J Pak Psych Soc Jan ;11(2):16-8.

Objective: Specific purpose of present study was to investigate any possible cross cultural differences on acuity of approximate number system (ANS). Design: Place and duration: The study was conducted in Pakistan and America in duration of two and a half years. 144 American children were tested in Harvard lab for developmental studies in first one and a half year of the study; while 120 Pakistani children were tested in Government schools of Islamabad in last in one year of the study. Subject and Methods: Sample consisted of 264 first grade children from America (N =144) and Pakistan (N= 120). Panamath task was used in order to measure children’s numerical acuity. Results: Results revealed that there was no significant difference between two populations on numerical acuity thus suggesting that children from both cultures have equally promising cognitive capacity for numbers to learn mathematics and excel in it. Conclusion: Results have important implications for delayed mathematics learning and assessment of mathematic learning disabilities.
