Brief summary

Understanding Daily Fluctuations in Self-Regulation, also known as the Digital Marshmallow Test (DMT), is a collaboration by Northwell Health, Cornell Tech, and Sage Bionetworks. Funded by the Robert Wood Johnson Foundation, this is a pioneering study to advance the science in identifying and helping individuals who act on short-term temptations, despite long-term consequences. Using Apple's ResearchKit(™) and Android's ResearchStack applications, the Digital Marshmallow Test will leverage the powerful capabilities of the smartphone to examine impulsivity using a range of game-like tasks and sensor capabilities within the mobile phone. Across studies, more impulsive individuals are significantly more likely to suffer from obesity, Type II Diabetes, substance abuse, gambling problems, suicidal behaviors, and increased criminality among many other problems. Early self-report studies reveal a relationship between the inability to delay gratification and different patterns of mobile phone use. This will be the first study to develop non-invasive mobile methods to identify and help those at greatest risk for impulsive responding before serious problems occur.
