I took 100A & 120B with shams. She is a TERRIBLE lecturer. YES, she TRIES to explains things in the simplest way possible, BUT she spends 10 minutes in a roundabout way to make a single point. She makes something SO simple -- so convoluted. I hated going to lectures because I would get so bored. I think the topic sensation & perception is pretty interesting, but I HATED the lecturer. Anyways, the class itself is ok. Two exams (midterm + final), one "paper critique" - which is only like 2 or 3 pages long, and hw assignment (took about 5-10 mins to complete each one). Overall, not a very hard class.

Professor Shams is excellent. I took 120B with Kellman in Fall Q, and, well, I'm retaking it. Prof. Shams explains things is a very basic way so that it's much easier to understand these often very abstract concepts. She has an accent, which is only sometimes hard to understand, but I find that it forces me to pay better attention. She is very concerned and is absolutely willing to explain concepts during her office hours. She even held office hours up until the midterm was being taken to explain last minute questions.

The other giant difference between the two courses were the discussion sections and the paper assignment...

In Kellman's class, the paper was a high graduate level article that needed to be critiqued. I had such a hard time even understanding what the paper was about, let alone writing my own paper about it AND designing my own experiment for it. The sections were mandatory with quizzes every week.

Shams' paper was much more digestible, very straight forward, and overall a much more doable assignment - they explained exactly what they were looking for (ex. what's the IV and DV?). The sections were optional without quizzes.

After taking this course with her, I have a much higher level of interest in sensation and perception in general. So if you must take this course, DEFINITELY take it with Shams.
