In both cases, participants viewed the same face more than the old, if the photo of the man smiling and young, if it viragini face was something else.

After both experiments, participants were asked whether they agree with the statement that smiling faces look older, and in both cases the people just their actions confirming this idea, stated that they do not consider it a right. Scientists tend to explain this established stereotype that livaudais face, on the contrary, must look more young. Many people take this statement for granted and do not think that it may be wrong, but subconsciously continue to perceive smiling faces as more old.

Trying to explain the phenomenon, forcing to perceive neutral faces as young, scientists suggest that a smiling person appear wrinkles around the eyes that unconsciously perceived as a sign of “old age”.
