2021 NeuroImage  
The at-risk children improved equally to their peers in overt repetition of recurring new word forms, but were poorer in explicit recognition of the recurring word forms.  ...  (Nora et al, 2017, Children show right-lateralized effects of spoken word-form learning.  ...  The current results indicate that dyslexia risk children were able to construct phonological memory representations of the new phonological word forms similarly as control children after multiple occurrences  ...

The Hypothesis of Unexplained Brain Damage and Learning Difficulties

Theofilidis Antonis, Auctores Publishing LLC
2021 Neuroscience and Neurological Surgery  
Many of the theories developed around the problems of children with learning disabilities have focused on specific areas of the brain that may be dysfunctional.  ...  It is, in other words, the area in the left hemisphere of the brain that is responsible for the written form of speech.  ...  that deficient readers at slow or delayed reading make eye movements that are smaller in size compared to normal readers, last longer and form a schematic representation similar to that of the normal  ...

A Mini-Review: Toward a Comprehensive Theory of Dyslexia

John R Kershner
2015 Journal of Neurology and Neuroscience
