  1. Underlying Neural Mechanisms of the Triple-Code Model Tariqa Ackbarali Barry University Dehaene, S., M. Piazza, P. Pinel, and L. Cohen. 2003. Three parietal circuits for number processing. Cognitive Neuropsychology, 20: 487-506.

  2. Introduction • Cognitive and Neuro-anatomical model of number processing. Schematic Diagram of the architecture of the triple-code model (Dehaene & Cohen, 1995).

  3. Proposition of Triple-Code Model Triple Code Model Analog Magnitude Code Visual Arabic Code Auditory Verbal Code Direct Asemantic Route Indirect Semantic Route

  4. Three Codes • Analog Magnitude code: • Semantic knowledge of numbers • Bilateral inferior parietal area • Visual Arabic code: • Multi-digit operations and parity judgements • Bilateral Ventral Occipito-Temporal Area • Auditory Verbal code: • Rote verbal memory • Left-Hemispheric Perisylvian area

  5. Code 1: Analog Magnitude Code • Magnitude Comparison • Proximity • Simple quantity manipulations • Bi-lateral inferior parietal cortices.

  6. Code 2: Visual Arabic Code • Multi-digit operations • Parity Judgements • Bi-lateral inferior ventral occipito-temporal areas

  7. Code 3: Auditory Verbal Code • Rote arithmetic facts • Perisylvian network of dominant hemisphere

  8. Routes • Direct Asemantic Route: • Visual Identification • Visuo-verbal transcoding • Verbal sequence completion • Indirect Semantic Route • Semantically meaningful manipulations • Transmittal of resulting quantity • Naming

  9. Research Question • This study will investigate the triple-code model by examining the relationship between performance on standard neuropsychological tests and performance on algebra problems.
