This article explores Social Information-Processing [SIP] that underlie care behavior of elementary school children. The subjects were adopted by clustered sampling from the Pingtung area. The results reveal several important conclusions. First of all, most of children experienced six stages of SIP, so the approach was the cognitive basis when meeting the caring surroundings. Some children need to improve their SIP ability that they can't handle it smoothly. Meanwhile, children need more instructions to perform better flexible, matured, and reasonable pattern of care behavior. We may consider seriously how to add self- protection mechanism for children among the SIP. When children conduct the care behavior they need not only to empathy others, but also to have the ability of social information-processing, therefore, it is more reasonable to adopt an integrated model of emotion processes and cognition in social information processing for understanding the care behavior of children. Furthermore, the results also provide some valuable application for life education. Both of teachers and parents can design curriculum that would assist children to experience and increase suitable care behaviors, and establish the humanistic cultivation in time for children. Finally, further research is expected that we could conduct different approach and design to clarify the social information-processing issue of children's care behavior.
