Giurfa et al.(2001) - continue Result: Bees have the concept of same and difference!
Paradigm: Training and transfer test Method: use two paddles to represent same or difference Mercado III et al. (2000) - continue

Symmetry interpretation is not always controlled for. • Symmetry applies to the overall visual pattern. • ‘Same’ is a relation between two objects. • Usually no different results between ‘Same’ and ‘Different’. General problems of this literature
Is the concept of difference harder or impossible for infants to learn? Questions
1. Mental representation of stimulus 2. Association between a side of screen and each representation What are the two requirements?
Hold 1strequirement constant Test whether14 month-oldcan associate a side to each representation Current Study - Stage 1
Determine at what age infants can associate each side with a representation Goal of Stage 1
1. Mental representation of stimulus 2. Association between a side on screen and each representation What are the two requirements?
Hold 2ndrequirement constant Test infants’ ability to represent structure AA and AB (same vs. difference) Current Study - Stage 2
Successful: associate AA to one side while AB to another • Infants have concept of same and difference • Unsuccessful: only associate AA to one side but not AB to another • Infants might only have the concept of same • Concept of difference might be more difficult Predicted Result
