The subtraction technique for fMRI involves what procedure? 2. A double dissociation has been observed in brain injuries that affect semantic and episodic memories. What does this mean? a) Patients have been found who have impairment to both semantic and episodic memory. b) Brain injuries always impair both forms of memory, or neither forms of memory. c) Î Patients have been found who have impairment to semantic memory but not to episodic memory, and other patients have been found who have impairment to episodic memory but not to semantic memory. d) fMRI reveals that brain injuries that affect semantic memory are in different parts of the brain from brain injuries that affect episodic memory. [Technically, this answer is not correct because a double dissociation can be found as in (c) without having evidence that the brain injuries are in different parts of the brain. Nevertheless (d) strongly suggests that (c) is true, so we are counting (d) as correct as well as (c).]

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
