Abstract:
Non-invasive functional neuroimaging techniques enable researchers to study the
neurobiological substrates of psychological processes. The increasingly large body of
neuroimaging research has two fundamental purposes. The first is to identify the brain
regions that underlie a particular psychological process while the second seeks to identify
differential responses of these regions to various stimuli or task challenges. The latter
focus yields insights into both how the brain accommodates varying task demands and
how differences between individuals or between clinical and healthy comparison groups
might be explained by differences in neurobiological functioning. To achieve these goals,
it is essential that one be able to isolate the psychological process of interest and how best
to do so, with particular regard to experimental design, is the focus of this chapter. Part II
will describe issues particular to psychological experimental design, that is, experimental
control over the cognitive or emotional process of interest. Part III focuses on data
analysis with emphasis on optimizing and isolating the neuroimaging signal in the
activated brain regions. Part III also addresses a number of practical matters that confront
all researchers when designing their experiments.
