Properties of PWs across age groups.

Age group and
range (in years)		 % PWs in
FnCFm form		 % overall
disfluencies in
FnCFm PWs		 % PWs with
disfluencies
on post-F		 % PWs with
disfluencies on
both F and C		 Mean age
of the group
(in years)
G1 (3–5) 54.11 95.01 0.41 2.83 4.4
G2 (6–9) 59.77 97.85 0.00 2.27 8.7
G3 (10–11) 63.16 95.98 0.03 2.38 10.4
G4 (12–16) 62.39 96.30 0.09 2.93 13.8
G5 (20–68) 59.74 93.05 0.17 2.31 39.3

Note. Column 1: age group and the corresponding age range. Column 2: the percentage of PW that had initial and final function words. Column 3: the percentage of the overall disfluencies included in the PWs given in column 2. Columns 4 and 5: the percentages of PW that were dropped due to the two exclusion criteria (the column 4 exclusion criterion is a disfluency on a function word that followed the content word; the column 5 exclusion criterion is disfluency on both an initial function word and the content word. Column 6: the mean age (in years) of the group.
