I assume this means a child has a difficulty memorizing a random list of things, like state capitals, spelling, meaning of words. Never been diagnosed with this but it wouldn't surprise me. I have an extremely hard time with remembering people's names, or any other random list of stuff. This has made if very difficult to learn a new language. Back in H.S. when I was trying to take a language I would totally frustrate a tutor because I couldn't seem to remember a work she had only told me the meaning to only minutes before.
Although I see this problem in myself, I don't have a lot of clue what to do. I always just learned to compensate by being strong in other area's of learning. Math comes easy to me, so I learned "math facts" but understanding their patterns more than memorizing them. I didn't have to "memorize" science vocabulary if I learned to understand the science behind it. I could never understand what I was saying in the foreign language but I had an excellent understanding of the grammar. I can learn things if I extensively USE them, and then they are mine for good. I could probably recite all the different commands necessary to use unix to this day even though I haven't touched it in years.
Thankfully neither of my children have that problem.
