This study shows day-old chicks associate small numbers with left space and large numbers with right space, but not physical size with space.

The study tests the Bouba-Kiki effect in three-day-old chicks, finding they associate spiky shapes with 'Kiki' and round shapes with 'Bouba', suggesting an innate perceptual mechanism.

This study investigates how symbolic and non-symbolic numbers influence spatial perception in a number-line bisection task, finding distinct biases for each format.

This study shows that brain lateralization in newborn chicks affects their ability to develop a left-to-right mental number line, linking spatial and numerical processing.

The paper shows that newborns associate smaller numbers with the left and larger numbers with the right, suggesting an innate spatial-numerical association.
