A degraded stimulus version of a continuous performance task CPT which required participants to detect target signals for 32 minutes, a task which had been shown to make the frontal lobes work especially hard, together with the right temporal and parietal lobes, so investigators could see how the different areas functioned.

This reduced activity in the prefrontal areas may explain impulsive behaviour, a loss of self-control, evidence of immaturity, altered emotionality and the inability to modify behaviour.

The dependent variable was whether the participant showed evidence of brain dysfunction in their prefrontal cortex and other areas such as the angular gyrus, amygdala, hippocampus, thalamus and corpus callosum.
