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.
Gostei de um estudo, em que um grupo de deprimidos e um de não deprimidos tinham que jogar <i>videogame</i> por uma hora, e, ao final do tempo, respondiam quantos monstrinhos eles pensavam ter matado.
