Architectures for numerical cognition

摘要: Current theories of numerical cognition differ in assumptions about the componential architecture number processing and extent notation-specific processes. To investigate these issues, 64 adult subjects were tested on simple addition multiplication problems presented Arabic digit or English number-word format. Overall, response times error rates much higher with word format, but more importantly, presentation format interacted arithmetic operation problem size. Operation errors (2 + 4 = 8), operand-naming 8 operand-intrusion (9 × 6 36) each characterized by a different x interaction, analysis inter-trial priming showed selective interference from preceding trials as function These types format-specific retrieval operation-specific effects are problematic for models that hypothesize notation-independent memory processes arithmetic. Furthermore, analyses errors, other operand-priming effects, revealed strong interactions reading number-fact processes; typically posited to be functionally independent. The results suggest complex encoding incorporates notation-dependent activation facts, well interpenetration
