Example of a study in the CLOA that uses fMRI
Links to the Gabrieli article that we talked about in social and cultural factors affecting memory; the study used fMRI scanning.

Evaluating brain scanning in the CLOA
Useful to evaluate cognitive studies which use brain imaging; if they don’t control of motivation, conclusions may not be valid: also another example of a study using fMRI scans.

Examples of studies that have used virtual reality to assess participants cognitive abilities
A very interesting study as it looks at the cross over between emotion(affect), cognition and biology and uses virtual reality so ideal for IB! Performance on a Virtual Reality Spatial Memory Navigation Task in Depressed Patients — Gould et al_ 164 (3) 516 — Am J Psychiatry.mht
