antipower \$m[1]:Before you contact with faculty members, I strongly suggest that you read some of the faculty member's recent paper. You can show your research interests and ideas. If faculty members do not respond to your emails (Big names usually don't), perhaps contacting the current Ph.D students is a good idea. Maybe you can plan to meet the Ph.D. office staff and current Ph.D. students first and ask them to refer some faculty members for you.
Thank you! I am studying famous consumer psychology paper currently. On the other side, I check school website to see professors' study interests. You provide a good way for me to approach those Big names. I will try.
