For most people, narcissism wanes as they age. A new study reports the magnitude of the decline of narcissistic traits is tied to specific career and personal relationship choices. However, this is not true for everyone. Some people remained just as narcissistic at the age of 41 as they were during their late teens. 3% of subjects showed increased narcissistic traits between the ages of 18 and 41.
A positive correlation has been identified between prosocial and rebellious behaviors in teens. The more risk taking behaviors a teen exhibited, the more likely they were to act prosocially. The findings suggest the same developmental processes are at work for both types of behaviors. Also noted was faster brain development in the medial prefrontal cortex predicted a decrease in rebellious behavior.
A new study reveals our longevity and sexual maturity are governed by our brains, not our bodies. Researchers discovered that animals with more neurons in the cerebral cortex live longer, regardless of their body size.
A new study reveals the youngest children in a class are more likely than their older peers to be diagnosed with ADHD. Researchers say the problem may lie with some teachers mistakenly believing a child's immaturity compared to older classmates is actually ADHD.
A new study explores how personality development and ego may be reflected in our everyday language. Researchers hope their findings will shed light on moral, social and cognitive development.
As different areas of the brain mature at different rates, neuroscientists argue it is more difficult that it seems to argue just when the brain 'reaches maturity'.
The process of neural connection re-organization begins earlier in girls. Researchers believe this may explain why they mature faster during teenage years.
