Eyes On The Game

December 1, 2006 — People can focus on more than three items at a time if those items share a common color. Psychologists at Johns Hopkins University have demonstrated that when players wear uniforms, it allows spectators, players and coaches at major sporting events to overcome humans' natural limit of tracking no more than three objects at a time. The common color of uniforms allows them to overcome the usual limit because they perceive separate individuals as a single set.

Color helps the fans, refs and coaches stay focused on an action-packed game. But what if everyone was wearing the same color? Could you still pay attention to the game?

If it weren't for colored jerseys, the game could be hard to follow. Johns Hopkins University Psychologist Justin Halberda, Ph.D., says our brains have trouble keeping track of more than three objects -- or players -- at one time.

"It appears to be something fundamental about the way the brain is made, that attention is linked to three objects at once," Dr. Halberda tells Ivanhoe.

A new study at Johns Hopkins shows color is the key to grabbing your attention. When multiple players are in one color, the brain can keep track of several at once. Volunteers viewing a series of flashing colored dots could accurately count large numbers of dots of the same color.

"It appears to be something fundamental about the way the brain is made, that attention is linked to three objects at once," Dr. Halberda tells Ivanhoe.

“OK, thesis, antithesis synthesis and the rule of three on one. Hut.”

In Children And Adolescents, Low Self-esteem Increases Materialism

ScienceDaily (Nov. 16, 2007) — One of the first studies to focus on materialism among children and its development reveals a strong connection between an increase in materialism during adolescence and a decline in self-esteem.

Indeed, Lan Nguyen Chaplin (University of Illinois Urbana-Champaign) and Deborah Roedder John (University of Minnesota) show that the relationship appears to more than just a correlation, but a causal relationship -- low self esteem causes increased materialism and raising self esteem decreases materialism.

In a forthcoming study in the Journal of Consumer Research, Chaplin and John studied children of different age groups and found that, generally, self-esteem increases from middle childhood (8-9 years) to early adolescence (12-13 years), but then declines during adolescence until the end of high school (16-18 years). This mirrors patterns in materialism, which increases in early adolescence but decreases in late adolescence during the transition into young adulthood.

They found that even a simple gesture to raise self esteem dramatically decreased materialism, which provides a way to cope with insecurity: "By the time children reach early adolescence, and experience a decline in self-esteem, the stage is set for the use of material possessions as a coping strategy for feelings of low self-worth," they write.

How about that Marx guy, does he know about this?
