I'll reword the phase "picked up" as "improved" in the following context Please kindly point it out if I am wrong.

But what's distinctive about this course is that in addition to the contributions that are made by the philosophical side of the equation, we're also going to be drawing from a number of other disciplines. So one of the main themes of the course will be to think about how the questions raised by the traditional philosophers that I've mentioned already are picked up in the contemporary cognitive science tradition.
