partialed out, prereading skills

Question

Hello, I do not understand this:Research has shown that knowledge of nursery rhymes among three-year-olds was a significant predictor of later prereading skills even after the childrens´ IQ and their mothers´ educational levels were partialed out.Could "partial out" mean "take into account"? - If scientists considered also the IQ and their mothers´levels, the knowledge of rhymes was still an important thing in the development of prereading skills.What are prereading skills. I can imagine the skill of reading, but what are prereading skills?Thank you for your help                   Mowgli

Hi,

I've never heard 'partialed out' However, I googled it and got quite a few hits. eg

When the effects of the ...... variable are removed, they are said to have been partialed out.

So it means 'removed' rather than 'taken into account'. I would perhaps have said 'factored out' or 'allowed for'.

As regards prereading skills, I would have guessed, for example, learning to read and sound out the alphabet. I googled the phrase and, again, got a lot of hits. eg

Prereading skills are stimulated in a systematic way such as identifying and discriminating sound-patterns at the level of the word, the syllable and the segments, and children are helped to categorize forms, to discriminate and understand pictures, to recognize the direction of reading, and to realize the grapheme-phoneme correspondence.

and another eg

Listening to music also teaches important prereading skills. As youngsters use small drums or other percussion instruments (homemade or store-bought), they can play the rhythmic pattern of words. They can learn to hear the differences between fast and slow, loud and soft, one at a time and together, etc. When they try new instruments, they notice how each variation changes the music.
