本研究运用认知心理学信息加工的实验方法，探讨了小学儿童对习俗时间(星期)的认知加工过程的发展。研究结果表明:小学儿童的认知加工成绩呈现随年龄而提高的趋势;“时距”因素及“边界”因素对认知加工过程产生了显著的影响;儿童认知加工过程的发展是从逐一计数和推算的加工方式向数字运算和表象加工的方式发展，表现出由具体向抽象的发展趋势;同时还发现，儿童对习俗时间(星期)的认知加工具有文字符号的制约性。

    In this study，The researcher applied cognitive methods to re-search the deveolpment of primary school children's cognitive pro-cessing about the conventional time (week).The results indicated:
    (1)The achievement of cogntive processing about the conven-tional time (week) develops with the increasing of age.
    (2)The factors of duration and boundary affected the cognitive processing about the conventional time (week)significantly.
    (3)The pattern of cognitve processing about the conventional time (week)develops from recitation and inference to numeral cal-culation and image process，it shows a tendency to develop from concrete to abstract.
    (4)The cognitive processing about the conventional time (week)is confined by language symbol.
