We're going to show babies a box of blue and yellow balls, and my then-graduate student, now colleague at Stanford, Hyowon Gweon, is going to pull three blue balls in a row out of this box, and when she pulls those balls out, she's going to squeeze them, and the balls are going to squeak.
Imos ensinarlles unha caixa  de bólas azuis e amarelas, e a que era a miña estudante graduada,  hoxe compañeira en Stanford, Hyowon Gweon, vai sacar tres bólas azuis  seguidas desta caixa, e despois de sacalas, vainas apertar, e as bólas van chiar.
