Posted: 14 Apr 2014 02:22 PM PDT

It's a hard pill to swallow, but if you're over 24 years of age you've already reached your peak in terms of your cognitive motor performance, according to a new study. In one of the first social science experiments to rest on big data, the researchers investigate when we start to experience an age-related decline in our cognitive motor skills and how we compensate for that.

Lower levels of blood sugar may make married people angrier at their spouses and even more likely to lash out aggressively, new research reveals. Researchers found that levels of blood glucose in married people, measured each night, predicted how angry they would be with their spouse that evening.

Dog ownership decisions in families of children with autism have been studied in a new project.

Babies prefer fairness -- but only if it benefits them -- in choosing a playmate

Posted: 14 Apr 2014 10:40 AM PDT

Babies as young as 15 months preferred people with the same ethnicity as themselves -- a phenomenon known as in-group bias, or favoring people who have the same characteristics as oneself. The findings show that 15-month-old babies value a person's fairness -- whether or not an experimenter equally distributes toys -- unless babies see that the experimenter unevenly distributed toys in a way that benefits a person of the same race as the infant.

This study is the first to identify when young fathers are at increased risk of developing depressive symptoms.

A study following more than 1,800 children from ages 6 months to nearly 8 years found a small but consistent association between increased television viewing and shorter sleep duration. The presence of a television in the room where a child sleeps also was associated with less sleep, particularly in minority children.

Women who gain too much or too little weight during pregnancy at risk for having an overweight child

Posted: 14 Apr 2014 06:21 AM PDT

Gaining both too much or too little weight during pregnancy appears to increase the risk of having an overweight or obese child, according to a study. In one of the largest studies to examine current Institute of Medicine recommendations regarding pregnancy weight gain in relation to childhood obesity, researchers reviewed the electronic health records of 4,145 racially diverse females who had completed a health survey between 2007 and 2009 and subsequently had a baby.

Teaching to optimize learning or control misbehavior? Scale of disruptive behavior in schools seriously underestimated

Posted: 14 Apr 2014 06:20 AM PDT

The true extent of poor pupil behavior in schools is seriously underestimated, according to an academic. The research raises the question of the extent to which there is a right to learn in classrooms. The researcher argues that behavior cannot be interpreted as satisfactory if some pupils are impeding the learning of others and if teachers are not able to teach the class in a way that focuses primarily on optimizing pupil learning rather than on control issues.
