There was a study I particularly liked in which a group of depressed and a group of non-depressed people were asked to play a video game for an hour, and at the end of the hour, they were asked how many little monsters they thought they had killed.
Había un estudo que  me gustaba especialmente no cal a un grupo de xente deprimida e a un de xente non deprimida se lles pide que xoguen  a un videoxogo durante unha hora, e ao final desa hora, preguntábaselles cantos monstruíños pensaban que mataran.
