 Firearms are Third Leading Cause of Death Among US Children

Firearm related deaths are the third leading cause of death overall among US children aged 1 to 17 years and the second leading cause of injury-related death. Previous studies examined selected outcomes or certain types of firearm injuries. [...] Nearly 1300 children die and 5790 are treated for gunshot wounds each year. Boys, older children, and minorities are disproportionately affected. Although unintentional firearm deaths among children declined from 2002 to 2014 and firearm homicides ...

 Why Kids Abandon Creative Play

The observation that play gets short shrift as children come of age in the Western world is surely as old and as perennial as that civilization itself. The Bible puts it thus: "When I was a child, I spake as a child, I felt as a child, I thought as a child: now that 1 am become a man, I have put away childish things." Turning their attention to the phenomenon, psychologists have asked what might be the causal factors. In the early 1900s, for instance, G. Stanley Hall argued that as children...

 How Brains Respond to Positive/Negative Feedback in Child...

In children up to eight or nine years old, the dopamine-modulating reward center in the nucleus accumbens reacts strongly to positive feedback (activating the prefrontal cortex) and minimally to negative feedback. In older children, increased activation still occurs in the PFC when dopamine is released in response to positive feedback (particularly in response to correct answers/ predictions). However, the greatest age-related change is the higher reactivity of the NAc to negative feedback an...

 How to Talk Math With Kids

Some simple ways to work numbers into the conversation: Note numbers on signs when you’re walking or driving with children: speed limits and exit numbers, building addresses, sale prices in store windows. Ask children to count how many toys they’re playing with, how many books they’ve pulled out to read, or how many pieces of food are on their plate. Use numbers when you refer to time, dates, and temperatures: how many hours and minutes until bedtime, how many weeks and days until a hol...

 Sound Localization

One trick our brains use to figure out the location of a sound is to compare the time it takes to reach each ear. For example, sound waves emanating from a wind chime located to your right will reach your right ear a few milliseconds earlier than they reach your left ear, and the brain uses this small timing difference to compute exactly how far to your right the chime is located. Researchers have capitalized on this timing difference to test sound localization, using a special experimental t...

 10,000 Injuries to Infants a Year from Cribs, Playpens, a...

An estimated 181 654 (95% confidence interval: 148 548–214 761) children younger than 2 years of age were treated in emergency departments in the United States for injuries related to cribs, playpens, and bassinets during the 19-year study period. There was an average of 9561 cases per year or an average of 12.1 injuries per 10 000 children younger than 2 years old per year. Most of the injuries involved cribs (83.2%), followed by playpens (12.6%) and bassinets (4.2%). The most common mecha...
