Well, thats pretty vague. Workshops in what area?
Professional conferences offer tons of talks and workshops at their annual events, so try to attend one or 2 conferences a year. If you belong to APA or other professional organizations, you sometimes receive emails about Continuing education workshops or embedded online presentations. Also, join professional orgs and google things/topics that interest you. There is tons of streaming video presentations online these days. I was on Pearson's website reading about the MMPI's new RC scales and saw that they were offerig a workshop near me soon. 100 bucks, I doubt Ill go. However, our department constantly sends us emails about talks and presentations given at the med center, by practitioners in our area and faculty at nearby universities, or anything that is going on nearby. Too many emails actually. My lab is in actually at the psychiatry department, so I also try to attend grand rounds talks (neuro and psych) when I can. I will say, I find hearing the grand rounds talks by various distinguished faculty infinitely more interesting and educational than some of the "workshops" I've been to.
