Table 1.

Sample coding of two individuals' speech and gesture (one individual from each spatial group). Each sentence was transcribed and coded for the type of information (static vs. dynamic) it conveyed. The location of each gesture was marked by a number in the speech transcript), and each gesture was classified according to type (pointing vs. iconic), referent (static vs. dynamic), and its relationship to speech (same or different information).

Group	Speech	Speech Coding	Gesture	Gesture Coding	Gesture-Speech Match
Low-spatial Ability	I just moved [1 the one on the right] [2 a little bit] to [3 more downward] and they look the same	Static: The one on the right Dynamic: A little bit to more downward	Index finger pointed at the right block Index finger moved towards left a little bit Flat hand facing down moved in a downwards motion	Pointing-static Iconic-dynamic Iconic-dynamic	Match Match Match
High-spatial Ability	Flipped [1 the left one] again, [2 rotated it] about 45 degrees, [3] put them together in my head and found that they're the same	Static: The left one Dynamic: Rotated it about 45 degrees	Index finger pointed at the left block Loose hand facing right moved in semicircle in clockwise Index finger pointed at the blocks	Pointing-static Iconic-dynamic Pointing-static	Match Match Mismatch
