Filter by: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.
Tourette syndrome (TS) is characterized by the presence of multiple vocal and motor tics. Behavioral disorders associated with TS are common, particularly impulsivity, anti-sociality and socially inappropriate behavior. Specifically, cognitive impulsivity could be the source of these troubles. Its anatomical substrates is based on connections between frontal and striatal areas. Initially, a battery of behavioral tests measuring different types of impulsivity (motor, cognitive and decision) will be administered on three groups of subjects: TS: 80 patients (40 patients treated and 40 untreated) and 40 healthy volunteers. Then, investigators will study the fronto-striatal connections in the TS group of 80 patients (40 patients treated and 40 untreated) compared to 40 healthy volunteers using neuroimaging techniques (3T MRI). The techniques used will be functional connectivity study of "resting state" MRI (RS-fMRI) combined with a reconstruction of white matter fibers by diffusion tensor imaging (DTI). Behavioral performance will be correlated with the correlation imaging data to highlight the functional anatomical substrates of impulsivity in patients with TS. Finally, investigators will look specifically using functional MRI activation, the anatomical and functional substrates of the three types of impulsivity (motor, cognitive and decision-making). Through this study, investigators hope to elucidate the anatomical and functional bases of cognitive impulsivity in patients with TS and thus lay the basis for more targeted treatments.
The objective of this study is to determine the relations among food insecurity status, obesity, and impulsive food choice patterns and to test the extent to which a mindful eating strategy reduces impulsive choice for food. The central hypothesis is that food-insecure individuals will demonstrate more impulsive food choice patterns and demonstrate a greater likelihood of obesity than individuals who are food secure. Two specific aims are proposed: Specific aim #1: Determine the relation between food insecurity, obesity, and impulsive food choice patterns in women. The working hypothesis is that food-insecure individuals, especially those that are obese, will exhibit more impulsive food choice patterns than food-secure individuals. Specific aim #2: Determine the efficacy of an extended mindfulness-based eating strategy on impulsive choice patterns among food insecure women. The working hypothesis is that mindful eating will reduce impulsive food choice patterns relative to baseline and control conditions, and will persist to follow-up. The investigators expect mindful eating to reduce impulsive choice compared to control conditions, despite food security status.
This study will evaluate the relationship between psychopathology, disordered eating, and impulsivity (measured by clinical interview, self-report measures, and objective testing) on changes in weight and psychosocial status in the first two years after bariatric surgery. Participants will be 300 adults who plan to undergo bariatric surgery. Participants will complete four assessments over a two-year period, one at baseline (before surgery) and 6, 12, and 24 months after surgery. Each assessment will include computer tasks, surveys, clinical interview, urine test, waist circumference and height/weight measurement. The investigators will track how psychopathology, disordered eating, and impulsivity are related to changes in weight and psychosocial status following bariatric surgery.
This study aims to use resting-state and task based functional Magnetic Resonance Imaging (fMRI) as a tool to evaluate trait characteristics of impulsivity in subjects with borderline personality disorder.
The purpose of this study is to determine the effects of tolcapone on decision making and alcohol intake using a laboratory bar (on-site alcohol self-administration) in alcohol drinkers.
The study aims to examine a battery of behavioral and questionnaire measures in 4 disorders clinically associated with impulsivity and in health controls, to: 1) investigate if the different populations have a distinct behavioral profile, and 2) to investigate if there are specific measures that are reliable and sensitive measures of impulsivity across diagnoses.
Inhibition control deficits is a major risk factor in the transition to the act in suicidal patients. Neuroimaging studies have shown that this failure was associated with hypoactivity in the prefrontal cortex (PFC), a brain area involved in the control of impulsivity. It was recently shown that a noninvasive brain stimulation session applied on the PFC reduces transiently impulsivity in healthy volunteers. Noninvasive brain stimulation modulates the activity and connectivity of neural network connected to the stimulation site. The investigators assume that a repetition of noninvasive brain stimulation sessions on the PFC will allow a more intense and longer lasting effect on impulsivity and cognitive control in healthy volunteers compared to a single session and to placebo stimulation. The investigators assume that this behavioral change will be accompanied by a change in brain activity measured by resting EEG for the patients in the active group. A more intense and longer lasting effect is an essential step to transfer these results to patient populations. The main objective is to study the effect of bilateral stimulation of the PFC by transcranial random noise stimulation (tRNS) on the inhibition control measured by the cognitive motor inhibition capacity (Go NoGo test). The secondary objectives are to study the effect of tRNS on verbal inhibition (measured with the Hayling test); on anxiety (measured with the State-trait anxiety inventory (STAI)),on angry (measured with the State-trait anger expression inventory (STAXI)) on verbal and nonverbal inhibition (measured by the Stroop test), on impulsive behavior (measured by the Barrat impulsiveness scale (BIS 10)) and on the neuronal electrical activity measured by EEG.
This pilot project will evaluate yoga as an intervention to improve attention and reduce challenging behaviors such as hyperactivity and impulsivity, rated by parent and teachers, in preschool age children with or "at risk" for attention-deficit hyperactivity disorder (ADHD). "At Risk" for ADHD will be defined as four or more hyperactive/impulsive and/or inattentive symptoms on the ADHD Rating Scale IV-Preschool Version as rated by parents or teachers. Using a randomized wait-list controlled experimental design, the investigators will explore the efficacy of practicing yoga for 6 weeks on behavioral symptoms, attentional control using a computer based tasks of attention, and heart rate variability (HRV), which is a measure of self-regulatory capacity. The investigators hypothesize that practicing yoga for six weeks of will improve ADHD and other behavioral symptoms based on parent and teacher rating scales, which will correlate with improvements in scores on the computer based task of attention as well as with improvements in HRV.
The proposed study is a pilot prospective, parallel groups, randomized, double blind, sham training-controlled, 9-session (over 3 weeks) clinical trial of AABM in 32 male and female veterans entering treatment for AUD at the VA Medical Center at San Francisco, California, between ages 18-65. The study consists of screening, 3-week AABM training, Week-4 post-test, and Week-12 follow-up. Assessment of inhibitory control, alcohol approach bias and craving will be administered at baseline and Week-4. Immediately following screening, patients will be randomly assigned to receive 9 sessions of real or sham AABM training (16 subjects each) taking place over three weeks. Following the 3 weeks of training, patients will complete a Week-4 post-test which includes assessment of alcohol approach bias, inhibitory control, and craving and a Week-12 follow-up assessing drinking behavior.
