WSU researchers see gene influencing performance of sleep-deprived people
Washington State University researchers have discovered a genetic variation that predicts how well people perform certain mental tasks when they are sleep-deprived.
Their research shows that individuals with a particular variation of the DRD2 gene are resilient to the effects of sleep deprivation when completing tasks that require cognitive flexibility, the ability to make appropriate decisions based on changing information.
“Our work shows that there are people who are resilient to the effects of sleep deprivation when it comes to cognitive flexibility. Surprisingly these same people are just as affected as everyone else on other tasks that require different cognitive abilities, such as maintaining focus,” … » More …Read Story
Running marathons is hard—breaking up with your running group is harder
Leaving a group can mirror the experience of breaking up with a partner.
“Both involve brain regions that are also associated with physical pain,” says Dr. David Marcus, a faculty member of Washington State University’s psychology department. People experience a type of social pain when they are rejected or shunned by a group, similar to the pain experienced when a couple breaks up, whether it’s being kicked out of a high-school clique, or falling out with your family. This is compounded by the fact that a group can become part of a person’s self in much the same way as a romantic partner can, Marcus … » More …Read Story
Exploding Head Syndrome
The unusual name will certainly get your attention, but fortunately Exploding Head Syndrome is not life-threatening or physically harmful. In a recent study more than 10 percent of people experienced the syndrome, a sleep disorder in which crashing or exploding sounds make it difficult to fall and stay asleep.
Dr. Brian Sharpless, Assistant Professor of Psychology at Washington State University and author of Sleep Paralysis, explains that instead of the auditory neurons in the brain shutting down in the process of going to sleep, they all fire at once causing the loud noises.

Long-term cannabis use linked to muted stress response WSU study shows
A new study by Washington State University psychology researchers reveals a dampened physiological response to stress in chronic cannabis users.
Using a nationally recognized procedure designed to provoke elevated levels of stress, Carrie Cuttler, clinical assistant professor of psychology, Ryan McLaughlin, assistant professor of integrative physiology and neuroscience, and colleagues in the WSU Department of Psychology examined levels of the stress hormone cortisol in both chronic cannabis users and non-users.
“To the best of our knowledge, this is the first study to examine the effects of acute stress on salivary cortisol levels in chronic cannabis users compared to non-users,” Cuttler said.
