HEALTHY SUBJECTS NEEDED FOR A PSYCHOPHARMACOLOGY STUDY:

UC Berkeley, in collaboration with UC San Francisco, is seeking healthy subjects for a study of medications that may influence decision-making processes. To be eligible, you must:

1. Be between 18-50 years old
2. Have no major health problems
3. Be able to read and speak English
4. Be able to undergo an MRI scan
5. Be a non-drinker or a light social drinker (for women: less than 7 drinks / week; for men, less than 8 drinks / week)
6. Have no significant medical or psychiatric illnesses (such as anxiety or panic disorders, bipolar disease, major depression, or schizophrenia)
7. Not currently be using any psychoactive medications
8. Be willing to provide a blood sample for gene testing

This is a study that involves up to four sessions, on separate days, to take place on the U.C. Berkeley or U.C. San Francisco campuses. On some sessions, you will be given a one-time dose of medication or placebo (sugar pill). As a participant, you will be paid $12/hour for every hour of behavioral testing, $20/hour for every hour of MRI testing, and a completion bonus of $100. We anticipate that subjects who complete the study will earn approximately $300.

To volunteer, please contact us at (510) 985-3972, or email berkeleyresearchcenter@gmail.com.

Healthy people age 20 and older are invited to participate in a study to investigate brain changes that occur in normal aging using psychological assessment and brain scans.

Study Details:
-When you call to volunteer for this study a research associate will ask you a series of questions to determine your eligibility. 
-You will be paid $75 for participation in this study.  The study will take approximately 3-4 hours to complete.
-You will come to the University of California, Berkeley, where you will have a brief medical interview.  Following this, you will take a series of tests designed to assess your thinking abilities. These tests use pencil and paper or computers and involve things such as solving puzzles and remembering lists of words.
-We will call you periodically to see if you are interested in participating in other studies in laboratories at UC Berkeley.

Exclusions:
-Subjects who are presently not in good health, who have had any history of neurological or psychiatric problems, or who cannot speak English proficiently should not volunteer for the study. 

If you are interested in participating in this study, please contact the Jagust Lab: 510-643-6609

Neural bases of 3D-depth perception

The Levi and Silver labs are looking for participants with normal or corrected to normal vision. We will measure your 3D-depth perception: 10% of participants lack 3D-depth perception. To measure it, you will look at clouds of dots moving in depth on a computer screen. We will scan your brain after the measure and issue 3D images of your brain to you.

Conditions of eligibility:

1) normal or corrected-to-normal vision
2) Age 18-62
3) No clear claustrophobia, metal in body, pregnancy, tattoo on face/neck, pacemaker
4) No neurological or psychiatric disorder, or neuro-active medication

Visits in Minor Hall: 1 visit for 1.5 hour compensated at $15 per hour (+ parking/BART - special rates)
Visits in Li Ka Shing Center: 2 visits of 2-3h each compensated at $15 per hour (+ parking/BART - special rates)

Expected total compensation: $82.50 to $112.50

Human subjects are needed for research experiments in the Banks’ Vision Science Laboratory. The purpose of this research is to investigate the behavior of the visual system and the influence of 3d display properties on it.

Task
You will be shown objects with different display properties and your task would be to indicate with keyboard presses which objects appear different from the others, or which stimuli are closer/further in depth, or you may be asked to identify letters or textures. Accommodative (focus) response to these targets may be recorded using either a commercially available autorefractor or a Shack-Hartmann wavefront sensor, an investigational device built in the Banks’ Vision Science Lab. An experimental session will last approximately 1-2 hours. You may participate in two experimental sessions and the total time commitment can be up to 4 hours.

Requirements
1. Age 18 or over.
2. Have normal or corrected-to-normal vision using contact lenses. Participant should be able to see clearly at 20 feet what should normally be seen at that distance (i.e., 20/20 vision). This will be confirmed with a visual acuity test.
3. Have had a comprehensive eye exam within past 2 years with no evidence of retinal degenerative disease (including Age-related Macular Degeneration and Retinitis Pigmentosa) or other significant ocular health complaints.

Compensation
You will be paid $15.00 per hour, prorated by the half hour, for your participation. Graduate students and postdoctoral scholars in the Vision Science program may participate for research experience but will not receive compensation over their stipend. Participation in this research is voluntary and will have no bearing on your standing or grades at the University of California.

If you are interested in participating, please contact Steven Cholewiak via email (steven.cholewiak@berkeley.edu).

We are seeking individuals who wish to take part in a study of shared attention, more specifically in how we are attend to a source of speech in an environment that contains a number of speakers. This study constitutes research. Listeners will sit in the middle of this simulated “party” and a
visual display will direct attention to the “primary source.” Using buttons, the subject will answer a string of questions taken from the various speakers. There will be a small financial reward for each correct answer and
encouragement for attending to the preferred place will be given by presenting the majority of questions from that location. To make it interesting, the direction of attention will be changed during the course of
listening. It is kind of fun.
Please contact Berkeley.EarLab@gmail.com if you wish to participate in this study.
