Th...I should read the .pdf file before commenting. Then again, there's probably a lot of things I should do, but don't.<BR/><BR/>Wouldn't others think there's an inherent difference between Gs and NA tasks? I think that's what moved our conceptualizaton of NA as a subset of Glr, rather than Gs. <BR/><BR/>Oh it involves speed, but Gs tasks are usually always novel. Our every day routines do not have us searching for identical numbers or that the number two had this symbol (those who have been triennialed to death excluded of course.) <BR/><BR/>I think there is key difference between cognitive fluency and Gs (and it's not just the motor component...I think the academic fluency measures of the WJ-III are truly not Gs measures.) <BR/><BR/>I guess long story short-one seems to be highly dependent on rate of recall from LTM while the other is a pure rate of cognitive processing speed. Perhaps the latter is needed for the former, but I do not think the converse is necessarily true.<BR/><BR/>Probably best not to ask what I think ;-)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-11327954.post-1112123887847562852005-03-29T11:18:00.000-08:002005-03-29T11:18:00.000-08:00Good question.

I think it is largely a matter of releative degrees of controlled or automatic processing.<BR/><BR/>Gs and NA tasks, given that they are timed, place a premium on efficient automatized performance. Also, by definition, most all Gs tasks are comprised of items of easy to moderate (at best) difficulties, items that almost everyone would get correct if there were no time limits. The lack of difficult items, which is what is found on "level" measures (vs "rate" or "fluency" measures), is probably the key to considering these tasks as "more" automatic......what do others think?Kevin McGrewhttps://www.blogger.com/profile/07945625852793502565noreply@blogger.comtag:blogger.com,1999:blog-11327954.post-1112118523187898942005-03-29T09:48:00.000-08:002005-03-29T09:48:00.000-08:00In what sense are the Gs and Naming Facility tasks...In what sense are the Gs and Naming Facility tasks "automatic?" They seem to involve a fair amount of controlled processing to me.Anonymousnoreply@blogger.com
