The research also found significant differences between the swimming groups and non-swimmers regardless of socio-economic background.

　　While the two higher socio-economic groups performed better than the lower two in testing, the four SES(美国工程科学协会)groups all performed better than the normal population.

　　The researchers also found there were no gender differences between the research groups and the normal population.

　　As well as achieving physical milestones faster, children also scored significantly better in visual-motor skills such as cutting paper, colouring in and drawing lines and shapes, and many mathematically-related tasks. Their oral expression was also better as well as in the general areas of literacy and numeracy.

　　The study is a joint project between Griffith University, Kids Alive Swim Program and Swim Australia. (281W)
