On the other hand, if larger facilitation and interference effects are present in the RT than in the P3b latency, we can assume that effects originate after the peak latency of the P3b, in a late phase of task-execution.
Inability to deactivate the DM during the active phase of tasks has been generally related to poor performance during the active task condition (Raichle et al., 2001) and may thus be the explanation for its relation to poor IGT performance in the control cohort.
There was no effect of AP5 on object investigation levels in acquisition phase of either task, (treatment by task interaction F1,12 = 0.84, P > 0.1) or in the test phase F1,12 F1,12 = 4.67, P > 0.05; Table 1).
Thus, during a decision-making task, a peak was observed in adolescence (12 17 years) relative to childhood (8 10 years) and adulthood (19 26 years) for vmPFC activation during the choice phase and a peak in VS during the outcome phase of the task, despite comparable task performance [ 69].
However, no such novelty applies in the memory phase of our task as stimuli and task requirements are as for the learning phase.
Similarly, the lateral rostral PFC (together with the intraparietal sulcus) may specifically be implicated in exploratory phases of tasks involving rule finding (Daw et al. 2006).
The case of more engagement can be seen at the ending phase of the task as the participants showed gestures signaling they were satisfied with the task.
S2: (silence) (2) The case for task engagement can be seen as the participants provided their personal attitudes at the finishing phase of the task performance rather than at the beginning phase.
As initially estimated using a one sample t-test, 13 of 16 components were associated with task activity during the encoding stage and 10 of 16 components correlated with the recognition phase of the task.
Specifically, because we used a probe recognition type paradigm which is known to be somewhat easier than tasks with "free recall" demands, we expected that group differences in functional connectivity for the recognition phase of the task would be minimal.
