TABLE 4.

Descriptive data for the temporal distributions of matched verb-action instances by group and agents.

Figure	Group	Agents	Mean (SD)	Mode	Skewness (SE)	Kurtosis (SE)
Figure 2	Group 1A	All	1.9 (18.3)	0	−0.01(0.08)	1.64 (0.16)
	Group 2B	All	3.2 (19.2)	0	0.14 (0.07)	1.67 (0.14)
Figure 3	Group 1A	Mother verb–Mother action	0.78 (19.3)	0	−0.01(0.11)	1.22 (0.22)
	Group 1B	Mother verb–Child action	3.48 (16.7)	0	0.08 (0.13)	2.54 (0.25)
Figure 4	Group 2A	Mother verb–Mother action	4.11 (18.3)	0	0.23 (0.10)	1.90 (0.21)
	Group 2B	Mother verb–Child action	2.82 (19.8)	0	−0.08(0.10)	1.47 (0.21)
	Group 2C	Child verb–Child action	−0.22(18.4)	0	0.32 (0.22)	2.72 (0.43)
	Group 2D	Child verb–Mother action	4.26 (21.4)	0	0.65(0.24	0.92 (0.47)

Participants, sessions, and situations are aggregated. Skewness values between −0.5 and 0.5 indicate that the distribution is approximately symmetric; kurtosis values greater than +1 indicate that the distribution is too peaked.
