Document Summary

Introduction: there is very little research in this field, basic arithmetic and number processing skills are important in our society (associated with fewer incarceration rates, greater success in school and life) Evidence from the adult brain: dehaene & cohen (1995): 3 basic processing skills, 1. Associated with recognition of numbers (no semantic processing) Associated with the semantic processing of numbers. Bilateral horizontal segment of intraparietal suicus (hips: associated with numbers. Bilateral posterior superior parietal lobe (pspl: visual/spatial processing of numbers. Strategy variability evidence from brain imaging (grabner, ansari et al. , 2009: are different brain regions involved in procedural vs. retrieval strategies, 28 adults, during the scan they gave participants a set of arithmetic problems. Quantity processing: what is basic number processing (numerical magnitude processing), we have to be able to learn what basic numbers are, eg. 2 represents 2 objects, we use these systems on a daily basis. Reaction time and accuracy are dependent on the distance between two numbers.
