Was a quasi-experiment as the IV of weather the participant was a high or low delayer was naturally occurring, and so cannot be directly manipulated by the experimenter.
The DV was the performance on the impulse control cognitive go/no-go task in both experiments, Experiment 2 was the imaging results using an fMRI
