Delinquency and Stimulation Seeking: Re-Analysis of Petrie's Study of Kinesthetic Aftereffects

Abstract
Individual differences in kinesthetic aftereffects presumably reflect differential modulation of stimulus intensity. Supporting this view, Petrie (1962) found that delinquents showed greater reduction, i.e., smaller size judgments after inducing stimulation, than nondelinquents. Recent evidence has contraindicated use of Petrie's two-session procedure. Here, using only Petrie's data from Session 1 and a more appropriately defined control group, the original findings were reconfirmed.
