Figure 1

Twenty-four-month-old child’s rib cage and abdominal movement, and corresponding rmoving and classification of moment-to-moment relationship during rest (upper panel) and vocalization of “you take big bite” (lower panel). The solid line (—) indicates movement of the abdomen, and the dashed line (- - -) indicates movement of the rib cage. The rmoving value is identified with a dark dot (CI = coupled inspiration), a light dot (CE = coupled expiration), an “x” (RCE = rib cage expanding), and a “+” (AE = abdomen expanding). For clarity, points in the unspecified (UN) classification are not plotted. Upward on the y-axes indicates increasing circumference.
