“…Spatial words parents and children produced were also coded using an adapted version of the System for Analyzing Children's Language about Space (Cannon et al, 2007)-a manual for identifying and categorizing spatial words and phrases in English. Coding was modified based on prior work (Pruden et al, 2011;Kisa et al, 2019) examining the spatial language use in parents and children. We used six categories: (1) dimensional adjectives that describe the size of a person, place or thing (e.g., big, tall, little), (2) spatial feature terms that describe properties of nondimensional aspects of objects (e.g., bumpy, corner, flat), (3) positional and directional terms that describe the relative position of a person or thing in space (e.g., around, top, between), ( 4) shape terms that are used to label any 2D or 3D enclosed spaces (e.g., circle, sphere), ( 5) orientation and transformation terms that describe the relative orientation or transformation of objects in space (e.g., turn, rotate), and ( 6) continuous amount terms that describe the amount of continuous quantities (e.g., whole, half, part).…”
