The purpose of this study was to evaluate the reliability and validity of the Korean version of Maternal Behavior Rating Scale(MBRS) and Child Behavior Rating Scale(CBRS) by Mahoney(1999) and confirm an appropriate manual and procedure for its use in Korean. The study consisted of a sample of 77 parent-child dyads, in range of 8 to 75 months of age. Parent were videotaped while playing with their children with a standard set of developmentally appropriate toys during about 10 minutes. These observations were coded with the Korean Maternal Behavior Rating Scale to asses mother's style interaction and Korean Child Behavior Rationg Scale to assess children's pivotal behavior. Collected data were coded by two raters independently with the items of K-MBRS & K-CBRS on a 5-point Likert scale. The results were as follows; First, K-MBRS and K-CBRS had sufficient internal reliability, Cronbach α of K-MBRS was .86. and K-CBRS was .81. Second, the result of factor analysis indicated that K-MBRS accounted three factor model, while two factor model is the best for the data of K- CBRS. Third, in addition this study was to analyze the effect of maternal interactive style over children's ages. As a result, maternal 'responsive behavior' and children's 'activity behavior' factor had an impact on children's age. However the younger their children are, the more responsive mothers were to interact with their children.

Preschoolers' understanding of moral, social-conventional, and personal domains was examined with 4- and 5-year-old children. Children evaluated moral, social- conventional, and personal events on six criteria - non-permissibility, seriousness, rule independence, personal choice, generalizability and locus of control, and also provided the justification for their judgment. On all criteria, 4-year-old children distinguished the events from three domains and 5-year-old children only distinguished personal events from either moral or social-conventional events. However, they made clear distinctions among three domains in terms of justifications of their judgments. Most children judged that parents should make decisions about moral, social-conventional, and personal events, but only some 5-year-old children thought children should make decisions about personal events.

The purpose of this study was to analyze the effects of the level of perceived importance of the intention and of the level of cognitive resource demanding on the development of performance for the prospective memory. Five, seven, and nine-year old children participated. The 1st experiment was designed to examine the effects of the level of perceived importance of intention. As a result, the prospective memory became significantly higher with age and with the perceived important of intention. The 2nd experiment was designed to find out the causes of the failure of performing the prospective memory even when the perceived important of intention was high. As a result, the higher the level of cognitive resource demanding was, the lower the prospective memory was. This result was interpreted as that the more cognitive resource demanding was, the more short-term capacity decreased. The present results suggest that perceived importance of intention is important for the success of prospective memory, but perceived important of intention is not enough to perform two or more task, thus a certain level of cognitive abilities is needed to distribute attentional resource for the tasks.
