本研究旨在釐清年齡因素對我國國小學童注意力表現之影響，並進一步探究國小階段學生於集中性、持續性、選擇性、交替性與分配性等注意力向度的發展趨勢。研究者透過「國小兒童注意力測驗」比較1213名國小一至六年級學童於不同注意力向度之表現。研究結果顯示，年齡因素的確對國小學生的注意力表現產生顯著影響；其中，交替性注意力是國小學生成長蘊釀週期最短的注意力向度，幾乎每年都可呈現顯著成長。集中性、選擇性與分配性等注意力向度則每隔一年就進入成長蘊釀期，呈現規律性的成長趨勢；持續性注意力則有待未來執行更長期研究，以確認此注意力向度的成長趨勢。本研究結果有助於釐清不同注意力向度的發展歷程。

This paper aims to clarify the effects of age on attentional performance and explore the development trends of focused, sustained, selective, alternating, and divided attention among primary school students in Taiwan. "The Attention Test for Primary School Student" was employed to assess and compare the performance of 1213 primary school students in each dimension of attention. Results showed that primary school students' attentional performance significantly varies by age; development of alternating attention is characterized by the shortest incubation period and significantly improves year by year; development of focused, selective, and divided attention requires a longer incubation period every other year and also exhibits a regular growth tendency; the trend in development of sustained attention may not be confirmed without further observation over a longer period of time. The results of this paper can help clarify the development process of each dimension of attention.
