Here we aimed to 1) show that being read a mirror-printed picture book is able to change lateral biases in counting; 2) trace the development of preliterate biases; and 3) test the role of mental model construction processes. Spanish-speaking 3 and 4 year-olds (N = 155, white, 87 female) carried out a task of counting a row of objects and a task in which they built a toy scene before and after being exposed to a mirror-reversed storybook. The left-to-right or right-to-left direc­ tionality of their responses was recorded. Only the older group showed pre-test lateral biases. The mirror book changed the lateral biases in counting, and induced a congruent, but smaller change in the model construction task. The two tasks did not correlate, against the implication of shared mechanisms in them.}, organization = {MCIN/AEI/10.13039/501100011033(PSI2015-67531-P and PID2021-126589OB-I00)}, organization = {ERDF (European Regional Development Fund)}, publisher = {Elsevier}, keywords = {Mental number line}, keywords = {Preliterate children}, keywords = {Development}, title = {Do picture books affect counting directionality in preliterate children?
