Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Older adults demonstrate increased distractibility by task-irrelevant information which contributes to general cognitive impairment. However, it is yet unclear how changes in noradrenergic activity during aging influences attentional control. In the current study, tonic noradrenergic activity will be increased or decreased to investigate its behavioral and neural effects on attentional control.
