Right Dorsolateral Prefrontal Cortex Activation during a Time Production Task: A Functional Near-Infrared Spectroscopy Study

Figure 2

Schematic representation of the two sets of instruction sequences (Patterns A and B) that comprised the estimation of time duration test. All participants were assigned to one of two groups. Each group was then assigned to one of two patterns to balance the two conditions. Each condition was repeated three times in a predetermined pattern; thus, the experiments consisted of six blocks, with a 60 s break between blocks. The time production task consisted of marking the start and end of perceived times of specified intervals by pressing a button on the response box. The intervals (3, 6, 9, 12, or 15 s) were randomized for each participant. The button-pressing task was a control task.
