Document Summary
Basic understanding of numbers, cross-culturally, around age 5. All cultures have way of adding, subtracting, comparing and discussing numbers. 1st week of life can discriminate between sets of 1 - 3 objects. 5 months can discriminate the difference between small sets of 1 - 3 objects. 6 months can represent numbers abstractly and across modalities (sight, sound, touch) If you play 2 drum beats, infants will look at the screen with 2 objects. 6 months: approximate sense of larger numbers (<20) Amount wrong is proportional to what is seen. Researchers disagree about whether very young infants have true representations of #s. Teach them to pick the side that has more. Touch screen: trained to touch the side of the screen with the greater number of dots. 5 months old are able to do arithmetic. Adding and subtracting, not perceptual similarity is driving their expectations.
