Document Summary
1, the system wants to track each individual object sensitive to differences in absolute number not ratios. Are they better at larger ratios compared to smaller ratios (approaching. 1:1): set of dots appeared, then went behind a screen, a new set of dots came up and went off screen, kids then asked if there were more red or blue dots. Infants rep(cid:396)ese(cid:374)t (cid:395)ua(cid:374)tit(cid:455): the(cid:455)"(cid:396)e se(cid:374)siti(cid:448)e to (cid:373)is(cid:373)at(cid:272)hes i(cid:374) (cid:374)u(cid:373)(cid:271)e(cid:396) In the hidden task, they need to maintain cardinality of the first set of objects in order to apply it to a second set of objects. I. e. you need a mental representation of the first set: it looks like numbers are really important for abstract operations that (cid:449)e (cid:272)a(cid:374)"t do with just visual information. Statistical learning: study: familiarize certain stimuli together, tested new objects where certain features are separated, statistical learning is incredibly important for language-learning.
