About
This study is designed to test whether computer-based cognitive exercises are helpful for reducing a specific type of impulsivity. Also, the study is testing whether these are exercises are associated with specific changes in behavior and in the brain. Participants will be psychiatric patients enrolled in a partial hospitalization program. Half of these participants will receive usual treatment, and half will complete computer-based cognitive exercises in addition to usual treatment.
Full description
Impulsivity has different components. One personality trait related to impulsivity, known as "urgency," is strongly related to many different mental health symptoms and risky behaviors. Urgency refers to impulsivity specifically in the context of strong emotions.
Research shows that higher levels of urgency are related to specific deficits in cognition. Problems with response inhibition--the ability to cancel or withhold a planned action--are associated with urgency. Also, research shows that difficulties in another aspect of cognition--working memory--may moderate the relationship between inhibition deficits and urgency. One previous study found that people who practiced computerized response inhibition and working memory tasks for two weeks reported significant decreases in urgency.
It is unknown if these computerized tasks would be helpful for reducing urgency in adults with psychiatric disorders. Furthermore, it is unknown if changes in urgency are related to changes in the brain mechanisms that help to support response inhibition. This study will collect data on brain activity while people are completing response inhibition tasks.
