Q Methodology and Control Theory: II. General Considerations

Abstract

The principles of control theory are presented, and their connection to Q
methodology is described. The perceptual prerequisites of the Q-sorting
task are considered, and the perceptual levels of control theory are
related to the selection of Q statements and conditions of instruction,
and to the interpretation of factors. The conclusion is reached that
control theory has advantages over the quantum and interbehaviour
theories often associated with Q methodology.
