Two cohorts of monkeys chronically exposed to lead during the first year after birth and their controls were tested during adulthood for choice accuracy on a learning and memory task, delayed spatial alternation (DSA).
Finally, after the presentation of an interference task, delayed recall was included (seventh trial).
PFC cognitive function was measured by the spatial working memory task delayed alternation.
One hour after ingesting the capsule on each session, participants completed mood questionnaires and five impulsivity tasks: go/no-go task, delay discounting task, time estimation task, stop task, and the balloon analogue risk task (BART).
The experiment consisted of 6 runs in which 3 tasks (delay, dual and multi-tasking, described hereafter) were administered in pseudo-random order (28 trials by task, inter-stimuli interval = 3 s).
From 70 min to approximately 120 min after ingesting the capsules, subjects completed five impulsivity tasks: delay and probability discounting task, balloon analogue risk task (BART), go/no-go task, stop task, and simple reaction time test.
Proactively streamline your workload (at work and at home) by applying the four D's: Delete (discard tasks), Delay (reschedule for a more appropriate time), Diminish (create a shortcut) and Delegate (give to someone who can do it better, faster or at least good enough).
2) Behavioral tasks: Delay of Gratification and Delay discounting.
There's a phenomenon known as the Psychological Refractory Period, which occurs when two tasks are performed at the same time and the reaction time to one of the tasks is delayed because of the presence of the other task.
Sometimes household tasks get delayed because communication and affection are more important.
