Measuring Delay Discounting in Humans Using an Adjusting Amount Task.
Delay discounting refers to a decline in the value of a reward when it is delayed relative to when it is immediately available. Delay discounting tasks are used to identify indifference points, which reflect equal preference for two dichotomous reward alternatives differing in both delay and magnitude. Indifference points are key to assessing the shape of a delay-discounting gradient because th...

متن کاملfMRI Reactivity to Trial Difficulty on a Delay Discounting Task Predicts Weight Gain in Obese Women
Obesity is a serious public health issue. Obesity may be accompanied by abnormalities in executive function circuitry related to impulsivity. A useful task for studying impulsivity is the delay discounting (DD) of money task, in which an individual chooses in a series of trials between an immediate and a delayed, but greater, amount of money. On the DD task, individuals with various addictions ...
متن کاملDo the adjusting-delay and increasing-delay tasks measure the same construct: delay discounting?
Delay discounting describes the subjective devaluation of a reward when it is delayed. In animals, the adjusting-delay (AD) and increasing-delay (ID) tasks often are used to assess individual differences in, and drug effects on, delay discounting. No study to date, however, has compared systematically the measures of discounting produced in these tasks. The current study examined the correlatio...
متن کاملB1 Mapping with whole brain coverage in less than one minute
Introduction There is great demand for fast B1 mapping techniques, e.g. for correction of magnetization transfer ratio maps [1] or of quantitative T1 maps [2]. Several methods have been proposed, such as the acquisition of a spin echo and a stimulated echo (STE) [3], the performance of two acquisitions with different excitation angles [4], or the interleaved acquisition of two FLASH images with...
