have demonstrated that the perception of cold temperatures elicits greater
cognitive control, even from a photo.
"Metaphorical phrases like
"coldly calculating," "heated response," and
"cool-headed" actually have some scientific validity which we
demonstrate in our study," says lead researcher Dr. Idit Shalev of BGU’s
Department of Education. "Previous research has focused on the actual
effect of temperature on the psychological phenomenon known as 'cognitive
control,' but this is the first time we were able to measure the effects of
perceived temperature." The study, "Keep it Cool: Temperature Priming Effect on Cognitive Control Research" was published in Psychological Research.
Cognitive control is the process by which goals or
plans influence behavior and involves the ability to deliberately inhibit
responses to maximize the long-term best interests of the individual.
Along with Dr. Shalev the other researchers were Prof.Nachshon Meiran of BGU’s Department of Psychology and their student Eliran Halali, now a faculty member at Bar-Ilan University’s Department of Psychology.
The researchers conducted two experiments in the
study. In the first, 87 students
performed an "anti-saccade task" which requires looking in the
opposite direction of a moving object and measures cognitive control. In the
second experiment, 28 female students were asked to perform the same anti-saccade
task, but this time were asked to physically imagine themselves in a picture of
winter scenery, a temperature neutral concrete street or a sunny landscape
depicted as the background image in the test.

“The results indicated that those viewing the
cold landscape did better and that even without a physical trigger, cognitive
control can be activated through conceptual processes alone," says Shalev.
The researchers also examine the possibility that there
is a common explanation for the relation of temperature and cognitive control
with social proximity. "While warmth signaling promotes a relaxed
attitude, cool signals alertness and possible need for greater cognitive
control," the study concludes.
