Hello!

Hope you all are off to a great start this morning.

Just a reminder, here are the thought questions from last nights assigned reading:

1. What kinds of techniques do Posner and his colleagues use to localize cognitive functions?
2. How is PET scanning used to study cognitive processes? What kinds of assumptions does PET scanning make?
3. What is the reason for subtracting activations recorded in a control state from those recorded during presentation of a target stimulus?
4. What is the joint approach that Posner believes to be the key to understanding many cognitive disorders?
5. To what extent should researchers generalize the results of studies of patients with brain lesions to people in general? Support your position.

Also, here is a color version of Figure 4:

(From Posner et al., (1998).  Localization of Cognitive Operations in the Human Brain, Science, 240(4859), 1627-1631.)  PMID: 3289116

See you tomorrow evening!
