Hypothesized model.
Table 1.
Definitions of coded prosocial behaviors and affiliative behaviors.
Fig 2.
The occurrence rate of prosocial behavior from recipient child to initiating child in PP and MC sessions.
Data are represented as session means of the occurrence rate of prosocial behavior for each context. ***: p < .001. The p value was calculated from the estimated value in Analysis 1 (Model 1).
Table 2.
Influence of independent factors on the proportion of sessions in which prosocial behavior were occurred from recipient children in Analysis 1, in Model 1.
Fig 3.
Frequency of affiliative behavior from recipient child to initiating child in PP and MC sessions.
Data are represented as session means ± 1 SE of the frequency of affiliative behavior for each context. ***: p < .001. The p value was calculated from the estimated value in Analysis 1 (Model 2).
Table 3.
Influence of independent factors on the number of affiliative behavior were occurred from recipient children in Analysis 1, in Model 2.
Fig 4.
The effect of context on direct reciprocity through positive emotions (n = 622).
***: p < .001. The values in parentheses represent direct effect before controlling a mediator.
Fig 5.
Number of recipient child’s first prosocial behavior to initiating child within 10 minutes of initiating child’s prosocial behavior.
