Features of the environment matter too: In one experiment, volunteers with a cold rod placed on  the back of their hand reported feeling more pain when they were  shown a red light than a blue one, even though the rod was the same  temperature each time.
Značajke okoline također su važne. U jednom ekperimentu volonterima kojima je prislonjen ledeni štap na stražnju stranu ruke izjavili su kako osjećaju jaču bol kada im je pokazano crveno svjetlo nego plavo, iako je štap svaki puta bio iste temperature.
