Abstract
The subject matter of psychology is humans and their experiences and actions. This subject matter differs from the subject matter of physical science by being more highly contextualized, uncertain, and morally saturated. As a consequence, psychological theory must concern itself with context and moral significance and with the formulation of principles rather than causal laws. The development of psychological theory can be assisted by programs of inquiry that emphasize conceptual clarification and moral consideration, in addition to empirical demonstration. Programs of inquiry in psychology also should place a high value on reasoned criticism derivative from a wider array of scholarly methods and traditions. In all of this, psychology should be guided first and foremost by the nature of its subject matter. 2012 APA, all rights reserved)
