This study investigated how lower grade elementary school children and their parents respond differentially in different types (domains) of parent-child conflicts. The participants were 34 lower grade elementary school children (average age of 7.83) and their parents. An observation method was used: the parents were asked to record four different sessions of parent-child interaction using a voice recorder for a total duration of two hours. The acquired information was coded and analyzed in terms of conflict domains and response types. The findings were as follows: (1) In all four domains, the first and second most frequent parents’responses were the demanding and inductive response. (2) In all four domains, the first and second most frequent r e s p o n s e s i n c h i l d r e n w e r e t h e r e j e c t i n g a n d a r g u m e n t a t i v e r e s p o n s e s . ( 3 ) I n t h e a c h i e v e m e n t a n d p r u d e n t i a (l T o authors: safety?)domain, a positive correlation was found between parents’power assertion and children’s fighting response; in the moral-convention domain, a negative correlation was found between parents’power assertion and children’s argumentative response; in the personal domain, a negative correlation was found between parents’power assertion and children’s rejecting response. This study suggests that, in parent-child conflicts, special attention must be paid to the different meanings and effects of parental power assertion in different domains.
