We investigated the evidence for subtypes in children with difficulty processing and integrating sensory information. Fifty-seven articles were incorporated into a systematic literature review; only 4 articles provided direct evidence for subtypes. These studies did not provide a comprehensive assessment of all sensory functions and sensory-based motor functions (i.e., praxis) and included different diagnostic groups. Therefore, generalized conclusions about subtypes could not be drawn. The other 53 studies reviewed provided meaningful information about strengths and challenges that children with difficulty processing and integrating sensory information demonstrate, but these studies were limited in scope. A principal theme was the importance of conducting comprehensive assessments of sensory-based functions, including multiple measures of sensory integrative functions such as praxis, sensory modulation, and sensory discrimination in children and adolescents with various clinical disorders. In addition, more consistency in the use of specific assessment tools will allow for synthesis of data across studies. Davies, P. L., & Tucker, R. (2010).

Background: Efficient word identification is directly tied to strong mental representations of words, which include spellings, meanings and pronunciations. Orthographic learning is the process by which spellings for individual words are acquired. Methods: In the present study, we combined the classic self-teaching paradigm with eye tracking to detail the process by which complex pseudowords are learned. With this methodology, we explored the visual processing and learning of complex pseudowords, as well as the transfer of that learning. We explore visual processing across exposures during the initial reading task and then measure learning and transfer in orthographic choice and spelling tasks. Results: Online eye movement monitoring during the repeated reading of complex pseudowords revealed that visual processing varied across exposures with key differences based on word type Further, data from both dictation and eye movements recorded during the orthographic choice task suggested stronger learning of morphologically than orthographically complex pseudowords after four encounters. Finally, results suggested that learning transfer occurred, with similar levels of accurate recognition of new pseudowords that were morphologically or orthographically

We present here a review of recent research on the role of metalinguistic and socio-cognitive factors in reading skill. We first review research how morphological awareness and orthographic processing impact the acquisition of reading skill. We show that the first might account for change over time, and the second may not. We then turn to our new studies examining the interplay between these two factors in reading development. In each of these domains, we test predictions of theories of reading development. Finally, we turn to research on a very different set of variables, which we term socio-cognitive. We explore the factors that support academic outcomes for university students with a history of reading difficulties, including the role of a range of coping strategies and support services. Together, we hope that this review inspires new inquiry into understanding the factors that underlie successful reading acquisition. Key words: morphology, orthography, students with a history of reading difficulties We review here recent research on the role of metalinguistic and socio-cognitive factors in reading skill. This is a joint effort with two young researchers, and we focus primarily, though not exclusively, on research from our lab. Together, we describe collaborative research that has allowed us to explore learning across various domains and developmental stages.
