Answer to Question 1

Answer: The first piece of evidence that Eysenck drew on to support his view that personality differences were genetic and biological is consistent observation that his three factors of Psychoticism, Extraversion, and Neuroticism occur in cultures as diverse as African, Asian, European and North American. Second, there is evidence that once categorized, people stay consistent across time and situation. Responses and habits may change, but not the basic category into which they will fall in should they be re-tested. Third, all three categories show moderate heritability factors.

Answer to Question 2

Answer: The methods presented in the textbook for the study of brain structure include CT and MRI; for brain activity, cortical stimulation, EEG, EP, PET scan, fMRI and TMS. The student has considerable choice for answering this question. In general, the methods for looking at brain structure give you a sense of the shape, locations, density, etc., of brain tissue. Methods for looking at brain activity give you some sense of what is going on in the brain, where it is active at a given time, while some measure relative activity.
