Cholinergic Modulation of Perceptual Learning (061518A)

We are currently looking for volunteers to participate in an experiment in the Silver Lab, part of the Helen Wills Neuroscience Institute and Berkeley Optometry. The purpose of this experiment is to examine the effects of learning on visual perception. Tasks involve viewing images and making judgments about them. In addition, we will administer the Alzheimer’s medication Donepezil to determine its effects on learning and visual perception.

The entire study consists of 17 sessions over the course of roughly one month: 1 screening, 2 introductory, 2 pre-training, 2 post-training, and 10 for training. Before each of the last 16 sessions, and for an additional 4 days (20 days total), you will take either a Donepezil pill or an inactive placebo pill. Compensation will be $15/hour, plus a $100 bonus for successfully completing all 17 sessions.

Eligibility: Subjects must be 18 – 80 years old, healthy, and have normal vision (natural or corrected). Subjects must not be pregnant, smoke tobacco, have asthma or other lung problems, a history of seizure or heart arrhythmia, or taking medications that affect central nervous system function.
