"The Power of Kawaii", a recent paper published by Japanese researchers shows higher levels of concentration after viewing pictures which are cute- for instance pictures of babies, or kittens.
During a study, subjects were asked to perform jobs before and after looking at seven pictures of various puppies and kittens. Some subjects were also shown images of food to compare the responses. The group which viewed cute pictures experienced an increase in performance by 44%. They were also able to finish the task faster by 12%.
The study revealed that when people viewed cute pictures they felt positive and this perhaps motivated them to complete the task at hand.
