The Iowa Gambling Task (IGT) developed by Bechara et al. in 1994 is used to diagnose patients with Ventromedial Medial Prefrontal Cortex (VMPFC) lesions, and it has become a landmark in research on decision making. According to Bechara et al., the manipulation of progressive increments of monetary value can normalize the performance of patients with VMPFC lesions; thus, they developed a compute...

Kurzfassung. MITK-IGT ist eine Erweiterung des Medical Imaging Interaction Toolkits, die es ermöglicht Softwareprogramme im Bereich bildgestützte Therapie zu erstellen. Dieser Beitrag stellt die Architektur und Designprinzipien von MITK-IGT vor und vergleicht sie mit anderen Open Source Lösungen. Neben der Ansteuerung von Trackingsystemen und Visualisierungsmodulen liegt der Fokus von MITK-IGT ...

Our objective was to determine whether defects underlying impaired fasting glucose (IFG) are maintained and additive when combined with impaired glucose tolerance (IGT) (representing a progressive form of prediabetes) or are distinct in IFG/IGT (reflecting a parallel form of prediabetes). Volunteers with IFG (n = 10), IFG/IGT (n = 14), or normal glucose tolerance (NGT; n = 15) were matched for ...

OBJECTIVE Gestational diabetes mellitus (GDM), defined by two abnormal glucose values on a 3-h oral glucose tolerance test (OGTT), is associated with insulin resistance and a low serum concentration of adiponectin. The metabolic implications of impaired glucose tolerance (IGT) of pregnancy (i.e., a single abnormal value on an OGTT), however, are not well established. We sought to evaluate the m...

The Iowa Gambling Task (IGT) is a laboratory-based gambling paradigm which involves a conflict between immediate gain and delayed loss. In original IGT, the bad decks with lower expected values are associated with higher magnitude of reward and punishment, and the good decks with higher expected value are associated with lower magnitude of reward and punishment. Normal participants usually chos...

OBJECTIVE To 1). document the change in glucose tolerance for subjects with normal glucose tolerance (NGT) and impaired glucose tolerance (IGT) over time, 2). identify baseline factors associated with worsening of glucose tolerance, and 3). determine whether cardiovascular disease (CVD) risk factors associated with IGT improved in tandem with glucose tolerance. RESEARCH DESIGN Subjects with I...

The Iowa Gambling Task (IGT) simulates uncertain gains and losses in real life situations and thus is a good measure of uncertain decision-making. The role of working memory (WM) in IGT performance still remains unclear. The present study aimed to examine the effect of WM on IGT performance. Three groups of participants matched on gender ratio were randomly assigned to no WM load, low WM load, ...

This study aimed to develop a Japanese version of the Iowa Gambling Task (IGT) using Psychology Experiment Building Language based on English version. Additionally, we tested equivalence these versions biological test. We randomly assigned 63 undergraduate and graduate students from several universities our parallel design experiment. evaluated by determining differences between logs number car...

This study tested the hypotheses that older adults make less advantageous decisions than younger adults on the Iowa Gambling Task (IGT). Less advantageous decisions, as measured by the IGT, are characterized by choices that favor larger versus smaller immediate rewards, even though such choices may result in long-term negative consequences. The IGT and measures of neuropsychological function, p...
