In a previous letter to the parent(s) of children with developmental apraxia of speech (DAS), the speech characteristics often exhibited as part of the disorder were described. In this second letter, the issues involved in current thinking about the nature of the disorder are explored. Also shared is information concerning what is thought to be known about the causes of the disorder. An appendix of publications exploring these issues appears at the end of the letter.

Shaped Section

My dear Dr. Sharpey,—In my memoir on Calamites, published in the last volume of the ‘Philosophical Transactions,’ I gave two figures of sections of a plant (plate 25. fig. 16 and plate 28. fig. 39) supposed to be a Calamite, but respecting the Calamitean nature of which I expressed my doubts in a note at the foot of page 488. I have now got numerous examples of this plant, and it proves, as I surmised, to belong to a distinct type. It has a branching stem, not jointed, and having a remarkable pith. Since the latter organ, when divided transversely, gives a star-shaped section, closely resembling that of a Calamite, except that it has not been fistular, I propose to give to the plant the generic name of Astromyelon . I have further examined a series of curious stems which I described briefly at the Edinburgh Meeting of the British Association under the name of Dictyoxylon radicans ; this plant I also find must be placed in a new genus. It is characterized by possessing an exogenous, woody, branching stem, composed of reticulated vessels. It has no pith, and its bark consists of cells arranged in columns perpendicular to its surface. I think it not ‘improbable that this has been the subterranean axis of some other plant, since I have succeeded in tracing its ultimate subdivisions into rootlets. I propose for the present to recognize it by the generic name of Amyelon . My specimens of this plant are very numerous, some of them having been kindly supplied to me by Messrs. Butterworth and Whittaker, of Oldham. They may prove to be rhizomes and roots of the Asterophyllite described in my last letter to you. Of this last genus I have just got an additional number of exquisite examples, showing not only the nodes but verticils of the linear leaves so characteristic of the plant . These specimens place the correctness of my previous inference beyond all possibility of doubt, and finally settle the point that Asterophyllites is not the branch and foliage of a Calamite, but an altogether distinct type of vegetation having an internal organization peculiarly its own. This organization is identical in every essential point with that of my Volkmannia Dawsoni already referred to in my previous letter, and which I do not now hesitate to designate Asterophyllites Dawsoni . The peculiar triquetrous form of the young vascular axis of this genus is too remarkable and too distinct from that of all other Carboniferous types to be mistaken for any of them, and especially for that of Calamites, with which it has not one single feature of real affinity.

Science Article

The following article has been retracted by the Editor and publishers of Psychological Science at the request of the lead author, Lawrence J. Sanna: Sanna, L. J., Chang, E. C., Parks, C. D., & Kennedy, L. A. (2009). Construing collective concerns: Increasing cooperation by broadening construals in social dilemmas. Psychological Science, 20, 1319–1321. doi:10.1111/j.1467-9280.2009.02458.x In a letter to the Editor (Eric Eich), Dr. Sanna wrote: The data reported in this article are invalid and should not be considered part of the scientific literature. The responsibility for this problem rests solely with the first author, Lawrence J. Sanna. Coauthors Edward C. Chang, Craig D. Parks, and Lindsay A. Kennedy are in no way responsible for this problem. In response, the Editor noted that Psychological Science follows the retraction guidelines developed by the Committee on Publication Ethics (COPE). Dr. Sanna was urged to follow these guidelines carefully in drafting a retraction notice, particularly with respect to stating the reasons for the retraction, to distinguish misconduct from honest error. To assist Dr. Sanna with this task, the Editor provided Dr. Sanna with a copy of the COPE guidelines ( http://publicationethics.org/resources/guidelines ) and a link to a retraction notice that was published in Psychological Science last year. This notice was considered a "model" by Retraction Watch, and Dr. Sanna was advised that, in keeping with this notice, he "must specify clearly the reasons for the retraction in such language that all of your coauthors agree to it." While awaiting Dr. Sanna's reply, the Editor sought to contact Dr. Sanna's three coauthors. Although one coauthor was aware of Dr. Sanna's request to retract the 2009 Psychological Science article, the other two were not. All of the coauthors have agreed to retraction of the article, and each has received a copy of this notice. Dr. Sanna replied by noting with regret that "research errors" have made it necessary for him to request retraction. The letter concluded with the following: "At the direction of legal counsel, I am unable to say anything further than that contained in my previous letter at this time." Because it is unclear when, if ever, details on these research errors will be forthcoming, the Editor owes it to the journal's readership to retract the article now, even though this notice does not reflect COPE guidelines or journal policy.

I have been following with great interest the discussions on the above topic which have been published in several journals. On reading a recent letter to Nature by Professor Herbert Dingle (1957) in reply to a previous letter by Sir Charles Darwin (1957), I noticed that it is feasible to perform astronomical observations which could provide an experimental basis for choosing between the two points of view. In fact, these observations may have already been made.

The editor of Pediatrics kindly responded to my previous letter which questioned the safety of gastrostomy for facilitating the feeding of "low intake" premature infants without surgical disease. We agree with his judgment that the use of general premature mortality statistics may not be appropriate for a "select" group of "low intake" premature infants but hasten to add that the higher mortality rate of the gastrostomized premature infants may have been related to the surgical procedure.
