Premack’s conclusions on abilities needed to figure out what is same?
○ They must recognise that two independent objects were both blue and that this aspect makes them the same
○They must also recognise the sameness can be ‘immediately extrapolated and symbolically represented not only for two other blue items but for two novel, independent green items. These have nothing in common with the first item
