ABSTRACT
As we note in Chapter 9, psychology comprises a number of different theoretical perspectives or approaches. Each approach makes different assumptions about the particular aspects of a person that are worthy of study, which helps to determine an underlying model or image of what people are like. In turn, this model or image determines a view of the nature of development, the preferred methods of study, the nature of psychological normality, the major cause(s) of abnormality, and the preferred methods and goals of treatment.
