Reviews of professor Ron Keiflin

Rating: 4.0/5, difficulty: 3.0/5
Class was super interesting and I enjoyed the material but the lectures were super boring partly because it was a WF 9:30AM class. The midterm rocked a lot of people but the final was super reasonable. Wouldn't say it's an easy A but if you keep up with the material, you'll do just fine. 40% midterm 40% final 20% quizzes based on lecture material

Grade was based on one midterm (40%), one final (40%), and weekly quizzes (40%). The concepts for this course are complex but I found the exams and quizzes to be straight out the lecture which is nice. I would recommend taking him instead of other professors but def study the material and you should get an A. Quiz question repeated for exams! Easy!

Overall, decent at explaining concepts, but can occasionally be confusing. He does make a lot of effort to re-explain concepts you don't initially get and is friendly in office hours. Material is tricky, but he curved and gave EC to boost everyone's grades. Book isn't necessary, just study the lecture slides. One midterm and non-cumulative final.

Prof. Keiflin is one of my favorite professors I've had at UCSB. I had him during remote instruction and was pleasantly surprised by the high quality of teaching. The topics we covered were so interesting (addiction, motivation, model-based learning...). Loved every paper he assigned. Fair grader. He's so smart!

Class material is dry af but you get what you signed up for LOL. It's a hard class but if you go to his office hours he's pretty nice and walks you through concepts you don't understand.

The man is fine. His smooth french drawl never failed to lull me to sleep. What's ironic is that i took motivation (psy122) but for the life of me i could not find the motivation to stay awake. I swear i'm not even a simp. His voice is just deliciously sleep-inducing. Deepest sleep i had in years. Will be missed

really nice guy, explained the article really well. class consisted of a paper summary of an article, quizzes on weekly articles, and a group presentation. easy class, also clarified some stuff that was useful for other upper div psych classes

Okay, the lectures were SO boring. Can't blame him tho; The material just wasn't for me. I don't know how you can make conditioning into a ten-week class. Got repetitive. 
Regardless, he's a good professor and his exams are pretty straightforward. Weekly quizzes 20%, midterm 37.5%, final 37.5%, participation (forum posts) 5%. Definitely easy.
