Temperament is innate but hackable, animal studies suggest
Emotional reactivity and vulnerability to stress are largely inherited in rodents — but can be modified in early life by targeting inflammation-related cells or even just adjusting an animal’s environment.

Autism research hits the road
Some scientists are thinking creatively about how to collect data in flexible environments and meet communities where they’re at.

Amygdala-linked brain areas grow differently in autism
The growth differences vary between autistic boys and girls and are most apparent among children with prominent social difficulties.

Null and Noteworthy: Halted vasopressin trial, intact visual memory, a new way to study emotions
In this edition of Null and Noteworthy, a large clinical trial goes sideways, while memory and emotions hold up.

How an understudied trait has skewed autism studies for decades
Many autistic people have a little-known trait called alexithymia, defined as having difficulty identifying one's own emotions. New research suggests that the overlap has been confounding studies of emotional issues in people with autism for decades.

Inflexible thinking in adolescence linked to emotional, behavioral issues in adulthood
Treating cognitive inflexibility — for example, by practicing problem-solving — might help ease anxiety and depression in autistic people.

Alexithymia, not autism, may drive eye-gaze patterns
How autistic people look at a face may be linked more to alexithymia, a condition marked by difficulties recognizing one's own emotions, than to autism.

The benefits of special interests in autism
Researchers are studying how the intense passions of autistic people shape the brain, improve well-being and enhance learning.

Emotional challenges predict hospital stays in autistic children
Autistic children who have difficulty managing their emotions are also likely to take medication and need assistance from emergency responders.
