The neural basis of nonword repetition in children with developmental speech or language disorder: An fMRI study

Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article. Please note that, during the production process, errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain.

Functional organisation for verb generation in children with developmental language disorder

“…Although some differences can be observed when lowering the threshold, these are not in the areas where we predicted differences, and we believe that a threshold of Z > 3.1 is appropriate when considering our sample size (interested readers can independently assess these maps at https://identifiers.org/neurovault.collection:8615 ). Our negative findings at the group level are consistent with those from a recent study of DLD and developmental speech sound disorder, which also suggested these groups had similar patterns and levels of brain activity to those seen in typically developing children ( Pigdon et al., 2020 ).…”

“…Tasks that involve sequential learning, such as learning the form of a novel word, may be better suited to revealing differences in these regions. (but note that Pigdon et al., 2020 reported no differences in brain activity for nonword repetition in children with DLD). Our task was also very short; it is possible that having more trials and consequently better estimates of activity would reveal more subtle differences (however, the trade-off here is that children are less likely to tolerate longer tasks and more likely to move).…”

Altered engagement of the speech motor network is associated with reduced phonological working memory in autism

“…Therefore, research in other language disorders will provide greater clarification for the specific and shared neural substrates underlying a common behavioral hallmark (cf. Pigdon et al, 2020 , Liégeois et al, 2011 ).…”

Consistency of children’s hemodynamic responses during spontaneous speech

“… ) to determine effects [e.g., Refs. 31 , and 39 – 42 ]. Thus, investigating the consistency of HRs over trial segments that included up to 10 trials was warranted.…”
