The term "intellectually gifted rural-to-urban migrant children" refers to intellectually gifted children who are in migration from rural to urban areas. We compared performances on seven attention tasks among intellectually gifted (n = 26) and average (n = 30) rural-to-urban migrant and intellectually gifted urban children (n = 31). Our results showed that intellectually gifted rural-to-urban migrant children performed more correctly and faster on some attention tasks than did the intellectually average rural-to-urban migrant children, but they did not perform as well on some attention tasks as did the intellectually gifted urban children. Based on the attentional structures, it was evident the intellectually gifted rural-to-urban migrant children developed more mature than did either the intellectually gifted urban or the intellectually average rural-to-urban migrant children. This suggests the intellectually gifted rural-to-urban migrant children's attention is overall superior to that of their intellectually average peers. However, there are advantages and disadvantages in terms of the quality of their attention compared to the intellectually gifted urban children. While their attentional structures seem to develop earlier, their accuracy on some of the attention tasks seems to suffer. This suggests that rural-to-urban migration is a double-edged sword for intellectually gifted children.
