We measured colorimetric purity thresholds as a function of stimulus duration for seven wavelengths between 430 and 650 nm. Purity thresholds were measured in a hue substitution mode. The purity-duration function showed decreasing purity as duration was increased to about 640 msec. Functions for different wavelengths could be fit by a fixed chromatic template displaced on the purity axis. Incre...

Many moral codes place a special emphasis on bodily purity, and manipulations that directly target bodily purity have been shown to influence a variety of moral judgments. Across two studies, we demonstrated that reminders of physical purity influence specific moral judgments regarding behaviors in the sexual domain as well as broad political attitudes.
