Petrie (1967) proposed a general theory of individual differences in style of Stimulus Intensity Modulation.The present article reviews and assesses research that has proceeded from Petrie's theorizing. Findings seem to support the concept of a central stimulus intensity control mechanism. Correlations among measures that purport to measure Stimulus Intensity Modulation are generally high in normal populations. Predictions made from Petrie's theory have met with moderate success. The final judgment on Petrie's theory however awaits the application of the newer methods of testing Stimulus Intensity Modulation to the critical areas for evaluating Petrie's theory. Suggestions for future research are provided.
