Example of the Go/Nogo Gamble block.
<p>Participants had to respond to gambling related pictures and try to withhold a response to neutral pictures.</p
Group interaction inhibition during gamble pictures.
<p>HCs showed more activation in the bilateral dorsolateral prefrontal cortex, right ventral lateral prefrontal cortex, and right anterior cingulate than PRGs. Results are depicted with a threshold of p<0.001 uncorrected. Colour bar represents corresponding T values.</p
Group interaction negative pictures – neutral pictures.
<p>PRGs showed more activation in the bilateral dorsolateral prefrontal cortex and right dorsal cingulate cortex than HCs. Results are depicted with a threshold of p<0.001 uncorrected to show the extent of the activation. Colour bar represents corresponding T values.</p
Group interaction during positive pictures.
<p>HCs showed more activation in the bilateral dorsolateral prefrontal cortex, and left ventral striatum than PRGs. Results are depicted with a threshold of p<0.001 uncorrected. Colour bar represents corresponding T values.</p
A: Reaction time during the different Go/NoGo blocks.
<p>HCs = Healthy controls, PRGs = problematic gamblers, msec = milliseconds; ** = significant group difference at p<0.05; * = trend for group differences <i>p</i><0.10; Error bars represent the standard errors of the mean. B: Percentage of impulsive errors during Go/NoGo blocks. HCs = Healthy controls, PRGs = Problematic gamblers, ** = significant group difference at p<0.05; * = trend for group differences <i>p</i><0.10; Error bars represent the standard deviations of the mean.</p
Group interaction positive pictures – neutral pictures.
<p>PRGs showed more activation in the left dorsolateral prefrontal cortex and left inferior frontal gyrus than HCs. Results are depicted with a threshold of p<0.001 uncorrected to show the extent of activation. Colour bar represents corresponding T values.</p
Group interaction gamble pictures – neutral pictures.
<p>PRGs showed more activation in the left dorsolateral prefrontal cortex, right ventral striatum, and right anterior cingulate, than HCs. Results are depicted with a threshold of p<0.001 uncorrected to show the extent of activation. Colour bar represents corresponding T values.</p
Group interaction neutral inhibition.
<p>PRGs showed more activation in the bilateral dorsolateral prefrontal cortex cortex, and right anterior cingulate than HCs. Results are depicted at a threshold of p<0.001 uncorrected. Colour bar represents the corresponding T values.</p
Schematic representation of the Stimulus Response Compatibility Task.
<p>The SRC consisted of two approach, avoid, and baseline blocks. Trials consisted of a cannabis or control image with a manikin left or right next to it. Approach-block instructions were to move the manikin towards cannabis images but away from other images. Avoid-block instructions were the reversed. The manikin could be moved left and right by pressing the corresponding left and right response box button. Baseline-block Instructions were to press left or right according to the manikin’s position.</p
Group interaction inhibition during negative pictures.
<p>HCs showed more activation than PRGs in the right dorsolateral prefrontal cortex, and left anterior cingulate. Results are depicted with a threshold of p<0.001 uncorrected. Colour bar represents corresponding T values.</p
