What Prototypes Can Teach Us About Unknown Knowledge

New Paradigm: • Prototype Priming, i.e. RTs are measured. Learn set: • Stimuli grouped with the target according to their similarity with the prototype. • Overall 1400 presentations of stimulus samples, i.e. 700 RTs. Test set: • New stimuli. • One half grouped analogously to learn set (Sti1), the other half inversely (Sti2). • 100 presentations overall, i.e. 2x25 RTs. Control group: • No grouping in the learn set, no prototype priming possible
