You Smell Neurotic

1 Smell Someone's Personality

Body odor may help people figure out the personality traits of others, suggest researchers in Poland. According to MSNBC, the study is the first to test whether personality traits might be discerned from body scent. Participants or "judges" were asked to evaluate five personality traits of donors after smelling their shirts, which were placed in plastic bags. The ratings from the judges matched self-assessments of the shirt donors for three personality traits: dominance, neuroticism and extroversion. While the matches weren't perfect, the judges predicted the three personality traits as accurately as participants in a previous study predicted personality based on watching a video of the person. The study will be published in European Journal of Personality.

Four Genes in Same Family

2 Research Strengthens ADHD's Genetic Basis

A new study from the Children's Hospital of Philadelphia in which the genomes of 1,000 kids with attention-deficit/hyperactivity disorder (ADHD) and 4,100 controls found that 10 percent of those with the disorder had variations in four genes that play a role in the glutamate receptor (GMR). Glutamate is a neurotransmitter that helps neurons communicate with one another in the brain. The most significant results were seen in the GMR5 gene. This study confirms prior research that suggested the glutamate played a role in the disorder that makes it difficult for children to concentrate, sit still and control their impulses. Researchers are also hopeful that these results will allow them to design better and more individualized treatment for those with ADHD that have these variations.
