I have just read a paper written as a response to the Rose Review by one of our Whole Language friends who speaks with the authority provided by the United Kingdom Literacy Association (UKLA). The paper claims to "unpicks and questions the thinking behind a diet based on SVR" (Simple View of Reading).
It would be interesting to know what this paper is. Is it on-line?

Thank you, Yvonne. Their replies are very helpful.
Funnily enough, this paper was flagged up on TES by our old friend, dolfrog.
Functional Neuroimaging Insights Into the Development of Skilled Reading
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2741313/I found this particularly interesting:

One potentially powerful application of information derived from the developmental neuroscience of reading is for the investigation of the neuroscience of adult reading. Developmental phenomena observed in a particular set of regions, for example, can help to frame specific questions about those brain regions in adults. As a case in point, recall the earlier-mentioned finding that there is decreased activity observed in adults compared to children in a left temporal-parietal region for reading aloud high-frequency words
This result was interpreted to indicate that this decrease in activity comes about because of the decreasing reliance on phonological mechanisms for high-frequency words that comes with reading skill and age. If this interpretation is correct, then, in principle, the “child-like” level of activity should be able to be resurrected in adults when they are presented with more phonologically challenging stimuli in the same task structure. Two factors that have been shown to increase the phonological demand of visually presented words are length (i.e., serial length of words measured as number of letters) and familiarity (i.e., a measure of usage).
Therefore, in an fMRI experiment, we (Church, Petersen, & Schlaggar, 2006) examined two levels of familiarity (low-frequency words and pronounceable nonwords) and two levels of length (one-syllable, four- to six-letter stimuli, and three-syllable, seven- to nine-letter stimuli) in 24 healthy adults (age range = 21–30 years). Low-frequency words and nonwords produced stronger activation in the left temporal-parietal region than did high-frequency words. Most importantly, the length of low-frequency and nonwords modulated the activity increase with longer strings leading to greater activity. In other words, manipulation of stimulus features produced a child-like level of activity in a region previously shown to be developmentally transient in its involvement in reading aloud of single words (Church et al., 2006). This preliminary result lends further support to the idea that this particular region in the left temporal-parietal cortex region is functioning as a phonological processor.
More generally, the results of this manipulation suggest that regions that have the appearance of developmental transience for a particular reading-related function are not necessarily uninvolved in these processes in adults; the brain remains flexible, calling on apparently more developmentally significant regions in order to deal with more challenging stimuli.
